When beginning your search for wholesale security distributors, you may notice that there is a seemingly endless pool of surveillance equipment suppliers. If you are new to the world of CCTV (a term we will define below), then it can be quite difficult to sift through all the technical jargon. TechVision has been in the security distribution game for a long time and knows that the more informed a customer is, the better their buying and operating experience will be. We’ve put together this cheat sheet for those who are just dipping their toes into surveillance technology.
Know The Lingo
The security business has a language all its own with many acronyms and shorthands. By nailing down some vocabulary, you’ll be able to understand the whole process a bit easier. Luckily, once these terms are demystified, you’ll realize that surveillance equipment usually falls into one of a few categories and the nomenclature is actually pretty intuitive. Here are the CCTV terms we think are essential for you to know.
CCTV: Ok, first to make good on our promise. CCTV stands for Closed-Circuit Television. This is what a surveillance network is at its core. Closed-circuit simply means that the system is not broadcasting a signal, and is not receiving outside broadcasts. This is different from your traditional television which is constantly receiving information over the air or through cable. Essentially, CCTV is a self-contained tv “studio” that shoots, processes, and plays its own footage. This keeps your surveillance footage secure as it never leaves this enclosed loop. Your cameras, recorders, networking, analytics equipment, and monitors will make up your CCTV system.
Analog: Analog CCTV systems include analog cameras that are connected to DVRs using coaxial cable. This is an older style of CCTV tech with generally lower video quality than other options but still has plenty of practical uses today.
HDCVI/HDTVI: two pretty analogous technologies developed by different companies. Both provide superior HD quality images when compared to traditional analog cameras. These are also wired using coaxial cable and connected to a capable DVR. This means that HDCVI or HDTVI cameras are easy to incorporate into an existing analog system without completely overhauling all of your wirings.
DVR: DVR stands for Digital Video Recorder. There are many types of DVRs that are capable of supporting different types of cameras. The job of a DVR is to store and digitally process the information from your cameras.
Coaxial Cable: this is the cable used to wire analog, HDCVI, and HDTVI CCTV networks to transfer video from camera to recorder. You’ll also see it referred to as just coax. some coax cable is called Siamese cable as it supplies both video capabilities as well as power.
IP: IP or Internet Protocol systems are the most diverse and advanced category of CCTV tech. Unlike previously mentioned cameras, an IP camera has its own IP address and process videos itself before transferring them to an NVR via an internet connection.
NVR: NVR stands for Network Video Recorder. It stores IP captured images and allows for remote viewing of your security cameras. NVRs and IP cameras need a stable network connection which is usually accomplished with ethernet cable.
Ethernet: Ethernet cable is used to connect your IP elements to each other and to the internet.
PoE: Some NVRs and IP cameras have PoE, or Power over Ethernet, options. This means that ethernet supplies the system’s power as well. This makes wiring much more streamlined.
So now you are primed on some of the most important CCTV terms. Of course, this is only a starting point. If you have any further questions, TechVision has a whole library of CCTV related help articles.
Know Your Needs
There are many factors that go into determining what CCTV setup is best for you. Some DVRs and NVRs are only capable of supporting 4 cameras while other options boast 128 camera aptness! You’ll also need to choose what type of system is best for you based on things like budget and picture quality/ distance needs. Because there are so many variables to consider, we recommend you speak to our dedicate sales team. They are security pros with years of experience and knowledge in designing custom security solutions.
