Infiray thermal cameras are useful devices that help us keep our offices and home safe. The devices record activities in the area in which they are installed and help us remain away from unauthorised presence. One of their biggest benefits is that they keep us safe at night. The latest technology has made it possible for us to see things that happen at night in our homes. However, in certain cases, you may face problems with your night vision devices which should be solved quickly to continue enjoying the benefits of your device.
No video or image at night
This is one of the most common problems with night vision devices. To solve this issue, you should check the camera and ensure all the connections are secure. You should also ensure that your device has power. You need to ensure that the infrared light is on. This indicates that enough power is going through.
You must understand that the camera may not always function in the range that it claims so do not rely on the specifications. Shorten the range of your device to get the full benefits of your camera. You can try standing close to your camera and see whether your camera shows anything.
White screen or white areas on the screen
This is another common issue with night vision equipment. The reason for this is that the infrared light is reflected in the camera lens. This is the main cause if the angle of the view is extra wide.
You can solve this problem by ensuring you have the visor in line with the back of your camera body. The visor is the part that protects the lens from reflections or direct light. This can provide the lens with the necessary shade and reduce white lights and other distractions.
Deterioration of images at night
At night, you can experience the problem of the general deterioration of the images as far as surveillance or CCTV cameras are connected. This happens when the infrared switches on your camera draw more current than required. But if the power isn’t that powerful enough, the extra current will lead to some issues.
To solve this issue, you should ensure that you don’t exceed the recommended or suggested cable run length and the cable is long enough. When you have a long cable, it will cause connection problems and this may affect image quality.
Moving spots
You can experience moving spots in your camera which may look like spider webs. This is more noticeable during fog-type weather where water droplets suspended in the air cause a reflection of the infrared light. The warm current in the air will lead to particles rising and dropping and these appear as moving spots in your camera.
You can avoid this by covering your camera with a hood or visor and avoiding placing your camera in areas with a lot of dust. There are a lot of covers you can buy for your InfiRay thermal camera to prevent this problem.
