CCTV cable, also known as coaxial cable or video cable, is the backbone that transmits video signals from your security cameras to the recording device (DVR or NVR). Choosing the right type of CCTV cable is crucial for ensuring clear, reliable video transmission in your CCTV system.
Here’s what to consider when selecting CCTV cable for your installation:
Type: There are two main types of CCTV cable commonly used:
Coaxial Cable (RG59): This is the traditional option, offering a good balance of affordability and performance for standard-definition and low-resolution HD CCTV systems.
Composite Video Cable: Less common but sometimes used for short runs, composite video cables are generally not recommended for CCTV due to their susceptibility to interference.
Length: Choose the appropriate cable length to connect your cameras to the recording device without excess. Excessively long cables can lead to signal degradation.
Quality: Opt for high-quality CCTV cable with good shielding to minimize interference from external sources like power lines or radio waves. This ensures clearer and more reliable video transmission.
Solid vs. Stranded Core: Solid core cables offer better signal quality over long distances, while stranded core cables are more flexible for easier installation in tight spaces.
Additional Features to Consider:
Weatherproofing: If your cameras are installed outdoors, choose a cable with a weatherproof jacket to protect it from rain, sun, and other elements.
Direct Burial: For underground cable runs, select a cable rated for direct burial to ensure proper protection.
By choosing the right CCTV cable, you can ensure optimal video quality and reliable transmission for your CCTV system.
Here’s a quick tip: Many pre-made CCTV cables come with BNC connectors on each end, making installation even easier. Just ensure the connector type matches your cameras and recording device.
