Around the Clock Surveillance with Day/Night Network Cameras

Day/night network cameras provide around the clock surveillance in environments where artificial light is restricted. The specialized IP cameras are equipped with technology to automatically adjust to handle light-challenged situations, providing high-caliber images 24/7.

Around the Clock Surveillance

Some IP cameras will claim to offer superior low-light performance, but true day/night network cameras will automatically switch to a night mode when the light level drops below a certain point. Typically day/night cameras will capture color images throughout the day and switch to a black-and-white mode at night making use of near-infrared (IR) light.

Removable IR-Cut Filters

During the day when IR light hits the image sensor of a day/night camera colors can become distorted. Because of this, day/night cameras are equipped with a removable IR-cut filter to filter the IR light so that it doesn’t warp the colors of images captured during the day time. When the camera switches back to night mode the IR-cut filter is removed allowing the camera’s light sensitivity to reach levels as low as 0.001 lux.

IR Illuminators

IR illuminators can be used to further increase a day/night camera’s capability to capture detailed video in challenging lighting conditions. Some day/night cameras will have built-in IR illuminators and others are compatible with IR illuminator models that are sold separately. IR illuminators provide additional light in surveillance applications where the surrounding lighting environment isn’t ideal for high-quality video monitoring and recording.
