Security Sensors

Security sensors come in two basic types. Motion sensors detect any movement in an area that is secure, and trip sensors monitor points of entry such as doors and windows. Each of these can be connected to a larger security system that will sound alarms and call police. Most homes would do well to have trip models at all points of entry, while offices would benefit most from having motion units in the interior of the building. Depending upon your needs you can decide whats best for your circumstance.
