DCS-960L Triggered FTP JPEG Image Snapshot No Longer Works After Power Cycle
pab49162:
Hi,
I just bought a DCS-960L webcam and I am seeing a weird problem with the FTP snapshot function. I have used a similar function on other DLink webcams (DCS-930s and DCS-933Ls) and never had any issues.
I have the DCS-960L webcam configured to take a JPEG image snapshot every 30 seconds and upload that image to an ftp account on a server. After I set things up and save the settings, the webcam work just fine. A new image gets uploaded every 30 seconds and is stored in a dated folder, such as 20171218, on the server. I can also press the Test button on the FTP page and the test image uploads as expected.
The problem I am seeing is that the snapshot function no longer works after a webcam reboot or power cycle. However, the Test button on the FTP page still works and uploads the test image. So I am assuming the ftp info in the saved settings is correct. In addition, the Event Log shows a "Snapshot trigger by Schedule" event every 30 seconds as expected.
When I look at the System Log after a reboot or power cycle, I can the following which shows the uploads failing:

After messing around with this for a while, I believe the problem has something to do with the resolution of the FTP Host Name. If I specify an ftp hostname like ftp.mydomain.com, the snapshot function no longer works after a reboot of the webcam. (But as I mentioned earlier, the Test button on the FTP page still works.) However, if I use the ip address of the ftp server, both the snapshot function & Test Button still work after a reboot.
I tried 3 different versions of firmware and the behavior is identical in all of them.
Any ideas or suggestions would be appreciated.
Thanks, Paul

* What Hardware version is your DCS? Look at the sticker behind or under the camera.
* Link>What Firmware version is currently loaded? Found on the DCSs web page under status.
* What region are you located?
What Mfr and model is the main host router?
As a work around solution, can you keep the IP address of the FTP server instead of using the domain string?

Hi FurryNutz,
Thanks for the quick reply.
The hardware version of the webcam is A1. I have tried 3 different firmware loads - 1.03.B05, 1.04.02 and 1.06.01 Beta. All 3 versions exhibit the same issue. My region is USA.
My main router is a NetGear WNDR3800 with Firmware Version V1.0.0.52. (I have several other routers and may try connecting to a different one tomorrow to see if that makes any difference.)
As far as a workaround, I could continuing using the IP of the FTP Server. However, I would prefer to use the server name in the event the webhost moves this hosting account to a different server. This webcam is going to remotely located and changing the FTP IP remotely could be a challenge.
Thanks, Paul

One quick update - I connected the another route directly to my cable modem today and then wirelessly connected the webcam to that route. I then repeated the previous sequence using both an ftp hostname and ip address as the FTP Host Name.
Unfortunately, I got the identical results as I did with my primary router. After a webcam reboot or power cycle, the snapshot function no longer works if I use an ftp hostname. However, it does work correctly if I specify an ip address for the ftp server. As before, the Test button on the FTP page works and correctly uploads the test image in both cases -- an ftp hostname or ip address specified for the ftp server.
I have also contained DLink technical support about this issue. It has been escalated to the senior analysts and one is suppose to call me back when available.

Keep us posted on how it goes. ;)
