New night time footage of 20X SDI IR Speed Dome, any idea if the flickering is due to my country electric is on 50Hz cycle while the zoom module is set as 60Hz?

Day time comparison here

 

Note: Somehow this SDI DVR AVI is not accepted by Youtube

Who nice pictures and very sharp

My equipment is poor quality compared to your

can you tell me please the model of your dvr and the camera please

I really appreciate it

Happy ending

The DVR works great

After I contacted the seller

He sent me a RS232 SERIAL Board for the DVR

I connected the PC to the DVR

And updated the FLASH files

And within seconds everything came up again

What I want to say

Never Give Up Never

Then its 95% dead (unless you have wrong flash files), apply for replacement/repair, they will have to change motherboard for you most likely and keep the same case.

i try many files nothing work

hope when i fix it

I'll write you the solution

Well if you got it from direct from China I'm not sure if my instructions would help...assuming you already know which are the flash files and have the correct version, try this:

 

1. Empty and format your USB key

2. put the flash files into the USB without any folders

3. turn off machine

4. plug USB in (try the front and the back, sometimes USB port might be bad)

5. turn on the machine

6. if you get a black screen and if the USB drive is flashing like crazy, it means the firmware is working.

7. wait 15 mins, the machine should reboot and you can login like normal if it worked.

 

I'll PM you with a download link to get the flash files/firmware

Hi

thanks for the help

i already try this steps

but still not work

It is very frustrating

it could be hard drive issue too, turn off DVR, then open the case then unplug the hard drive then try to turn it on.

 

That thing should still be under warranty, that model hasn't been out that long yet, when and where did you buy it?

 

Do you know how to flash that DVR? if disconnecting the HD doesn't work i'll give you further instructions.
