Detailed specifications and benefits
Understanding the technical specifications of the DS-PDC15-EG2-WE(B) helps clarify where it excels and what to expect in real-world use. Below is a concise breakdown of the key specifications and the practical benefits each delivers.
- Detection method:Passive Infrared (PIR) — reliable and well proven for human-motion detection.
- Detection range:15 m curtain reach — allows protection of tall windows or long narrow entryways from a single mounting point.
- Detection angle:6.3° narrow beam — concentrates detection into a curtain rather than a broad area to limit unwanted triggers.
- Detection zones:18 zones across 8 planes — multi-zone segmentation improves localization and reduces false alarms from minor environmental changes.
- Detectable speed:0.3–2 m/s — tuned to differentiate typical human movement from very slow or very rapid non-intrusive events.
- White light filter:6500 lux — helps reject false triggers from strong light sources falling on the sensor.
Benefits: The narrow beam and multi-zone detection make the detector particularly precise for perimeter protection. It focuses on specific approaches (for example, a window sash or doorway) and is less likely to alarm from activity elsewhere in the room.
- Optics & processing:Sealed optics, digital processing and temperature compensation for stable performance across conditions.
- Creep-zone protection:Yes — protects against low-profile intrusions close to the mounting wall.
- LED indicator & tamper:Visual alarm indicator and both front and rear tamper detection.
- Mounting height:Recommended 2.4–3.6 m wall mount for optimal curtain alignment.
Benefits: Sealed optics reduce dust and insect contamination, digital processing improves signal discrimination, and tamper detection protects the device from being disabled or physically removed.
- Technology:Tri-X two-way wireless communication ensures device and panel can acknowledge messages.
- Frequency:868 MHz — a common band for security sensors in many regions.
- Encryption:AES-128 — industry-standard encryption for robust over-the-air protection.
- Frequency hopping:Yes — improves resistance to RF interference and jamming.
- Range (free-space):Up to 1.6 km — note that indoor range is substantially lower and site testing is recommended.
Benefits: Two-way communication and encryption add reliability and security to wireless signalling. Frequency hopping and Tri-X provide better resilience in RF-noisy environments compared with simple single-channel transmitters.
- Power:CR123A ×1 (typical 3 V).
- Battery life:Up to 5 years in standby under typical conditions.
- Dimensions & weight:65.5 × 103 × 48.5 mm; 128 g — compact and discreet.
- Operating temperature:−10 °C to 55 °C; humidity 10–90% non-condensing.
- Compliance:EN 50131 Grade 2, Environmental Class II.
Benefits: Long battery life reduces maintenance visits. Compact size and a recommended mounting height make it easy to integrate into most properties. Compliance with EN 50131 Grade 2 makes it suitable for many residential and commercial risk scenarios where recognized standards are required.
Use cases and real-world scenarios
The curtain PIR’s focused detection pattern means it shines in applications where you want to protect linear or narrow approaches rather than entire rooms. Typical scenarios include:
- Window protection:Place the detector along the wall to create a vertical curtain over windows — ideal for ground-floor glazing or bay windows where intruders might attempt entry.
- Doorway and corridor coverage:Protect a narrow entrance corridor or side door where a wide-angle detector would be overkill and more susceptible to false triggers.
- Display cases and retail fronts:Provide perimeter protection for shopfront windows or merchandising displays without monitoring the whole sales floor.
- Controlled internal zones:Use in offices or back-of-house areas to monitor staff-only corridors or secure access points.
Because it lacks pet immunity and is a single-technology PIR, avoid mounting where pets will cross the beam or where very small animals may trigger the sensor. For locations with significant air currents, direct sunlight or heavy vibration, careful placement and testing are essential.
Comparisons with similar products on the market
When considering the Hikvision curtain PIR against alternatives, compare along several axes: detection pattern, wireless robustness, false-alarm resistance, battery life and additional technologies (for example, dual-technology units that pair PIR with microwave sensing).
- Versus standard wide-angle PIRs:Curtain PIRs are more focused and less likely to be triggered by general room movement. For window and door protection the Hikvision curtain detector is a better fit than a broad-beam detector designed for open spaces.
- Versus dual-technology sensors:Dual-tech models (PIR + microwave) can offer better false-alarm immunity in challenging environments but are typically more expensive and may require more tuning. The Hikvision device prioritizes simplicity, low power draw and precise curtain coverage rather than the extra discrimination layer that microwave provides.
- Versus other wireless curtain detectors:Tri-X two-way communication, AES-128 encryption and frequency hopping place the Hikvision unit firmly in the modern wireless category. Compared to older single-way transmitters or unencrypted devices, it offers better security and reliability. Battery life up to five years is competitive for high-quality wireless detectors.
- Considerations:If pet immunity is a must, or if you need outdoor-rated curtain detection, you may need to look at other models specifically engineered for those requirements. Similarly, for extremely long or complex perimeters, multiple curtain sensors or complementary devices may be preferred.
Customer feedback and reviews
While individual experiences vary by installation and environment, installers and end users frequently highlight the following themes for curtain PIRs like the Hikvision DS-PDC15-EG2-WE(B):
- "Clear, focused coverage — great for protecting shopfronts and ground-floor windows." Many installers appreciate the 15 m reach and narrow beam for targeted perimeter protection.
- "Long battery life and easy app configuration." Remote setup via AX Pro and the low-maintenance battery life are often cited as time-savers for installers.
- "Good wireless performance but check signal strength on-site." Several users report that indoor conditions reduce range, so a site survey before permanent mounting avoids surprises.
- "Reliable in normal indoor environments, but placement is critical to avoid false alarms from drafts or reflections."
These comments are representative of common feedback on curtain PIRs and align with the Hikvision unit’s design focus on precision and low maintenance.
