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
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

Bug in IPC-Color4M-T firmware?
ok... you have very extreme situation here.. But even here you can play with HLC.. or exposure compensation... and HDR on 3449 will compensate this much better that 5449. -
Bug in IPC-Color4M-T firmware?
Simply don't use WDR / SSA.. On those WizColor cams they are not needed and they are degradation to new WizColor video processing (they disable it). -
Bug in IPC-Color4M-T firmware?
I played with many WIzColor cams at different locations. They when used in 'normal' (not WDR or SSA) mode, are using totally new video processing algorithms, taken from mobile & sport camera world... Algorithm with always enabled full frame HDR, strong local gamma manipulation, LUT color... -
Low-light struggles / improving image quality.
this is a video noise, result of low light, short exposure time, high ISO (analog gain on image sensor) and LOW noise reduction settings... Noise reduction (especially 3D NR) removes this a lot.. but it works only for static image... for moving objects it creates ghosts (results of 3D NR...- steve1225

PTZ5A4M-25X Tracking issues - Dahua SD5A425GA-HNR
if this PTZ model behave bad (we have here confirmation from many users), You should ask Andy to report this to Dahua... Also ask Andy to check for custom firmware version for this PTZ. SD5 is very popular line (something comparable to WizMind-S in fixed cams) - I'm 100% sure, there are many... -
Best indoor and outdoor cameras from Dahua ?
you can use them everywhere, except places where you need strong optical zoom (due big distance - like from gate to building). For good camera with strong telephoto zoom, you need to choose 5442-Z4E (Dahua) / 54IR-Z4E (Andy shop) (2x-6x optical zoom comparing to mobiles). -

Hikvision NVR 256-CH No enough network bandwidth
1. for that large installation You should use VMS not NVR. NVRs are too much underpowered.. 2. it's not how much network bandwith is used by camera. But how much bandwith is reported by camera as maximum which can send. Can you show what encoding settings (all for main/sub stream) you have on...- steve1225
