A Quick Background

When it comes to video camera surveillance requirements, color and black and white CCTV security cameras are feasible security options. However, these two have different specialties. If you want to have color features, use color security cameras which is very effective in getting colors of criminals, vehicles or other possessions done during the crime. By getting the color information, it may hasten the flow of investigation. Color security cameras accurately produce colors because on the time of creating, IR cut filter is positioned on top of the imager. This let the cut filter to see only with the visible levels of spectrum. As a result, color surveillance cameras have less capability in creating functional images in low light setting.

On the contrary, black and white video camera surveillance setups don’t have an IR cut filter because they are intended to interpret color. Without the filter, B…W CCTV camera options can utilize other light frequencies like infrared. Infrared which come from a numerous sources, including the sun, fluorescent lights, incandescent lights and especially infrared illuminators. Consequently ,B…W surveillance cameras operates notably better in low light and some can see at light levels 0.0001 lux which is almost complete darkness. Other advantage of B…W video surveillance cameras is the ability to illuminate an area with IR. It provides the camera with sufficient lighting but gives natural darkness which can help in suspects’ arrest.

The Advantages of Day/Night Cameras

Either of the two Day/Night security cameras, color and black and white CCTV camera systems provides lots of distinctive features D/N video security cameras works the similar with color cameras at daytime , and switches to a B…W mode at nighttime employing the not fixed IR cut filter. When darkness comes, day/night cameras sense the lower light levels and involuntarily take out the IR cut filter, immediately switching to a more sensitive black and white mode.

Day/night surveillance cameras are offered in all forms to get the satisfaction needed in every establishment or home.Effective undercover operations gadgets like dome cameras, fixed cameras, bullet cameras and even in tiny board cameras are presented in many D/N technology forms. Those mentioned gadgets are very helpful since secret operations sometimes happen in diverse lighting circumstances. Numerous day/night CCTV cameras also present built in infrared illumination, which makes an excellent turn-key camera package.

D/N security cameras are frequently referred to as the true day/night cameras and and the most effective tool. On the other hand, digital day/night cameras (or electronic day/night cameras) also exist, which electronically regulate colors during the day, as a substitute of with an infrared filter. This gives the digital day/night cameras to send comparable benefits of true day/night cameras, although at a lower cost. Because of the innovation, without the filter, digital day/night technology can be adopted to be used in smaller and more modern gadgets, such as bullet cameras.

Regardless of the type of day/night camera you choose, I recommend considering the following areas to ensure you get the very best solution for your application:

1. Lux ratings – Unlike traditional cameras, day/night cameras typically have two lux ratings – one for the camera’s color mode, and one for its black and white mode. Understanding both will allow you to draw a true comparison between day/night and more familiar traditional CCTV cameras.

2. Lenses – If you are buying a fixed security day/night camera that requires a C- or CS-mount lens, be sure to get a CCTV camera lens that is rated for use with infrared light. IR ready camera lenses allow for the proper passage of IR light, the full use of the camera’s day/night capabilities, and of course, lower light performance.

3. S/N Ratio – There are many surveillance cameras in the market place with low lux ratings, but this does not always mean they will produce a good picture in low light. To ensure you get both, select a security camera with a signal-to-noise ratio of 48dB or higher

Video camera surveillance can be an proficient tool and is utilized in many industries. Employing video surveillance systems can have many very good results.
