The risks of a security incident can be reduced drastically by taking necessary precautions. According to an online home security expert (home improvement.com), alarm systems come in a variety of shapes and sizes nowadays - from very basic motion-activated alarms through fully monitored home security systems. In between lie a number of variations on a theme, including trip wires, motion sensors, closed circuit telemetry and more.
The truth about alarm systems is that more money doesn’t always ensure superior performance – in fact, above a certain threshold you may even see diminishing returns. Mike Challo, C.E.O and founder at Isys technologies limited states that one of the hottest new varieties of home security system is the wireless kind. “These simple systems rely on radio signals to keep everything connected,” he said, adding that the advantage is that you save tremendous amount of time and money on the installation.

The wireless receiving distance in an open place is 250m, indoor: 30~50m, (depending on the surrounding environment and wireless interference with a standby current of 15mA.

3.    32 zone wireless burglar alarm system

This system has a wireless frequency of 433MHz or 315MHz. An adaptor in inbuilt which inputs electricity from a 110 ACV ~240 AC. The wireless receiving distance in open place is >200m, indoor and 30~50m outdoors, depending on the surrounding environment and wireless interference. The internal volume is 95dB with an external siren of 110~120 dB.

This system can protect 32 zones with 32 different zones indicated on panel. The zones have different number of sensors according to priority, and they can be partially disarmed by remote control.
