Hikvision Wireless Outdoor Triple-Signal Detector | DS-PDTT15AM-LM-WB
The Hikvision DS-PDTT15AM-LM-WB is a two-way wireless outdoor triple-signal detector with anti-masking for the Hikvision AX PRO alarm system. It combines passive infrared and 24 GHz microwave detection, covers up to 15 m, is rated IP65 for outdoor use and is designed to raise the alarm before an intruder breaks into the house.

Triple-Signal Detection: Two passive infrared sensors (top and bottom) and a 24 GHz microwave sensor work together with Tri-Signal logic. Requiring the signals to agree helps the detector tell a real intruder from outdoor disturbances, and anti-sway analytics are supported.
Built for Outdoors: The IP65 housing and an operating range of -25 °C to 60 °C let it protect the outside of the property, so an alarm can be raised before an intruder reaches a door or window.
Active IR Anti-Masking: The detector reports attempts to cover or block its view, and front and rear tamper protection reports attempts to open or remove it. This makes it harder to defeat the detector before a break-in.

Adjustable Coverage and Pet Immunity: Coverage is 90° and can be adjusted within 180°, and a pattern mask is included to adapt the zone to your yard or entrance. Pet immunity is rated up to 40 kg, with Auto and Low sensitivity settings.
Long-Range Secure Wireless: Tri-X two-way wireless at 433 MHz with AES-128 encryption and frequency hopping gives up to 1 km range in free space. Five CR123A batteries give up to 5 years of standby time.
