Overview
The Optex REDWALL SIP-404/5 is a hard‑wired external passive infrared (PIR) detector engineered for wide‑area perimeter and approach detection. It is designed to trigger CCTV systems and PTZ camera presets, providing reliable long, narrow coverage and reduced false alarms through adaptive detection logic.

• Coverage: 40 × 4 m main detection area with a dedicated adjustable creep/under‑unit zone.
• Intelligent detection: Automatic sensitivity adjustment to ambient temperature and illumination to reduce false alarms.
• Multi‑zone outputs: Three independent outputs (far / near / creep) for camera presets or separate alarm actions.
• Anti‑tamper & anti‑masking: Built‑in anti‑rotation accelerometer for vandal/tamper detection and active IR anti‑masking.
• Weatherproof: Main unit rated IP65 for outdoor use; suitable for mounting at 2.3–4.0 metres.

Use cases
Ideal for perimeter fencing, pathways, service roads and other long, narrow approaches where video activation and PTZ cueing are required. Suited to both commercial installations and professional CCTV/security integrators.

Installation & safety
Install at the recommended 2.3–4.0 m height for optimum pattern coverage. Electrical installation should be performed by a qualified technician; consult the Optex datasheet/manual for wiring diagrams, heater options and exact installation instructions. Check the manufacturer datasheet for certification details (CE/UKCA) and variant‑specific requirements.
