While most regular television sets don’t have BNC jacks, it really is pretty common in many industries and there is no reason anyone should fear coming across it on security equipment. Most signals that have resonate frequencies below 3 GHz and voltages measuring below 500 volts should feel right at home being force through a BNC connector. Like the name suggests, it twists onto a plug and locks just like a bayonet would have on a firearm. It is an RF connector that can work with either 50 ohm or 75 ohm coaxial cable. BNC stands for Bayonet Neill-Concelman, though the term Bayonet Node Connector is sometimes uses as an alternative, albeit incorrect definition. This sort of knowledge can also be helpful for those who are working with bringing an older security camera installation up to date. To understand why there are so many different standards in the first place, it might be useful to come to terms with some of the history behind the different types of connectors. That doesn’t mean a VGA to BNC converter is necessarily the right piece of equipment to hook a BNC camera directly to a computer either, since many of them are only designed to allow people to use a computer monitor as a CCTV display unit. One couldn’t expect an analog CRT television monitor to accept VGA equipment, for instance. While it’s really helpful to allow security experts to capture video with a computer program, the VGA system isn’t at all useful with standard RF devices. However, the VGA system is designed to work with computers and it doesn’t involve itself with straight RF. Always take appropriate precautions and avoid electrical shocks or RF burns.įor instance, a female F connector and a male BNC plug could fit on the same adapter. Doing this incorrectly can cause serious damage to receiving equipment, and it can be dangerous to the person doing the installation work. Even if the connectors can be somehow jury-rigged together, it doesn’t necessarily mean that a television monitor is supposed to be receiving that particular type of signal. Of course, that doesn’t mean that a signal that a piece of equipment was not intended to receive should ever be sent to it. There’d be a loss of 1 dB or so, but it wouldn’t be major. If one needed to attach some other sort of coaxial connection to a security camera that used an F connector, they’d only need to find a small metal device that had an adapter for each connection on the ends.
Sometimes adapters are used to allow twin lead to work with F connectors as well.
F connectors are extremely common for regular consumer television equipment.
A great deal of camera equipment uses standard 75 ohm coaxial cable with F connectors. If one was working with video connections that used only RF connectors, or were working with part of a wireless transmission system or anything else that dealt directly with RF energy, connecting two different adapters together wouldn’t be all that difficult. A VGA to BNC converter might be the best way to accomplish this. However, many people would much rather have their security cameras connect to a computer monitor instead of a traditional CCTV system.
There are other devices like DVD burners and various types of hard disks that can also be installed to capture video. Surveillance operations are usually carried out on regular television monitors, and much of the video is recorded straight to an analog format like VHS. VGA to BNC co nverter boxes are an excellent way to bring security cameras into the modern era. VGA to BNC Converter Boxes: Computer Monitors can be CCTV Displays too
