To install CCTV outside of the house, consider which areas you want covered and that’ll help you decide how many cameras you need. You’ll then need to decide between a wired or wireless setup. Keep in mind that if you opt for wireless, the cameras will need to be easily accessible so you can recharge the batteries. While a wired set up may require professional installation, you won’t have to worry about connection issues or recharging. Once you’ve got all your cameras, mark the exact place you’d like to install each one, attach to the walls securely and link them to an app or with a computer system.
