Current slide {CURRENT_SLIDE} of {TOTAL_SLIDES}- Best Selling in Sensors & Motion Detectors
The 433 Mhz. Door-Window transmitter is the greatest range transmitter on the market today. I have designed, installed, and repaired security systems for nearly 40 years, and the old style transmitters or "Wireless" alarms in the past were always subject to false alarms. Today, with the encrypted digital signal, you can say GOOD BY to false alarms forever, and with the installation ease of these High Range transmitters, coverage throughout the protected area is NO longer a problem. The property owner can install their own alarm, saving hundreds of dollars from hired labor. The early wireless transmitters sold for $50-$80 a piece! The old style transmitters only had a 10 meter range. This New style transmitter has nearly a 50 meter range and a much higher frequency that cam penetrate walls much easier!Read full review
