    Dahua DVR - HDCVI Locking up

    Apologies for taking this long to reply back with an update. @bigredfish thank you for the links to the FW, I was able to update without bricking the DVR! After the firmware update, I thought all my problems were solved as for many weeks the DVR just worked again, it wasn't locking up anymore...

    HCVR7408L, which took me a while to figure out as GenIV Technology did everything they could to hide this. In the software it just says the model is HCVR

    Dahua DVR - HDCVI Locking up

    initially I would try to remote view and PSS couldn't connect, I would get to the DVR and viewing the TV connected to the HDMI port would show nothing, plugging/un-plugging the HDMI cable wouldn't bring it back - I'd have to power cycle to bring it back. Other times I have been home when it...

    Dahua DVR - HDCVI Locking up

    Well I thought I had this figured out but the DVR has been running with the ethernet cable disconnected for a few weeks and has locked up twice. There are no bread crumbs in the log files when this happens, the only thing I see is a 01 reboot code that happens when I have to cycle the power...

    Dahua DVR - HDCVI Locking up

    I turned off the port forwarding. I will do a factory reset as well. I remember now the last time I tried to find firmware it was a mess. I bought the DVR from GenIV Technology, they sent me to the dahua wiki which didn't have it. I contacted dahua where I was told I bought grey market as...

    Dahua DVR - HDCVI Locking up

    I don't have any reason other than to change one thing at a time? I will try to update the firmware on the DVR though it's so old I can't even find it on the dahua wiki.

    Dahua DVR - HDCVI Locking up

    2nd update: I replaced the power supply and hooked back up to the internet, locked up a day later :angry:!! Unplugged the ethernet cable and it hasn't shut down since, I have no idea what is going on, I don't see anything in the logs suggesting hacking but not sure what I should see? Is there...

    Dahua DVR - HDCVI Locking up

    Update: I reviewed the logs and see nothing to suggest a hacking. That being said, I unplugged the ethernet cable from the DVR and it ran fine for 4 days. I started thinking maybe this was the answer but then i heard the buzzer go off, the DVR had shutdown. Interesting though, it seemed to...

    Dahua DVR - HDCVI Locking up

    Good advice on the power supply, how can I check if I'm being hacked? I am port forwarding for remote monitoring.

    Dahua DVR - HDCVI Locking up

    1 - I can try that... what's the thinking behind this? 2 - yeah it's old... if I buy a new one though I would likely go NVR and IP cameras so not a cheap path but will do it if I have to 3 - I have not replaced the power supply but I did replace the fan inside the power supply. It does not...

    Dahua DVR - HDCVI Locking up

    Hey all, I have an older Dahua HDCVI DVR that I got in 2014. It ran great for the last 10 years but is now having problem after problem. The main CPU fan started making noise and right before I had the parts to replace it was the first time the DVR locked up. It just seemed to be offline but...
