I apologize but I thought it would be better if the members who are already in this forum knew some information=)

My camera is dead and I want to revive it. My question is, what are the connection pins for the UART port? Is additional hardware necessary to connect to the UART of this camera other than USB-TTL? Has anyone been able to establish communication through the UART port for this camera?

Has anyone been able to establish communication through the UART port for this camera?

Thank you very much in advance for all this information, but since you are in a conversation about the hardware of this camera. My camera is dead and I want to revive it. My question is, what are the connection pins for the UART port? Is additional hardware necessary to connect to the UART of...

I have the same symptoms with this same camera model... could you solve the problem? Could you re-enable the camera?

I have an SD49225T-HN that one morning suddenly got stuck rebooting it seems. It won't completely reboot, as it doesn't go through the initial movement of the camera that it does when powering up, but you can hear it click at regular intervals, see the lens zoom in/out, and if I ping it, it...

I have a Dahua SD49225T-HN ptz camera that stopped working overnight. I want to find the UART port and I see in your photographs that it is similar to the pins on your camera, but when I connect the ubs-ttl to it, nothing appears on it. monitor. My question is, what voltages do the Rx and TX...

We will be waiting for information on any news that will help us solve the problem with those cameras. :)

I have a question, have you managed or tried to connect to the uart port through a usb-ttl to the camera?

My interest is to know if someone managed to connect the computer to the UART port of the camera to see if the firmware can be updated through TFTP and UART.

Thank you for your response, I have been reading the forums and I see that many comment on the same problem that I have but none of them have solved it. I want to know if someone was able to connect to the UART port of the camera through some USB-TTL to check if my camera is alive or not-

thanks for your answer, All the time I have used a 12V at 3A power supply I don't know if I can interpret that the camera has damaged firmware. When connecting the power source to the camera, the Ethernet LEDs work after 5 seconds but after another 10 seconds they turn off and restart in a...

It's the same problem that happens to me, did you have a solution with the camera? found the problem?
