How do night vision security cameras work?

Thanks to our ever advancing technologies, night vision has become a standard feature for most security cameras. Night vision security cameras allow us to keep a close watch on our homes or businesses around the clock. But how can these security cameras is near to total darkness? There are three different methods: low-light, thermal imaging, and infrared illumination.


Low-light security cameras use image intensifiers which make the most of a faint light source. Because they are attuned to work with limited light sources, the pictures they produce in these settings are excellent. Some low-light cameras can even identify persons. Of the different methods employed, this seems to be the most affordable and is commonly used among homeowners.

Thermal Imaging

Thermal imaging technology uses temperature instead of light sources to produce images. This is based on the principle that objects radiate infrared due to temperature. This infrared energy, which is intensified with higher temperatures, creates the thermal image. When objects are cold, the image produced is black, whereas hot objects produce white images. Some thermal cameras can produce color images, and can even detect objects from far distances. Unfortunately, thermal imaging has yet to gain mainstream popularity, but is rather useful in other settings.


Home security cameras utilize infrared illumination and motion detection for effective night surveillance. When the security camera detects motion, the infrared illumination lights up and captures images. Because the infrared is only triggered by motion, this saves power. LED lights enhance performance to produce excellent black and white videos and images. Infrared security cameras are often used for outdoor home surveillance.

How Do Night Vision Cameras Work?

Using night vision security cameras within your security system can greatly benefit your safety. Night vision security cameras utilize infrared light-emitting diodes (LEDs) to produce infrared light not visible to the naked eye. These IR LEDs illuminate low light or no light environments allowing cameras to capture footage under less than ideal circumstances. These cameras allow you to keep an eye on your property at all hours.

During the day, when ample light is available, the infrared security cameras record in full color. Once evening falls and light sources are diminished, the IR LEDs begin to work and the cameras record in black and white. Switching to black and white recording helps to preserve image quality, providing excellent footage around the clock.

Night vision and infrared LEDs are available with most security cameras styles. Choose the camera style based on where you’ll be placing your security cameras. For indoor settings, dome cameras or small bullet cameras may be best, so that they can blend into the décor. For outdoor settings, you’ll want to be sure that your security cameras are weatherproof and vandal proof, or purchase proper housing to protect your cameras. Long range bullet cameras or PTZ cameras may be a better choice for outdoor locations, depending on the area you would like to monitor. Whether installed indoors or outdoors, night vision is a helpful feature for your security cameras.

Not only are you enabling your security system to work 24/7, you are potentially helping to stop or solve crimes faster. Security cameras act as deterrents, but many may think the cameras don’t work in darkness. With night vision security cameras, you now have footage of an overnight crime that could potentially help identify and catch the criminal.

Rest a little easier at night by adding infrared or night vision security cameras to your overall security system.
