Wireless Systems: Disadvantages

Installers and homeowners alike will tell you that wireless systems are a lot more prone to false alarms. The time for the batteries to be replaced comes around pretty quickly and because no wiring is necessary, neither is an NIC qualified engineer, meaning the quality of work could suffer greatly.

Wireless systems use radio frequencies, and these can sometimes suffer from interference (RFI). If you are concerned about cost, the price of installing and keeping a wireless system could put you off. The components are generally two or three times more expensive than those of a hard-wired system. They also lack in reliability.

"Wireless systems cannot achieve a security grading above 2, which means they are nowhere near as secure as wired systems. However, this is sometimes suitable for domestic properties."

Industry professionals also doubt the reliability of cheap/imported wireless kits, as the communication between the control panel and the detector isn’t always two-way. Wireless systems are also easier to disable than wired systems, which has to be taken into consideration when choosing how much security you want.
