Overview
The document describes the VX-402 series, a range of outdoor detectors designed for reliable short-range detection, ideal for event-driven CCTV applications. The series includes models with voice recording capabilities (VX-402REC) and battery-operated options (VX-402R).

Specifications
The VX-402 series features two detection zones for enhanced stability, with adjustable zones in 15-degree steps. The detection method is passive infrared, covering a 12m (40ft) range at a 90-degree angle with 14 zones. The mounting height is between 0.8 to 1.2 meters, and the detectable speed ranges from 0.3 to 1.5 meters per second. The units are weatherproof (IP54) and operate in temperatures from -20 to +50 degrees Celsius.

Power and Installation
The VX-402R model is battery-operated, supporting 3-9V DC alkaline or lithium batteries, with a low current draw for extended battery life. Installation is simple and wire-free, suitable for wall or pole mounting.

Voice Recording and Playback (VX-402REC)
The VX-402REC model allows for recording messages in any language, with up to two messages of eight seconds each. These messages can be played back in various sequences, such as day/night or arm/disarm modes, providing flexibility for different applications like intruder prevention or customer greetings.

Advanced Features
The series includes advanced features like temperature compensation to maintain sensitivity in varying temperatures, double conductive shielding to reduce false alarms from light and RFI sources, and a size judging function to minimize false alarms from small animals.

Applications
The VX-402 series is suitable for various applications, including intruder prevention, safety warnings, and customer greetings. It can be integrated with other detection devices for enhanced functionality and reliability without needing a control panel.

Conclusion
The VX-402 series offers a versatile and reliable solution for outdoor detection needs, with options for voice recording and battery operation, making it suitable for a wide range of security applications.
