OPTEX - SIP-3020 - REDWALL Outdoor Long-Range PIR Detector for CCTV, 30 x 20 m

SIP-3020: OPTEX REDWALL Outdoor Long-Range PIR Detector, 30 × 20 m

The OPTEX REDWALL SIP-3020 is an external, long-range passive infrared (PIR) detector built to trigger CCTV, for small and mid-sized outdoor areas. Its fan-shaped detection area reaches 30 × 20 m (OPTEX's figure) from a mounting height of 2.3 to 4 m, split into a far zone and a near zone that each have their own sensitivity setting. It reads the ambient temperature and light level and adjusts its sensitivity on its own, and it uses three dual pyro-elements with OPTEX's Double Conductive Shielding.

It is built to detect and resist tampering: anti-masking with a photo-beam, anti-rotation with a 3-axis accelerometer, a reinforced polycarbonate housing, and separate trouble and tamper outputs. The main unit is rated IP65 (chassis IP55), and OPTEX lists it as BS8418 compliant (UK).

Technical specification

Specification from OPTEX's product page and datasheet for the REDWALL SIP-3020 / SIP-4010 / SIP-404 series.

What you'll need

• A 12 V DC or 24 V AC supply. If you add the optional SIP-HU heater for very cold sites, the supply must be 22 to 26 V AC, so a 12 V DC site needs a separate AC supply for it.
• Something to trigger: an alarm input on a recorder, camera, video management system or monitoring transmitter, wired to the N.O. or N.C. relay. For example, our Hikvision DS-7608NI-G2/4P/4G NVR has 4 alarm inputs.
• Optional OPTEX accessories (not included): AVF-1 Area View Finder for aiming, OPM-WT audible walk tester, SIP-MINI HOOD sun and snow shield, SIP-HU heater.

Frequently asked questions

What area does the SIP-3020 cover?

A fan-shaped area of 30 × 20 m (100 × 65 ft) in OPTEX's figures, mounted between 2.3 and 4 m high. The far zone can be switched off to shorten the range.

How does it trigger my CCTV?

It has a relay alarm output (N.O. and N.C., 28 V DC 0.2 A max.). Wire it to an alarm input on your recorder, camera or monitoring equipment, and set that to record, alert or call up the camera when the detector trips.

What are the far and near zones?

The detection area is split in two, each with its own sensitivity (SH, H, M or L). It also has a detection logic selector (AND / OR); OPTEX's installation manual explains each setting.

Can it be turned or covered without anyone knowing?

Anti-rotation (a 3-axis accelerometer) detects the detector being turned, and anti-masking (a photo-beam) detects the lens being masked. It has separate trouble and tamper outputs (both N.C.) to wire to your equipment.

Will it work in cold weather?

It is rated from -25 °C to +60 °C. With the optional SIP-HU heater (not included) it works down to -40 °C, on a 22 to 26 V AC supply.

Is it BS8418 compliant?

OPTEX lists the SIP-3020 as BS8418 compliant (UK). BS 8418 is the British Standard code of practice for detector-activated remotely monitored video systems, so compliance also depends on how the whole system is designed, installed and monitored.

Can I return it?
