Detailed specifications and benefits
Understanding the technical details helps you decide whether this sensor fits your needs. Below is a breakdown of the most relevant specifications and the practical benefits they deliver.
The DS‑PDMCS‑EG2‑WE(B) uses a traditional magnet/reed opening contact. The main sensor measures 29 × 69 × 10 mm and the matching magnet 14 × 69 × 10 mm. This slim profile makes it easy to hide inside or alongside a frame, reducing visual impact while maintaining reliable operation. The maximum recommended gap between sensor and magnet is 52 mm, offering flexibility for various door and window types.
Operating on 868 MHz with Hikvisions Tri‑X two‑way protocol, the detector benefits from a robust wireless link designed for alarm system use. AES‑128 encryption and frequency hopping enhance security and reduce the risk of jamming or interception. Two‑way communication means the device can confirm enrolment and signal health back to the AX‑Pro panel, improving reliability compared with one‑way devices.
Hikvision lists an approximate transmission range of ~1 km line‑of‑sight. In real installations, range will depend on building materials and RF interference — expect shorter distances in dense urban or multi‑storey environments. The unit is intended for wall/wood mounting and Hikvision advises avoiding direct mounting on metal surfaces, which can degrade radio performance.
Powered by a single CR2450 (3 V) battery, the detector achieves up to ~3 years of standby life under typical conditions. The small coin cell keeps the device compact while providing adequate longevity for most domestic and light commercial uses. LED indicators give visual cues during installation and alarm events, and remote configuration via the app helps manage battery‑saving settings and diagnostics.
Front and rear tamper sensors protect against tampering or removal, and the device includes signal and temperature indicators to assist with troubleshooting. Enrolment is flexible (power‑up, Remote ID or QR code), simplifying integration into AX‑Pro installations and speeding up commissioning for installers.
Important: Hikvision lists this model as discontinued. Stock may be limited and pricing can be variable as inventory is depleted. Warranty information is not provided in the listing; customers should confirm warranty terms and post‑sales support with their vendor prior to purchase. Also note that certifications are listed as 'INSUFFICIENT DATA' in the provided specification set — verify required approvals for your jurisdiction if compliance is critical.
Use cases and scenarios where the product excels
The DS‑PDMCS‑EG2‑WE(B) is particularly well suited to several common scenarios:
- Residential installations:Its slim, low‑profile appearance makes it ideal for homeowners who want unobtrusive security sensors on front doors, internal doors, patio doors or windows without the bulk of larger contacts.
- Light commercial fitouts:Small shops, offices and clinics often need reliable entry monitoring without obvious equipment. The detector provides secure wireless signalling and tamper protection while avoiding an industrial look.
- Retrofit projects:For upgrades to existing doors and frames where routing cables is difficult or where aesthetics matter, the slim wireless contact simplifies installation and reduces visible hardware.
- AX‑Pro integrated systems:Installers already using Hikvisions AX‑Pro panels will find straightforward compatibility, remote configuration via the app and consistent enrolment workflows, reducing setup time and commissioning errors.
- Locations needing secure RF links:Where RF reliability and encryption are priorities (e.g., alarm signalling in multi‑occupancy buildings), Tri‑X two‑way communication and AES‑128 encryption give added peace of mind over basic one‑way devices.
Comparisons with similar products on the market
When choosing a magnetic contact sensor, installers weigh factors such as size, wireless technology, security, battery life and ease of installation. Heres how the Hikvision DS‑PDMCS‑EG2‑WE(B) stacks up against common alternatives:
Slim sensors like this Hikvision model are preferred where discretion is desired. Standard bulk sensors are more visible and sometimes offer larger batteries or additional features (e.g., built‑in reed switch with extended tamper mechanics), but they compromise on appearance and may be harder to fit in tight frames.
Consumer smart‑home contacts often use Zigbee, Z‑Wave or proprietary one‑way RF (433 MHz) solutions. Tri‑X two‑way at 868 MHz provides better range (line‑of‑sight) and confirmation of signal delivery to the panel. AES‑128 and frequency hopping further enhance security compared with many consumer products that lack strong encryption or anti‑jamming techniques.
The CR2450 coin cell in this model balances compact size with reasonable capacity. Some competitors use CR2032 (smaller capacity) or larger batteries in bigger housings for multi‑year life. If ultra‑long battery life is a priority, larger devices may offer longer deployments between battery changes, but with a larger footprint.
Hikvisions quoted ~1 km line‑of‑sight is competitive for 868 MHz alarm‑grade sensors; many consumer alternatives are limited to a few hundred metres. However, real‑world performance depends on building materials, metal structures and RF noise — always test on site before final placement.
Customer testimonials and installer feedback
At the time of writing there are no official customer reviews included with the product datasheet and Hikvision lists the model as discontinued, which has limited community feedback from recent purchases. That said, feedback patterns from similar Hikvision AX‑Pro devices and slim magnetic contacts commonly report the following themes (illustrative, not direct quotes):
- Installers appreciate the slim format for flush mounting and the tidy finished look it delivers on doors and windows.
- Two‑way RF and AES encryption are seen as clear advantages over basic one‑way consumer sensors in professional alarm systems.
- Battery life of around two to three years in typical domestic use is considered acceptable; customers note the benefit of remote diagnostics to check battery and signal status.
- Some installers caution about radio performance on metal frames and recommend trial placement to ensure consistent signalling back to the AX‑Pro panel.
If you require authentic testimonials, ask the vendor for references or case studies from their installer customers, or request stock photos and installation examples from remaining stock pools before purchase.

Warranty details are not specified here; verify warranty and support terms with the seller before ordering, and confirm compliance certifications for your region if required.
Conclusion: why choose the DS‑PDMCS‑EG2‑WE(B)?
The Hikvision DS‑PDMCS‑EG2‑WE(B) is a strong option for installers and end users who value a discreet, professionally finished security installation with reliable, secure wireless communications. Its slim form factor, AES‑128 encrypted two‑way Tri‑X communications at 868 MHz, tamper protection and convenient enrolment methods make it particularly attractive for residential and light commercial projects where aesthetics and dependable alarm signalling matter.
However, the models discontinued status means buyers should confirm stock availability, warranty and certifications before committing. Where inventory exists and the AX‑Pro ecosystem is already in use, this detector offers a sensible balance of size, security and battery life for routine door and window monitoring tasks.
For precise pricing, warranty and compliance information, contact your Hikvision distributor or installer and confirm the currency for the listed prices so RRP and conversions can be finalised.
