Detailed specifications and benefits
The DS‑PDMC‑EG2‑WE(B) features a slim profile that suits modern doors, windows and frames where aesthetics and low visibility matter. The main unit measures approximately 24 mm × 104 mm × 24.4 mm and is paired with a small magnet of 13 mm × 34.4 mm × 11.4 mm, weighing in at just 59 g. The unobtrusive design reduces the likelihood of accidental damage or tampering while maintaining effective contact sensing.
This sensor uses opening contact detection with a maximum recommended gap of 43 mm, making it suitable for most doors and windows, including some sliding and French doors. Front and rear tamper protection helps ensure that attempts to remove or interfere with the unit are reported to the alarm system. An integrated blue LED provides a visible alarm indicator for quick on‑site verification.
Wireless performance is a standout aspect: Tri‑X two‑way RF operating at 868 MHz provides reliable communication and interference resistance. Frequency hopping improves robustness in noisy RF environments, and AES‑128 encryption protects wireless transmissions from interception or spoofing. Under ideal, free‑space conditions the device can transmit signals up to approximately 1.6 km — a practical advantage for larger properties or sites where line‑of‑sight between device and panel is possible.
Two auxiliary wired inputs expand the sensor's versatility, allowing connection of external sensors or switches using normally‑closed (NC), normally‑open (NO) or pulse count modes. Enrollment options include power‑up, remote ID and QR code scanning, simplifying setup for installers and enabling app‑based or technician‑assisted configuration.
The DS‑PDMC‑EG2‑WE(B) runs on a single CR123A battery (3 V). Typical standby life is up to five years depending on activity and reporting rate, making the sensor low‑maintenance for installations where access for battery changes is limited. Operating temperature is rated from −10 °C to 55 °C with storage rated to −20 °C to 60 °C and relative humidity tolerance of 10%–90% non‑condensing.
Use cases and scenarios where the product excels
- Residential front and back doors: The slim profile keeps the contact discreet on attractive doorframes while maintaining reliable detection.
- Windows and French doors: The 43 mm gap tolerance supports multiple mounting positions and some decorative mouldings.
- Retail display cases and cabinets: Small magnets and compact housing reduce visual intrusion in shops and showrooms.
- Server rooms or restricted access cupboards: Front and rear tamper protection and encrypted RF communications add physical and electronic security for sensitive areas.
- Outbuildings and garages (indoor placement): Long RF range and two‑way communication make it practical where the central panel is at some distance, subject to line‑of‑sight and building materials.
- Integrations requiring external triggers: Two auxiliary inputs let installers connect additional contact points, vibration sensors or reed switches into a single device for consolidated monitoring.
Comparisons with similar products on the market
When comparing the Hikvision AX Pro Slim magnetic contact to other slim wireless contacts, several factors influence choice: RF protocol and security, battery life, enrollment convenience, input flexibility, tamper protection and price.
Many consumer‑grade contacts rely on proprietary short‑range RF with basic security. The Hikvision unit uses Tri‑X two‑way RF with frequency hopping and AES‑128 encryption, which aligns it more closely with professional‑grade sensors and provides stronger protection against interception and replay attacks.
Rated transmission up to 1.6 km (free space) is generous for a compact wireless contact. Comparable slim contacts typically specify shorter ranges under ideal conditions; real‑world range depends on walls, metalwork and interference. The two‑way communication used here offers improved reliability and status feedback compared with one‑way designs.
Not all slim contacts offer auxiliary wired inputs. The inclusion of two configurable inputs (NC/NO/pulse count) makes the Hikvision device more adaptable for complex installations where multiple sensors or external triggers need to be consolidated into a single zone.
Up to five years standby from a CR123A is competitive; some competitors provide similar long life on lithium cells, while cheaper units may sacrifice life for lower cost. The common CR123A format is widely available, simplifying maintenance.
With a suggested retail price around $39.95, the Hikvision DS‑PDMC‑EG2‑WE(B) sits in the mid‑range of wireless magnetic contacts. It provides features typical of professional systems (tamper, encryption, auxiliary inputs) without a premium that high‑end branded alternatives may command, making it a strong value for installers looking to balance capability and cost.
Customer testimonials and typical user feedback
There are no formal, attributable customer testimonials included here. However, based on the device's feature set and common installer feedback trends for similar Hikvision AX Pro devices, typical comments might include:
- "Installation was straightforward — slim form factor fits tight frames and the QR enrollment saved time."
- "Battery life is excellent; low‑activity doors run for years without a change."
- "We appreciate the auxiliary inputs — saved us from adding an extra device for a nearby sensor."
- "Strong RF link to the control panel with good tamper reporting helps with compliance on commercial installs."
Professional integrators also tend to value the encrypted communications and two‑way RF for larger systems where reliability and security are essential.

Installation tips and practical advice
- Follow Hikvision AX Pro installation guidance and local regulations for wiring and tamper placement.
- Verify the magnet alignment and maintain the gap within 43 mm to avoid false alarms or missed detections.
- Consider mounting orientation and door movement paths — slim magnets are versatile but must not contact moving hardware.
- Test RF connectivity at the intended installation point; walls and metal can reduce range significantly compared to free space figures.
- Use QR or remote ID enrollment to speed up commissioning and to ensure correct device mapping in the panel.
- Dispose of replaced batteries per local regulations and check for firmware or panel compatibility updates periodically.
