VST-852Pro-Ultra NT PIR Motion Sensor Camera 

 

Introduction 

VST-852Po-Ultra is a ZigBee passive infrared (PIR) motion sensor camera with pet-immune function. It 
is capable of sending wireless signals and captured images (picture quality of up to 640 x 480 pixels) to 
the coordinator in the ZigBee network upon movement detection. 
The PIR Camera is designed to give a typical detection range of 12 meters when mounted at 2 meters 
above ground. It has a pet-immune range of 7 meters and will not trigger false alarm from you 
household pets within this distance.   
The PIR Camera utilizes ZigBee technology for wireless signal transmission. ZigBee is a wireless 
communication protocol that is reliable and has low power consumption and high transmission efficiency. 
Based on the IEEE802.15.4 standard, ZigBee allows a large amount of devices to be included in a 
network and coordinated for data exchange and signal transmission 
The PIR Camera serves as an end device in the ZigBee network. It can be included in the ZigBee 
network to transmit signal upon activation, but cannot permit any other ZigBee device to join the 
network through the PIR.   

 

Parts Identification 

1. Flash 

LED 

The Flash LED delivers sufficient light for image capture under low 
lighting condition. 
Both the Flash LED and the Blue LED will flash once when the 
Function Button is pressed for 10 seconds to indicate the PIR 
Camera has been reset. 

2. IR 

Sensor 

The sensor is intended to detect moving objects. 

3.  PIR Camera Lens 

4.  Blue LED/Function Button 

LED Indication:

 

The Blue LED lights up in the following conditions: 

- The Blue LED flash once every 20 minutes 

The PIR Camera has lost connection to its current ZigBee 
network. 

- The Blue LED lights up for 30 seconds: 

The PIR Camera is warming up when fault(s) exists in the PIR 
Camera. 

- The Blue LED flashes twice quickly: 

The PIR Camera has successfully joined a ZigBee network 
after factory reset. 

- The Blue LED lights up for 2 seconds under normal operation: 

The PIR Camera has detected a movement when fault(s) 
exists in the PIR Camera. 

- The Blue LED flashes rapidly 

PIR Camera is transmitting pictures to the coordinator of the 
ZigBee network when fault(s) exists in the PIR Camera. 

- The Blue LED and Flash LED flash once 

PIR Camera has been reset. 

Function Button Usage: 

- Press the button once to send a supervision signal. 
- To reset the PIR Camera: 

Press and hold the button for 10 seconds. Release the button 
when both the Flash LED and the Blue LED flash once
