2025 New Arrivals From EmpireTech
- Thread starter EMPIRETECANDY
- Start date
I would estimate they cost around 200$. The new Tioc Vario Tioc camera cost around 180$.

yea, was more interested in a video reviews.
dont think its been posted, but maybe i missed it.
No, Mike didn’t post anything yet.
Factory beta firmware has many errors, they wait for newer one before post any review
They now also have a siren like the Tioc cameras, don't they? If so, why should you still buy Tioc cameras?
You really can't read the spec sheet?
yes, they have a speaker, which can work as siren...
no, they don't have police red/blue led lights like tioc-pro...
GREAT stuff - thanks for posting Spec Sheets - looking forward to actual reviews.
Comparing the Vari-Focals Specs of the IPC-Color4M-TZ-Pro versus the 5442 (both 4MP), the "Min Illumination" numbers only changed from 0.0007@F/1.8 to 0.0006@F1/1.2 ... so kinda suggests not much improvement in sensor technology(?)
A couple of other things I noticed (but I defer to people like @steve1225 who are 100X smarter) is much closer focusing distance, very similar FOV, same 4GB of ROM, but 2GB versus 1GB RAM (presumably for more processing), IR+Warm lights versus just IR, bunch of AI improvements, no 50/60FPS@1920x1080 (loss?), DUAL microphone versus one(?), Ethernet is still just 10/100 ... no upgrade to 10/100/1000, higher power draw, especially when all the bells & whistles are turned on, little bigger & heavier (maybe due to new lens).
BTW, it would be awesome if they published the maximum F-Stop for various focal lengths - i.e. how quickly does the lens "close up" as you zoom in. Really helpful for low-light situation ... since you may be better off giving up the flexibility of the vari-focal if the largest aperture at the same zoomed-in FOV as the 3.6mm lens on the F/1.0 fixed-focal is much smaller.
Interesting that on the IPC-Color4M-T-Pro, there is only 2.8/3.6mm lens offerings - I've read how focus was challenging with the 6mm lens.

no, basic sensor technology is similar..
main difference is ISP - image signal processor - which reconstruct color image based on RAW data from the sensor.
TIOC-PRO was a first cam where Dahua did huge step here - using modern technology from mobile / sport / drone cams world..
classic 2D & 3D noise reduction algorithms were replaced by AI network (very costly thing).
Also modern full scene HDR, full scene LUT coloring and modern sharpening algorithms were implemented.
I hope next Dahua cams (like WizColor 5459-PRO) will do here even more.
I play with modern sport cams & drones, I know what performance have those cams using 1/1.3" 48Mpx sensors (11x more pixels that we have in 5442) using latest high performance AI based ISP video processing chips...
those specs sheet says nothing about SOC with all internal parts (CPU, GPU, ISP, AI accelerators, used algorithms) and their performance.
HiSilicon (main supplier of CCTV SOCs for both HIK & Dahua) stopped publishing spec sheets and documentations for new chips many years ago (they are on the US black list from many years)...
HiSilicon is also main manufacturer of chips for Chinese mobile phones and sport/drone cams - so they have big progres here (big market with billions invested).
And they simply copy / scale down mobile technology to CCTV chips with some a few years delay using cheaper production processes.
Cams don't require more bandwidth than 100 mbit/s and full gigabit ethernet require almost 1W more of POE power.
New cam can drain more power due more technology (especially AI video processing which is very energy hungry).
New cam can be heavier due more open (F1.2) varifocal optics which will be bigger/heavier, built-in speaker (which must be bigger for siren) and more LEDs..
they never spec this for fixed cams..
sometimes in PTZ cams you can find min aperture for max zoom.
5x42 / WizColor-S cams were last one cams on market with fixed 6mm lenses.. I don't know anyone who produce cams with lenses like this (HIK do only 2.8 and 4.0mm)..
this is a little part of history - original 5x42 didn't have varifocal option for turret chassis - the lenses were to big to fit them.
So Dahua created fixed 6.0mm to give some flexibility when installing turret cams...
After one or two years of 5442 on the market they created new varifocal lens which fitted turrets cams but never canceled fixed 6.0mm variant..

So Steve,
Do you think this new varifocal turret will be better than the current king ( IPC-T54IR-ZE S3 )
Man, there are a few samples of this cam in the world, with not finished firmware, I didn't had any in my hands and You want me to tell you what performance those new cams will have?
Sorry but my crystal ball broke many years ago and the service doesn't want to fix it
Thanks for confirming @steve1225 that it doesn't appear sensor technology changed much ... obligatory WTF when modern sport cam/drones/etc. have improved so much - GRRRR!
Interesting that adding GigE pushed the power draw up another Watt - I assumed that since 10/100/1000 was so ubiquitous that it was a drop-in replacement. And yes, 100 is plenty fast, even if you are manually downloading saved video files.
I may not have been clear that yea, for fixed focal lens, the F/1.0 is (by definition) constant. Just a shame that for varifocal, they don't say something like F/1.2@FOV143 (maximum diagonal for varifocal) , F/1.4@FOV135 (2.8 fixed), F2.8@FOV114 (3.6 fixed), F5.0@FOV2.8@FOV56 (minimum varifocal). It's not like these numbers aren't known!
Love the "history of varifocal in turrets" ... ;-)
Good question @flynreelow which we are all waiting for find out - LOL @steve1225 that I'm sorry to hear that the warranty coverage on your crystal ball has expired!

For the Radar Camera specsheet is this the one which was expected to have the GS-CMOS ? (Global Shutter) or that be a different model ?
Hey guys
Radar camera will coming out soon, it will be 4G and POE optional, but we will get the poe version. Here has a draft specification for your reference.

aha still not release , i just post the specification, this week i think will have prices.
Yes, GS-CMOS, that is right, this camera mainly for traffic monitoring.For the Radar Camera specsheet is this the one which was expected to have the GS-CMOS ? (Global Shutter) or that be a different model ?

So to confirm the LPR431-Z4 is NOT the one with GS-CMOS it be different model ?Yes, GS-CMOS, that is right, this camera mainly for traffic monitoring.

as the spec sheet for The LPR431-Z4 looks like is 1/1.8" 4 MP starlight CMOS sensor.

Very good to see Dahua's Xinghan AI model being used in cameras now. @Empiretechandy
It has been almost 2 years since first announced at Dahua Think#2.0 in 2023.
It has been almost 2 years since first announced at Dahua Think#2.0 in 2023.
it looks like those new Xinghan AI models require more of AI processing power in camera chips.
They will be only available on newer camera models. There will be also a new XI-PRO line of NVRs which will only supports new features like WizSeek, which is based on them...
From bumping camera models from xx4x to xx5x I understands that this is treated by Dahua as completely new take on AI in cameras/NVRs...
Especially that WizSeek presentation shows that cams/NVRs will detect & recognize many different objects (different classes of animals, backpacks, trollers, bicycles, mobiles, all clothing description) - so it is much more than simple human / vehicle filtering we have now on most of the cams...
I saw a few screenshots from new internal Dahua presentations about next generation WizSeek technology and new AI Search...
they will be replacement (or more continuation) of AcuPick 2.0 and Video Meta Data in actual PRO NVR/cams generation...
where we will simply ask Dahua AI NVR using a written prompt (like in AI chats) to find: "a man in yellow clothes who is making a phone call beside a car"
Or: "a women who is pushing a stroller"
there are many questions about this new technology, person who sent me this presentation couldn't answer anything

Get a sample video for the radar LPR camera.

How good does it get the speed of the car? It looks way out of my budget but I take donations hahaha.
