How many security cameras do I need? It’s a question we’ll all ask ourselves, increasing home security and protecting the things that matter to us most.

Despite this, there is no magic number. How many security you need depends on numerous factors, including the size of your home, what coverage you need, how many entry points you have, outbuildings, and more.

There is no one-size-fits-all approach. But we can provide you with a basic guide to set up your home security.

So, this blog post is exactly that – a guide on how many security cameras you need for your home.

How many outdoor cameras do I need?

To find the exact number of cameras you need, we first need to analyze the entry points of your home.

Ideally, you should have at least one camera covering each entry point.

The average home has five entry points:

  1. The front door
  2. Backdoor (and side doors)
  3. Ground floor windows 
  4. Sheds and garages
  5. Yards 

The front door

The front door is not only an entry point, but it’s also common for porch pirates to steal parcels.

Installing a security camera on your front door is a must – the presence of it is often enough to scare off trespassers.

If you’re looking for something a little less visible and more practical, you could invest in a video doorbell camera.

Backdoor (and side doors)

Alongside the front door, the backdoor (and any side doors) you have are next on the list.

These should have cameras covering each entry point – these can be in sight to send a warning to criminals.

Ground floor windows

Not all ground-floor windows require a security camera, but if they’re big enough to fit a person, then you’ll definitely want some coverage.

Ensure to lock all windows when you’re not home and when going to sleep – this is a common entry point aside from doors.

Sheds and garages

Sheds often house expensive goods with minimal protection, think: bikes, power tools, garden equipment, and other items.

Install an outdoor security camera above your shed/watching over your shed to prevent or at least catch the criminal in action.

The same applies to garages, especially if they’re attached to your home.

Often, garages can be a gateway into the home. And if not, well, it’s likely you have a vehicle or two in there, more expensive tools, and other goods. Install a camera here too. 


Finally, you should install an outdoor security camera in your yard. 

An extra set of eyes can help deter theft. And in the case of an incident, you’ll have footage to show the police.

How many indoor cameras do I need?

Okay, now that we’ve covered outdoors, how many security cameras do you need indoors?

Ultimately, this is down to personal preference. 

Outdoor cameras are often used to deter criminals, while indoor cameras can help recover stolen goods in the event of theft.

Also, indoor cameras can also point outside, providing additional protected coverage.

Furthermore, if you have young children or elderly parents living in the home, you can install cameras where needed (with permission, of course) to check in from time to time. This can provide peace of mind when you have a babysitter, for example. 

How many cameras do you need for home security?

So, exactly how many cameras do you need for home security?

We’d start by installing outdoor security cameras for each entry point around the exterior of your home.

Ensure to install cameras on sheds, outbuildings, and garages, and don’t be afraid to place these in plain sight. 

After these are installed, you can sprinkle a few indoor cameras facing outside, and if needed, indoor cameras as required.
