Using Visual Verification to Defend Against Perimeter Fence Intrusions

Problem

A used car lot owner had re-occuring issues with intruders cutting holes in the perimeter fence during night-time hours and vandalising or burglarising the area. The intruders would not enter the small office building, so the security system was never triggered. The customer did own a video surveillance system and it would record criminal activity but it did not prevent or deter crime.

Design

Using the existing intrusion alarm panel and the existing video system, the systems integrator introduced two OPTEX CKB-304 Visual Verification Bridges and four OPTEX Redwall SIP-3020 Outdoor PIR motion detectors. The motion detectors were installed over the two main perimeter light poles pointing into the lot with IP cameras located directly above each of the motion detectors.

Application

With the two CKB-304 Bridges installed, the integrator can provide the monitoring station immediate access to eight live cameras during every alarm event. The Redwall SIP-3020 provided up to 30m of distance coverage and 20m width, complete with anti-masking and vandal tampers. With this simple but effective solution, the integrator was able to provide their customer with immediate visual verification of alarm sensors, only when the alarm panel is armed. Wireless key fobs were provided so the dealer can arm and disarm the system from outside the gate helping to eliminate false alarms during arming and disarming.

Solution

Since the completion of this installation, there have been several nuisance alarms caused by cats that were immediately disregarded. Due to the visual verification solution there was an apprehension and the client has not had any vandalism or crime since. Per the customer’s request, the OPTEX Bridge has been installed on three additional car lots.
