Learn More About Wide Dynamic Range Dome Cameras
To understand the concept of how wide dynamic range works with security cameras, you must first understand what is going on in your environment.
Take a look around your indoor application. If there is a room where natural or artificial lights are constantly changing, then you are going to have
some issues where the room is too bright or too dark. You will also find that during the most unusual times, like when it is too bright or too dark in a
room you want to monitor, you will have an issue, theft, accident, dangerous situation, or that one event you wanted to capture on camera. This is why
wide dynamic range is in high demand for indoor applications that have windows, glass doors, pretty much any small business setting where there is
a flow of traffic constantly during business hours.
Wide dynamic range was invented mainly by Fuji initially, they brought it to their "SR" version of their SUPER CCD cameras and soon after other camera
OEM manufactures soon followed. However there are two main solutions that WDR dome cameras use. One there is multi-frame imaging, where the
dome camera captures more than one frame of the field of view. Each frame in this technique has a different dynamic range. The camera will take both
frames and combine both dynamic ranges to produce one wide dynamic range. This technique is used for still images. The second technique is more for
security cameras. This process uses non linear sensors, usually complex algorithms, where the sensor sense the different levels of illumination and thus
enables the capture of just one image to make for a wide dynamic range. In this situation the camera is always thinking and digitally enhancing the exposure
of the frame or image to render the most optimal video quality.
Restaurants With Big Windows Need Cameras With Wide Dynamic Range
If you have a few security cameras indoors on your dining room floor or near doors that constantly open and close, then you are going to need dome
cameras with wide dynamic range technology. This technology will aid you in the ability for it to constantly re-evaluate and produce the most optimal
video quality. There are times during service where the windows have immense light in certain windows and others that almost no extra light and thus
a darker shadow cast over that area. The problem will arise where you cannot see what is going on because of this problem and you will have video loss.
Do not just buy any old camera and put it up. You must know the environment of your application first, before you can know what you need. However,
not all applications are easy to troubleshoot from the start without some trail and error. If you are a restaurant manager or owner and you need a solution,
use WDR dome cameras and you will solve the issues of not having a constant, bright, high resolution video shot when you need critical information. Other
businesses can uses these cameras too. Any area with big windows or solid glass doors, you will want to use these cameras during your operational times
indoors or outdoors. If you have any questions about how it all works still, call our 800 line and speak to a CCTV consultant today.
