Complete guide to business security camera systems

June 1, 2022

When setting up the infrastructure for a new business, business security cameras are one of the first components that come to mind. However, your security cameras are only part of the needed security infrastructure. Focusing on the entire commercial security camera system will result in both a higher level of security and a greater return on your security camera investment.

In this article, we explain the concept of business security camera systems, what goes into them, and why you need one. We start with the definition and components of the system. Then, we go through a real-life use case on building a business security camera system based on a floor plan.

If you have any questions about how to build a powerful business security camera system for your sites, please reach out for a demo of Solink’s VSaaS platform.

What is a business security camera system?

A business security camera system is the entire video security ecosystem. It includes not only your security cameras but also all the hardware and software components that help you maximize the value of your security cameras.

What are the components of a business security camera system?

A business security camera system has four main components:

  • Business security cameras
  • Data storage
  • Internet connection
  • Video analytics

This list is very specific to the commercial security camera system components. However, this can also be a part of your loss prevention system, which includes many of the other pieces of hardware you might expect to see, such as your POS, RFID tags and gates, and so on.

Business security cameras

Security cameras are the basis of the system. Most commercial sites require some form of video surveillance. The same is true for offices, university and college campuses, and more. However, if you stop at simply buying security cameras, then you are left with an underutilized and incomplete infrastructure.

Data storage

Some cameras have data storage in them, but it is usually limited. Other cameras store directly to the cloud, which is great if you have the bandwidth and a good connection with zero downtime. Generally, you will need either a DVR (digital video recorder) or NVR (network video recorder) system to function as your data storage device. We briefly touch on DVR vs. NVR below, but you should take a look at our main comparison article for a complete breakdown of their similarities and differences.

These systems can be customized to meet the specific video retention needs of your business. Whether you need 15, 30, 90, or more days of onsite video storage, Solink can accommodate your requirements.

Internet

We live in a connected world, which means an Internet connection is always going to add functionality to your infrastructure. In the case of a business security camera system, the Internet allows for remote backup, remote access to your cameras, and a lot of other benefits that greatly improve the efficiency of users.

For example, Solink automatically updates all of the software on our systems. In addition, Solink runs automated security camera health checks to tell you if your cameras have gone offline or are blocked in some way.

Video analytics platform

Video analytics is critical in a modern business camera system. Cameras are rich data sources that go well beyond the security domain. Collecting and storing but not putting into action that data can make every business decision harder. Here are just some of the ways Solink’s video analytics platform can help you.

Security related:

  • Match video clips to potentially suspicious transactions by integrating security cameras with your POS (voids, cash refunds, high discounts, zero-dollar transactions, etc.). Solink doesn’t require a text inserter box to do this.
  • Use motion search to see all activities in an area to quickly track down an event.
  • Use Solink’s Video Alarms feature to create time-based perimeter defenses, protecting your business when you aren’t there.
  • Be alerted when specific transactions, items, or criteria are met.
  • Receive a notification when individuals enter certain areas of your business.

Non-security related:

  • Audit your stores for regulatory and company policy compliance (e.g., make sure emergency exits are cleared and stores are clean).
  • Modify store layout based on customer heat maps so the best products are in the best locations.
  • Ensure customer service expectations are being met (e.g., reducing wait times in queue) by identifying retraining opportunities.
  • Monitor events such as slip-and-falls.
  • Ensure brand standards and cleanliness.
  • Determine store efficiency with guest counting.

Why do you need a business security camera system?

Business security camera systems provide benefits to your business. Here are just a few of the things you can expect to get out of your system.

Reduce inventory shrinkage

Well placed cameras and a strong video analytics platform give you the ability to scan a full day worth of video footage in minutes. This can help you find inventory shrinkage in all of its forms, from employee theft at the POS to shoplifting, organized retail crime (ORC), and inventory not showing up or leaving out the loading dock.

Remote video monitoring

Remote video monitoring offers significant value add and we have an entire other article dedicated to the topic. Being able to monitor all of your locations from the corporate head office, or even your home, means better control on the day-to-day operations of all your sites.

Enhance safety

With a recent trend of increased violent crime, ensuring the safety of your staff, customers, and premises is becoming a priority. However, safety doesn’t just mean from potentially violent encounters. A well-connected and monitored commercial security camera system will improve safety in other ways. By monitoring company and regulatory compliance, you can make sure emergency exits are clear, wet floor signs are out to prevent slip-and-falls, and visitors aren’t entering restricted areas such as kitchens or warehouse space.

Optimize operations

Heat maps of your stores can tell you where customers are gravitating. Placing the best merchandise in the locations where customers naturally go can increase revenue. Making sure your employees are actively helping patrons can do the same. These are just two of the ways your business security cameras can optimize the operations of your stores.

Receive alerts

Some events are just too high risk to search for after the fact. Setting up the Solink Video Alarms system means you will get alerts when motion is detected outside of normal business hours. Then, you have the ability to see what is happening in real time before deciding to dispatch emergency services. This improves your perimeter security while reducing the risk of fines due to false alarms. You can also receive alerts when someone enters a sensitive area of your business even during working hours.

Some transaction types have a higher risk of fraud. You can be notified when these transactions occur so you can view the related video immediately.

Document events

This is another reason video retention is a key component of business security camera systems. Being able to store video footage of specific events forever can help improve your case management process. On the Solink platform, you can send footage of events directly to managers, insurance companies, the police, or any email address you want.

Saving events can help enhance many other aspects of your business. For example, video evidence of internal theft can be used as part of your loss prevention onboarding training. Conversely, you can capture footage of employees providing excellent customer service to praise them during your next staff meeting.

What are the main types of business security cameras?

There are many different types of commercial security cameras. Let’s break down all the specific definitions. Here’s a helpful article from the Solink Help Center if you are unsure about what kind of security cameras you have.

CCTV cameras

Closed-circuit television (CCTV) is simply the opposite of broadcast TV. Whereas broadcast is aimed at sending video to many subscribers, CCTV transmits video to a small number of places. CCTV is sometimes synonymously used with video surveillance for this reason.

Commercial CCTV security cameras originally sent their video to the security office locally, but now they are usually connected to the Internet so their footage can be viewed remotely by more stakeholders, including managers, loss prevention specialists, insurance companies, and even emergency services dispatchers.

Analog cameras

Analog cameras can sometimes be considered old technology when compared to newer IP cameras. For example, analog security cameras are usually capped to standard definition (SD) video quality. However, they tend to be reliable and have been the mainstay of video surveillance for decades. They normally require a coaxial cable connection to transmit video along with a power cord, but RF wireless analog cameras are also available.

Analog camera _ TVI cameras

While you may wish to direct your procurement department to make future security camera purchases digital, it doesn’t mean you need to replace current analog security cameras. Solink can work with most IP and analog cameras, so there’s no need to upgrade your entire business security camera infrastructure to work with our platform.

TVI cameras

Transport video interface (TVI) is a way of transmitting analog video over a coaxial cable. It is one of several different technologies used to push analog cameras into high definition (HD).

The better definition is only the first of the two main goals accomplished by TVI. The other is the longer wired transmission range. Standard analog security cameras (sometimes called CVBS for composite video baseband signal) have a maximum wired transmission range of 300 ft. Some of these newer ones, including TVI, have ranges up to 900 ft.

This is a popular enough employee theft strategy that a security camera aimed at the dumpster and exit leading to the garbage area is recommended in Solink’s camera placement floor plan.

Bullet cameras

Bullet cameras are some of the most common business security cameras on the market. They are small and get their name from their shape. It’s also why they are sometimes called “lipstick cameras.”

Their small size and easy installation make them particularly versatile. You can find them indoors and outdoors, and they are usually less noticeable than larger security cameras (e.g., the turret security cameras discussed next). However, their shape makes them less robust to vandalism than dome cameras (see below).

restaurant security cameras_bullet camera

Some bullet cameras have varifocal lenses, allowing one to adjust the field of view of the camera without losing picture quality. However, you will need to make any adjustment on the camera manually.

Turret cameras

Turret security cameras have a ball-and-socket design. Within the “turret”, the ball-like camera can be positioned to look at different angles. This makes their installation and re-positioning flexible. However, once installed, you’ll need to physically reposition the camera to get a new field of view.

restaurant security cameras_turret camera

IP cameras

Internet protocol cameras (IP cameras) are controlled using an IP network and transmit data digitally. By using the IP networking standards, some IP cameras can work without needing any local storage. However, regulations may require you to keep storage on premise regardless. Furthermore, Internet bandwidth is not always perfectly stable, so having cloud and/or on premise storage is considered a more reliable system.

IP cameras can connect to a network in two main ways: WiFi or a power over Ethernet (PoE) cable. PoE cables provide both power and network access for transmission and reception. If WiFi is chosen, then the cameras will still need to be powered, either using a battery or being plugged in through an adapter. WiFi cameras can also be less reliable as video feeds may be temporarily unavailable when the connection is spotty or because of interference.

Dome cameras

Dome cameras are cameras covered with a dome. This obscures the direction they are facing, which can make employees and customers less sure what is or is not in the camera’s field of view. Their shape and the dome protection make them more resistant to vandalism.

However, as with many of the other cameras on this list, it has a fixed viewing angle that cannot be changed remotely.

restaurant security cameras_dome camera

Wireless cameras

Wireless business security cameras transmit the video feed wirelessly. They still require power. Although there are battery- or solar-powered security cameras, they tend to only be used where electricity is impractical.

Both digital and analog commercial security cameras can be wireless.

Wireless analog cameras

Wireless analog cameras connect to the network using an RF signal. Note that RF signals are less reliable than WiFi because cell phones and other nearby devices can interfere with the signal.

Wireless digital cameras

Wireless digital (IP) cameras connect to the network via WiFi. These signals are very robust to noise but have a more limited range, so wireless digital cameras can be considered more reliable than analog ones.

PTZ cameras

PTZ stands for pan, tilt, zoom, and that’s basically what they can do. PTZ security cameras can be controlled remotely to pan across a larger area or zoom in on something in particular.

This added functionality usually comes with a higher price tag. However, you might be able to offset the added cost per camera by using fewer cameras in total. Remember, though, PTZ cameras are only recording what the lens is facing. Additionally, the PTZ feature is mechanical, which is often a weak point in these cameras.

360 degree cameras (fisheye cameras)

Fisheye cameras can be considered the next step in the evolution of business security cameras. PTZ cameras improve on the base turret cameras by allowing the user to change the viewing angle remotely. Fisheye cameras go even further by giving the user a complete 360° by 180° view all of the time.

360 degree cameras get their nickname of fisheye cameras due to the distorted image shown.

However, using modern gaming technology, Solink stretches out this view to give you an immersive look at what is happening at your site. Here’s the 360 camera at work with Solink:

restaurant security cameras_360 camera
360-camera-solink-view

While the PTZ camera requires a loss prevention guard to be on duty watching the camera feed to change the view angle, 360 degree cameras show and record everything all the time. We’ve found that a single 360 degree security camera can replace four to six traditional security cameras in wide open areas.

Business security camera comparisons

Business security camera systems are complex. There are a lot of decisions to be made on the components. Here’s a list of common comparison points.

WiFi vs. Ethernet

The first thing to remember when comparing WiFi vs. ethernet is that this only means a camera is wireless vs. wired for data transmission. WiFi cameras still require energy to work, and that energy usually comes from being plugged into a socket.

However, PoE (power over Ethernet) provides energy and transmission in a single Cat 5 Ethernet cable. That means that WiFi and PoE security cameras are both still going to have one wired connection.

While WiFi is generally considered robust to noise, it is never going to be as fast, robust, or secure as Ethernet. Furthermore, WiFi has a limited range: usually about 50 feet before the signal becomes too weak for reliable video transmission; depending on the number and types of obstacles between the router and cameras, this distance can be reduced. Ethernet cables, used for IP cameras, can reliably be used at distances over 300 feet.

DVR vs. NVR

DVR and NVR systems are complex, and whichever you choose, it is likely the main backbone of your business security camera system. For that reason, we dedicate a whole article to DVR vs. NVR systems.

DVR and NVR find their distinction in how they receive video data. DVRs receive raw data captured from analog cameras. The signal is processed on the DVR before being recorded.

Conversely, NVRs do not process the signal they receive. The video signal is processed by the camera before being sent to the NVR.

Local storage vs. cloud storage

The choice of local storage vs. cloud storage is often answered with “both.” In that case, you’d have local storage with cloud backup storage. This represents an especially secure security system, with data unlikely to be lost in any circumstance.

Local storage can generally be broken down into using an NVR/DVR appliance or built in camera storage.

Cloud-based storage requires a continuous, reliable Internet connection. This is not always feasible. However, the benefit of having data in the cloud is that you can access your video anywhere. Indeed, Solink provides both local storage and cloud access to the platform.

SD vs. HD vs. 4K

Standard definition (SD), high definition (HD), and 4K refer to the resolution at which your business security cameras record footage. Classical analog cameras record in SD, but there are some HD analog security cameras on the market. Conversely, IP cameras have at least HD and sometimes even 4K resolution.

Resolution at its core is how many pixels are recorded in an image. Here’s a summary of the different resolutions:

  • SD usually refers to resolutions below 720×480 pixels
  • HD usually refers to 1280 x 720 or 1920 x 1080 pixels.
  • 4K refers to 3840 x 2160 to 4096 x 2160 pixels.

Pixels are little color dots, and more of them mean the dots are closer together and therefore you can see more details. This might lead you to believe that higher resolution is always better. However, there are several other considerations that should be included in your decision-making process.

Bandwidth

Bandwidth is basically the speed of your Internet. Higher video resolution requires more bandwidth to transmit. Here’s a chart showing the recommended bandwidth levels for different video resolutions:

Video resolution Average bandwidth use for simultaneous viewing (at 10 fps) *
720 x 480 0.75 Mbps per camera
1280 x 720 1.5 Mbps per camera
1920 x 1080 2 Mbps per camera
3840 x 2160 8 Mbps per camera
4096 x 2160 10 Mbps per camera

Note that the number of frames per second of your video has a high impact on the requirements. However, modern encoding systems make the total resolution a much bigger factor in required bandwidth than frames per second.

If you have multiple cameras streaming to the cloud, the amount of bandwidth required for 4K adds up quickly. This is the major reason that Solink simultaneously records multiple resolution streams at once and stores the data locally.

That way you can see the SD stream instantly, the HD one with a short buffering delay. Furthermore, you don’t need to send all of your security camera feeds to the cloud at once.

However, you still have access to all of your video remotely, and Solink can easily accommodate higher resolutions. The dual feed is a really nice quality–function tradeoff. In fact, there is no tradeoff as you get both fast-loading SD and better-quality HD.

Field of view

A camera’s field of view is the angle width (and height) that it is recording. Business security cameras have a wide range of fields of view. They can be as low as 40° for zoomed-in smaller cameras and go up to 360° by 180° for a 360 degree commercial security camera.

The FOV/resolution combination of your cameras dictates the final quality of the video. With the same resolution, a lower field of view will show more details than a larger angle. For this reason, 360 cameras usually have a much higher resolution than other regular cameras

Plug-in cameras vs. battery-powered cameras

Battery-powered security cameras absolutely exist. However, their use cases are generally reserved for areas without local electricity connections. In areas where a security camera can be plugged in and/or where continuous 24/7 video recording is required, charging the battery regularly would cause more trouble than any time saved installing a power cord (or PoE connection).

Battery-powered security cameras that only function when triggered, for example by a motion sensor, can last several months on a single charge depending on the level of motion happening in their field of view, so in remote locations with lower security needs they could be useful, but in most situations they are not recommended.

IP camera vs. analog cameras

IP security cameras send digital video over Ethernet or WiFi connections, whereas analog cameras send analog video over a coaxial cable. This is the major difference between them, but there are more.

Resolution

Analog security cameras tend to be SD or HD (e.g., TVI security cameras), whereas IP security cameras are at least HD and are also available in very high resolution.

Video analytics

Solink can provide VSaaS solutions to companies using both analog and IP security cameras. IP security cameras can provide richer data, but analog cameras are not yet completely obsolete. Working with your existing business security camera system infrastructure is a major benefit of Solink as it lowers your startup costs.

Power over Ethernet (PoE)

PoE eliminates the need for separate power and data cabling. This is a major benefit of IP security cameras over analog ones.

System cost

IP security cameras are on average more expensive than analog ones. In addition, IP cameras are easier and cheaper to install since they only need an Ethernet cable where analog cameras require a power supply cable and a coaxial cable for the signal. These features combined mean that, when buying a new business security camera system, purchasing IP security cameras is generally comparable to or even cheaper than buying an analog security camera system and also future proofing your system for upcoming improvements.

What should you consider before purchasing a business security camera system?

There are many decisions that need to be made when building or expanding your business security camera system. Let’s look at some of the major ones.

Installation and camera sourcing

Many companies will force their customers to purchase a whole new set of security cameras to integrate with their data analytics platform. This is not the case with Solink. We want to have a low startup cost and no contracts.

We want customers to stick with us because we exceed your expectations and not because you’ve been forced into a long contract with a massive sunk cost buying proprietary cameras.

While we can help you procure any type of security camera at a great price and have them installed, we are also compatible with your existing cameras. Furthermore, you are free to source your own cameras, as well as do any installation yourself or use a trusted local installer.

That freedom guarantees savings.

Type of camera

First, you need to decide between analog and IP security cameras. For new purchases, IP cameras are the better option. Next, you’ll need to consider the different types of security cameras and their coverage. Finally, some cameras are only recommended for indoor installation, while others can be placed indoors or outdoors.

There’s a great example coming up that shows you where to place each camera and why a little bit later in this article. This camera placement use case is for a quick serve restaurant (QSR), but the principles are the same for other retail locations.

Type of storage

Analog cameras use a DVR, IP cameras use an NVR, and there are hybrid solutions as well. Furthermore, these solutions are on premises, whereas cloud storage is also an option. The recorder is usually the most expensive part of the system.

Generally, bandwidth will become an issue if you stream footage directly to the cloud, but having a cloud backup of your data is an added level of protection. Remember, cloud access to Solink’s platform and real-time remote video monitoring are possible regardless of where your video is stored.

Amount of storage

Do you want 30, 60, or 90 days of video retention? Do you need 4K or is HD sufficient? These questions will help you decide on the size of appliance you need for local video storage. Solink can provide solutions no matter the answer.

Features

The video analytics platform provided by Solink is loaded with features, and more features are coming out with each automatic update. If you haven’t looked at our feature page yet, please take a look at everything Solink has to offer.

Why do you need video analytics as part of a business security system?

Business security cameras can be a big investment. They also provide some of the richest data you can find. Simply put, if you aren’t using a video analytics platform to search, sort, and see that data, then you aren’t getting the most out of your investment—and you aren’t getting all the information you need to make the best possible decisions.

While loss prevention, reduced shrinkage, and improved security for your customers, visitors, and employees are obvious benefits, there are less obvious ones too. You’ve probably built your commercial security camera system around these benefits, but some of the biggest cost reductions are from reduced liability.

Monitoring your premise with remote video surveillance allows you to make sure that company policies and regulatory requirements are being met. Here are just two examples:

  • Your company policy states that all wet spots need to be mopped up and a wet floor sign be placed. The weather report says rain across the northeast. Solink shows you all the cameras facing front doors at all your locations so you can confirm that wet floor signs are being used. This reduces your liability under potential slip-and-falls. In fact, Veterans of America-Michigan uses Solink to do just that.
  • The labor shortage is making it harder to hire and retain employees. Reduced hours means that some locations are cutting corners. Stockrooms are not being kept as clean as they should be, which has led to some emergency exits being blocked by merchandise. You’ve received some Occupational Safety and Health Administration (OSHA) fines recently and are looking for an efficient way to monitor all of your locations. Solink shows you a folder with all cameras pointing at the emergency exits of your locations so you can scroll through hundreds of sites in minutes every day to confirm those doors are being kept clear.

What should you consider when choosing a business security camera?

The following are some of the main features to consider when choosing your security cameras:

  • Resolution: The resolution of a camera indicates how much detail will be recorded. If you are filming in close range on a small area, then low resolution shouldn’t be a concern. However, higher resolutions are usually recommended for modern video surveillance.
  • Frame rate: The frame rate is the number of frames per second that your camera records. Having a low frame rate (e.g., 5) will severely diminish your ability to track people across your facilities. In addition, depending on the industry in which you operate, you may be required to record with a minimum frame rate. Traditionally surveillance systems record at 10 frames per second, as it is a good balance between lower storage needs and good quality.
  • Camera type: Different cameras are best suited for different environments. A bullet or turret camera can record a smaller area than a 360 degree security camera. So the former is best used to monitor a hallway or entrance, while the latter is better suited for monitoring an open area, such as a dining hall or a department store section.
  • Indoor/outdoor: Generally speaking, all security cameras can work indoors, but not all security cameras are appropriate outdoors. If you need both indoor and outdoor video surveillance, then you should make sure any cameras placed outdoors or in harsh environments such as freezers are able to function in your local climate.
  • Lighting: Some cameras are designed to operate in the dark. If this is important for you, then consider buying cameras with IR capabilities.
  • Audio: Not all business security cameras record audio. If this is something you might need, then be sure to choose cameras that also record audio.

Where should you place your security cameras?

Placing the cameras in your facilities is a key step in building a strong business security system. We’ve discussed some of the issues you need to keep in mind when doing this in a restaurant previously, but now we share with you a complete business security camera floor plan.

Take a look at the commercial security camera floor plan below. Note that, if you click on it, you can see a much higher resolution version.

Solink-QSR-restaurant-floorplan-camera-placement-with-chart-scaled-1
This plan is for demonstration purposes only, and all sites have unique security requirements.

The following table summarizes the camera type, location, and reason for the coverage. The full reasoning behind this business security camera floor plan can be found here.

Outdoor cameras
Number Camera Type Location Purpose
1 Turret or bullet Drive thru Monitor drive thru speed of service
2 Turret or bullet Walkway/parking lot Monitor slip-and-falls and traffic
3 Turret or bullet Walkway/parking lot Monitor slip-and-falls and traffic
4 Turret or bullet Patio Protect patrons
5 Turret or bullet Backdoor/garbage Perimeter defense
6 Turret or bullet Drive thru Monitor drive thru speed of service
Indoor cameras
Number Camera Type Location Purpose
7 360 Lobby Protect patrons
8 Dome Dining area Protect patrons
9 Dome Dining area Protect patrons
10 Dome Takeout counter Monitor delivery services
11 Dome POS Monitor transactions and cash activity
12 Dome Cook line Monitor food safety
13 360 Food prep area Monitor food safety
14 Dome Freezer Inventory surveillance
15 Dome Freezer Inventory surveillance
16 Dome Office Safe security
17 Dome Storage room Inventory surveillance
18 Dome Office entrance/backdoor Safe security and perimeter defense

While a single reason for the placement of each camera is listed in the table, the truth is that all of these cameras are performing multiple functions. Please view the complete report to see just how much value beyond security that your surveillance cameras could be providing. Notice that turret or bullet cameras are used outdoors because they are designed to endure harsh environments. Indoors, a combination of dome and 360 degree cameras are used. The domes provide a similar field of view to turrets or bullets, but the direction the camera is facing is hidden, which adds a bit more security value. The 360 degree cameras are placed in the most open areas to monitor the whole lobby and kitchen.
