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. It is therefore necessary to invest
in a dependable battery backup system not only in case of emptying battery life but also to continue to protect your
home even in the event of a power outage or a break in attempt by an intruder. Also, note that it is better to buy equipment that is powered by rechargeable batteries. They may have a larger upfront cost, but will prove to be more economical in the long run. Look for a system that notifies you or gives an alarm that can alert you if which batteries are running low.
