If you can a hang a picture on the wall, there is a good chance that you can install a wireless security
system yourself. Going wireless means that there are no wires to run except for the electrical plug that will power the control interface. Typically, you only need to be able to screw some cameras or sensors, or in some instances just stick them to the wall via tape
adhesion. That means you don’t have to break, drill, fish, or run wires through your wall, and you could connect to your control box without having costly electrical installations. The larger the house, the bigger is the savings when it comes to wireless configurations. However, if your home is too large, you might need to go for hard wired to be able to have a more reliable security system.
