Black band instead of OST Time

(1/2) > >>

Hi all,
on my DCS935L (fw 1.10, the latest) the OST Time suddendly disappeared.
Now there is just a black band all over the top of the picture (not just the left part, as it used to be).
The height of the band seems to be correct.

I tried, with no luck, to:
- re-sync NTP
- factory reset
- re-write FW
- change video resolution

The problem is present in live video, image setup page, motion detection page, jpg snapshot, video.
Any clue ?



* 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?

What browser are you using when your configuring or viewing the camera? Try IE11 or FF?
What OS platform are you using?

HW version is A1.
FW is 1.10, as I wrote.
I am located in Europe.

The other informations are irrelevant because:
- As I wrote, it stopped to show OST from one day to another (it worked correctly for about six months)
- A "twin" DCS935L (Same HW/FW) in my network is currently working as expected (OST Time correctly shown), so the problem is about one single specific camera.


That is strange. One thing to try is downgrading the firmware and see if it changes. Definitely seems like some weird bug in that one camera. I haven't seen that issue before. If after flashing different firmware, resetting, etc and it doesn't fix it, contact phone support.

the downgrade to 1.09 did the trick.

Right after downgrade the OST was back in place without any other operation (i.e. factory reset).
The subsequent upgrade to 1.10 left the OST in place, fortunately. Again: no factory reset needed.
So: problem solved!  :)

Thank you for the hint GreenBay42!
Have a nice day you all!
