Once you know how many cameras you need, you'll need to think about what specific cameras you want. A home surveillance system can cost anywhere from a few hundred dollars to well over a thousand, so make sure you consider the type of cameras you need before buying -- the features below should be clearly labeled on the box. While you can buy all of the parts separately, buying a full 'surveillance set' is usually cheaper and easier to install.
- Wireless vs. Wired: Wireless cameras are easy to set-up without drilling or running cables through your house, but the quality can be sub-par the further they get away from the receiver. If you are covering a big area, go wired, but most houses find wireless an easier set-up process.
- Indoor or Outdoor: Cameras that are not made to be placed outside will quickly break when exposed to rain and humidity, so be sure to choose accordingly.
- Motion Sensing: Some cameras will only record when they notice motion, saving lots of space and energy while only capturing footage when someone is in the room.
- Remote Viewing: Many high-end cameras offer the ability to stream their footage to your phone or laptop anywhere in the world, making it possible to check out your house through a provided program or app.[2]
