Rokonet iWise/Cosmos Pet DT Detector
Highly immune to household pets and rodents.

The iWise/Cosmos Pet DT has been specially designed to be immune to household pets (45 kg dogs, up to 6 cats and multiple rodents).

Using unique VPT algorithms (Variable Pet Thresh-holding) and a custom designed lens, the iWise/Cosmos Pet DT can readily distinguish between intruder and pet signals, while assuring superior catch performance.

The lens has been designed to reduce signals from pets, while assuring catch performance of intruders. It has 7 zone pairs in each of 3 levels. The upper level is much more sensitive than the lower ones. When the detector is mounted at the recommended height of 2 metres, the upper level enhances signals from intruders, making it easier to distinguish between them and a pet.

In addition, the active creep zone ensures catch performance close to the detector without compromising pet immunity.

The Pet DT uses its micro-processor to analyse the shape and length of the PIR pulses from pets and intruders (see diagram below).

The lens design is such that large, long pets are characterised by longer and flatter pulses, as only part of the pet is in the zone at any one time as the pet can at the same time be in a + zone and a -zone, leading to a reduction of signal. On the other hand, the zones are optimised to the size of an intruder and thus give a maximum + signal, followed by a maximum - signal.

In addition to the above benefits, the Pet DT has all the features and advantages of the proven DT series.

If not, officers may then provide follow up shots with the OC red for pain compliance as the impact of projectiles alone is painful, but when combined with OC particulate, the effect is entirely debilitating. If officers have used the green marking projectiles, subjects will wonder why they have been singled out in the crowd and marked with fluorescent green paint.
