FAQs
Why are there different BNC cable colors?
Older Swann systems used different BNC connector colors to identify the cable designed for specific camera technologies or resolutions.
Today, this is much simpler. Swann now provides Purple BNC cables, which are compatible with all current Swann DVR cameras. They are built with higher-quality materials, are fire-resistant, and are UL-certified (CL2 & CL3), making them suitable for both new installations and upgrades.
Can I use the Purple BNC cable with older DVR cameras?
Yes. Purple BNC cables are backward compatible with older Swann BNC cameras, including lower-resolution analog cameras.
If you're replacing an older cable, the Purple BNC cable is the recommended choice because it supports current high-resolution cameras while remaining compatible with earlier BNC camera models.
Can I use any BNC cable I already have at home?
Not recommended.
Although some third-party BNC cables may produce a video signal, Swann has not tested them for compatibility. Cable quality varies, and lower-quality cables may affect video quality or prevent certain camera features from working correctly.
For the best performance and reliable troubleshooting, always use genuine Swann BNC cables supplied with your system or compatible Swann replacement cables.
Do different BNC cable colors affect picture quality?
Yes, they can.
While the connector color itself does not affect video quality, older BNC cables with different colored connectors were manufactured to the standards available at the time and may not provide the same performance as the current Purple BNC cable. Because the Purple BNC cable uses higher-quality materials and is designed for today's high-resolution DVR cameras, it can deliver a more reliable video signal and better image quality.
If you're upgrading your cameras or replacing a cable, Swann recommends using the Purple BNC cable for the best compatibility, performance, and long-term reliability.
Can I extend my BNC camera cable?
Yes.
If you need a longer cable run, use a compatible Swann BNC extension cable that supports your camera's resolution. Using the proper cable helps maintain video quality and camera functionality over longer distances; but you must be aware what power adapter to use — the longer the cable, the less power it will have at the end.

Why It Matters
Using the correct BNC cable helps ensure stable video transmission, supports your camera's full capabilities, and makes troubleshooting easier. Choosing the recommended Purple BNC cable also helps future-proof your installation if you upgrade to newer Swann DVR cameras.
Summary & Next Steps
