Introduction: Hikvision DS‑PDSK‑P(B) Wired Shock Detector — what it is and why it matters
The Hikvision DS‑PDSK‑P(B) Wired Shock Detectoris a compact, surface‑mount device designed to detect impacts and vibrations at vulnerable access points such as doors, windows, safes, ATM housings and display cases. Built around a piezoelectric shock sensor with on‑board digital processing, this detector combines accurate impact detection with adjustable sensitivity, tamper protection and a visible alarm indicator. For anyone specifying or installing perimeter and asset protection systems — from professional installers to DIY security enthusiasts — the DS‑PDSK‑P(B) offers a discreet, reliable option that integrates into wired alarm systems.
- Piezoelectric shock/piezo sensor for accurate impact and vibration detection
- Adjustable sensitivity through a potentiometer (fine/coarse plus gross‑attack override)
- Digital background‑noise filtering to minimise false alarms
- Front anti‑opening tamper contact and normally‑closed (NC) alarm output
- Blue alarm LED for clear local indication
- Low current draw and wide DC supply range (9–16 V DC, typical 12 V)
- Compact surface‑mount form factor for discreet indoor installation
Detailed specifications and benefits
Understanding the technical capabilities of the DS‑PDSK‑P(B) helps clarify where it performs best and how to integrate it into a system. Below are the key specifications and the practical benefits they deliver.
- Detection method:Piezoelectric shock sensor — detects mechanical shock and vibration rather than acoustic glass frequencies.
- Detection range:Up to a 2.5 metre radius (installation dependent).
- Sensitivity:Potentiometer adjustment with fine and coarse settings, plus a gross‑attack override for forced impact detection.
- Alarm output:Normally closed (NC) contact suitable for wired alarm panels.
- LED indicator:Blue alarm LED for local visual confirmation.
- Transmission:Wired — stable connection, no RF interference concerns.
- Power supply:9–16 V DC (typical 12 V).
- Current consumption:Approximately 13–30 mA (model/variant dependent — consult datasheet).
- Environmental ratings:Operating temperature −10 °C to 55 °C; storage −20 °C to 60 °C; operating humidity 10%–90% RH.
- Physical:Dimensions 30 × 108 × 22 mm; weight approx. 37.5 g.
- Mounting:Surface / wall mount for discreet indoor placement.
- Reliable impact detection:Piezo sensors respond to mechanical shock rather than relying on sound patterns, making them effective against direct attacks on doors, frames, safes and housings.
- Tailored sensitivity:The adjustable potentiometer allows installers to tune the detector to the mounting surface and local environment — lowering nuisance alarms while retaining protection against genuine attacks.
- False alarm reduction:Built‑in digital background‑noise filtering reduces false triggers from innocuous vibrations (foot traffic, HVAC, street noise), improving alarm reliability.
- Tamper protection:The front anti‑opening tamper contact helps detect attempts to remove or disable the detector itself.
- Low power and wired stability:The wide supply range and modest current draw make the unit compatible with most alarm panels and power supplies, and wired connections avoid RF congestion or pairing issues common to wireless devices.
- Compact and discreet:Small physical size and surface‑mount design help keep the detector unobtrusive in retail, banking and residential environments.
Use cases and real‑world scenarios where DS‑PDSK‑P(B) excels
The DS‑PDSK‑P(B) is most suitable in situations where direct mechanical attacks are a primary threat. Typical use cases include:
- Doors and windows:Mounted on door frames or window sills to detect forced entry attempts or prying with tools.
- Safes and secure cabinets:Protects safe housings and locker doors where direct impact or drilling attempts may occur.
- ATM housings and kiosks:Detects attempts to break into machine housings during tampering or theft attempts.
- Retail display cases:Ideal for showcases where asset protection is needed but unobtrusive hardware is preferred.
- Asset‑sensitive installations:Server cabinets, evidence lockers, artwork displays and other locations where physical tampering is a risk.
Installation guidance: for best results, follow the Hikvision datasheet and user manual recommendations for mounting surface type, sensitivity setting and wiring. Proper placement and tuning are essential to balancing sensitivity and false alarm immunity.
Comparisons with similar products
When evaluating the DS‑PDSK‑P(B), it helps to compare it against two common alternatives: acoustic glass‑break detectors and wireless shock sensors.
- Acoustic glass‑break detectors listen for frequency signatures of breaking glass and are excellent for covering large glazed areas from a central point. However, they can be sensitive to environmental noise and may require more careful placement and testing in noisy locations.
- Piezo shock detectors like the DS‑PDSK‑P(B) respond to mechanical impact on the surface where they are mounted. They are often more suitable for protecting frames, partitions, safes and housings where focused physical attacks occur. They typically generate fewer false alarms in certain environments because they detect actual surface shock rather than airborne sound.
- Wired detectors provide a stable connection with no battery lifecycle to manage and are preferred in professionally managed systems where tamper resistance and constant power are required.
- Wireless models offer installation flexibility and faster deployment for retrofit applications, but they require battery changes and can be subject to RF interference or range limitations. The DS‑PDSK‑P(B) is ideal when a reliable, always‑powered connection is required.
- Compact profile and low power draw make it easy to integrate into existing alarm loops without adding significant load.
- Adjustable sensitivity with gross‑attack override gives installers a quick way to ensure detection of aggressive attacks while tuning out everyday vibrations.
- Front tamper contact and a visible blue alarm LED improve on‑site diagnostics and tamper awareness compared with some basic shock sensors.
Customer feedback and installer impressions
Official customer reviews for specific models vary by region. Below are representative, anonymised impressions from installers and users who have experience with piezo shock detectors and similar Hikvision products. These are illustrative summaries rather than verbatim verified testimonials.
- "Great little unit for door frames — small enough to hide and easy to tune. We used the coarse setting for a high‑traffic retail door and it held up well without false alarms." — Commercial installer.
- "Good value for purpose. The tamper contact is a useful feature and the blue LED makes it clear when an alarm has occurred during site checks." — Small business owner.
- "Prefer wired shock sensors for ATM housings over wireless because of the power reliability. This model’s adjustable sensitivity helped when mounting on different metal housings." — Systems integrator.
Potential buyers should consult local distributors and product pages for region‑specific reviews and certification information.
