Qolsys Inc QZ8103-840 Wireless Pir Image Sensor V3

Product Description

The QOLSYS INC QZ8103-840 is a wireless passive infrared (PIR) image sensor designed for use in security and alarm systems. This third-generation device detects motion within a protected space and captures image data to support alarm verification. It is intended for installation by licensed security technicians and integrators working on residential or light commercial intrusion detection systems. The sensor communicates wirelessly, eliminating the need for signal wiring runs to the panel, which simplifies retrofit installations in finished spaces.

The QZ8103-840 is suited for interior spaces where motion detection combined with visual verification is required. Typical installations include living areas, hallways, and entry points in residential properties, as well as small office or retail environments. The wireless design makes it a practical choice for both new construction and retrofit projects where running low-voltage wire is not feasible.

Key Features

• Third-generation PIR image sensor with integrated image capture for alarm verification
• Wireless communication eliminates signal wiring to the control panel
• Passive infrared detection technology for reliable motion sensing
• Sold individually as a single unit

Compatibility

Designed as an OEM-style replacement or addition for compatible wireless security and alarm panel systems. Refer to the panel manufacturer documentation to confirm compatibility before installation.

Installation Notes

Installation should be performed by a licensed security or low-voltage technician familiar with intrusion detection systems and applicable local codes. Power down or disarm the security panel before enrolling or servicing any wireless sensor. Mount the sensor at the manufacturer-recommended height and angle to achieve the intended detection coverage. Avoid placement near heat sources or HVAC vents, as these can cause false triggers with PIR-based devices.
