Optex Products

This page gathers Optex intrusion detection: REDWALL long-range outdoor PIR detectors, garden and approach sensors, curtain PIRs, active infrared beams and the towers that hide them, REDSCAN laser scanners, a fibre optic fence system, indoor PIR and dual-tech detectors, and presence sensors for automatic doors. Mounting brackets, hoods, heaters, alignment tools and power units for the same detectors are here too.

Choosing Optex Products

Match the detector to the area it guards: a room, a garden approach, a long perimeter line, or a wall or roof that needs a laser or fibre system.

REDWALL long-range PIRs

REDWALL SIP detectors watch large outdoor areas and can trigger cameras. The SIP-404 covers 40 × 4 m in two independent near and far zones, the SIP-3020 covers 30x20m, and the SIP-100 draws a long, narrow 100 × 3 m curtain with separate far, near and creep alarm outputs. The SIP-HU heater unit keeps SIP detectors working in cold climates, and the AVF-1 viewfinder helps set the detection area during installation.

Garden and approach sensors

The VXI-AM is a hardwired dual-PIR outdoor detector with approach detection up to 12m, an IP55 rating and anti-masking. The QXI-DT-X8 adds dual technology for 12m and 120° coverage, with high and low mount options. For a boundary, the BXS-ST curtain PIR detects on both sides, 12m per side.

Beams, lasers and fibre

The SL-350QN is a 100m outdoor active infrared beam set for perimeter security. Towers such as the STW100 conceal beams, so an intruder cannot tell how many are fitted or at what height. REDSCAN laser detectors build a detection area in space: the RLS-2020I is a Grade 3 indoor laser sensor for skylights, walls and assets, and the RLS-3060SH identifies a moving object's size, speed and distance. The FD332 fibre optic unit protects two fence or wall zones, using sensor cable such as the SC3-C.

Indoor detectors

The FlipX FLX-S-DT combines PIR and microwave, with a rotatable lens for a wide 12m pattern or a narrow 18m one. The CX-702MKII is a Grade 2 indoor sensor for long-range detection in commercial and industrial buildings.

Frequently asked questions

Which REDWALL detector suits a long fence line?

The SIP-100 is built for it, with a long, narrow detection curtain of 100 × 3 m. It has separate far, near and creep outputs and anti-masking. For a shorter or wider area, the SIP-404 covers 40 × 4 m and the SIP-4010 covers 40 × 10 m, each with independent near and far zones.

Can an Optex detector trigger my CCTV cameras?

Yes, the REDWALL SIP detectors are made to trigger cameras. The SIP-404 has two zones with separate sensitivity selectors for camera preset and trigger control, and the SIP-100 has three outputs that connect to recorders, VMS and access control. The QXI-DT-X8 also connects to an alarm panel or a CCTV system.

Why fit infrared beams inside a tower?

A tower hides the beams, so an intruder cannot tell how many are fitted or at what height. Towers such as the STW100 and TW100 have an extruded aluminium frame with acrylic covers, and Optex dual and quad beams mount inside them. The SL-350QN beam set can also be mounted directly on a wall or pole.

Which Optex indoor detector suits a home with pets?

The FlipX FLX-S-DT is designed for pet tolerance, with a lens that creates human-sized detection areas. It combines PIR and microwave detection for homes and small commercial sites. The FLX-S-DT lens rotates between a wide pattern reaching 12m at 85 degrees and a narrow one reaching 18m.
