A wireless device is merely a sensor like a door contact or motion detector that communicates wirelessly between the control panel and the sensor. Not to be confused with cellular communications that transmit signals between the control panel and our remote monitoring station. A wireless device takes very little time or experience to install, is battery operated, and initially is less expensive, but over time could cost you.
A cellular communicator can be used on a wireless or hardwired system. Cellular is actually the name for one certain type of wireless communication network or path that allows a dedicated communication line set aside for security system purposes. It takes a professional with experience to run wires and hardwired systems are preferred because they are more stable and less prone to service issues.
In larger homes, a wireless system may not be the best choice. Since the sensors are battery operated, most have an open air range of about 100 feet line of sight. In larger homes, devices cannot be seen by the control panel because the device is too far away and will cause annoying false alarms and trouble signals. With so many doors and windows to protect, changing batteries becomes a chore and, additionally, if you are planning to integrate your alarm with smoke detectors you must also hardwire the devices to meet building codes!
It is our opinion that the best system would have a cellular communicator and hardwired sensors in your house to your control panel. A lot of companies only offer the installation of wireless sensors because they are easier to install, but in a larger home, we recommend and offer a full hard-wired and cellular setup as your best and most secure option for your family. If you have a wireless security system and would like to upgrade we would be happy to help you or advise you what might be best for your particular situation.
