It wasn’t that long ago, that the idea of capturing License Plates and storing them in a database meant spending what most companies would consider to be their entire security budget. Over the past 10 years, the use of these systems has increased dramatically and as technology has improved, the costs of having such a system have come down also.

Wide Dynamic Range cameras have been around for a little while now but although a lot of people have heard of Wide Dynamic, nowhere near as many have actually used this technology.
Firstly, for those of you who do not know what Wide Dynamic Range (or WDR for short) means, here’s a brief explanation…….
Wide Dynamic Range is a technology which allows the camera to cope with extreme lighting levels. This can be very low light but is often used to cope with extremely bright areas such as the sun shining through a glass door or window.
A typical example of where Wide Dynamic Cameras could be used would be where a camera is pointing towards a set of windows. When the sun shines through the windows this can wash out the image and make it almost impossible to view anyone either standing in front of or behind the glass.
As you can see in the example below with WDR technology, the figures in front of the glass and the scene through the glass are both visible.
