With 4K Ultra HD video you have professional-quality surveillance to see everything that’s happening live or in playback mode, plus you can zoom in close to see car license plates, faces, tattoos, logos on clothing, labels on boxes & so much more. Night2Day™ provides rich video quality & color night vision up to 32ft (10m), that turns night into day. You can also see up to 130ft (40m) in black & white during total darkness. Talk back with people near the cameras. Scare off intruders with the loud siren or ask the delivery person to hide the package somewhere safe. Trigger the siren automatically when activity occurs or turn it on manually via the app.
