Review-Dahua IPC-HDBW4231F-E2-M Dual Starlight Cam

Getting the hang of it
Ok, I have to ask this again. Has anyone noticed a good jump in their CPU usage with this dual camera? Previously, I had seven cameras (a few 6mp) that averaged around 28-35%. After installing this camera, it jumped up to about 55-66%. I wouldn't have expected that much of a jump. The settings for this camera are the same as the other seven. When I disable this camera, it immediately drops down to its original CPU usage.
What happens if you enable this camera and disable 2 others?
 
I just gave that a try. I disabled three other cameras while leaving this dual camera enabled to get the CPU usage back down to where the original seven had been. It just seems like this dual camera is requiring an extra amount of processing power, at least for me. Maybe that's why it gets so hot.

I actually ended up getting one of these yesterday. Once it arrives and I find time to go in the attic, I’ll post back with the results on my system.

Hey guys,
I Went to the page and I was able to setup IVS for IPC2; unfortunately, IPC2 does not record when the wires are tripped. Same settings on IPC1 produce numerous recordings as expected. Any ideas? Thanks!

What are your other cameras? What are their bitrates, encoding, etc.? Unless everything is the same, you can't make a comparison.
 
Has anyone tried the PFB203 to mount this horizontally against a wall. I don't want to mount the camera flat against the wall.

Yep - down the side of the house in corridor configuration. Also used the equivalent for the single camera version at the back door.

FYI, camera came in today and I was able to connect it to BI. My previous idle cpu usage was about 19-21% and now with both channels active and recording it’s around 22-24%. Hope that helps.

Doesn't help my situation. With seven active and recording cameras, it fluctuates from 35-45%. Enabling this dual camera it bumps up around 55-65%.

i belive this is a known firmware issue with this cam. IVS can be enabled for only one of the cams (not both at same time), for some reason...

The Data Sheet from Dahua lists the PFA137 junction box you can mount to a soffit/wall. And the PFB203w for wall mounting.
I was hoping there was something at 45 degree angle because if I mounted using the junction box, I wouldn't get as much coverage from the wall I am mounting on. I saw some corner brackets for this, but this would be the opposite of that corner mount.

If nothing else, you can use the PFB203 and drill and tap your own holes in it with the camera rotated to the desired angle.
