USB security cameras are both affordable and easy to install which makes them an ideal choice for security and surveillance monitoring both in the home and at the office, especially if you are not interested in buying a full system. USB security cameras utilize a personal computer as part of the security system instead of a Digital Video Recorder or DVR.
“USB” is a computer acronym that stands for Universal Serial Bus. These cameras require a coaxial cable or similar cabling for transmitting their video images to a processor or personal computer. They do this via the personal computer’s USB plug.

Vandal proof security cameras are excellent for mounting in areas where the security digital video camera might otherwise be tampered with. Although they may not be able to sustain the injury inflicted upon them with something like a hard swing from a baseball bat, they are built with “vandal-proofing” technology in mind.
There are basically three types of digital video security and surveillance cameras: 1. The box camera; 2. The bullet camera; and, 3. The dome camera. THe box and the bullet cameras, mainly because of the way they are mounted, are fairly easy to tamper with. Especially the bullet camera, it can easily be persuaded to move on its mount thereby re-aiming the camera in a totally different direction and field of view.

It hasn’t been that long since we have had the advantage of using a security camera online. Before the proliferation of the Internet, security cameras at best, sent their images wirelessly using a radio frequency transmitter to repeaters (receiver/transmitters that would keep the signal viable and pass it along to its destination) or directly to a nearby monitoring company.
The inability to use a security camera online made monitoring somewhat tedious. Monitoring company locations were restricted as to their location in order that they remain close to the general area of their clients. Today, using a security camera online, the client’s camera system could be located in the state of Washington and the monitoring could be conducted in Florida.

Surveillance camera lens are slowly beginning to evolve with the technology that supports them. Before the digital age, a good majority of the surveillance cameras required that a lens be purchased for each camera. Presently, some cameras still work that way, but the vast majority has the lens built right into the camera. These lenses are often referred to as “board lenses.”
There are three major types of digital video camera based on their shape, the box type, the bullet type, and the dome type. Basically the bullet and dome type cameras come with a lens already built into the unit. This is often referred to as a board lens. The box camera however, almost always requires the purchase of a lens.

The closed circuit security camera has been used for decades. But when the digital world began to affect the digital video security and surveillance world, it opened up numerous new features never available before that made this type of system versatile, powerful, and simple and easy to use.
In addition, digital cameras became lighter, circuitry came on very small Integrated Circuit Chips (IC chips), and all of these things contributed to driving prices down so that systems were much more affordable for individuals and not just big corporations or the incredibly wealthy.
