What firmware was this tested with? There are plenty of camera models that have firmware upgrades that add the smart codecs.
If it is a branded model please update to: DH_SD-Mao-Nova_Eng_N_Stream3_V2.460.0000.7.R.20170317

And if your firmware predates January, you might want to update the mechanical firmware as well: General_SD6A9XXXS-HN_V3.02.20.R.170116.zip

Thanks, I believe 2.460 is the version we used. We updated it to latest prior to testing. I will double check things and report back.

That's just the general version. Build date matters a lot.

Build date matters a lot.

Sure, to the stability but not capability of a release.

Did Dahua really decide to add Smart CODECs to a build without a change in major or minor version number?

Well the minor version number is the .0000.7 at the end, but I'm not sure which one you guys had.

Those are the last two release notes I can find atm. They've released some new things all of a sudden and I'm just getting my bearings after the hurricane down here.

The Axis q-6155e needs the Laser IR from the Dahua and the Dahua needs the Laser Focus from the Axis.
