Digital temperature compensation
With this technology, the detector will automatically adjust the upper and lower alarm thresholds based on the external temperature. This helps it cope with temperature changes and maintain alarm sensitivity. Digital temperature compensation outperforms the traditional method of adjusting the detector amplifier gain. Increasing amplifier gain makes the device more susceptible to external interference from other devices, such as radios.
Animal-immune detection
Animals sometimes visit neighboring yards — often at night for a moonlight walk. They are harmless to property, so the detector will not trigger an alarm in such cases. Animal-immune detection technology reduces false alarms caused by animals to a minimum. This makes Hikvision’s intrusion detector an ideal choice for families with pets or for locations frequently visited by harmless wild animals.
Dual technology and tri-detection
Some detectors use PIR technology, which is effective at detecting living targets that emit body heat. Others use microwave technology to detect movement. By combining these two technologies, the intrusion detector will sound an alarm only when both sensors are triggered — indicating something that is both alive and moving. Using this dual technology helps reduce the likelihood of false alarms.
Tri-detection is another multi-technology method: two PIR sensors and one microwave sensor must be triggered at the same time for an alarm signal to be sent.
Anti-masking and anti-blocking
For planned burglaries or other incidents, thieves might cover or spray-paint detectors to mask them while the system is disarmed, then break in later knowing the system will not be triggered.
Anti-masking uses the microwave module to create a second microwave “bubble” that is always active and used solely to prevent masking. The microwave bubble is adjustable between 0 and 1 meter depending on the application, and it ensures any attempt to mask the detector is reported to the control panel.
Anti-blocking is similar to anti-masking, but it monitors the entire field of view for any blockage. The detector will send an alert to the alarm panel if the field of view is blocked or obstructed by objects such as a car, a box, or a pallet.
