Low light security

What is it important at low light condition?

It is very important from the viewpoint of crime prevention to design a security/surveillance camera system that functions at nighttime low light.
As a security/surveillance camera, it is important to take clear images even in low light conditions.
Panasonic security/surveillance cameras provide products that have the functions to solve this problem.

The illuminance of the object is a very important environmental factor.
Lux [lx] is used as an index representing this illuminance.
This indicates the amount of light per unit of time.
As a guide, the moonlight of the full moon is about 0.2 lux.


At low light, the security/surveillance camera uses infrared(IR) LEDs to illuminate the invisible infrared light.
In security/surveillance cameras equipped with most infrared LEDs, when the low light , it automatically shifts from color image to black-and-white image.
This is because infrared light has no color information (reason why human can not see the infrared light).


In New 360-degree cameras, even with the 0-lux state by providing built-in omnidirectional IR light, it enables visible objects.

Color Night Vision

However, color night vision security/serveillance cameras are equipped with image sensors with particularly high visible light sensitivity.
This makes it possible to reproduce colors by receiving more visible light even at low light.


Color night vision technology transforms a standard 1/3 inch sensor security camera into an effective low light capable security/surveillance  camera enabling it to produce a very high-quality color image-even in the most challenging lighting conditions.


Low Light Ready (4K-Camera)


The camera’s ultra-high 4K resolution allows it to capture color images in dim, low light conditions.
In even low light conditions, the camera can use its monochrome inversion function to switch to black-and-white images, and in zero-light conditions it can accurately display what is happening in front of it using infrared LED vision.
