Hikvision NVR 256-CH No enough network bandwidth

Hikvision NVR 256-CH No enough network bandwidth
I don't think that you will find help about HikCentral Pro servers for 200cam install here on the forum. those solutions are not something you buy over internet using knowledge from some internet forum. You should find some local bigger CCTV integrator, which will show / demo you (and your...- steve1225

Hikvision NVR 256-CH No enough network bandwidth
NVRs are very underpowered devices (comparing to modern intel/AMD servers), based on ARM integrated processors (SOCs) developed for mobile world.. Those 'channel maxed' NVRs are more for situation when someone will need to add a few more cams over half limit of lower model and not fills them up...- steve1225

Hikvision NVR 256-CH No enough network bandwidth
so 0.5 mbit is for second stream.. FPS don't matter for NVR network bandwidth limit... but higher FPS with the same low bitrate decreases video quality (more video frames must fit into the same bandwidth)... ps. man, those bandwidth informations are BASICS... I don't know what type of...- steve1225

Hikvision NVR 256-CH No enough network bandwidth

Hikvision NVR 256-CH No enough network bandwidth
Max bitrate is 5120 kbit (5 mbit) on both.. plus there is sub stream (around 0.5 mbit?), which you didn't showed.. NVR can allocate 5 mbit/s (plus sub stream) for each cam.. and simply don't allow for more that 768 / (5 + 0.5) = around 140 cams...- steve1225

Broadcasting 16CH to TV
you can use hik connect.. but I don't think it will work 24/7 without any problems... apps (mobile/desktop) from hik / Dahua are very bad... most stable 24/7 cam live view is what NVRs have over HDMI.. it simply works...- steve1225

Broadcasting 16CH to TV
1. some android cctv apps on TV with android / google tv operating system (or any google tv dongle)... 2. the same on Apple TV... 3. HDBaseT transceivers which transfers HDMI signal (4K) from NVRs to TV over CAT6 cable (no switches between, direct cable).. 4. HDMI over fiber cable between NVRs...- steve1225
