REDWALL SIP-3020/5 Outdoor Long-Range PIR Intrusion Detector, 30×20 m, IP65

Introduction to the REDWALL SIP-3020/5 and its key features

The REDWALL SIP-3020/5 is a purpose-built outdoor long‑range passive infrared (PIR) intrusion detector engineered to provide reliable perimeter protection for commercial and critical infrastructure sites. With a main coverage area of approximately 30 × 20 m (100 × 65 ft), an independent creep (look‑down) zone, active anti‑masking and robust weather protection (IP65), the SIP-3020/5 is designed to trigger CCTV, VMS events and alarm systems while minimising false alarms in challenging outdoor environments.

Key features at a glance

• Long‑range main coverage: 30 × 20 m (100 × 65 ft).
• Independent creep (look‑down) zone with separate output.
• Active IR anti‑masking and anti‑rotation/vandal detection.
• Intelligent automatic sensitivity management and selectable sensitivity levels for far/near/creep zones.
• Three independent detection outputs plus tamper/trouble outputs.
• Weather resistant for outdoor mounting (IP65 main unit; chassis IP55).

Detailed specifications and benefits

The SIP-3020/5 pairs hardware design with advanced processing to deliver dependable detection across a wide area while maintaining a low false alarm rate. Below are key technical specifications and the benefits they provide in real deployments.

• Detection method:Passive Infrared (PIR).
• Main coverage:30 × 20 m (100 × 65 ft).
• Creep (look‑down):≈3 × 5 m at 2.3 m mount; up to 6 × 9 m at 4.0 m mount.
• Number of PIR zones:74 zones (36 zones for under‑sensor zone).
• Sensitivity levels:4 levels (SH / H / M / L) selectable per far/near/creep.
• Power input:11–26 V DC; 22–26 V AC (24 VAC for optional heater).
• Current draw:≈45 mA max (12 V DC); ≈85 mA max (24 V AC); higher with heater.
• Alarm outputs:N.O./N.C., 28 V DC, 0.2 A max (per main/creep outputs); trouble & tamper outputs.
• Alarm / warm‑up:Alarm period ≈2 s; warm‑up ≈60 s.
• Operating temperature:−25 to +60 °C (−40 to +60 °C with optional heater).
• IP rating:Main unit IP65; chassis IP55.
• Mounting height:2.3–4.0 m.
• Dimensions (H×W×D):248 × 102 × 266 mm.
• Weight:≈1.4 kg.

• Long‑range coverage:The 30 × 20 m detection area lets a single unit cover extended sections of perimeter, reducing the number of sensors required for large, open sites such as car parks and industrial yards.
• Creep/under‑sensor detection:A dedicated look‑down zone provides a separate output for objects or people directly beneath or beside the sensor — crucial for preventing blind‑spot exploitation at fence bases, immediate perimeters or when mounted above access paths.
• Multiple independent outputs:With separate far/near/creep outputs you can map detection zones to different responses — for example, escalate to PTZ tracking for far detections, trigger lighting for near detections and log creep alarms separately for investigation.
• Anti‑masking & tamper detection:Active IR anti‑masking detects attempts to obscure the sensor, while a 3‑axis accelerometer senses rotation or vandalism. Both increase resilience against common attack vectors.
• Adaptive sensitivity:Intelligent automatic sensitivity management uses ambient temperature and illuminance to tune detection, reducing nuisance alarms from environmental changes while retaining detection reliability.
• Weatherproofing and ruggedness:IP65-rated main unit and a wide operating temperature range mean the detector performs reliably in rain, dust and temperature extremes when properly mounted and installed.

Use cases and scenarios where the SIP-3020/5 excels

The SIP-3020/5 is best suited to outdoor perimeter protection scenarios where long-range detection, reliable performance in varying weather and graduated zone outputs are required. Typical applications include:

• Perimeter protection for commercial sites:Warehouses, logistics centres and shopping centres benefit from extended coverage and separate creep detection to protect fence lines and entry points.
• Parking facilities and open lots:The detector covers large open areas effectively and can trigger CCTV recording and lighting to deter intruders or support incident investigation.
• Critical infrastructure and utilities:Power stations, water facilities and telecom sites require robust anti‑masking and tamper detection alongside reliable outdoor performance.
• CCTV-triggered event workflows:Integration with VMS or NVR platforms to start recording, push PTZ presets or raise operator alerts only when validated by PIR detection reduces false-event review workload.
• Hybrid systems with access control:Use the separate outputs to coordinate gates, barriers or interlocks depending on where a detection occurs (far vs creep), improving response accuracy.
• Harsh environmental sites:Sites subject to wind-blown debris, rain or temperature swings benefit from the SIP-3020/5’s adaptive sensitivity and IP65 protection to lower nuisance activations.

Comparisons with similar products and technologies

When sizing a perimeter-protection solution, it helps to compare the SIP-3020/5 not only with other long‑range PIR detectors but also with alternative sensor types such as microwave barriers, active infrared beam detectors and video analytics. Key comparative points:

• Versus short-range PIRs:Standard short‑range PIRs are ideal for doorway or corridor protection but lack the coverage footprint and separate creep zone of the SIP-3020/5. This product reduces the number of units needed for wide areas.
• Versus active IR beams:Beam detectors offer long-range detection along a linear path and can be very precise, but they are more vulnerable to alignment issues, foliage and false alarms from small animals. The SIP-3020/5’s multi-zone PIR approach is more tolerant of environmental clutter and provides richer zone data.
• Versus microwave sensors:Microwave sensors can penetrate certain obstructions and have long range, but they are more prone to false alarms caused by environmental motion (e.g., swaying vegetation) unless carefully tuned. The SIP-3020/5 combines PIR detection with intelligent algorithms to lower such nuisance activations.
• Versus camera-based analytics:Video analytics provide identification and richer situational context, but they depend on lighting conditions and camera view. Using the SIP-3020/5 to trigger cameras can create a layered approach: PIR for reliable detection and video for classification and forensic review.
• Versus competing long-range PIRs:The SIP-3020/5 stands out with its independent creep zone, active anti‑masking and three independent outputs — features often reserved for higher-end perimeter detectors. When compared on environmental resilience, IP rating and adaptive sensitivity, it performs strongly for outdoor, untended sites.

Conclusion — why the REDWALL SIP-3020/5 is a strong choice

The REDWALL SIP-3020/5 is a well‑rounded long‑range PIR intrusion detector that balances wide coverage, environmental resilience and practical features for real-world perimeter security. Its 30 × 20 m main coverage combined with a dedicated creep zone and three independent outputs gives system designers flexibility to map detections to appropriate responses. Active anti‑masking, tamper detection and adaptive sensitivity management improve reliability in outdoor conditions where nuisance alarms can otherwise overwhelm operators.

For organisations seeking a scalable, rugged and versatile detector to integrate with CCTV, VMS or alarm systems, the SIP-3020/5 offers a strong combination of performance and functionality. As with any security product, optimal results depend on correct siting, professional installation and system tuning to match local site conditions — when those elements are in place, this detector can serve as a dependable primary layer of perimeter detection.
