How Many Security Cameras Do I Need?

Business owner of this office wonders, "how many security cameras do I need"

More and more organizations are opting for security systems that include advanced, modern-day security cameras. But, many wonder, “how many security cameras do I need?”. Well, when it comes to outfitting your organization with security cameras, there is no one-size-fits-all answer. The number of cameras you need will vary depending on the size and layout of your organization’s building, as well as your specific security needs.

With that said, there are a few general guidelines you can follow to help you determine how many security cameras you need for your organization. In this article, we’ll cover the factors that affect how many security cameras you need as well as the steps to take to determine how many cameras to implement in your organization.

How Many Security Cameras Do I Need: Influencing Factors

Large buildings, like pictured, need more security cameras than smaller ones

The number of security cameras an organization needs depends on several factors, including the size and layout of the premises, the level of security required, the amount of foot traffic, the location of the organization, and the budget. Larger businesses or those with complex layouts may need more cameras to cover all areas, while businesses with fewer staff or less valuable stock may need fewer cameras. Moreover, those organizations that have more foot traffic, like schools, may need less than those that do not bring in to many outsiders. The type of organization or business also affects the number of cameras needed – for example, a bank or hospital will require more security than a retail store.

Overall, the following factors will affect how many security cameras you need: size and layout; desired level of security; foot traffic; location; budget; and type of organization. By taking all of these into account, you can ensure that you have the right number of cameras for your organization. We’ll now turn to the steps to take to determine how many security cameras you need.

How Many Security Cameras Do I Need: The Steps to Take

When it comes to your organization’s security, one of the first questions you’ll need to answer is: how many security cameras do I need? This can be a tricky question, as there are a number of factors to consider. But with a little careful planning, you can determine the right number of cameras for your organization. Here are a few steps to take.

How Many Security Cameras Do I Need: (1) Determine Your Budget
Man budgeting to figure out how many security cameras he needs

The first step in deciding how many security cameras you need is determining your budget. How much money do you want to spend on your security camera system? Write this number down. This will help you determine what kind of system to install.

Now, forget about that figure for a moment. It may seem illogical, but the following question is unrelated to your current financial situation.

How Many Security Cameras Do I Need: (2) Evaluate Your Organization’s Need

The next step is to evaluate your needs for security. To do this, compile a list of all the areas you want your video surveillance system to cover. Disregard your budget at this point – just write down where you’d like to place cameras.

For example, many organizations have cameras at the following locations: primary entrance, secondary entrances/exits, parking garages or lots, lobbies and other common spaces, employee-only zones, cash registers, and high-traffic hallways. It may also help to take the following questions into account. What are your specific security concerns? Are there sensitive areas that need extra protection? How many people are in your organization? How large is your facility? What kind of activities do you have going on within your organization?

Now add up all of the items on your list. You now have an idea of the maximum number of cameras you’ll require. The focus is on the phrase “maximum”. This figure is most likely not the exact number of security cameras required. In the following step, we’ll show you how to lower that number as much as possible.

How Many Security Cameras Do I Need: (3) Consolidate

The third step is to determine where and how you’ll place the cameras. This will help you reduce the previous figure you came up with in the last step. In the last step, you most likely listed a few places that are close to each other on your list. Now, you’ll consider how you can cover those various surveillance areas with a single camera. Perhaps you can cover a large, 360° area with a PTZ or a fisheye lens camera. Alternately, you might be able to place cameras such that they can monitor several different areas or rooms.

So, in this step, you’ll examine each of your ideal regions and see if you can limit them to as few cameras as feasible. Begin at the top of your list and number each region. Use a new number when you get to an area that requires a whole different camera. Take a look at the following example of a small business for guidance:

  • 1 front entry,
  • 1 parking lot,
  • 2 back entry/exit,
  • 3 shopping space
  • 3 cash register

So instead of having a camera for each location, which would result in 5 cameras, you can use specific types of cameras with a large, rotating field of view (e.g., fisheye camera) to surveil different areas at once (e.g., one camera for both the front entry and the parking lot). Doing this would result in having 3 cameras instead of 5.

The number at the end of your list is the ultimate number of security cameras you require. Now that you have that figure, we’ll return to the budget.

How Many Security Cameras Do I Need: (4) Budget
Budget is important in deciding, "how many security cameras do I need"

You should now have two numbers: budget and the final number of cameras you require. In some circumstances, the budget you set aside may be sufficient to acquire each camera in your system. Yet, it is frequently too tiny. However, that’s manageable because you now have a strategy. You can prioritize the cameras that are most important and then save up for the rest of the cameras. This can be done because the mere presence of cameras is often enough to deter crime. So, in the long run, this is better than buying a small amount of cameras and sticking to it.

Continuous Security Monitoring
24/7 monitoring is available despite the number of cameras you may have

Remote security monitoring is a process that allows security professionals to keep an eye on your property and assets from afar 24 hours a day, seven days a week. There are many benefits of using remote security monitoring for your organization including deterring crime, catching criminals in the act, providing evidence for criminal prosecution, and peace of mind. Additionally, since someone will remain surveilling your location, you won’t have to worry too much about how long do security cameras keep footage.

  • Deter Theft, Vandalism, and Crime: Security systems with remote security monitoring can be an effective deterrent to criminals. If potential criminals are aware that their activities are being actively monitored, their likelihood of committing a crime decreases.
  • Identify Criminals in Real-time: Security systems with remote security monitoring can also help catch criminals in the act. This type of system provides a proactive approach to security by alerting security personnel to potential risks as they are happening, rather than after the fact.
  • Provide Evidence: Remote security monitoring can also provide evidence for prosecution in the event of a crime. This ensures that criminals are apprehended and prosecuted, and it may protect your company or organization from a repeat offense.
  • Peace of Mind: Remote security monitoring can provide peace of mind for business owners. Knowing that your property has round-the-clock protection in the event of an emergency can help reduce anxiety and stress levels.

The Steps in Remote Security Monitoring

Not all security systems include a remote monitoring component. Consequently, it is essential to actively seek out security systems that provide around-the-clock monitoring by trained security personnel. With the Alarm license and security cameras from Verkada, you can rest assured that your business, facility, or organization is continuously and remotely monitored for security threats. So, how does Verkada’s remote security monitoring function?

Step 1 of security monitoring is detecting unusual behavior

First, you choose which cameras you’d like monitored and when. Then, Verkada’s sophisticated AI analytics notify our round-the-clock monitoring agents whenever a human is detected in the scene. Other Verkada devices, such as access control or intrusion sensors, can also generate alarms for review.

Step 2 of remote security monitoring to review events - surveillance feature is available no matter the number of cameras

Second, as soon as an alarm is triggered, monitoring personnel will examine the associated video footage to determine if anyone or anything is in imminent danger. Finally, the monitoring agent will immediately get in touch with the customer’s call list if there is a real threat. Customers can also request that representatives call emergency services on their behalf. By dismissing the incident if there is no immediate danger, the agent reduces the likelihood of false alarms.

Step 3 of security monitoring is taking action

Essentially, the Verkada agents that run your building’s remote security monitoring (1) identify strange activity, (2) examine the situation, and (3) take initiative if there is an emergency at hand. 

Advanced Security with Verkada 

Overall, Verkada offers a remote security monitoring feature that provides unlimited event-based monitoring for real-time threat detection and response. You can feel at ease once you secure your location(s) with round-the-clock expert monitoring.
