Bosch PIR Detector Range - Indoor, Pet-Friendly, Panoramic, TriTech and Outdoor Motion Detection for Security Installations New Zealand

Exploring the Bosch PIR Range: Your Guide to Reliable Motion Detection

Essential Security Supplies

Reliable motion detection starts with choosing the right sensing technology for the environment, the expected traffic pattern and the installation conditions. Bosch PIR detectors give security installers and specifiers a broad set of options, from compact indoor PIR units to panoramic ceiling detectors, pet-friendly models, TriTech dual-technology sensors and outdoor detectors for harsher conditions.

This guide explains the current Bosch PIR options available from Essential Security Supplies, including their stated coverage areas, mounting considerations and best-fit applications across commercial, residential, industrial and perimeter security projects in New Zealand.

Choosing the right detector for each site

A PIR detector identifies changes in infrared energy caused by movement within its field of view. In a straightforward indoor space, a standard PIR can provide an effective and efficient detection solution. More demanding sites may benefit from microwave-assisted TriTech detection, Quad processing, anti-mask technology or weather-resistant construction.

The most important selection factors are the required coverage area, mounting position, likely sources of false alarms, environmental conditions and whether the site includes pets or other moving objects. A ceiling-mounted panoramic detector may be appropriate for an open room, while a wall-mounted detector can provide better control over the direction of detection in corridors, offices and smaller rooms.

For manufacturer-level information about intrusion detection technologies and system design, refer to the Bosch Security and Safety Systems resource library alongside the latest product documentation.

Standard Bosch PIR detectors for indoor coverage

The Bosch Blue Line Gen2 PIR range is designed for dependable indoor detection with practical installation features. The ISC-BPR2-W12 provides stated wall-to-wall coverage of 12 m x 12 m, with a high-density 77-zone, seven-layer pattern and a selectable lookdown lens providing three additional zones.

Dynamic temperature compensation helps maintain detection performance as environmental conditions change. The self-locking enclosure and flexible mounting height are also useful for installers working across different room layouts.

The ISC-BPR2-WP12 adds pet-friendly operation for sites where animals up to 20 kg may be present. It retains the stated 12 m x 12 m coverage and is intended to reduce unwanted alarm signals from pets while continuing to detect human intruders.

The ISC-BPR2-WP12 is suited to indoor areas where pet-friendly detection is required.

For installations requiring a compact ceiling-mounted solution, the DS936 and DS936-c listings provide 360-degree PIR coverage, a low-profile design and stated coverage of up to 7.5 m, depending on mounting height. Both listings specify mounting heights from 2 m to 3.6 m, with surface or semi-flush mounting and a sealed detector chamber.

The current catalogue contains both DS936 and DS936-c listings with the same stated feature set. Confirm the correct listing and model reference before finalising a bill of materials.

When TriTech detection is the better fit

TriTech detectors combine passive infrared and microwave detection. Using more than one sensing method can help installers address challenging conditions where a standard PIR may be more vulnerable to environmental movement or difficult detection patterns.

The ISC-BDL2-W12G is a wall-mounted Bosch Blue Line Gen2 TriTech detector with a stated 12 m x 12 m detection area. The current product listing specifies 10.525 GHz microwave detection, 9-15 V DC power, a normally closed dry output and a normally closed tamper connection. It is specified for a mounting height of approximately 2.2 m to 2.75 m.

The pet-friendly ISC-BDL2-WP12G also provides 12 m x 12 m coverage and combines PIR and microwave detection. Its listing specifies selectable pet-friendly operation for animals up to 45 kg, a 25 V DC power supply, 2.5 W power consumption and an operating temperature range of -30°C to +55°C. The enclosure dimensions are listed as 105 mm x 61 mm x 44 mm.

The ISC-BDL2-WP12G combines TriTech detection with selectable pet-friendly operation.

For higher-performance commercial interiors, the ISC-PDL1-WA18G Bosch Professional Series detector provides stated 18 m x 25 m coverage, field-selectable to 8 m x 10 m. The listing includes MANTIS anti-mask technology, sensor data fusion, Tri-focus optics, range-adaptive radar and cloak and camouflage detection technology.

These features make the ISC-PDL1-WA18G a strong candidate for commercial spaces where detector obstruction, unusual movement patterns or difficult internal layouts need to be considered during system design.

The ISC-PPR1-W16 is another Bosch Professional Series PIR listing for commercial indoor applications. However, the current product data contains a coverage discrepancy. The product title states 16 m x 22 m, while the description states 18 m x 25 m standard coverage with selectable 8 m x 10 m short-range coverage. Confirm the latest Bosch datasheet before specifying this model on a project.

360-degree detectors for open areas

Open-plan spaces, retail areas, reception zones and larger commercial rooms may benefit from ceiling-mounted 360-degree detection. Bosch panoramic models are designed to provide broad coverage from a central or strategically positioned ceiling location.

The DS9370 listing specifies 21 m x 360-degree TriTech detection, an adjustable lens and a mounting height range of 3 m to 7.6 m. Fully adjustable optics allow the installer to customise coverage, while the hinged chassis and base plate are intended to simplify installation and walk testing.

The DS9370 provides broad ceiling-mounted TriTech coverage with adjustable optics.

The DS939 listing is also described as a 360-degree ceiling-mounted motion detector with fully adjustable optics, a hinged chassis and base plate, high-efficiency LED walk testing and First Step Processing. Its stated maximum mounting height is up to 6.1 m.

When designing a 360-degree detection layout, check ceiling height, obstructions, partitions, air movement and the expected direction of travel. A panoramic detector may reduce the number of devices required in an open area, but the final position still needs to provide a clear detection pattern.

View our product for the DS9370, or View our product for the DS939.

Quad technology for challenging indoor layouts

The ISC-BPQ2-W12 Bosch Blue Line Gen2 Quad detector uses two individual sensors that process signals separately. Both sensors must activate before an alarm signal is generated, which can improve false-alarm immunity compared with a standard PIR in some challenging environments.

The product listing identifies Quad detection as particularly useful where cross-catch cannot be guaranteed or where an intruder may move quickly across the detection pattern. This can be relevant in corridors, awkward room layouts and locations where the detector needs to respond to purposeful human movement while disregarding smaller or less consistent sources.

The current listing confirms wall-to-wall coverage but does not state a specific coverage distance. Confirm the latest technical documentation for the required range, mounting height and installation limitations before using this model in a formal design.

Outdoor and anti-mask Bosch PIR options

Outdoor detection demands a different approach from standard indoor motion sensing. Weather, temperature changes, insects, small animals and moving vegetation can all affect performance, so the detector must be selected for the environment and installed according to the manufacturer's requirements.

The Bosch OD850-F1 is an outdoor TriTech detector with stated 15 m coverage and a 90-degree field of view. Its listing specifies PIR and microwave detection, Motion Analyzer II PIR signal processing, Linear Travel Distance microwave processing, selectable sensitivity, adjustable timed relay output and IP54 protection.

The OD850-F1 is designed for outdoor and other harsh-environment applications.

The OD850-F1 listing also describes immunity to drafts, insects and small animals. Even with these features, outdoor detectors should be positioned carefully, away from avoidable sources of movement and environmental interference.

For commercial indoor sites where an intruder may attempt to cover or obscure a detector, the ISC-CDL2-A15G adds anti-mask capabilities. Its listing specifies C2DT cloak and camouflage detection technology, passive infrared and microwave Doppler radar detection, First Step Processing, integrated end-of-line resistors, intelligent tamper and impact detection using a MEMS accelerometer, and active white-light suppression.

The ISC-CDL2-A15G listing states 40 ft, or approximately 12 m, detection and a 60-month warranty. Confirm the final product path and model details before ordering, as the current catalogue handle is shared with another Bosch listing.

Installation factors to confirm before specifying

Coverage figures are only one part of detector selection. Before finalising a Bosch PIR specification, confirm the mounting height, detection direction, room dimensions, expected movement path and any possible sources of unwanted activation.

  • Mounting position: Confirm whether the detector is intended for wall, ceiling, surface or semi-flush installation.
  • Coverage shape: Check whether the project requires a wide-angle, 360-degree, wall-to-wall or selectable short-range pattern.
  • Technology: Use standard PIR for suitable indoor areas, TriTech for more demanding environments, Quad for selected false-alarm challenges and anti-mask models where detector obstruction is a concern.
  • Pets and animals: Use a listed pet-friendly model where the site includes animals, and confirm the specified weight limit.
  • Environmental exposure: For external or harsh locations, confirm the required IP rating, temperature range, mounting protection and final installation method.
  • Wiring and power: Check supply voltage, alarm output, tamper connection, end-of-line requirements and panel compatibility before ordering.
  • Documentation: Use the latest Bosch datasheet for final measurements, coverage diagrams and installation clearances.

Making a practical Bosch PIR selection

For general indoor rooms, the ISC-BPR2-W12 provides a straightforward 12 m x 12 m Blue Line Gen2 PIR option. Where pets are present, the ISC-BPR2-WP12 or ISC-BDL2-WP12G may be more appropriate, depending on whether standard PIR or TriTech detection is preferred.

For open spaces, the DS936, DS936-c, DS9370 or DS939 can provide broad ceiling-mounted coverage. Commercial interiors with more demanding detection requirements may call for the ISC-PDL1-WA18G or ISC-CDL2-A15G, while the ISC-BPQ2-W12 is worth considering where Quad processing may help manage a challenging indoor layout.

For outdoor or harsh environments, the OD850-F1 is the Bosch option in the current range with stated outdoor suitability and IP54 protection. As always, final detector selection should be based on the current manufacturer's documentation, site conditions and the requirements of the complete intrusion alarm system.
