One of the considerations when designing your business security system is the ability to function both during the day and at night. It is very easy to deploy your surveillance system in environments with constant lighting. However, if the lighting conditions are poor or keep fluctuating, you will need to come up with measures to enable your cameras to record at all times.
How to get your security cameras to record at night
1. Improve the lighting conditions
The regular security cameras are unable to record at night because of the poor lighting. As such, improving the lighting conditions will enable these cameras to function just as they would during the day. The type of lighting to use with your business security system will depend on the specific application. For instance, you can install powerful LED lights or fluorescent tubes to light up the area under surveillance. For covert surveillance applications however, you should use Infrared illuminators to provide invisible lighting.
2. True Day/Night Cameras
These security cameras are designed to operate in both normal and poor lighting conditions without requiring any additional lighting. The cameras are fitted with a mechanical infrared cut filter removable (ICR), which blocks out the Infrared wavelengths during the day. As such, only visible light is allowed to pass through, thus improving the image quality. At night, the IR cut filter is removed to allow the Infrared light to pass, thus enables the cameras to record in low light.
On the other hand, there are Digital Day/Night cameras which don't use the IR cut filter. Instead, they have an electronic adjustment mechanism that digitally switches between color and black and white modes to allow the cameras to record during the day and at night respectively.
3. Infrared Cameras
These security cameras come with inbuilt infrared illuminators surrounding the lens. In normal lighting conditions, these IR LEDs are usually off. However, when night falls or poor lighting is detected, the IR LEDs light up and illuminate the area under coverage, thus enabling the security cameras to record.
