Key Capabilities
Wireless Door & Window Detection
The detector monitors the relationship between the main sensor and magnetic contact to identify when a protected door or window opens. Hikvision specifies a maximum detection gap of 43 mm, allowing flexible positioning on suitable indoor frames.
Tri-X Two-Way Wireless
Hikvision Tri-X provides two-way 433 MHz RF communication with AES-128 encryption and frequency hopping. The system is designed to provide reliable encrypted communication between the detector and a compatible AX PRO control panel.
Up to 1.2 km Free-Space Range
The published wireless transmission range is up to 1.2 km in free space. A signal-strength indicator helps installers assess the mounting location, although walls, metal surfaces, reinforced structures and interference can reduce real-world range.
Front & Rear Tamper Protection
Front and rear tamper protection helps the alarm system detect attempts to open the detector or remove it from its installed position, adding protection against physical interference with the wireless contact.
Two External Alarm Inputs
Two external inputs allow compatible wired detection circuits to be connected to the magnetic contact. Normally closed, normally open and impulse-count operation are supported, allowing the device to extend beyond its own built-in opening-contact function.
Up to 5 Years Battery Life
A single replaceable CR123A 3 V battery powers the detector, with Hikvision specifying up to five years of standard standby life. Battery monitoring through the AX PRO environment assists with planned maintenance and replacement.
Best For
- Residential doors and windows: Adds wireless opening detection without running alarm cable back to the AX PRO panel.
- Offices and retail premises: Suitable for monitoring entry doors, windows, stockrooms and other indoor access points.

Why Choose the DS-PDMC-EG2-WB-B
The DS-PDMC-EG2-WB-B provides more flexibility than a basic wireless reed contact by combining long-range encrypted Tri-X communication with external-input support, tamper protection and system monitoring features. Its maximum 43 mm magnetic detection gap gives installers useful positioning tolerance, while the two external inputs can bring compatible wired contacts into the AX PRO wireless environment. Signal-strength indication, temperature reporting and multiple enrolment methods simplify commissioning, and the replaceable CR123A battery offers up to five years of standard standby operation. Available through Security Wholesalers, the black version is particularly useful for retrofit alarm installations and darker door or window frames where a compact, discreet AX PRO magnetic contact is preferred.
Buyer Decision Tips
Buyer Tip: Avoid installing the detector directly onto metal surfaces where possible. Metal can affect the magnetic switching distance and wireless performance, so test both the detection gap and Tri-X signal strength at the final mounting location before commissioning.
Buyer Tip: The 1.2 km transmission figure is measured in free space. Real-world range depends on walls, building materials, panel location and RF interference, so use the built-in signal-strength indication rather than assuming the maximum published distance will be achievable inside every property.

Choosing the Right Model
- Choose the DS-PDMC-EG2-WB(B) if: You need an indoor AX PRO magnetic contact with 1.2 km free-space Tri-X range, external inputs and front/rear tamper protection.
- Choose the white version if: The protected door or window frame uses a light finish and a white detector will provide a less visible installation.
- Choose an outdoor magnetic contact if: The detector will be directly exposed to rain, weather or outdoor environmental conditions.
- Choose a dedicated wired detector if: The site already has suitable alarm cabling and wireless communication is unnecessary.
FAQs
- What does the Hikvision DS-PDMC-EG2-WB(B) detect?
The Hikvision DS-PDMC-EG2-WB(B) is a wireless magnetic opening detector for compatible AX PRO alarm systems. It is intended for doors, windows and similar openings, using the relationship between the main sensor and magnetic contact to detect when the protected opening changes state. Hikvision specifies a maximum detection gap of 43 mm, although final positioning should follow the installation guide and be tested after mounting.
- How far can the DS-PDMC-EG2-WB(B) communicate wirelessly?
Hikvision specifies a Tri-X wireless transmission range of up to 1.2 km in free space. The detector uses two-way 433 MHz RF communication with AES-128 encryption and frequency hopping. Real installation range can be lower because walls, metal surfaces, reinforced concrete, interference and panel placement affect RF performance, so the signal-strength indicator should be checked at the intended mounting location before final commissioning.
- Does the DS-PDMC-EG2-WB(B) have tamper protection?
Yes. The DS-PDMC-EG2-WB(B) provides front and rear tamper protection. This allows the AX PRO system to detect attempts to open the detector or remove it from its mounting surface when tamper monitoring is correctly enabled. The feature is useful for fixed door and window contacts because it helps distinguish normal opening activity from physical interference with the alarm device itself.
- Can the DS-PDMC-EG2-WB(B) accept external wired inputs?
Yes. Hikvision documentation for the DS-PDMC-EG2-WB(B) specifies two external inputs, with support for normally closed, normally open and impulse-count operation. This allows the wireless magnetic contact to act as a bridge for compatible wired detection circuits in addition to its own opening-contact function. The external device and wiring method should be matched to the supported input configuration before installation.
- What battery does the DS-PDMC-EG2-WB(B) use?
The detector uses one CR123A 3 V battery, and Hikvision specifies standard standby battery life of up to five years. Actual service life can vary with wireless conditions, alarm activity, temperature, external-input use and battery quality. The detector also supports low-voltage monitoring through the AX PRO environment, allowing battery replacement to be planned before the device becomes unavailable.
- What is the maximum magnet detection gap?
Hikvision specifies a maximum detection gap of 43 mm for the DS-PDMC-EG2-WB(B). The practical break and make distances can vary with the direction of movement, mounting surface and whether nearby material is ferromagnetic. For reliable operation, align the sensor and magnet using the positioning marks, avoid unnecessary metal influence where possible and perform a full open-and-close test after installation.
- Is the DS-PDMC-EG2-WB(B) suitable for outdoor use?
The published application scenario for the DS-PDMC-EG2-WB(B) is indoor use. Hikvision specifies operation from -10°C to 55°C with 10% to 90% humidity, but no outdoor IP weather-protection rating is listed for this model. For exposed doors, gates or other outdoor locations, use a detector specifically designed and rated for the environmental conditions rather than assuming indoor temperature tolerance makes this unit weatherproof.
- Who should choose the Hikvision DS-PDMC-EG2-WB(B)?
Choose the DS-PDMC-EG2-WB(B) when a compatible AX PRO installation needs a wireless magnetic contact with up to 1.2 km free-space Tri-X range, front and rear tamper protection, external input support and long battery life. When planning the detector through Security Wholesalers, confirm the AX PRO panel frequency, mounting surface, required magnet gap and whether any external wired detector will be connected before commissioning.
