Received my new NVR today. Hooked everything up, still setting up a few things such as e-mail, etc...
but I'm running into troubles with storage and snapshot.

From the NVR settings itself, under "Storage" then "Record Mode" and "SnapShot".... I'm only able to have 14 out of 15 cameras set to "ON". If I try to put the 15th camera to "ON" I get the following error: scheduledReached max bit rate. Need to close channels:15!

I'm setting this up exactly like I had my 4ks2e NVR. Bandwith Remaining is 205 out of 420Mbps.

I really don't have a clue what to look/set to fix this? Tried searching the web and didn't come up with anything for this specifically.

Anyone have a clue? Thank you,

One other problem: When looking at the monitor, in this case with 16 cams up on screen (though only 15 are filled), and the snapshot to the right hand side along with the details, if I click on the SnapShot picture, it just brings up a black screen instead of the actual Snapshot picture. I must have a setting wrong somewhere, but I don't remember where it is?

Again, thank you.

Bit rate is the cameras outputted data rate, so H.265 is far lower bitrate than H.264 camera.
When a snapshot is taken by the camera, it is a full resolution and not compressed as-much (as H.265). I'm guessing your NVR is calculating bandwidth based on every single camera taking a picture at once and this exceeds 420Mbps.

But why are you setting up snapshot...? Setting to record is more valuable than a still photo.

Is this the 'AI live preview' display?

If that is true, then the 4ks2e can handle the snapshots, with only 380Mbps total, better than the newer EI series. If that's the case, very disappointing.

As for why I'm taking snapshots? I like to be able to see what has happening/happened by looking at the right hand side of the screen, as well when going back to view in the AI search.
I do have record set as well.

The AI live preview shows a preview image without actually needing to record the snapshots from the camera. The preview image is a frame of the video, not an actual snapshot loaded from the camera.
A snapshot is when the camera takes a photo and sends it to the NVR. It's at the highest possible quality the camera can achieve.


When you open an event from the AI preview, the NVR is now searching on the HDD for that video.
A blank screen would likely indicate encoding problems or,
your HDD does not have enough cache space to load the data quick enough or,
the NVR has not recorded that video.



I got a NVR516-I NVR, and only have recording schedule set for mainstream video to 'general' (constant recording). Snapshot is not enabled.
The AI preview image is an image of the video. It's stored in RAM from when the event happened.
Opening the event loads from the event from HDD, which relies on the video being recorded in the Recording schedule.

Interesting. What about sending e-mail when an event occurs? I have things set up to send me e-mail if my porch camera captures an event... does that not use the Snapshot?

I believe it does use the camera snapshot for this.


Which brings back the original question of bandwidth Mbps... damn.
I cannot remember the exact menu it's under (I'm at work currently), in settings there is an option to view the current Mbps input from each camera.
Lowering snapshot quality may help reduce the bandwidth too.
Changing snapshot recording settings to 'motion'/'IVS' also means snapshot is not running constantly. Snapshot set to 'general' (green) is taking a snapshot as per the interval set. Which may mean it's taking a snapshot every 10 seconds for every camera.
The maths about checks out... 4 camera taking a 25mb snapshot, that's just under 400mb/s. A scheduled snapshot takes all snapshots at once.

Ahhh.. yeah. That makes sense about the snapshot general, ivs etc... Lemme try that out and see what happens.

Nope. That doesn't change a thing. Still can only do 15 cameras, and still can't get a full screen when clicking on the picture to the right.

Figured it out. Even though my monitor supports 3840x2160, and even though the NVR states it supports this display resolution, it doesn't, for me at least.
By putting my display resolution to 1920x1080, it all works fine.

Thank you JD and Mark for your help.
Thank you @EMPIRETECANDY for your help as well. Hopefully Dahua can update this to truly support 3840x2160 resolution.

But your original error was : scheduledReached max bit rate.

You basically lower the total Bandwith because using resolution 1920x1080 instead of 3840x2160 to make it work.

You're correct. Something in the firmware is not allowing 3840x2160 to work correctly. I don't think it's supported, even though it comes up with the ability to set it to that display.

Spoke too soon. Now it's stating I only have 236M/bps total available instead of 420M/bps, which is now shutting off 2 Snapshot.
I tried default with restart. Tried factory reset.

Something is very very wrong.

I went back to look at the NVR stats again, the decoding capability can only do 8 channel 8MP@30 fps.

And 16-channel can only do 4MP@ 30 fps.

With all my fooling around, had to configure a few of my cameras again. :)
Viewing everything in 1920 is a step back, but would like to continue with 16 cams up on the screen. I like the ability to glance at the screen to see if anything is going on.

Not exactly sure how I'll end up setting that part up.

Still setting up a few things, but getting closer.

Now I'm getting, with a 16 cam screen display, 1 cam display going totally nuts. Over saturated colors filling the entire screen for just 1 cam.
I've tried a 8 cam display, 9 cam display, etc.. same thing. 1 cam screen going nuts. Not the same one depending on what number display I have up.

I have changed HDMI cables, tried different monitor, etc.. same thing.
Logging into the NVR with a laptop, the 16 cam display works fine.

I'm thinking perhaps the HDMI connector on this might be screwed up, or ???
 
If anyone is wondering what this scrambled picture looks like.
I have another HDMI cable on the way just to ensure the 3 I've tried have all gone bad at the same time. Doubtful, but I've seen stranger things happen.

This scrambled picture happens regardless of the number of cams displayed on the monitor. I tried changing the NVR from PAL to NTSC, which only made matters worse.

To me, it seems as though the HDMI port is being overloaded with data or more likely the HDMI connection is bad.
I'll try the new HDMI cable when it arrives, but.....
