Camera detectors are very useful tools for experienced investigators.  Although camera detectors would be most useful to private investigators, camera detectors can be used by a wide range of personnel in law enforcement and related fields.

The main purpose of camera detectors is self-explanatory given the name.  A client may want a sweep of a certain place to detect certain devices such as bugs and cameras.  Camera detectors scan the area for hidden or wireless devices that may be monitoring.  Depending on the setting of the device, the alert will be either LED, vibration, or a multitude of other alarms.
