Operation in Low Light Conditions
Most security cameras are installed outside and as sure as day follows night, night follows day. During the day, the cameras will see great color images. At night, depending on the type of camera one of two things will happen.
Cameras with IR Illumination (most common)
When the light level falls the infra red LEDs illuminate and start to provide additional light to help the camera. This will actually happen before the camera requires it to ensure it’s ready when needed. When the camera senses the light levels are just too low it will switch over to use this infra red illumination. This type of assisted viewing works all the way down to complete darkness.
There are different types of IR LEDs that have different strengths and weaknesses. In each of our cameras we select the best type of LED for the camera’s intended purpose.
We do stock an IR illuminator if you find there are certain areas of the image that need a little extra lighting at night.
Cameras without IR Illumination
Some cameras do not have on-board infra red illumination. Our cameras do feature sensitive electronics that produce a good image in low light. Unfortunately, however if there is no light you get no image. These cameras work great for use inside in situations where you know the lights will always be on when the building is in use.
Can I help the Camera Out?
Yes, you can help out. Security cameras fundamentally work by sensing light. Providing other light sources can help the camera out. Flood lights that either stay on all night or are triggered by movement sensors are great. Not only does motion triggered lighting help attract attention but it also provides additional light for the camera.
