How to find the right Surveillance Camera Cables AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Surveillance Camera Cables
- PoE run length
- Ethernet/PoE runs are limited to 100 m (328 ft) per segment. Beyond that, use a PoE extender or switch. Past this distance, both data and power become unreliable.
- Cat5e vs Cat6
- Cat5e solid copper is sufficient for camera PoE. Cat6 adds margin but is not required. Camera bitrates are far below the bandwidth limits of Cat5e.
- Jacket rating
- Use CMR or CMP for in-wall runs, and UV-resistant outdoor or direct-burial jackets for exterior and buried runs. Indoor PVC cracks in sunlight, and in-wall runs may legally require riser or plenum rating.
- Analog/HD coax
- Use RG59 Siamese (coax plus 18/2 power) with a solid copper center conductor and quality BNC connectors. Copper-clad center conductors and loose crimps cause noise and image loss on HD-TVI, AHD and HD-CVI.
- 12V DC voltage drop
- On long 12V runs, use heavier-gauge power wire or power the camera locally. Voltage drop causes night-time IR reboots once the illuminators switch on.
Brands that matter
- Belden: Professional-grade Ethernet and coax with solid copper conductors.
- Monoprice: Wide selection of pure-copper Ethernet and premade cables.
- Cable Matters: Patch and bulk Ethernet in many jacket types.
- Southwire: Bulk low-voltage and network cable for in-wall runs.
What to avoid
- CCA (copper-clad aluminum) Ethernet, even when marketed as Cat6
- Indoor patch cables run outdoors or buried
- Premade BNC/power 'combo' cables pushed past their rated length
Questions
Can I reuse old analog coax for HD cameras?
Often yes for HD-TVI, AHD and HD-CVI if it is RG59 or RG6 with a copper center. It cannot carry IP/PoE cameras without coax-to-Ethernet adapters.
