How Many Security Cameras Do I Need?

Security cameras are essential tools to monitor smart homes and keep them safe. These days, monitoring technology has improved by heaps, which allows more freedom and flexibility while setting up cameras.

However, a chief question that often arises in users’ minds is how many of them they need. There are multiple combinations to choose from, and none have any significant upper hand over the other. Thus, the answer lies hidden in the respective user’s home layout and requirements.

Of course, one can hire a professional and ask them to configure the security cameras in the best possible way. But, it is worth noting that such technicians charge a premium for their service. In addition, it takes away the fun do-it-yourself (DIY) part of setting up a smart home.

Thus, in this guide, we will help users choose the best camera combination to help them figure out what is best for their home with ease.

A guide to choosing the best security camera combination for homes

While choosing CCTV camera combinations, one should consider multiple factors. The most important of them are listed below.

1) Figure out how large the building is

Calculating the size of the building is a significant step while configuring smart homes. A small 2 BHK apartment may not require more than two cameras, but a two-storied mansion may need as many as twenty or more.

However, it is worth noting that a formula that states how many cameras one should install per 1,000 square feet does not exist. The building size only serves as a rough idea of what to expect.

2) Work with the building layout in mind

Once users have calculated the building size, it is time to draw out the layout of the building. It will immensely impact where users will place the cameras and how many of them one needs.

A simple rectangular building or an apartment may not require a ton of cameras. However, a building with arches, curves, and numerous corners might require more surveillance equipment.

3) Focus more on the corners of the building that require more security cameras than others

It is crucial to figure out which corners of the building require added security and double down in those locations.

For instance, one should install at least one security camera at every entrance to the building. The garage and parking spots are other important locations that need added security.

The terrace will not require robust surveillance. Thus, a single camera with the entire region under its field of view (FOV) might serve the purpose.

4) Capabilities of the particular CCTV model one is looking at

The capabilities of the particular security camera one has in mind will impact the decision.

One can opt for rotating cameras that will slash the number required significantly. Static cameras will require more units to cover the whole area effectively.

Thus, users should choose the particular security camera they like the most.

5) Total money users are willing to spend on surveillance cameras

Doubling down the number of cameras can exponentially increase the total expenditure. Thus, users must work with their budget in mind.

After figuring out which CCTV one needs and the total budget, calculate the maximum number of cameras. If the budget allows, get this many cameras to secure the home. Some extra surveillance will never hurt anybody.

However, those with a tight budget should check the building layout to ensure the whole building has coverage. It will help users to find the minimum number of cameras they need.

Some extra points to consider

While building a security camera system for a typical American home, one can consider the general national average to get some insight.

Most users require at least two HD surveillance cameras to monitor the most significant locations. One can not spend any further and call it a day.

However, those looking to wrap up their homes with more surveillance can go up to the national average of six security cameras per household.

A possible camera combination is as follows:

  1. One HD camera for the front porch.
  2. One HD camera for the garage.
  3. One HD/standard CCTV for the rear door.
  4. One HD/standard CCTV for the backyard.
  5. Two CCTVs to monitor the sides of the house.

However, the above combination can vary widely depending on the number of doors and vulnerable spots like breakable windows. One can also want to place surveillance equipment indoors, which increases the camera count significantly.

Tips to intelligently reduce the number of cameras

If the number of cameras required to monitor a home exceeds your budget, do not panic. There are several ways to cut down on surveillance equipment without sacrificing security.

Try multi-tasking with the cameras. Figure out spots where one camera can serve the purpose of two or more. For instance, one strategically placed camera can monitor the garage door, front porch, and driveway.

Depending on the house layout, try to find more such positions. A good idea would be to invest in rotating cameras.


Users should get as many cameras as required. This will ensure the security cameras monitor the house effectively. However, consult a professional for the best combination possible if the process gets confusing.
