Abstract
The video surveillance device with infrared LEDs has a casing and utilizes a partition element within the casing to place a camera assembly behind the partition element and the infrared LEDs in indentations on a front side of the partition element. A protective lens is interfaced directly with a washer on the front side of the partition element. As such, the light interference by the lens is effectively improved, while the external impact is buffered and absorbed largely by the washer, not directly on the camera assembly. In addition, the camera assembly is mounted on a downwardly concaved platform so that the camera assembly is able to slide along the curvature of the platform to aim at a specific direction. On the other hand, the LEDs are mounted on slant aluminum bases so that they could be aimed at different directions from that of the camera assembly.
