The Motion Detector Damage Stopper® helps protect PIR detectors against vandalism or accidental damage. For wall mounting application, this tough wire cage is constructed of 9-gauge steel wire with corrosion-resistant polyester coating. The wire guard does not interfere with the effective range of any protected motion detector. Extremely effective in reducing malfunctions and high maintenance costs, the wire guard is highly recommended for areas where abuse to PIR detectors is severe. Installation and servicing are easy. As all STI protective covers, the Motion Detector Damage Stopper® is backed by a three year guarantee against breakage in normal use.
