Motion detector VIDICON PIR-CRT — PIR passive infrared curtain sensor

VIDICON PIR-CRT is a passive infrared curtain motion detector engineered to detect movement within a narrow, focused detection zone. As a curtain-type PIR sensor, it generates a linear beam of sensitivity that is suited for monitoring windows, doorways, perimeters and other specific access lines. The detector is designed for integration into alarm and security systems where precise, directional motion detection reduces false alarms and concentrates coverage on a defined protection plane.

Advantages

The VIDICON PIR-CRT offers directional detection with a narrow field of view that minimizes coverage spillover and helps avoid triggering from irrelevant movement outside the protected line. Its passive infrared sensing requires no active illumination, enabling low-power operation and quiet performance. The construction and optical design provide stable sensitivity along the curtain axis, facilitating targeted perimeter and access control. The detector’s form factor supports installation near windows and doorways where a focused sensing curtain is preferred.

Suitable for

• Perimeter protection along fences, walls or narrow corridors
• Monitoring windows and glazed facades for line-based intrusion detection
• Protecting doorways, gates and access passages
• Integration with wired alarm panels and access control systems

Key specifications

• Detection type: passive infrared (PIR) curtain sensor
• Coverage: narrow, linear detection zone designed for directional monitoring
• Typical applications: window, doorway and perimeter line protection
• Power consumption: low-power passive operation (no active illumination)
• Installation: wall or frame mounting oriented to create a curtain of coverage

How to use

Install the VIDICON PIR-CRT so its optical axis aligns with the line or plane to be protected. Mount the detector at the recommended height and orientation for curtain coverage across the monitored opening, ensuring there are no obstructions that could interrupt the linear sensing zone. Connect the detector to the security system following the system manufacturer’s wiring diagram and configure sensitivity and alarm reporting according to the panel’s procedures. Test the curtain by walking through the protected line at varying speeds and distances to confirm reliable detection without undue false triggers.

Usage recommendations

For optimal performance, avoid pointing the sensor at heat sources, HVAC outlets or reflective glass surfaces that can cause uneven thermal backgrounds. Use the detector as part of a zoned protection strategy together with complementary sensors (e.g., volumetric PIRs or magnetic contacts) to cover areas outside the curtain line and reduce the chance of false alarms.
