Outdoor Motion Detection Alarm System

Solar Signals is a leader in designing and manufacturing remote site power systems with over 20 years of experience in designing systems specifically for the harsh Canadian environments.   This experience, combined with our design team from the transportation and security industry sectors has driven the development of the Extreme Outdoor Motion Detection Alarm System.  

Based on one of our standard solar power systems that is specifically sized for the load and installation location and incorporating our standard multichannel signalling radios we have added an industry leading Passive Infrared (PIR) system to detect human sized thermal targets moving across a very narrow field of view.

Protect and detect

The PIRs have a human sized target range of 150m (500’) with only a 3m (11’) wide detection zone at that range.  To reduce false alarms, the PIRs have variable sensitivities through the length of the field of view with sensitivity reducing as the object gets closer to the sensor.  In addition, the PIRs have two parallel detection zones throughout the length of the detection field of view.  The thermal source it detects has to move across from one to the other before an alarm is generated.   

To protect against vandalism or other attempts at defeating the unit alarms are generated if someone tries to rotate it away from where it is directed, blind it by covering the sensors or removing it from the mounting pole.  They also have a specific sensor designed to look below and behind themselves so there are no blind spots at the bottom of the pole as you often see with camera systems.

Each detection pole comes with two PIRs and can cover up to 300m (1,000’).  Each PIR drives a separate radio signal to advise which zone (PIR) has detected an alarm event.   The radio receiver in the base station has a range of up to 3km with an included dipole antenna and provides dry contact outputs for each alarm zone.  As with all Solar Signals systems, these units will operate in any weather and in temperatures from -40C (-40F) to +40C (105F)
