Smart Codec.

That is not true. VBR fixes the quantization / compression level and also the bandwidth level to vary to maintain that compression level. CBR fixes the bandwidth level and varies the compression to fit within the bandwidth set. Whether it is VBR or CBR, any interframe compression (like MPEG-4, H.264, H.264) will 'only records the part of the pic that changes from frame to frame' so that part does not vary between VBR and CBR.

CBR is risky since is the bitrate is too low for what the scene needs, compression will be lowered. Imagine a school, empty on a Sunday vs when students are changing classes on the middle of Monday. On Sunday, with CBR, compression level will be quite low, since not much bandwidth is needed for an empty hallway. However, on mid-day Monday, compression level will spike and quality will be degraded as the camera is forced to stay within the set CBR level. The only way to prevent this is to set the CBR level quite high and then you are, by contrasting, wasting bandwidth on Sunday in this example. Net/net use VBR.

Thanks for the correction @john-ipvm , I'll learn someday to stop posting when it's late and I'm tired. :facepalm:

Changing to VBR now.

If using the Web Service reading, storage currently has used 1740 Gigs over about 289 hours = 144.5 Gigs per 24 hours.

If using the Smart PSS reading, 1788 Gigs over 289 hours = 148.48 Gigs per 24 hours.

I'll see what the rate per day is, the next time I check.

Does anyone else have an opinion, on whether I should use the NVR's web service (accessed by entering the IP address of the NVR) for storage readings, or Smart PSS? Since they measure different total capacities and storage used.

I want to use one and stick with it.

Smart PSS shows 4 more decimal places of precision for storage readings, than the Web Service.

But since they also don't have the same capacity (7.27 for the web service, 7451.80 for Smart PSS), I'm not sure which one to believe.

If I select VBR, there's a new drop down that asks for the image quality on a scale of 1 - 6. I selected 6.
 
This is much better. I've used 90 Gigs in the past day according to the Web Service reading, and 86 according to the Smart PSS reading.

I'm not going to change the bitrate. Now I'm getting the storage usage rate I had expected, before purchasing the system and installing it. Even a little better.

@crossStreet , @jmcu, since you also use Smart PSS (from other threads), do you have an opinion on which storage capacity and storage used reading I should use?

I don't use smart PSS. I tried, but I find web interface to be better.

As for storage. I don't understand you question well. But here is what I have. I have 5 cameras, one of them (PTZ) is set to record permanently, the other 4 only on events. I don't use smart codec (IVS will not work with smart codecs). With this setup my 3TB wd purple should last for over a month, which is fine. I also ftp the event videos and images to a cloud. A day of event footage from 5 cameras take around 10 GB of storage. This will depend on amount of people passing by your place. I have 20-30 people, and around the same number of other animals (magpies, hedgehogs, pheasants, dogs, cats) per day.

Thanks for the response. I kind of like the web interface better too. It just seems like things work better the first time with it. Whereas with Smart PSS, sometimes I have to try multiple times to get something to work.

Let me try re-phrasing my question, though.

The questions are:

Why do I see one storage capacity with the web interface (7.27 Gigs), and one with Smart PSS (7451.80 Gigs)?

Which one should I use? Which one is more accurate?

They also measure different amounts of storage used too. 1830 Gigs from the Web Interface, 1874 from Smart PSS.
 
I don't know, sorry. I would not exclude they mixed up TB and GB and used different conventions, such as 1024 vs 1000.

That's a pretty good explanation. If I take the web interface reading for capacity and multiply it by 1.024, I get close to the Smart PSS reading.

If I take the storage used and multiply it by 1.024, I get exactly the Smart PSS reading.

Thanks. That explains the difference.

@nuraman00 Don't get to hung up on what Smart PSS reports, it's not too smart. It has many quirks and is overdue for a much needed update.

Thanks.
