The newly bought Sirait ST-685IR surveillance camera has some problems that need help:

1. The infrared lamp will glow when working, and it can be seen by naked eyes. Maybe you installed it too high or too far. You can see the infrared light shining near the camera at night, but you can't see it without looking carefully.

2. The infrared camera has the function of automatically changing the color to black. Automatically switch colors when the outside light is strong, and automatically switch black and white when the light is dark. In the case of street lamps, there are external fill lights, so color pictures are displayed.

3. The one you mentioned can't be found online. It should be changed for the sake of price transparency. Siraite is a brand in Shenzhen. Its full name is Shenzhen Hecheng Kyushu Siraite Electronic Technology Co., Ltd., and there is no company website. There are many cameras in Shenzhen at present. Judging from the recruitment information of their company, it is a sales-oriented company without its own research and development strength, and its products should be mainly OEM. It is recommended to choose the products of regular manufacturers.

4, this situation is normal, the bigger the lens, the farther you look, the smaller the scope; The smaller the lens, the closer you look and the wider the range. In your case, try changing the lens of 16mm, or changing the installation position closer to the car.
