Capturing video footage with your digital video camera system is great, but there may be times when audio is also needed. In this case you will more than likely want to have some good surveillance camera microphones.
Many of Security Camera King’s digital video security cameras come with an on-board surveillance camera microphone to record audio. Some of the more frequent applications of audio are using the camera at entrances and exits as a door guard, gate keeper, or other special applications.

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.

If you would rather use Cat5E instead of RG59 cable, it’s likely that somewhere along the way you will need a passive video balun. Security Camera King carries a full line of baluns both active and passive. Passive video baluns help prevent the degradation of the radio frequency signal over cable.
A balun is really a specific type of transformer that can convert electrical signals that are balance about ground (also known as differential) to signals that are unbalanced (single ended) and vice versa. The name “Balun” comes from two words, BAL(ance) and UN(balance).

Digital video security cameras come in all shapes and sizes and with different degrees of resolution, often using the phrase “TVL Camera” such as a 550 TVL Camera. What does TVL mean and how does it relate to digital video security cameras? We’ll answer that question and more in the following article.
First, It will make things much easier to understand if you know a little security camera industry history. Full security camera systems have been around for several years now, however not until relatively recently have the systems been based on binary (digital) data instead of its older analog data.
