Cables & Splitter
Video signals are transmitted from the camera to the DVR via coax or RG*9 cable. Since power has to be ran to the camera as well, most installers use siamese cable which combines
the RG*9 and power cable in one. Siamese cable comes in premade lengths and spools of **0 or ***0 feet. Premade cables are convenient as they already have the BNC and Power connectors attached. For longer runs, installers prefer to use the spooled cable to customize their lengths.
BNC Connectors & Adapters
Any CCTV installation may require various BNC Connectors and Adapters. Connectors are components used to conduct and transfer signals from one cable or device to another. Adapters may be necessary to convert one type or gender of a connector to another.
Video Baluns
Which are impedance transformers that allow the transmittance of a video signal (*5 ohm) over cat 5 cable (**0 ohm). They are used in pairs to transform the impedance signal at one end and to transform it back at the other end. Mismatching impedance signals will cause delays in the signal transmittance resulting in a ghosting effect on the picture. Installers use baluns in areas where cat 5 is already ran making it more convenient or for transmitting signals over distances exceeding **0ft.
Power Supplies
All cameras require some sort of power source. Power Adapters or distribution box are used
in most installations. If installing 4 cameras or less, most installers will choose to use a power adapter and splitter whereas installations involving more cameras, they will use a power distribution box. When choosing a power adapter, be sure to get one that supports the voltage and amperage ratings for your cameras.
