Dahua WizColor COMING SOON!
turret 5442 also have only 2 IRs... so they should be similar... pictures you sent me by DM shows that IR light is more uniform on 5449... Dahua has saved money here again. Should throw in 4 hybrid LEDs, 2 with near optics and 2 with far optics. Or do like HIK in the latest DeepInMind 2.0... -
Dahua WizColor COMING SOON!
5442-s3 is almost 3 years old product... it used previous generation of video processing, older image sensors & older SOC (processor). it received a lot of new functionality by firmware upgrades, but they can't change that it is older hardware. TIOC-PRO is a new product, which is show case for... -
Got a new NVR for Father's day!!
Enabling AcuPick on NVR downs the bandwith to 200 mbit/s. If you select AI Mode and DON'T enable any AI processing on NVR (only on cameras) - then you will got original 384... At a cost of not working AcuPick 1.0 functionality (search by image - find similar humans / vehicles)...- steve1225

IMOU camera with Dahua NVR
don't think is even possible to revert to that old firmware for 4xxx-ei... Dahua blocked that possibility.. the best solution is to buy from second hand working used 4xxx-4ks2 or 5xxx-4ks2 NVR where owner / installer didn't upgraded firmware for a few years. Dahua sold millions of those models... -

PTZ425DB-AT vs PTZ425DB-AT-R - Low Noise?
I can confirm that SD425DB-AT-R (stealth version of MiniPTZ) is most silent (audible) PTZ which I tested in my life. even more silent in comparison to bigger brothers from SD5 series, which have very low frequency (bass frequencies) sounds.. I have on my desk and I almost don't hear it.. Dahua...- steve1225

Dahua WizColor COMING SOON!
Don't look like Dahua, more like HIK-Vision. Totally new LED diffuser - like in ColorVu 3.0 cams.. Andy please check how the zoom works - what is real range? Previous FullColor 5449-ZE with F1.0 was more like 2x optical zoom only (much shorter zoom comparing to 5442-ZE). Does it have bad /... -

HUGE RUMOR: Unifi Protect will support ONVIF cameras (like from HIK/Dahua)
the problem with Dahua is that they have platforms which are much more modern (have much more modern web UI) and have much more inteligent AI analytics. But they are not offered on cameras (because of limited power) but on dedicated servers with big AI acceleration cards, which can do a lot of...- steve1225

Intelligent visitor data? Available for Dahua yet? Sex, Age, Height, Etc
5xxx NVR can display last 5 AI events (so also Video Meta Data) from all camera as right AI panel on HDMI or web live view (from one or many cams)... DMSS & SmartPSS don't support this feature (they don't understands more advanced AI events - display them the same way as IVS or SMD)... HDMI... -
Intelligent visitor data? Available for Dahua yet? Sex, Age, Height, Etc
this AI is done on cameras (5442-S3).. Full VMD eats full AI power - so no IVS then on camera. 5xxx NVR is required to receive / save / display / search VMD data. 5xxx-EI NVR is requires to support AcuPick data.. 608-XI NVR can do VMD alone on NVR (with any camera) - up to 8 channels. -

Most Dahua & HIK models You gave are not 1/1.2" (mostly 1/1.8") or don't even exist (I can't find them)... Except ColorVu / FullColor cams we know (like Color4K) / use on this from both HIK & Dahua, HIK have a few ultra models with 1/1.2" sensor which have optical zoom and supports IR (or dual...- steve1225
