Sixteen cameras. One building. You need a recorder that keeps up without you sitting in front of it all day. The NVR2016H handles sixteen simultaneous feeds with 4K HDMI output and an 8-ch@2MP decoding capacity, so live view and playback stay smooth even when everything's running at once. H.265+ squeezes the video file down without smearing the image, which means your drives last longer between swaps. ONVIF keeps the door open for any brand of IP camera you've already got on site. New VIGI unit? Plug it in and it's live. Up to 20 TB of storage (around 1,048 days of continuous recording) sits behind your footage. Two-way audio lets you scare off whoever's wandering the car park at 11pm from your phone
