How Light Guarding Works
A transmitter sends a focused beam of light to a receiver. If an object or person crosses the path, the beam breaks. The control panel registers the interruption and can activate alarms, log events, or block entry. Systems may use single or multiple beams for higher accuracy.
Why Light Guarding Matters
Light guarding provides a low-maintenance, non-contact way to monitor sensitive areas. It helps deter intrusions, reduce theft, and support compliance with safety regulations. For businesses, it can lower insurance costs and improve overall site security.
