What Makes RG59 Ideal for CCTV:
1. Built to Combat Interference:
-
Centre Conductor: Solid bare copper for excellent signal conduction.
-
Dielectric: Foam polyethylene insulation for stable signal speed.
-
Shield: 95% bare copper braid to block out electrical "noise."
-
Jacket: UV-resistant PVC for durability.
This layered construction ensures the video signal from your camera arrives at the DVR clearly, without static or distortion from nearby electrical sources.
2. Perfect for Analog Cameras:
Unlike network (IP) cameras that use Ethernet cable, traditional analog CCTV cameras are designed to use this exact type of coaxial cable with BNC connectors. It's a plug-and-play match.
What You Can Use This Cable For:
1. Direct Camera to DVR Connection:
The primary use. Run the cable from each camera directly to your Digital Video Recorder (DVR). You will need two BNC connectors for each cable run.
2. Using with Video Baluns (For Ultimate Flexibility):
You can use this coaxial cable with video baluns. This lets you convert the signal to run over cheap Ethernet (Cat5/6) cable for part of the run, which can be easier to pull through walls or over very long distances.
3. Extending Existing Systems:
Easily replace a faulty cable or add a new camera to an old, reliable analog system.
What You'll Need to Finish the Job:
-
BNC Connectors: To plug the cable into cameras and the DVR. Compression-type connectors are recommended for the best, most weatherproof seal.
-
A BNC Compression/Crimp Tool: To attach the connectors securely.
-
A Coaxial Cable Stripper (Highly Recommended): Makes preparing the cable ends quick, easy, and precise.
-
Optional: Siamese Cable: If your cameras don't have separate power, you may want RG59 "Siamese" cable, which has a power pair built-in.
Installation Tips:
-
Plan Your Route: Avoid running the cable parallel to mains electrical cables. If you must cross them, do so at a 90-degree angle to minimize interference.
-
Use Drip Loops: When entering a building, create a "U" shape loop below the entry point to prevent water from running down the cable and inside.
-
Secure Gently: Use cable clips or staples designed for coaxial cable. Do not crush or pierce the cable.
-
Test Before Finalising: After running the cable but before hiding it permanently, connect it and check the video feed is clear.

Frequently Asked Questions:
Q: Will this work with my 8-camera DVR system?
A: Yes. A 100m roll is perfect for a standard system. Measure the distance from your DVR to each camera location. You'll cut one cable per camera from this single roll.
Q: Can I use this for digital or IP cameras?
A: No. IP cameras transmit data and require Ethernet (Cat5e/6) cable. This RG59 cable is for traditional analog CCTV cameras only.
Q: Is this suitable for direct burial in the ground?
A: This standard version is not. The jacket is UV-resistant but not designed for direct soil contact. For burial, you need a direct burial or flooded coaxial cable with a special protective jacket.
Q: How do I connect it to BNC plugs?
A: You need to attach a BNC connector to each end. Compression BNC connectors (which require a special compression tool) provide the most reliable and weatherproof connection, especially for outdoor use.
The Bottom Line:
For a reliable, clear, and cost-effective analog CCTV system, RG59 coaxial cable remains the undisputed champion. This 100m roll gives you the high-quality materials and professional shielding needed for a surveillance system you can count on, without overcomplicating the installation.
Choose the cable designed for the job. Ensure clear footage and a robust installation with trusted RG59 coaxial cable.
