Great test, I have been disappointed with the lack of smart CODECs for DW cameras. When we use DW cameras (we have not used this one) we always have to plan for twice as much storage.

Jul 05, 2018There are 2 types of smart codec, one is that comes from the chipset like HISILICON which also called H.265+, which could work with all the HISILICON chipset with the H.265+ supported, the other one comes from the manufacturer private algrithm which could only work with the hardware/software from the same manufacturer but not the 3rd party of hardware/software.
As for the performance of the H.265, It's related to both the hardware and software, for example, the camera could save 50% of the bandwidth compared with the H.264, but if the software like VMS software which do not implement the H.265 algrithm properly, it possibly could only save 20% of the bandwidth, which could lead to that the camera could only save 20% of the bandwidth when working with this type of VMS software.

Jul 02, 2018Shouldn't someone ask TVT when they will support smart codecs?

Jul 04, 2018#1, thanks for pointing that out! We don't follow TVT that closely so we missed that.
Ethan investigated and his preliminary findings are:
There is definitely something TVT happening but I don’t know enough about TVT and/or DW to say whether it’s simply got a DW logo slapped on it or if they made other changes to hardware and firmware. For example, it shows up in TVT's finder tool.
We asked DW and they declined to comment.
The facts that it shows up in TVT's finder tool and looks just like the TVT unit is pretty strong evidence that they are OEMing this from TVT. How broadly they are OEMing from TVT, we don't know.
Somewhat related, at ISC West 2019, TVT's fairly big booth will be right behind DW's:
OEMing from a company who is happy to have a big booth right next to yours in North America's biggest trade show is not prudent.

Jul 09, 2018Isn't that obvious that DW is not the manufacturer and they OEM from some Chinese manufacturer?

Jul 13, 2018It's definitely obvious it is from TVT. Since we don't have a TVT camera, we can't do as close an inspection.
If anyone has authorized / legit TVT branding products, please let us know as we would like to buy some (john@ipvm.com)

Jul 05, 2018The EXACQ VMS software would not activate the VMD unless that the camera manufacturer name is in the EXACQ manufacturer list, no matter if the camera work properly with the VMD or not with EXACQ software.

Sep 25, 2019Does this camera use any of the banned chips - i.e. Huawei SOC chips?
Derek Ward
Sep 25, 2019Hello Steve,
Yes, this camera uses a banned Huawei chip. However, for this camera, there was a heat-sink rubber mount laid on top of it, and after ~10 minutes of trying to clean off the chip, this was the most I could make out on the chip.
We can easily make out the HiSilicon logo, and a few additional characters.
Ethan Ace
Sep 25, 2019Pretty sure that's an Hi3516BCVsomething. The 3516 is extremely common, and I can read a B on the second line:
There are several other models we've torn down using the 3516B, so this wouldn't be a surprise.
