    DS-7608N-E2/8P not working with camera DS-2CD2512F-I and DS-2CD2143G2-I after firmware update

    @trempa92 - I searched and searched the web for answers to this problem and you helped me solve it! I have the same EOL NVR (DS-7608N-E2/8P) except SDAP shows it as DS-7608Nl-EV2/8P, and I couldn't get two DS-2CD2143G2-I cameras to appear on the monitor. The NVR detects it but I kept getting an...

    Hikvision ERT-K204, 4-Channel DVR - Looking for firmware

    Nevermind. I reached out to Hikvision support, provided them the XML 'exported' file from SADP, received an email with the XML unlock file to reset the password. Done.

    Need help with RS232 pin-outs for DVR - HCVR5108H (OEM version, no Dahua logo) Mini 1U HDCVI

    It does not boot w/o a drive and I tried using a different 12V, 2A power adapter as well. It powers on with a solid red light on LED4 and no POST beeps from the mini speaker.

    Need help with RS232 pin-outs for DVR - HCVR5108H (OEM version, no Dahua logo) Mini 1U HDCVI

    Last night I had only the white wire (Rx) connected to pin 2 (3.3V) and nothing else connected, not even GND and when I power on and off the DVR, PuTTY would start filling rows of blocks. So not sure if that is normal and it stops when I turn off the DVR which means pin 2 must be the (Tx) on the...

    Need help with RS232 pin-outs for DVR - HCVR5108H (OEM version, no Dahua logo) Mini 1U HDCVI

    @alastairstevenson Okay, so I concluded that the USB-TTL PL2303TA cable is working with a loopback test (connecting a piece of wire between RxD and TxD) in PuTTY 0.78, Termite 3.4, or MobaXterm 22.0 via local echo. So I guess this DVR is a goner unless there is anything else I could try?

Windows 10 recognizes the cable and assigns it COM3. The comm port was...

    Need help with RS232 pin-outs for DVR - HCVR5108H (OEM version, no Dahua logo) Mini 1U HDCVI

    Hello, I have a Dahua OEM DVR that won't boot or display anything on the monitor (black screen). I see a red light on the main board where it marked LED4, so I suspect something is wrong with the firmware or programming. I read somewhere that I may have a chance to revive it with RS232, but I...
