1 Introduction
1.1 Overview
With its built-in 2-MP HD camera and CMOS image sensor, wireless PIR–Camera detects intrusions
and captures high-definition snapshots. It is a wireless passive infrared detector that sends
snapshots through the Wi-Fi and Ethernet connection to your phone and ARC (alarm center), for the
causes of intrusions to be effectively identified.
The camera is also uniquely designed to only take snapshots when an intrusion occurs, eliminating
the need to install cameras to constantly monitor scenes. Built to keep your family and business safe,
the entire data transmission process is encrypted and the camera does not actively obtain your
private information.
1.2 Technical Specifications
