Hikvision AX PRO Series DS-PDMC-EG2-WB Wireless Magnetic Contact Reed Switch

Model: DS-PDMC-EG2-WB

Who This Is For

For installers and property owners building out a Hikvision AX PRO wireless alarm system who need reliable, low-maintenance detection at doors and windows. The DS-PDMC-EG2-WB is a slim magnetic contact reed switch that fits neatly into residential and light commercial installations - think entry doors, sliding windows, internal fire doors, and ground-floor access points - without requiring cable runs to each zone. Operating on Tri-X Wireless at 433MHz, it pairs directly with AX PRO hubs and reports open/close events and tamper alerts in real time. With a 5-year battery life from a single CR123A cell and an IP65 rating, it suits installations where low ongoing maintenance matters and where the sensor may be exposed to dust or moisture in partially covered locations. Compact at just 22.5mm wide, it sits flush against most frames without drawing attention.

What This Device Actually Does

Who Buys This Model

• AX PRO alarm installers: Adding door and window zones to a Hikvision AX PRO hub deployment, where running wired zone cables to each opening is impractical or cost-prohibitive in an existing building.
• Residential property owners retrofitting security: Wanting to add magnetic contact detection to internal or external doors without disturbing walls, skirtings, or ceiling spaces with new cabling.
• Small business owners on AX PRO systems: Protecting shopfront doors, rear access points, or roller door frames across a single site where the wireless hub is already installed and additional zone sensors are needed.
• Security integrators managing multi-tenancy sites: Deploying identical sensors across multiple units or apartments on a single AX PRO system, where the 5-year battery life keeps per-unit maintenance calls to a minimum.

Honest Assessment

The DS-PDMC-EG2-WB does its core job well: it reliably detects door and window openings via the 43mm magnetic gap, transmits wirelessly on the AX PRO Tri-X protocol, and stays operational for up to 5 years on a single battery. The dual-panel tamper protection is a genuine advantage over single-tamper competitors at this price point. The IP65 rating adds flexibility for partially exposed locations that many indoor-only sensors cannot handle. What it will not do is work outside a Hikvision AX PRO ecosystem - this sensor is not compatible with third-party alarm panels or generic 433MHz receivers. It also does not provide glass-break or vibration detection; for those functions, a separate sensor type is needed. If your installation requires a hardwired zone sensor for integration with a non-Hikvision panel, a wired reed switch from the Security Australia range would be the correct path instead.

Before You Buy

Quick Fit Check

• Good match if: You are expanding an existing Hikvision AX PRO wireless alarm system and need additional door or window zones without running new cables - the Tri-X Wireless pairing makes adding zones straightforward.
• Good match if: The installation involves locations with dust, condensation, or occasional moisture exposure such as garages, laundries, or covered external entries, where the IP65 rating provides durability that standard indoor-only sensors do not.
• You may need a different model if: Your alarm panel is not a Hikvision AX PRO hub - a wired magnetic contact sensor or a wireless sensor compatible with your specific panel brand would be more suitable, and both options are available at securityaustralia.com.au.

Real-World Scenarios

How It Compares

• Choose this if: You are running a Hikvision AX PRO wireless alarm system and need a low-maintenance, wireless door or window zone sensor with IP65 durability and dual-panel tamper protection built in.
• You may need a different model if: Your alarm panel is not an AX PRO hub, or you require a hardwired zone input - a wired magnetic contact sensor would be the correct product type for those installations.
• Pairs well with: Hikvision AX PRO wireless PIR motion detectors and wireless sirens, building out a full perimeter detection layer across all entry points on the same hub.

Common Questions

1. Will this sensor work with my existing alarm panel if it is not a Hikvision AX PRO?

   No. The DS-PDMC-EG2-WB uses Hikvision's proprietary Tri-X Wireless protocol at 433MHz and is designed to pair exclusively with AX PRO series hubs. It will not register with generic 433MHz receivers or third-party alarm panels. If your panel is not an AX PRO hub, you need a wired reed switch or a wireless sensor that matches your panel's protocol.

2. Does this sensor work on sliding windows as well as hinged doors?

   Yes. The opening contact detection method works on any door or window type where the body and magnet separate as the opening moves - hinged doors, sliding sash windows, sliding glass doors, and casement windows are all suitable, provided the gap between the two components does not exceed 43mm in the closed position.

3. How long will the battery actually last, and which battery does it use?

   The rated battery life is up to 5 years under normal operational conditions using a single CR123A lithium battery. Actual life varies with transmission frequency - installations where the door or window is opened many times daily will reduce this figure. CR123A cells are widely available in hardware and electronics stores across Australia. The AX PRO hub monitors and reports battery status remotely, so low-battery warnings appear on the panel and Hik-Connect app before the sensor fails.

4. What does the IP65 rating mean, and can I install this sensor outdoors?

   IP65 means the sensor is fully dust-tight and protected against low-pressure water jets from any direction. The listed application scenario is indoor, but the IP65 rating means it performs reliably in garages, laundries, covered external doorways, and other partially exposed environments where condensation or dust are present. It is not rated for direct rain exposure or submerged conditions.

5. What happens if someone tries to remove or cover the sensor?

   Both the front cover and the rear mounting plate have independent tamper switches. Removing the front cover or pulling the unit away from the mounting surface each generate a separate tamper alert at the AX PRO hub immediately. This is reported through Hik-Connect as a tamper event distinct from an open/close alarm, so the panel operator knows exactly what type of interference occurred. This dual-tamper design is confirmed in the specifications for this model, supplied by Security Australia.

6. How many of these sensors can I add to one AX PRO hub?

   The maximum number of wireless devices per AX PRO hub depends on the specific hub model in your system, not the sensor itself. The DS-PDMC-EG2-WB occupies one wireless zone per unit. Check your AX PRO hub's specification for total wireless zone capacity before planning a large multi-door deployment, as hub models vary in the number of supported wireless peripherals.

7. Will this sensor detect glass breaking or vibration if someone tries to force a window?

   No. The DS-PDMC-EG2-WB detects only the physical separation between the magnet and the reed switch body - it triggers when the door or window opens past 43mm. It does not detect vibration, impact, or glass breakage. For those threats, a separate vibration or glass-break detector would need to be added as an additional zone on the AX PRO hub.
