OK, so that does confirm that there is an audio stream defined in the clip, using MPEG encoding.
I should have also said to look at the statistics, which would show what's being done with it.
Do you by any chance have a short harmless clip you could share, to check out?
The NVRs from various manufacturers in my experience use a proprietary HDD layout that's optimised for the specific use case of an NVR recording multiple continuous video streams.
They don't use any of the common general-purpose layout schemes.
If you do a Google search, you should be able to...

Greetings to all participants of the forum!
Need help. There are several old HiWatch DS-I200 R2 IP cameras on the platform, factory firmware V5.4.4_170313.
It is necessary to install V5.4.3 build 160705 with the backdoor capability .............=YWRtaW46MTEK, for additional...
That XML file from SADP is a password reset request file and does not hold any passwords, just a signed request code.
When processed by a Hikvision system with their private key, creating a response file, the originating camera authenticates that file with the public key and clears the locally...
If the NVR was providing a standard IEEE 802.3af/at facility, it would not be possible to measure the full supplied voltage until the powered device (eg camera) had completed the prescribed handshake that's needed before power is turned on.
Prior to that, a small voltage could be measured as the...
That's for the (C) hardware variant.
Over the past several years there have been significant semiconductor supply chain problems, resulting in hardware variants of many models, which have required corresponding variants of the associated firmware.
It's a hard-to-spot subtlety that can be quite...
My guess would be that the novodio NVR isn't using standard PoE for the connected cameras, maybe something like a 12v output.
Is there any more info on the camera label than what's in your screenshot?
Via the router? Hopefully that's the cause.
Even low-cost switches should achieve full-speed non-blocking performance on all ports across their backplane.
Less likely to be able to do that are the ethernet switch ports on some routers. Their primary task is the routing function.
No - the cable connection between the house and office.
You said the video was choppy, so potential congestion on the trunk between them.
Assuming it's local access you're referring to, not access when you're away from the location.
OK, scratch that idea then. Pity.
Assuming you changed the password on both the NVR and on the camera.
Which it seems you did.
Apologies for the dumb question.
What's the speed of this connection?
Based on your diagram - only internet traffic is going via the router.
Unless what you're referring to is when you are remotely accessing your network.
The cameras and the BI PC are all connected locally via the switches.
I don't remember the allowed password specs for the firmware on the E-series NVRs - but if for example the camera password was longer than say 16 characters and the NVR was limited to using 16 characters to connect to the camera, the camera would then complain about 'bad password' when the NVR...
Dumb question for which apologies - is it possible that the camera password is too long or uses special characters that are invalid for that older NVR?
What does SADP show for the models and firmware versions of the cameras?
Many of the older firmware versions have security weaknesses that allow passwords to be extracted.
Quite right, and Hikvision is a great example, the largest CCTV manufacturer globally.
@jrczz
You experienced one of their security failures yourself!

I'm wondering if the download location has been sandboxed by the Windows browser folder virtualisation mechanism.
Is Edge running in IE mode?
Previously, with native IE11 it was necessary to add the target IP address to 'Trusted Sites' to avoid the data being sandboxed and hard to find.
