Trying to upgrade your old analog CCTV system to HD without rewiring? This pair of passive BNC to IP extenders lets you transmit HD IP camera signals over your existing coaxial cable runs – up to 220 meters (about 720 feet)! They're basically little adapters: one unit connects at the camera end, the other at the DVR/NVR end. They're passive, meaning they don't need external power – they draw power from the camera and recorder. Brand is 'smart homes'. They use standard BNC connectors for easy plug-and-play setup. This is a great, cost-effective way to modernize your surveillance without the huge expense and mess of pulling new Cat5/6 cables everywhere. Perfect for homes, small businesses, or anyone with a bunch of old coaxial lines already in the walls. Model is listed as 'ip extender'. Surveillance technology is CCTV. No EAN provided. It's a simple but clever solution for hybrid systems. Just make sure your cameras and recorder support the same HD-over-coax standard (like HD-TVI, AHD, or CVI). These extenders are brand new, unused, in original packaging. A real game-changer for security upgrades.
