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. Or if you can, frequently test the components of your system and replace batteries regularly. Another disadvantage of a wireless configuration is the risk of faulty installation. Even though you don’t need any formal training to set up this system, there’s always the risk that you did not do it properly. When you hire a service provider, you can make sure that everything will be done correctly.
