The MotionProtect Outoor Hood from Ajax Systems is an accessory for the Motion Protect Outdoor Outdoor that has been designed to eliminate false alarms when the device is exposed to the harshest weather conditions. Although the MotionProtect Outdoors anti-masking sensors react to spray paint, extreme snow or thunderstorms may result in disturbance. Installation is easy, there's also no need to dismount the MotionProtect Outdoor when installing the hood, simply attach the item to the top of the device.
