Surveillance at the speed of light
Eye safe invisible Infra-Red laser pulses are emitted from the sensor at 400 Hz. If an object appears in the line of sight it will generate reflections; which the sensor detects. IP connectivity and very low power.
The sensor analyses the reflected light and calculates the location of any object with high accuracy. Laser-Watch can detect up to 500m and up to 20 independent alarm zones can be programmed.
