Lack of well-planned camera coverage is one of the biggest problems in designing an effective video monitoring system. With a standard 3MP camera, you can see a dump truck lifting its dump bed and dumping its load at about 500-600 FT away – on a sunny day. However, with this camera resolution and from this distance, don’t expect to identify the truck driver, truck license plate, or company name printed in large lettering on the truck. But you will likely be able to identify the colour and type of truck from this distance.
Anything smaller than a dump truck, will pretty much not be possible to be identified at this distance with a 3MP camera which means you will not be able to see if a person with a pickup truck backed into a driveway and loaded up your material onto their truck.
Also, when designing your video monitoring system, pay special attention to ensure there are no blind spots within your site outside the coverage of your surveillance cameras. Cover all entries and exits to your site. Take into consideration the direction of the camera coverage as well as the distance. Don’t be tempted to cut costs by reducing the number of cameras because you can only monitor as far as the cameras can see on your site.
Keep in mind that surveillance cameras generate a lot of data that is very difficult to sift through manually. This is where you can use video analytics to make your video surveillance more efficient.
