Sistem CCTV dengan kabel akan memberikan kualitas gambar terbaik dengan nol gangguan. Kabel CCTV umumnya menggunakan colokan BNC yang dapat dihubungkan langsung ke DVR atau ke TV menggunakan adaptor. Namun sistem pengawasan kamera CCTV dengan kabel akan lebih lama proses instalasinya dan tidak dapat dengan mudah dipindahkan ke lokasi lain. Sistem kamera keamanan wireless (nirkabel) menawarkan jangkauan transmisi hingga 200 meter. Meskipun lebih mudah instalasinya namun kelemahannya adalah terkadang sinyal dapat menderita gangguan dari sinyal wireless lainnya seperti jaringan WiFi.
Kabel CCTV RG59 & RG6
RG59 cable is the industry standard for transmitting video signal. The term RG59 is the type of gauge (the thickness) the cable is. The goal is to measure the power of what you are trying to transmit and make sure you have the right gauge. Most security cameras can transmit signal well over a RG59 or RG6. RG6 is a thicker gauge cable. You can use these cable for surveillance cameras, you will just have to find and industry standard RG6 connector that adapts well with a female video port. So if you are looking for cable, take a look at RG59 video cable. It is the best for most CCTV applications and is shielded from most video interference.
CAT5 & Video Baluns
We can also use CAT5 to transmit video signal. There are many benefits to using CAT5 cable to transimit video. Most people that get into designing CCTV systems are a amateurs and this solution works well with anyone who does not look forward to fabricating RG59 cable. If you want to connect this kind of cable to a female BNC connector we will use special kind of adapter. In the last years, video baluns have been the answer to transmitting video. One of the main advantages of CAT5 has over RG59 is the ability to transmit video up to 1500-5000 feet. The more simple the connector is the shorter the distance you can transmit video over.
There are even video baluns that can transmit power, video, and data in one shot. It really is a simple plug and play setup for CCTV applications. There is no sacrifice in video quality either. The only draw back to using CAT5 cable is that you can run the cable across other electronic device, electrical components, U.V. lighting or any other devices that could cause video or signal interference. The cable is not very well shielded and we will have to keep that in mind when blue-printing your CCTV installation. Other than that, this is becoming end-users and installers first choice for CCTV video transmission.
