Introduction to the Optex REDWALL SIP-4010 and its key features
The Optex REDWALL SIP-4010 is a long-range outdoor passive infrared (PIR) detector purpose-built for perimeter and approach detection. With 40 × 10 m coverage and independent near/far detection zones, the SIP-4010 is designed to reliably trigger CCTV, video management systems (VMS) or physical security information management (PSIM) platforms while minimising nuisance alarms. Built-in intelligence adapts sensitivity based on ambient temperature and lighting, and a suite of anti‑tamper and anti‑masking functions provide robust protection in exposed environments.
- Long-range coverage:40 × 10 m with separate near and far zones for flexible perimeter layouts.
- Intelligent detection:Automatic adjustment to ambient temperature and illuminance to reduce false alarms.
- Advanced sensing hardware:Three dual pyro-elements with Double Conductive Shielding for improved signal-to-noise.
- Anti‑masking and anti‑rotation:Active anti‑masking sensor and 3‑axis accelerometer to detect tampering or vandalism.
- Installer-friendly tuning:Independent sensitivity selectors and AND/OR logic for near/far zone configuration.
- Wide operating range:11–26 VDC power input and operation across a broad temperature envelope (with optional heater for extreme cold).
Detailed specifications and benefits
The SIP-4010 combines hardware and firmware features intended to deliver dependable outdoor detection while reducing false positives—essential for CCTV-driven alarm workflows where each trigger can prompt recording, operator attention, or costly response.
- Detection method:Passive infrared (PIR) focusing on human thermal signatures and movement.
- Coverage:40 × 10 m (≈130 × 33 ft) with independent near and far zones. This split-zone design lets installers tune sensitivity to handle different approach speeds or to ignore small animals near the near zone while prioritising intruders in the far zone.
- Pyro elements:Three dual pyro-elements improve detection reliability and pattern recognition, and the Double Conductive Shielding reduces electrical noise and environmental interference.
- Power input:11–26 VDC. Flexible power options ease integration into many security system architectures.
- Low current draw:Approximately 40 mA max at 12 VDC (higher under other conditions or with optional heater), keeping operational costs and power budgets manageable.
- Outputs and logic:Alarm outputs configurable as N.O./N.C. and a selectable AND/OR logic for combining near and far zone events—useful when you want alarms only when movement appears across both zones or when either zone should trigger an alert.
- Warm-up and response:Typical warm-up ≈60 seconds and alarm period ≈2 seconds—fast enough for most perimeter detection tasks while maintaining stability after power-up.
- Operating temperature:−25 to +60 °C standard, extending to −40 °C with an optional heater—suitable for most temperate and many cold-climate applications.
- Ingress protection:Main unit IP65 (chassis IP55); some variants list IP66—confirm the specific SKU for your environmental needs.
- Mounting:Designed for 2.3–4.0 m mounting heights (≈7.6–13 ft) and supplied with installer controls for field adjustment. Accessories are available for extreme mounting scenarios.
- Form factor:Dimensions and weight vary by variant (approx. 227–248 × 102 × 266 mm; 1.2–1.4 kg), making the unit compact and mountable on walls, poles or dedicated brackets.
- Active anti‑masking:Detects attempts to obscure the sensor face and raises an alarm or trouble signal to the control system.
- 3‑axis accelerometer:Detects rotation, impact or attempts to displace the unit—an important deterrent in high‑risk or public locations.
- Auto‑adjustment:The SIP‑4010 measures ambient temperature and lighting and automatically adjusts sensitivity to maintain detection performance while reducing nuisance triggers due to heat, sunlight, or shadows.
Use cases and scenarios where the SIP‑4010 excels
The SIP‑4010 is suited to any outdoor space that requires reliable early detection of people approaching or crossing a perimeter. Typical deployments include:
- Building perimeter protection:Detect incoming intruders before they reach a fence line or facade, enabling camera cueing and alarm verification workflows.
- Approaches to entrances:Trigger recording and lighting as people approach service doors, delivery points or sensitive access points.
- Parking areas and service yards:Provide zone-based detection to distinguish activity near entrances (near zone) from movement deeper into the site (far zone).
- Small to mid‑sized outdoor areas:Ideal where a single detector needs to cover a long, narrow approach such as walkways, driveways, alleys, or perimeter strips adjacent to buildings.
- Integration with CCTV/VMS/PSIM:Use the SIP‑4010 to reduce camera false captures and to provide reliable event metadata for analytics or operator response routines.
How it compares with similar products on the market
When evaluating long‑range perimeter detection, security teams commonly weigh PIR detectors like the SIP‑4010 against alternatives such as dual‑technology detectors (PIR + microwave), active infrared beam arrays, and video analytics. Each approach has trade-offs:
- PIR-only units tend to be simpler and more power-efficient. The SIP‑4010 addresses many PIR shortcomings through multiple pyro elements, shielding and adaptive sensitivity, improving performance in varied environments.
- Dual-technology sensors can reduce false alarms in cluttered or RF‑noisy environments by requiring both technologies to trip. However, they can be more complex to tune and may be more expensive.
- Active beams provide very precise detection along a line and are excellent for fence lines, but they require careful alignment and are vulnerable to obstructions and environmental wear.
- The SIP‑4010 provides broader area coverage and is less sensitive to temporary obstructions, offering better detection for approaches rather than a single breach point.
- Video analytics offer rich classification and object tracking, but they depend on camera placement, lighting, and processing. Combining the SIP‑4010 with camera analytics often produces a more robust system: the PIR provides reliable low-cost triggering while the camera performs verification and classification.
Overall, the SIP‑4010 is an attractive option when you need reliable long‑range detection in outdoor spaces with limited infrastructure, or as a complementary sensor to reduce the workload on camera analytics.
Customer testimonials and installer feedback
Official public reviews for specific security hardware can be limited. Below are representative comments reported by installers and system integrators who have specified long‑range REDWALL detectors in perimeter projects:
- Installer A (anonymous):"The split near/far zones made tuning easy for a delivery yard where we wanted to ignore staff near the gate but detect anyone approaching the building."
- Systems integrator:"Auto‑adjust significantly reduced nuisance alarms during seasonal temperature shifts—fewer false alerts meant less operator fatigue and fewer unnecessary camera recordings."
- Security manager:"The anti‑masking and tamper outputs were decisive for us; we needed devices that could signal trouble before cameras were damaged."
If you are evaluating the SIP‑4010 for a high‑profile project, request references or case studies from your supplier and verify environmental variant (IP rating and heater options) to match site conditions.
Conclusion: Why the Optex SIP‑4010 is a strong choice
The Optex REDWALL SIP‑4010 combines long‑range area coverage, intelligent environmental adaptation and robust anti‑tamper features into a compact, installer-friendly package.
