Movement Sensors

The surveillance systems described above are generally triggered by our specially designed movement sensors. We offer two versions: the Active Infra-red Pair, which sets up a narrow accurate beam, or our Passive Infra-red Sensor, which senses a "volume" of space. The former is far more suited to the intelligent sensor filtering functions found in our surveillance systems; while the latter, though less versatile, offers greater ease of deployment in certain situations.

Setting up of either type is simplified by our flexible attachment and adjustment system. Optional stainless steel braiding protects against rodent attack for cabled versions. Alternatively, the sensors can be ordered with radio links. In this case, the sensors require their own battery pack.
