Warm tips: This is a 4K AHD camera. If you plan to use it with your existing DVR setup, please ensure that your DVR is preferably a Swann brand one and that its resolution is 4K or even higher. Otherwise, it won't be compatible, and you won't get any video output.
Ultra-Impressive 4K: Video in pro-quality Ultra HD to see everything that’s happening live or in playback mode, plus you can zoom in close to see car license plates, faces & so much more.
Reliable Wired Connection&DIY Installation: Everything that you need is in the pack, including a 60ft (18m) cables, screws & wall plugs, power adapter & splitter and security stickers. Mount the cameras outdoors as their weatherproof design is IP66 rated, meaning they are built to withstand rain, snow & heat, all year round.
See Colour at Night: Get colour video at night up to 32ft (10m) with the lights on & even longer, up to 130ft (40m), in black & white during total darkness.
More Reliable Security: With Swann's True Detect, warm objects like people & cars can trigger the lights, siren, push notifications & recording with fewer false alarms to worry about.
