Dual motion detector VIDICON PIR-CRT-MW — microwave + PIR sensor, model PIR-CRT-MW

VIDICON PIR-CRT-MW is a dual motion detector that combines passive infrared (PIR) and microwave sensing technologies to detect occupancy and intrusion indoors. The sensor uses PIR to sense thermal changes caused by moving people or animals and a microwave Doppler module to detect motion through frequency shifts. The combined sensing approach improves detection reliability and helps reduce false alarms from environmental disturbances. The device is designed to integrate with alarm panels, access control systems and automated lighting controls in homes and commercial premises.

Advantages

The combination of PIR and microwave sensing offers complementary detection: PIR responds to heat signatures while the microwave module tracks movement even in low-contrast conditions. This dual-technology approach increases immunity to typical false triggers such as small temperature fluctuations, fan drafts or lighting changes. The detector is suitable for standard indoor mounting and provides stable operation for continuous monitoring. Its design supports straightforward integration with central alarm systems and building automation.

Suitable for

• Intrusion detection in residential and commercial indoor spaces
• Occupancy sensing for automated lighting control
• Integration with alarm panels and access control systems
• Areas requiring reduced false alarm rates, such as corridors, offices and reception areas

Key specifications

• Detection technologies: passive infrared (PIR) and microwave Doppler sensor
• Intended mounting: indoor use, wall or corner mounting
• Detection coverage: area motion detection for typical room sizes (coverage depends on mounting height and environment)
• Target detection: human occupancy and moving objects generating thermal contrast or Doppler shift
• Environmental operating conditions: designed for standard indoor temperature and humidity ranges (avoid direct exposure to severe moisture or outdoor elements)
• Output: alarm/contact signal compatible with standard alarm panels and control inputs

How to use

Install the detector at the recommended mounting height and position to cover the intended area, avoiding direct air vents, windows with strong sunlight or sources of rapid temperature change. Connect the detector output to the alarm panel or control system following the system wiring diagram and ensure correct power supply as specified by the control equipment. After installation, perform a walk-test to confirm the covered zones and adjust orientation or mounting location if necessary. Regularly inspect the device for dust accumulation and ensure the sensing window remains clean for reliable operation.

Usage recommendations

For optimal performance, mount the detector where the field of view covers common movement paths and avoid aiming it directly at HVAC outlets or large glass surfaces. Use the dual-technology detector in locations where reducing false alarms is important, and schedule periodic tests as part of routine security system maintenance.
