The geomery of camera lens 61 " and lens fixing bracket 5 " can be adjusted suitably.
In one embodiment, multiple lenticular bodies are provided at circumferentially spaced around the form body.Such as it is double in figure
82 " number of the second light filling through-hole on color translucent cover pressing plate 8 " is two, be separately positioned on the second form through-hole 81 " top and
The center of lower part.Other number and location are can also be, as long as light filling effect can be played preferably.
The course of work of video camera provided by the utility model is as follows：
After video camera electrifying startup, temperature sensor perceptron chamber internal temperature, if temperature is relatively low, temperature-adjusting device 4 "
It starts to work, camera lens is begun to warm up, wait for temperature rise to preset temperature, camera lens 61 " is started to work, object reflection to be imaged
Light enters camera lens, is handled by a series of software and hardwares, ultimately forms image.Wherein, when ambient is weaker, light filling element is opened
Beginning work, emit beam (infrared light or white light), illuminating objects, after repeat above-mentioned camera shooting process.
The utility model further includes a kind of monitoring system, and the monitoring system includes the camera shooting as described in the various embodiments described above
Machine.The video camera may include visual sensor or heat sensor, visual pattern or thermal image for capturing monitoring scene, right
Waterproof requirement is higher.
It is last it is to be noted that：Above example is only to illustrate the technical solution of the utility model, rather than limits it
System.It will be understood by those of ordinary skill in the art that：Can with technical scheme described in the above embodiments is modified, or
Person's equivalent replacement of some of the technical features；These modifications or replacements do not make the essence of corresponding technical solution de-
Spirit and scope from various embodiments of the utility model technical solution.
