Question

What outdoor security sensors are used for?

Answer 1

Oh well...

Outdoor security sensors detect intruders as soon as they enter a protected area and before they can gain access to people or valuable assets.



In a correctional environment, security sensors can be used to immediately detect prison escape attempts. A quality outdoor security system demonstrates a significant return on investment by reducing the risk of theft, damage or personal injury.



Outdoor sensors can be used either to complement indoor security sensors or as primary security in situations where indoor security is not feasible. Able to protect assets at both manned and unmanned sites, outdoor security sensors are a practical solution for remote sites where guards are not a viable alternative....
