You’ve been thinking about getting a security camera for your home—maybe you even have the perfect model picked out—but can't decide which rooms need a camera. One thing's for certain: no need to rush out and stick a camera in every room. So how many security cameras do you need? Depending on your home, it might just be one.

1. For apartments and small homes

If you live in an apartment or smaller house, a simple doorbell camera might be all you need. It multitasks to watch your front stoop and keep any eye out for visitors and any packages dropped off.

2. For larger properties

If you have a larger property with outdoor structures, any side entrances, or rooms inside you want to watch, more cameras won't hurt. Any structures like sheds or garages that aren’t super visible from your home might benefit from having some extra eyes on them.

You can find outdoor cameras like the Ring Floodlight Cam that house an on-board motion sensor, floodlights, and a camera. So if anything triggers the sensors, you’ll get a clip of it.

And honestly, unless you have a ton of stuff to watch out for like a safe, your kids’ nursery or playroom, or a pool entrance, you probably don’t need more than two.

3. Focus on common areas

In most cases, it's not a good idea to put security cameras in private areas of your home such as bedrooms and bathrooms—a notable exception is using a baby monitor in nurseries where babies sleep.

Stick to common areas instead:

  • Entryways and hallways
  • Family rooms, living rooms, and offices
  • Kitchens and dining rooms
  • Yards and driveways

Small homes and apartments rarely have more than one common area, so a single camera works in most cases. Depending on the layout of your home or property, you can sometimes monitor multiple common areas at once with strategic camera placement, lenses with wide fields of view, or pan-tilt cameras, like the Reolink E1 Zoom.

Home examples

Every home is unique so there's no way to create an exhaustive list of where you might need a camera, but here are some examples of suitable places for a home security camera. When in doubt, consider cameras at entrances, in the largest rooms, and in vulnerable areas.

Multi-camera security systems

If you need more than four cameras, consider getting a multi-camera security system bundle instead of buying cameras separately. These systems are also great for local video storage on a DVR or NVR.


The good news is you don’t have to spend a ton of money or set up cameras at every access point like a bank or a business. Cameras at your entrances or outside structures should be enough to catch anything that you might not on your own.
