Security cameras for many homeowners and businesses are merely a part of ownership today. In fact, they are so common many simply take them for granted. However, as common as they might be, any camera system must be chosen wisely. The reality is, that some people may assume that a camera prominently displayed, will solve their security problems. Subsequently, cameras are installed and forgotten about. Practically speaking, any camera, regardless of quality and capabilities, will provide some level of security. When cameras are present, they tend to restrain people, and can prevent certain crimes.

If you are a school bus driver and you have bus surveillance cameras, you know what a blessing they truly are. Equipment that is visible (whether it’s actually working or off) has an incredibly large deterrence factor. This doesn’t apply to just school buses but all kinds of buses and public transportation.
What is different on bus surveillance cameras than on regular surveillance cameras? First, the whole system is a bit different. Here is why.
Like any other Digital Video Reorder (DVR), a 16 channel digital video recorder uses a computer hard drive to compress and store video images using various compression techniques. (Incidentally, “16 channel” means the DVR can work with up to 16 cameras simultaneously.)
The compression techniques include JPEG, MPEG, Wavelet and a host of proprietary methods. Images can be stored at a rate of just a few frames per second (fps) to as many as 400fps depending on the software features offered by the manufacturer. This is the latest in CCTV DVR Video Surveillance technology, eliminating the use of tape recorders.
