BigCarbs 0 Posted November 30, 2013 I just put up a Dahua mini dome 2mp and I am experiencing the video is lagging and choppy when viewing through my NVR and through my phone app. When I log in with the web server the video is very fluid and motion is smooth. It's only when viewing on NVR or phone when choppy. I am running 3 3mp Hikvision bullets and the one mini dome. also running an analog dvr that I am streaming the video from that to my NVR. The 8 analog channels are running about 800kbs and the IP cams are running about 8,000kbs. The NVR is Dahua ESDV-NVRX-16 supposed to be able to handle up to 160Mbs. Running all cams off a Trendnet TPE-S44 PoE switch. The switch is drawing about 23Wattts with a max of 30. I am wondering if I need a better switch but then if I disconnect one Hik cam I still have the problem Share this post Link to post Share on other sites
BigCarbs 0 Posted November 30, 2013 Well actually I think I do have a slow network. The hikes are lagging a little bit as well Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 Here is a basic layout. All IP cams are set to CBR at 6144kbs Hiks are running 3mp at 15 FPS and minidome at 2MP 30fps Share this post Link to post Share on other sites

milkisbad 0 Posted December 1, 2013 Does your video seem choppy at the NVR when its 1 camera at a time or seeing all the cameras together? If its only choppy when you are seeing all the cameras, check the FPS on your sub-stream. Increase that to 20+ to see fluid motion. Share this post Link to post Share on other sites
luckyfella 0 Posted December 1, 2013 Try lowering the bit rate of each camera. Are you lagging during remote view outside your network? What is your download/upload speed? Go to speedtest.net to find out. But, I would lower your bit rather to 2000-4000 each camera. Also, tell us about your PC, that could be an issue as well.

BigCarbs 0 Posted December 1, 2013 It's either way. When viewing at NVR all channels or one channel. All the IP cams have become a little choppy. Substream isn't nearly as bad. Mainstream when viewing on NVR or the web app is lagging quite a bit. I just can't figure out why it looks great in the cameras web app but NVR app is lagging. I was starting to think that perhaps the PoE switch isn't keeping up but with my math I only have about 30-35Mbs going through it. I might pick up an extra one to split them up and see how that works. Note:I used to have my DVR plugged into the router and the video from DVR that appears on NVR had a bit of a delay and was a little slow. It improved quite a bit when I moved the DVR onto the switch. Note: When viewing the camera on NVR web app there is a good 3 second delay before displaying the change in a scene, such as me walking into room. When viewing on cameras web app the change is instant. This is what has led me to thinking the switch might just be jammed up with traffic. But I am not in the IT business at all so might be way off in my thoughts Share this post Link to post Share on other sites
shockwave199 0 Posted December 1, 2013 I'm actually confused a bit. Where do you see it choppy? On the monitor attached to the nvr? In PSS software? In the web service for the nvr? The phone app? And which phone app are you using? Share this post Link to post Share on other sites
shockwave199 0 Posted December 1, 2013 Have you restarted the nvr? Sometimes it can clear out quirks. Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 I'm actually confused a bit. Where do you see it choppy? On the monitor attached to the nvr? In PSS software? In the web service for the nvr? The phone app? And which phone app are you using? It comes up choppy when viewing on the monitor attached to NVR, the web service for NVR, and on the phone app iDMSS. I hardly use PSS so didn't ever check on that. I setup the iDMSS connected to NVR for viewing and added another device which is the camera itself. all are really choppy, the recorded video is choppy as well, I will try and upload a clip here shortly. Also when viewing the other IP cams they have become a bit slow and choppy as well but the playback seems to be a bit better. Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 Have you restarted the nvr? Sometimes it can clear out quirks. Restarted the NVR, Switch, router, modem, dvr. everything related to cctv has been reset Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 Here is a brief clip. I trimmed this clip down from original. Original started with light turning on , camera switching to color, me walking around room. In original the choppiness I am referring to starts at 45 seconds. in this clip only about 5 seconds in. Sometimes this occurs immediately and sometimes the first few moments are fine then it starts getting choppy Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 This might explain on the phone or outside my network but not viewing on the NVR itself or within my network Share this post Link to post Share on other sites
ssmith10pn 0 Posted December 1, 2013 I would lean towards the switch being the issue. Cut your frame rate back and see what happens. Share this post Link to post Share on other sites
tomcctv 190 Posted December 1, 2013 Hi the problem with that model NVR is that its limited. 160Mbs they list as best with cameras set to minimum. also 160Mbs you have to include calling your DVR to your NVR. try lowering your 3mp to 2mp and see how it goes also just for test remove DVR from NVR. you would be much better sending NVR back and using there hybrid dahua. that takes away switches and a basic local network is all that's needed also the new hybrids are much better on remote view via idmms Share this post Link to post Share on other sites
luckyfella 0 Posted December 1, 2013 Just do a test, lower all of your bit rates for every camera to the lowest possible on the main stream. Do some recording and see how it goes. Than, raise them all to the next level up till you get a happy medium. Your sub stream will be better as you mentioned cause your bit rate is lower. Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 Hi the problem with that model NVR is that its limited. 160Mbs they list as best with cameras set to minimum. also 160Mbs you have to include calling your DVR to your NVR. try lowering your 3mp to 2mp and see how it goes also just for test remove DVR from NVR. you would be much better sending NVR back and using there hybrid dahua. that takes away switches and a basic local network is all that's needed also the new hybrids are much better on remote view via idmms From what I can see on the NVR I am pretty far away from the max. on the screen where it shows kbs for each channel it all adds up to about 30Mbs. Unless it is trying to stream all channels in full resolution out to multiple monitors outside network but I'm not even sure thats how it works. I did a little bit more testing and came up with the following. Keep in mind I am not in IT so I could be way off in my logic. These problems never occured until putting the extra minidome. The low quality on mobile app I would like to lean towards my internet being the problem, or just not being able to get the feed through the switch fast enough? When viewing recorded video on my home network from my laptop, the playback is extremely slow. Almost unwatchable I stopped paying attention to live feed to watch recordings since seeing a slow connection. The only choppy recordings are on the Dahua minidome. All other ip cams and analogs have smooth recordings. The choppy footage usually occurs about 15-30 seconds into the recording. If I unplug 3 other cams from the switch then I can get smooth recording on the minidome. But this doesn't tell me whether it is a switch or NVR. If I get an additional switch of the same model and split the cameras up I would still have the same amount of traffic going through the switch that is plugged into NVR right? Unless I put both switches through the router and have all that traffic go through the router which I don't know if it could handle it. Perhaps the best bet to elimante any switch problem would be a gigabit PoE switch I would assume? Share this post Link to post Share on other sites
VST_Man 1 Posted December 1, 2013 make sure you are setting cam to H.264 and NOT jpeg. JPEG is a monster that eats your bandwidth. Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 make sure you are setting cam to H.264 and NOT jpeg. JPEG is a monster that eats your bandwidth. Not set to JPEG, all cams at H.264 Last night connection was a bit slow. This is about what it usually is when I check Share this post Link to post Share on other sites
shockwave199 0 Posted December 1, 2013 If you take out everything but one camera and it still does it when viewing on the monitor attached to the nvr, there's a problem with the nvr. It'll need servicing or be replaced. Share this post Link to post Share on other sites
BigCarbs 0 Posted December 1, 2013 If you take out everything but one camera and it still does it when viewing on the monitor attached to the nvr, there's a problem with the nvr. It'll need servicing or be replaced. It goes away when I take out 3 other IP cams. I plugged everything back in and it seems a bit smoother now. Maybe I need to give the system a rest for a little bit lol Share this post Link to post Share on other sites
tomcctv 190 Posted December 1, 2013 It goes away when I take out 3 other IP cams. taking off cameras is the same as lowering the res of each. that unit is best at 16 at 2mp fps @ 7 your collecting 12 cameras 3x3mp 1x 2mp and 8 xD1. your spec says 16 @5mp can be run ......... but what the spec does not tell you is you have to lowe the 5mp to D1 to run which is pointless. don't read specs from resellers ..... go to dahua site Share this post Link to post Share on other sites

When I am looking at one with exact specs on reseller website and on Dahua website I see " Incoming bandwidth: 160Mbps" I read that as a total combined bandwidth of 160Mbps and it doesn't really matter what resolution it is. Running a 5mp at 8Mbps isn't the same bandwidth as a 2mp running at 8Mbps. If I was running over 100Mbps I could kind of see what you are saying but I'm showing the D1 analog cams as pulling approx. 700Kbps which is nothing really and the other cams running at approx. 6Mbps. Does a 5Mp cam use 10Mbps set at D1? Maybe I just don't understand fully what you are saying Share this post Link to post Share on other sites
ssmith10pn 0 Posted December 2, 2013 Leave your resolution alone but cut back the frames per second. Your not making motion pictures. Anything over 2MP I run a 5 to 7 fps. Share this post Link to post Share on other sites
BigCarbs 0 Posted December 2, 2013 Leave your resolution alone but cut back the frames per second. Your not making motion pictures.Anything over 2MP I run a 5 to 7 fps. Cut them down to 12 fps on Hiks and 15 on Dahua. Everything else has been good all day except for the Dahua. the bitrate on all has been lowered to 4096. The Dahua has experienced a few freeze ups on the web app and once when viewing at the NVR to the point I had to reboot the camera. I'm considering returning it at this point. Also have yet to be able to get it to record on the sd card but thats another issue Share this post Link to post Share on other sites
