Hikvision DS-PDP18-EG2 AX Hybrid Series Wired internal 18m PIR detector

Model: DS-PDP18-EG2

Who This Is For

When specifying wired detection for commercial or residential alarm systems, the Hikvision DS-PDP18-EG2 is built for installers who need reliable passive infrared coverage across mid-to-large indoor spaces. With an 18m detection range, 85.9-degree angle, and 52 detection zones, it suits open-plan offices, retail floors, warehouses with internal offices, and larger residential rooms where single-point coverage needs to be thorough. The detector integrates with Hikvision AX PRO panels, making it the natural wired PIR choice for installers already working within that ecosystem. Selectable EOL resistors also allow it to work with most third-party control panels, giving installers flexibility across mixed-brand projects. Mounting height range of 1.8m to 2.4m suits standard ceiling heights without additional brackets in most Australian residential and commercial applications.

What This Detector Actually Does

Who Buys This Model

• Alarm system installers: Specifying wired detection on Hikvision AX PRO panel installations where a native, fully integrated PIR is preferred over third-party devices.
• Commercial fit-out contractors: Covering open-plan offices, showrooms, and retail floors where 18m range and 52 detection zones reduce the number of detectors required across large areas.
• Residential security installers: Installing perimeter detection in larger rooms or hallways and taking advantage of the optional pet mask for homes with small-to-medium dogs or cats up to 10kg.
• Multi-brand panel installers: Using selectable EOL resistors to integrate the DS-PDP18-EG2 into existing non-Hikvision wired alarm systems without changing resistor hardware.

Honest Assessment

The DS-PDP18-EG2 does several things well for a wired PIR at this price point. The combination of 52 detection zones, 3D optics, creep-zone coverage, and digital temperature compensation gives it a genuinely more thorough detection profile than basic single-zone PIRs. Sealed optics reducing insect-triggered false alarms is a practical benefit that directly affects service call frequency in commercial installs. The selectable EOL resistors are a genuine convenience for mixed-panel environments. Where this detector has limits: it is an indoor-only unit and is not rated for external installation. Pet immunity requires the optional mask accessory - it is not built in by default - so confirm that accessory is included in your order if pets are present. For sites with animals larger than 10kg, or for outdoor perimeter detection, a different detector type is more suitable. The DS-PDP18-EG2 is available through Security Australia as part of the Hikvision AX Hybrid Series wired detection range.

Before You Buy

Quick Fit Check

• Good match if: You are wiring a Hikvision AX PRO system and need a native PIR detector with 18m range and full volumetric coverage including creep-zone protection for an open-plan indoor space.
• Good match if: You are working on a mixed-brand wired alarm installation and need a PIR with selectable EOL resistors that can be configured to match your existing panel's supervision requirements.
• You may need a different model if: Your site requires outdoor perimeter detection or pet immunity for animals over 10kg - a dual-technology outdoor PIR or a detector with built-in pet immunity at a higher weight threshold would be more suitable for those applications.

Real-World Scenarios

How It Compares

• Choose this if: You need 18m indoor coverage with 52 zones, creep-zone protection, and digital temperature compensation in a wired PIR that integrates with Hikvision AX PRO panels or accommodates selectable EOL resistors for other panels.
• You may need a different model if: Your installation requires outdoor perimeter detection, pets above 10kg need to be ignored, or the site has specific conditions like extreme temperature swings that require a dual-technology PIR/microwave detector for additional confirmation before triggering.
• Pairs well with: Hikvision AX PRO wired alarm panels, wired zone expanders for multi-zone commercial installations, and wired indoor siren modules that trigger on confirmed detection events.

Common Questions

1. Will this detector work with my existing non-Hikvision alarm panel?

   Yes, in most cases. The DS-PDP18-EG2 features selectable EOL resistors, which means the end-of-line resistance value can be configured to match the supervision requirements of most wired alarm panels on the market. Confirm your panel's required EOL values before installation and set the resistors accordingly during wiring.

2. Does the pet immunity come built in or does it require an accessory?

   It requires the optional pet mask accessory - it is not active by default. Pet immunity up to 10kg is achieved by fitting the pet mask, which physically modifies the lower detection pattern of the lens. If pets are present at the property, order the pet mask at the same time as the detector.

3. What does creep-zone protection actually mean in practice?

   It detects movement directly beneath the detector, which is the blind spot most standard PIRs miss entirely. Standard single or dual-element PIR lenses point outward, not downward. The DS-PDP18-EG2's 3D optics include a dedicated lower detection layer so an intruder cannot crawl or crouch under the sensor to avoid triggering it.

4. Will this detector work outdoors or in a garage?

   No. The DS-PDP18-EG2 is rated for indoor installation only. Garages exposed to wind, rain, insects, or wide temperature swings will cause nuisance alarms or premature failure. For outdoor perimeter detection or partially exposed spaces like carports and covered loading docks, a dedicated outdoor-rated PIR with appropriate IP ingress protection is the correct product type. Security Australia stocks outdoor PIR detectors suitable for those environments.

5. How does digital temperature compensation affect detection reliability?

   It maintains consistent sensitivity as ambient temperature rises toward body temperature. Standard PIR detectors work by detecting the contrast between a moving human and the background temperature. As room temperature climbs toward 35-37 degrees Celsius, this contrast shrinks and detection reliability drops. Digital temperature compensation automatically increases sensitivity to compensate, keeping the 18m detection range accurate across varying conditions.

6. What mounting height does this detector require?

   Between 1.8m and 2.4m. The detection pattern, creep-zone coverage, and zone distribution are calibrated for this height range. Installing outside these limits will change where the zones land on the floor, potentially reducing coverage depth or leaving gaps in the detection field. Sites with higher ceilings should check whether an alternative mounting configuration is supported before ordering.

7. Does this detector work with the Hikvision AX PRO panel natively?

   Yes. The DS-PDP18-EG2 is part of the Hikvision AX Hybrid Series and is designed for direct integration with AX PRO wired alarm panels. This means zone labelling, status monitoring, and tamper detection are handled within the AX PRO interface without requiring additional configuration bridges or adaptors.
