I'm in Canada too. "HIK OEM" doesn't help me. What's the model number? Hik's website doesn't even list their Acusense turrets (let alone any 8MP models) and the only 8MP one at ADI is the DS-2CD2386G2-I with no light/speaker. Only the 4MP DS-2CD2346G2-ISU/SL has those features.
There are two contradictory phrases I found in the article. I just wanted to clarify if the animal false alerts are better with the newer beta firmware.
- "G2 did not false alert on animals when using higher confidence settings, though some issues were still possible using default settings."
- "When using default settings ("Basic"), the analytics frequently alerted on small and large animals. These alerts could not be eliminated by using increased Target Validity settings, with 1-2 alerts per day still occurring at Highest."
The beta firmware lowered the amount of false alarms on animals but still did not get rid of them completely, there were still 1-2 a day using the "Highest" target validity setting. Thanks for pointing that out, I corrected it in the report.
Hikvision has not been claiming to develop SoCs and, in particular, nothing like this for deep learning. The most likely answer is that this is from Huawei, but is unbranded, since Huawei is the largest provider in this space and we have heard previous reports of Huawei shipping unbranded chips in the past to large customers like Hikvision.
When you say most likely Huawei, do you mean Huawei HiSilicon SoC?
While a lot of the smaller (including UNV) Chinese IPC providers are claiming to have changed SoC, Dahua and HIK don't seem to be going the same promoting this. So I suppose I am wondering do they have some secret in-house solution or maybe they have so much stock that they don't need to make rushed changes.
Whatever is happening in the supply change there is a lot of issues, while Dahua seems to have plenty of certain chips (most likely non-HiSilicon) they are rejecting lots of orders on certain SKUs relating to HiSilicon.
I have the 8 MP turret, model DS-2CD2386G2-I, and indeed it is miles better than the higher dollar "Smart" series from Hik in terms of AI performance. What you don't mention in this review, however, is that Hik's bounding boxes on identified people or vehicles are still very large at times.
Large enough to trip a line crossing line drawn on a driveway when the car is in the street, for example. If I recall correctly, your reviews on Bosch show bounding boxes much tighter to the object being detected, such that this would not happen. I would suggest that you need to include this sort of information in your testing. Hik's bounding boxes are also always rectangles, where again I recall seeing others with much more than 4 corners such that they can better follow outlines of objects. Unless I'm mistaken this fact alone means Bosch is better AI wise, and probably ditto for Avigilon.
The newer firmware is available at the link below, but I have not tried it yet to see if it makes a difference in bounding box size.
