Security & Safety Lighting Experts
In some applications, keeping the area dark may be a better approach. Examples of applications not to light might include pumping stations in isolated farm country, or isolated telephone relay enclosures. However, if criminals are likely to know that the area contains valuable materials, the absence of lighting may make the target more difficult to defend.
Thus, the decision to install a security lighting system depends on an understanding of the risk of criminal activity. If the risk of criminal activity is low, and the target relatively unknown to persons not familiar with the site, then providing security lighting may be counter-productive, especially in rural or isolated or otherwise dark areas. The risk of criminal attack is not the only concern for the designer. Safety lighting and the protection of persons are always of vital concern.
Security lighting for a controlled area should provide uniform illumination so that anyone moving in or around can be easily seen. Also, the security lighting design should provide sufficient illumination so that intrusion or attempted intrusion into the area can be detected, and any electronic surveillance devices such as security cameras, can operate within recommended tolerances.
Some examples of security and safety lighting for some common controlled sites include the following:
