I am reaching out to the MB community in the hopes that there is an expert out there who can assist me. I have tried contacting Dahua directly but had no response yet. The kit was recently purchased from TopCCTV, who are trying to resolve the issues but have not managed to do so yet.
I am experiencing a few problems with my Dahua CCTV System. Let me explain.
This is what I have;
NVR DHI-NVR4116HS-8P-4KS2
System Version: 3.215.0000000.4, Build Date: 2018-01-19
Litebeam LBE-5AC-Gen2 (x1)
Firmware version: WA.v8.4.2
Litebeam LiteAP AC LAP-120 (x1)
Firmware version: WA.V8.5.11
LiteBeam M5 (x2)
Firmware version: XW.v6.1.8
4MP (x4)
Device Type: IPC-HDW4431EM-AS
System Version: 2.460.0000.15.R, Build Date: 2017-09-07
5MP (x2)
System Version: 2.622.0000000.18.R, Build Date: 2017-11-10
These are the issues I am experiencing, any advice will be greatly appreciated.
1. The live video feed, in particularly from CAM5 on the NVR is still laggy with as much as 7 seconds sometimes between one frame and the next
2. The Motion Detect Email Events are very unreliable. Sometimes there is no Event with a Snapshot sent (yet there is one without the Snapshot) or sometimes there is a corrupt Snapshot attached or a Snapshot from the wrong camera or sometimes only 1 or 2 Snapshots are attached where all 6 cameras have been selected. It is extremely unreliable.
Below image is corrupt.
3. A question I have asked Dahua is why are there 3 emails for every Motion Detect alert (GMail and MWEB have already blocked sending via their SMTP servers due to excessive email)? Why send one email for a Motion Detect Event and then another with the attached Snapshot? And surely a "Clear" event is pointless on a Motion Detect?
Something of interest is when reviewing the live video on the NVR as compared to the same live video on my PC in Internet Explorer there is a clear difference, the live video on the NVR is laggy and breaks up but not so in Internet Explorer (on a slow PC)?
Compare this,
The compression is set to H.264H. I have changed it to H.265 with no difference.
Currently I have the Bit Rate set to 4096Kb/s and Frame Rate set to 20FPS. I have tried setting the Resolution to the lowest on all the cameras, ie. 720P, it made a little difference but still not smooth video, not near 20FPS. I also have not enabled the Sub Stream.
According to the Litebeam on my premises incoming bandwidth used is about 50Mbps.
This is what the layout is, note the 4 Litebeams (.21, .22, .23 and .24) and the 6 cameras. Take note how the AP at .23 is being used to 'relay' the signal from .22 and .24 to .21 at my unit.
Any advice is hugely appreciated, I am at my wits end, we have spend days trying to resolve these issues.
Thank you
Kevin
