Abstract
A security system for an in-vehicle digital video recorder, comprising a sensor and a processing resource, the security system operative in: a first mode in which the sensor is operative at a first resolution; and a second mode in which the sensor is operative at a second resolution higher than the first resolution; the security system operative to receive signals from the sensor; wherein in the first mode the security system invokes the second mode responsive to a sensor signal exceeding a threshold value; and wherein in the second mode the processing resource monitors to determine if a security threat criterion is satisfied based on a received sensor signal.
