Hikvision Wireless Magnetic Door Contact | DS-PDMC-EG2-WB
The Hikvision DS-PDMC-EG2-WB is a wireless magnetic contact for the Hikvision AX PRO alarm system. It detects the opening of a door or window (detection gap up to 43 mm) and reports to the control panel over Tri-X two-way wireless at 433 MHz, with a range of up to 1.2 km in free space.

Key Features
Opening Detection: The sensor and its magnet raise an alarm as soon as a protected door or window is opened. The maximum detection gap between the sensor and the magnet is 43 mm.
Slim Design: The slim body is designed for unobtrusive installation. It sits neatly on the frame without drawing attention.
Onboard Wired Input: The alarm input lets you wire an extra wired sensor to the contact, with normally closed, normally open and impulse count modes. This extends what one wireless transmitter can protect.

Secure Tri-X Wireless: Two-way RF communication at 433 MHz with AES-128 encryption and frequency hopping against jamming keeps the link to the panel reliable. The free-space range is up to 1.2 km.
Easy Setup: The contact is fully configurable remotely through the app. It supports power-up, remote ID and QR code enrollment.
Tamper Protection: Front and rear tamper protection reports any attempt to open or remove the contact. It also has environment temperature and signal strength indicators.
