Abstract

A surveillance apparatus and an associated surveillance method are provided. The surveillance apparatus includes a video recorder, an infrared sensor and a motion detector. The surveillance method includes following steps. First, a video stream corresponding to a surveillance region is captured. Then, an infrared status of an infrared sensing region is sensed to selectively generate a trigger signal. The infrared sensing region and the surveillance region are partially overlapped. A motion detection signal according to the video stream is selectively generated. Whether a moving object is detected is determined according to the trigger signal and the motion detection signal.

Claims

1. A surveillance apparatus, comprising:

a video recorder, for capturing a video stream corresponding to a surveillance region;

an infrared sensor, for selectively generating a trigger signal in response to a status of an infrared sensing region, wherein the infrared sensing region is partially overlapped with the surveillance region; and

a motion detector, for selectively generating a motion detection signal according to the video stream,

wherein the surveillance apparatus determines whether a moving object is detected according to the trigger signal and the motion detection signal.

2. The surveillance apparatus of claim 1, wherein the infrared sensor is a passive infrared (PIR) sensor.

3. The surveillance apparatus of claim 1, further comprising:

a controller, electrically connected to the infrared sensor and the motion detector, for generating an alert signal when the trigger signal and the motion detection signal satisfy a predetermined condition.

4. The surveillance apparatus of claim 3, wherein the video recorder dynamically adjusts recording quality of the video stream according to generation of the alert signal.

5. A surveillance method, comprising steps of:

capturing a video stream corresponding to a surveillance region;

sensing a status of an infrared sensing region to selectively generate a trigger signal, wherein the infrared sensing region is partially overlapped with the surveillance region;

selectively generating a motion detection signal according to the video stream; and

determining whether a moving object is detected according to the trigger signal and the motion detection signal.

6. The surveillance method of claim 5, wherein the step of determining whether the moving object is detected according to the trigger signal and the motion detection signal comprises steps of:

determining whether the trigger signal and the motion detection signal satisfy a predetermined condition; and

dynamically adjusting recording quality of the video stream according to whether the predetermined condition is satisfied.
