Infrared Security Cameras: What You Need to Know
Crime is highest at night, and there’s a reason for that: a lack of light generally leads to a lack of security. Cameras need light to function, but that doesn’t mean it needs to be the same sort of light that we use.
Humans can’t see infrared light, but certain cameras can. This works out nicely when it’s night time and someone is trying to break into your business. They think they’re shaded in the cover of darkness, but your camera is picking up everything with perfect clarity.
Infrared cameras work best in keeping your business’s security covert. If you’re trying to monitor any after-hours employee actions, flooding your business with infrared light and planting a camera would be the best way to catch if they’re stealing.
This type of surveillance is best accomplished with a high quality day/night camera. More specifically, it should be a black and white camera. Color cameras don’t capture as high of quality at night, so black and white is best. One example of a camera with a great resolution is one with 690 TVL (or TV Lines). The resolution is the best.
After the camera is installed, you need to buy the actual infrared light. These usually go for about $200, and won’t make much of a dent in your power bill with its 12 volts of DC power. Some cameras come with a source of infrared light, which works just as well.
Before buying your new infrared camera, make sure your camera comes with Wide Dynamic Range, or WDR. WDR means that your camera knows how to change and adapt when different variations of lightness and darkness are available to the camera. For example, if the sun shines through your window and directly into the camera at sunset, your camera will adjust so it doesn’t block out the image. It allows the camera to take a more balanced, detailed image.
