It looks like Dahua want to release new WizColor cams with AI-ISP at 16 April...
Dahua WizColor COMING SOON!
- Thread starter steve1225
- Start date
Looks like they hired the same marketing team as reolink
And at 76 I can't stand the quick takes from scene to scene where an image is shown for less than a half second before it's gone and another one takes its place. Such items are clearly NOT geared for me nor aimed at me and I won't be buying them any way. I'm thinking the current generation of kids that can't find their butts with both hands will enjoy using them....
Ditto what others said that the video doesn't really say/answer much besides it's a WHODUNIT ... or I guess WHATISIT?!? ;-)
Regardless, thank you @steve1225 for flagging this since ideally after April 16th, there will be more info and I look forward to reading your usual excellent analysis/commentary.

my suspicions of new WizColor models:
- varifocal for TIOC-PRO (3x49-PRO),
- more models with different resolutions for 2x49-PRO (for now there was only 4Mpx),
- more toy mini PT cam (PTZ without optical zoom),
bigredfish
Known around here
those fixed TIOC-PRO models were released last year...
Andy have Color4M and Color8M models in his shop..
We waiting for ZAS-PV-PRO (not AS-PV-PRO) models - with varifocal lenses
If you're healthy, yes.
Dark yellow if you're taking B complex vitamins.
I'll stop now since this is a camera forum AND I'm ALSO not a pee expert.
Interesting chart @steve1225 - we'll find out soon enough what "Large pixel size, Large aperture" means in a vari-focal.
I.e. the current fixed focals are F/1.0 with 1/1.8" sensors. So will they try to put that fast of lens in the varifocals (hopefully not closing down much in the tele end) and/or will they increase the pixel size and upgrade to a larger sensor?
Thanks also for posting that DJI Air 3S video which was stunning in terms of the image/video quality at low light. For example, I didn't see much motion blur on that truck (I'm assuming they didn't "fake" it by speeding up the video) at sunrise/sunset at 1:27 - the lack of noise and dynamic range is impressive.
It uses a full 1" sensor and sells for about a $1,000. I don't understand why a camera vendor could not "remove" all the "drone stuff" and sell just the camera only for less than $500.

Dahua have one varifocal model with 1/1.8" sensor and FIXED F/1.0 aperture (how? I don't know):
I have it, zoom is limited (much smaller that 5442-ZE), it's brighter that 5442-ZE, but I don't like FullColor image processing and not sharp details at 10 meters distance..
HIK have many DeepInView (highest AI line) varifocals with 1/1.8" sensor and aperture starting at F1.2 (not constant). Fixed ones are F1.0
Totally different markets and companies.
DJI is end-solution for end-user company - they sell direct (and by normal resellers with small margin), offer best on market hardware, SOFTWARE (mobile / desktop / firmware) and SUPPORT.
They offer support and warranty directly to end-user.. You can buy extra warranty from DJI for drone accidents (you hit a tree or something, they will replace broken drone by small fee). It works very well.
You can call/write to DJI support team, there are official DJI forums.. Firmware updates are huge (many new features) in first 2 years..
DJI is Chinese company, but it looks like managed by western people and it creates products for western clientele. The margins on hardware they have very high. But the value of product and DJI ECO-SYSTEM is huge.
HIK / Dahua / Uniview are OEM company - they produce very cheap OEM hardware, which is sold mostly under western brands. Some production is sold under main brands.
They sold very cheap, price is inflated (2-5x times) on western side by western brands which sell products and offers warranty / support.
Hardware is good (higher line).. Software/firmware is on weak side, firmware upgrades / fixes are minimal..
Support from HIK / Dahua is non existent, You can't call them..
This is normal for Chinese OEM companies - they offer cheap non-branded HW, but You must order them in shipping containers sizes and You have 2-5x times margins for selling/supporting them..
DJI have access to very good high resolution (mostly 48 Mpx) Western image sensors from Sony, created for mobile (smartphones, drones, sport cameras) and profesional photo/video cameras markets (DSLR, mirrorless photo/video pro cameras).. Plus High-end SOC with modern mobile/professional video processing and AI processing.
Those drones they literally follow the man/bicycle/car and follow him, regardless of obstacles /trees etc/ based on vision from sometimes even 6-8 cams and sensors (ultra sonic, LIDAR in latest models) around drone (360 degree sensing)..
HIK/Dahua are using cheap Chinese CCTV sensors (which see IR) at 2/4/8 Mpx.. There is minimal development for this segment of sensor market (too cheap).
Both Hik and Dahua don't even use newest Sony Starvis 2 sensors (You can find them on premium dash cams from other Chinese companies), which are on market for 2 years now..
ps. following the owner on bike by DJI drone and AI processing:

Great info as always @steve1225 and roger that they are different markets/business approaches.
What puzzles me is why HIK/Dahua don't at least offer a "premium" line that has the better sensors, SOC, etc.
As you point out, Chinese dashcam vendors are using the Sony Starvis 2 sensors. What is preventing the HIK/Dahua's from upping their technology game?
LOL that a camera doesn't need LIDAR ... so echo's my earlier comment that a camera with image quality comparable to that DJI should be doable for less than $500.

In 2019 both HIK and Dahua were cut off from western chips (SOCs from Ambarella) by US government.
Ambarella SOCs which were used in that time in higher camera lines (due AI capabilities).
They were forced In short time to migrate all higher camera lines to Chinese SOCs..
This is way they probably don't have access to modern Sony sensors too (some US regulations)..
Or don't want to risk the same situation, when they will be forced to migrate to different provider in short of time.
I appreciate the education @steve1225 and roger all that ... but it seems puzzling that since there are Chinese dashcam manufacturers (and DJI!) getting "high-tech sensors", why haven't any of those vendors expanded into the camera business as it seems like a would not be technically difficult. But yea, various other "issues" to worry about as you imply above - shame that politics "gums" things up, but it is what it is.
I don't mean to drag out this thread. At the end of the day, we can only buy what the vendors are selling.
