You can save hundreds of dollars by going wireless. Most of the DIY systems today are wireless configurations. As mentioned
before, it will also save you a lot of time in the process. 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. In general, a 2GHz system can keep constant connection with wireless components in about an acre worth of residential area. One disadvantage of the wireless system is that the components will eventually run out of battery life.
