Wireless home alarms are the most popular home security devices because they are reliable and they are inexpensive. This Motion Detector Alarm is a good example.
It has a passive infrared system that detects motion in any selected area. Once motion is detected a 105 dB alarm sounds. For business owners, you can use it to announce customers in your store while you’re not out front. Or you can use it to protect a secure area in your store-a two-tone chime sounds instead of the alarm. The alarm can be programmed to sound for 30, 60 or 90 seconds, depending on your setting. There is also a program re-entry delay that can be utilized to allow you time to disarm the system once you enter your home or business. It has a programmable security code and a panic button for immediate sound.
It works up to 40 feet away and protects a 110° radius.
