Hikvision AX Hybrid Series DS-PDBG8-EG2 Wired Glass Break Detector, Omni Directional Microphone Sensor, 8M

Model: DS-PDBG8-EG2

Who This Is For

Property managers specifying wired detection zones for glazed entry points will find the Hikvision AX Hybrid DS-PDBG8-EG2 a direct fit. This glass break detector uses an omni-directional microphone sensor to pick up the acoustic signature of breaking glass within 8 metres and across a 120-degree coverage angle - wide enough to protect multiple windows from a single ceiling or wall mount. It connects into wired alarm panels via selectable end-of-line resistors in 5 values (1K, 2K2, 4K7, 5K6, 6K8), which makes it compatible with a broad range of existing panel configurations without additional components. The 9-16 VDC wide voltage input and polarity reverse protection reduce installation risk, particularly across multi-zone commercial fit-outs where cabling runs are long or power supplies vary. Suited to retail shopfronts, office lobbies, jewellers, and residential properties with large glass facades.

What This Detector Actually Does

Who Buys This Model

• Alarm Installers on Retail Fit-Outs: Adding glass break zones to shopfronts and glazed facades where door contacts alone do not satisfy the insurer's perimeter detection requirements.
• Commercial Property Managers: Specifying wired detection for office lobbies, reception areas, and ground-floor glazing in buildings where a managed panel system is already in place.
• Jewellers and High-Value Retailers: Protecting display windows and glass display cases where smash-and-grab is a known risk and early detection before entry is the priority.
• Multi-Zone Residential Installers: Adding dedicated glass break coverage to large homes with floor-to-ceiling windows or glazed sliding doors that fall outside the effective range of standard passive IR detectors.

Honest Assessment

The DS-PDBG8-EG2 does its job well within a defined set of conditions. The 8-metre range and 120-degree coverage angle are genuinely useful in open-plan retail and office spaces, and the 5-value selectable EOLR removes most of the compatibility friction when retrofitting into an existing panel. The wide 9-16 VDC input and polarity protection are practical touches that reduce installation errors across large commercial jobs. This is a wired device, so it belongs on supervised panels where loop integrity monitoring is in use - that is where its EOLR flexibility actually pays off. It will not work as a standalone detector or with wireless-only systems. Acoustic detection also has limitations: very thick laminated glass, high ambient noise environments (machinery, live music venues), or glass mounted directly against soft furnishings can affect detection reliability. For those environments, a dedicated dual-technology detector or multiple units positioned closer may be a better fit. Available through Security Australia for integration into Hikvision AX Hybrid panel installations.

Before You Buy

Quick Fit Check

• Good match if: You are adding glass break zones to an existing wired alarm panel with supervised loops - the 5 selectable EOLR values cover the most common panel resistance requirements without additional components.
• Good match if: Your installation involves a retail shopfront or open office where a single ceiling-mounted detector needs to cover multiple windows within an 8-metre radius and 120-degree arc.
• You may need a different model if: Your system is wireless or you are working without a supervised wired panel - a wireless glass break detector compatible with your specific panel protocol would be the appropriate product type to review on securityaustralia.com.au.

Real-World Scenarios

How It Compares

• Choose this if: You are working with a supervised wired alarm panel and need a detector with broad EOLR compatibility - the 5 selectable resistance values handle most commercial panel configurations without additional external components.
• You may need a different model if: Your installation uses a wireless alarm panel - a wireless glass break detector from the compatible wireless sensor range would be the appropriate product type to consider on securityaustralia.com.au.
• Pairs well with: A wired panel with supervised zones, passive infrared detectors for internal motion coverage, and door/window contacts for a complete layered perimeter detection system.

Common Questions

1. Will this detector work with any wired alarm panel, or only Hikvision panels?

   It works with most wired alarm panels that use supervised zones. The DS-PDBG8-EG2 outputs a standard normally-closed contact with selectable EOLR values (1K, 2K2, 4K7, 5K6, 6K8), which covers the supervised loop resistance requirements of the majority of commercial and residential panels on the market. It is not restricted to Hikvision panels, though it is part of the Hikvision AX Hybrid Series product line.

2. Does this detector work for all types of glass?

   It is designed to detect the acoustic signature of breaking glass across various glass types. However, performance can vary with very thick laminated safety glass or specialised acoustic-dampening glazing, which absorbs more of the breakage sound before it reaches the microphone. For installations with non-standard glazing, position the unit as close to the glass as possible within the 8-metre limit and test detection during commissioning.

3. What does the 120-degree coverage angle mean in a real installation?

   It means the omni-directional microphone has a defined acoustic sensitivity zone spanning 120 degrees in front of the detector. In practice, mount the unit so the glass panels to be protected fall within that arc. For a corner installation covering two adjacent walls of windows, you would need 2 detectors or to verify that both glass surfaces fall within the single 120-degree field from a central ceiling position. Always test with a glass break simulator during commissioning.

4. How do I select the correct EOL resistor value for my panel?

   Check your alarm panel's technical documentation for the supervised zone loop resistance specification - this is the value the panel expects to read when the zone is in a normal (not alarmed) state. Match the panel's required resistance to one of the 5 available values on the DS-PDBG8-EG2 (1K, 2K2, 4K7, 5K6, 6K8) and set the on-board selector accordingly. If your panel requires a value not in this range, an external resistor wired in series or parallel will be needed.

5. What is the operating voltage and will it work with standard panel aux power outputs?

   Yes. The DS-PDBG8-EG2 operates on 9-16 VDC, which covers the aux power output range of most common alarm panels (typically 12V nominal). The built-in polarity reverse connection protection means accidental reverse wiring during installation will not damage the unit, which is a useful safeguard on busy multi-zone commercial jobs.

6. Does this detector require a separate tamper zone on the panel?

   Yes. The tamper output is a separate contact that needs to be wired to a dedicated tamper input or zone on your panel for it to function as intended. If your panel does not have a free tamper input, the tamper circuit can be wired into a spare detection zone, though you should confirm this approach meets the requirements of your relevant Australian Standard compliance or insurer specification. The tamper feature is confirmed on this model - the wiring configuration will depend on your specific panel. Security Australia can advise on panel compatibility if needed.

7. Will high ambient noise environments cause false alarms with this detector?

   Potentially, yes. Acoustic glass break detectors listen for specific frequency patterns associated with glass fracturing. In environments with sustained high-frequency noise - such as certain industrial settings, venues with live music, or spaces with heavy machinery - the false alarm rate can increase. For these environments, a dual-technology detector (combining acoustic detection with a secondary sensor technology) would be a more appropriate product type to consider.
