We have iVMS 4200 installed (v 2.3.1.3 ) installed for 8 CCTV cameras in our office premises. The firmware version is V 3.4.1 build 160108.

We have 4 Desktop PCs in all.

However , recently we have had problems with the Software showing error code 302 in 2 of our PCs. As soon as we boot it, it shows error 302, Camera disabled or not connected. It stays that way for 30 mins after booting.

I have a camera system comprising of 5 outdoor Hikvision DS-2CD2T42WD-I5 4MP bullet cameras (purchased from use-ip ltd), and I seem to have problems with 3 of these cameras constantly disconnecting from live view. The strange thing is ,however, that the recordings of all cameras are working just fine, and I can see the IR illuminators of all cameras working nonstop during the night. I don't have an NVR, so I use all cameras independently and I am using a NAS computer to record the footage. I power all cameras with POE.

When I open ivms4200, immediately these 3 cameras are not showing on the live view. However, when I click to reload the camera, it comes back online almost immediately, but then it disconnects again after about 10 seconds. In less then a minute, the camera comes back online in the live view for less than a minute and then disconnects yet again! This cycle then continues forever.

So it seems that the cameras keep disconnecting and reconnecting on the live view, but the footage from all the recordings on the NAS are fine without any missing data. What do you guys think is the issue?

These are the error messages I am getting in ivms4200 "Failed to get stream, start reconnection. Error Code ivms4200.exe[302] Camera is disabled or not connected." Also I get this message "..control PTZ failed. Error CodeHCNetSDK.dll[10]. Receiving data from device timed out.

Anyone knows how to fix this? Thank you very much in advance.

update - I managed to isolate the issue. I ran a series of tests, IP ping tests, and viewed the live view in IE, and came to a conclusion that it is a software issue, so nothing wrong with the camera or network. The live view works fine in IE without any video drops. The ping test showed normal results. The recorded footage is without missing data. So this must be a software issue with the ivms4200. Will probably contact Hikvision technical support.

  Will probably contact Hikvision technical support.

Well, the first thing they will ask you is for the serial number of the device. Then they will tell you that you didn't buy it from an authorised source. Then they will tell you they don't support it.

At least, that's my guess, based on what has been posted on here. Good luck though!

On the use-ip website they state that they are an authorised Hikvision reseller. Anyway, I sent them an email so 'we'll see'. In the meanwhile I was hoping to get some advice from you guys. Oh well...

I apologise for being impatient but this is clearly not getting anywhere. I would like to ask the admin to delete this thread (I can't find an option to do it myself) and please remove my account as well. Thank you.
