Hikvision Wireless Water Leak Detector | DS-PDWL-E-WB
The Hikvision DS-PDWL-E-WB is a battery-powered wireless water leak detector for the Hikvision AX PRO alarm system. It has an IP66 waterproof design with a probe on an extension cable, sends an AES-128 encrypted two-way signal to the panel on 433 MHz, and runs on one CR2450 battery with a standard battery life of 3 years.
Color: White

Waterproof Design with Probe: The housing is rated IP66, and the detector has a probe on an extension cable. This lets the probe sit at the point to be monitored while the detector body is fixed nearby.
Flexible Installation: The detector can stand directly on the surface, or be fixed to a wall with screws or sponge tape. That makes it easy to fit in tight spaces without drilling.

Secure Tri-X Wireless: It talks to the AX PRO panel over two-way 433 MHz RF with AES-128 encryption and frequency hopping against jamming. The leak alarm reaches the panel without any wiring.
Remote Configuration: The detector is fully configurable remotely through the app, and it reports signal strength and environment temperature. It can be enrolled by power-up, remote ID or QR code, and front and rear tamper protection reports attempts to open or remove it.
