Hikvision Wireless Slim Magnetic Contact | DS-PDMCS-EG2-WB
The Hikvision DS-PDMCS-EG2-WB is a wireless opening detector that reports the first signs of intrusion through a door or window. Its slim body is designed for window frames and a discreet installation. It detects openings with a gap of up to 52 mm and talks to the alarm panel over Tri-X two-way 433 MHz wireless with up to 1 km range in free space.
Key Features
Slim, Discreet Design: The sensor measures 29 x 69 x 10 mm and the magnet 14 x 69 x 10 mm, so the contact fits into window frames where a standard contact would show. The whole unit weighs 38 g.

Reliable Opening Detection: The contact triggers when the magnet moves away from the sensor, with a maximum detection gap of 52 mm. Front and rear tamper protection reports any attempt to open or remove the device.
Secure Two-Way Wireless: Tri-X two-way RF at 433 MHz with AES-128 encryption and frequency hopping keeps the link stable and protected against jamming. The range is up to 1 km in free space.

Easy Enrollment and App Setup: The detector can be enrolled by power-up, remote ID or QR code, and it is fully configurable remotely through the app. Environment temperature and signal strength indicators help during installation.
Long Battery Life: One CR2450 battery (3 V) gives up to 3 years of battery life. No wiring is needed to the door or window.
