video stops after 15 seconds in dahua dvr.

[manky 0]

Hello everyone,

i bought a dahua dvr for one of my work sites. when i checked it at my office, it was fine.

i could view the video, login the dvr, change the settings and all.

 

but when i connected it at the new work site, and tried to access it from our old office, problem started.

the problem is this.

i am able to login and change settings. but, when we select video to the window for viewing, it plays for a short time only. i.e for about 20 - 25 seconds. after that, video freezes.

 

we thought its a network problem and brought down the fps, bitrate and video quality and restarted the dvr and pc.

still, the same problem.

 

the network is a wan.

the dvr is dahua DVR1604HF-S - 16 channel.

the pc we connected is a win7, core 2 duo, 4 gb.

tcp - 37777

udp - 37778

http port - 80

rtsp port(i dont know what that is)- 554

max connection-20.

(these are all settings on the dvr)

the software is pssV4.05

 

i would also like to know what the transfer mode implies. theres 3 options. latency, fluency and self adaptive.

it would be a great help if anybody knows how to deal with this issue. thank you.

Set the DVR network to:

Transfer: Fluency

Lan Download

 

Check your encoding.

HF-S is Full D1 30fps each channel.

 

Connect in Extra Stream but change the Extra Stream settings to:

CIF, 7, VBR, High/Highest (4/6), 160/256

 

Then try again.

 

Also make sure you have the updated 4.05.3 which fixes some bugs in the initial 4.05 release.

thanks rory. i tried all that you said and still stuck.

dont know whats the problem.

 

i tried with ur dahsoft viewer. that also didnt me anything better.

the windows loaded much faster than the older situation. that was the only change.

the windows loads an image and then again goes stuck..

 

there is also no loss in the network..

Could be a network issue, router issue or something to that effect shutting down your video streams because of exceeding bandwidth. Have you tried viewing this from another remote site to check, if it happens on another remote site, then its something at your network where your DVR is located. Also, have you tried opening one camera at a time.

Does it still do it with my single viewer?

That will only stream one camera at a time, so if it still doesnt work like that then there is something else wrong. I can get that to stream from the slowest sites down here.

Did you solve this problem? I have the same exact issue. It times up and freezes after 20 seconds on IP cameras, but I can log into the DVR and view the video on the internet fine. I thought it had something to do with the refresh of the monitor etc.

 

but now I'm certain it's network related..... It worked on my home network.. but not at the install site...
