Protecting your home or business is a round-the-clock affair. As such, having an alarm system as well as IP security camera system gives you peace of mind, knowing that you and your property are secure at all times.  Most IP Cameras are designed to work during the day and in environments that are properly lit.  On the other hand, some security cameras come with night vision capability, which enable them to capture images in the dark.    

Night Vision vs. IR CamerasWill My IP Cameras See In The Dark


There are two major types of security cameras that can capture images in the dark, namely, Infrared Cameras and Night Vision Cameras. IR cameras are fitted with LED illuminators surrounding the lens. When low lighting is detected, these IR illuminators light up to provide extra lighting to enable the cameras to operate. As such, IR cameras work perfectly in all lighting environments. Night Vision Cameras on the other hand, are more advanced and do not require any form of external lighting.

How Night Vision IP Cameras Work

1.    Image Enhancement

Image enhancement works by collecting and amplifying tiny amounts of light from the environment. Security cameras that use this night vision technology are fitted with an objective lens, which enables the camera to focus light particles on to a photocathode (negatively charged electrode). This process causes the light particles to accelerate and multiply to form a cloud. When this cloud of light electrons hits a phosphor screen, it glows, producing sufficient lighting to allow the camera to see in the dark.

Image enhancement works very well in both constant and low lighting conditions. As such, these IP Cameras can work during the day or at night without damaging the imaging detector. In addition, Night Vision Cameras using this technology can achieve a higher number of frames per second.
 
2.    Thermal Imaging

Thermal imaging cameras are fitted with a special lens which captures the infrared light being reflected from objects in the environment. The lens then focuses the IR light onto an element to produce a thermogram. The camera processes the thermogram to create video images.
