Just be careful with these firmwares. They are NOT NTSC, they are PAL.

I don't think I would like to go back to a previous firmware version on the camera. It was unstable and needed constant rebooting. In addition, I don't think that upgrading the firmware on the camera caused the NVR to lose a feature I had. If anything, that would be caused by an NVR firmware upgrade. What I am saying is that when I enabled both the main and the substreams recording simultaneously, I was on an older NVR firmware. After I upgraded the NVR firmware, the settings remained and I was still able to record main and sub simultaneously. If the newer NVR firmware does not allow simultaneous main and sub recordings, the only way it could've been enabled is because it was carried over from the older NVR firmware, since I enabled it prior to the NVR firmware upgrade. However, when I had to turn off recording in the NVR due to the camera's firmware upgrade, then the restriction on the NVR kicked in and now it no longer allows me to turn both main and sub recording at the same time. I wish there was a way to hack it. On a different note, there might be a way to do this by adding a second hard drive to the NVR. I see there are different settings for where the main and sub streams should be recorded, like HDD1 versus HDD2. I would have to play with that.

When I initially setup my Dahua NVR 4208 with six Dahua HFW4300S cameras, I enabled substream recording so I had both streams being recorded, and I did this in the "Record Control" settings, by setting the main stream and the sub stream to "Auto" for all cameras. After that I was able to go back in the recordings and watch either the main stream or the substream from any camera. I need to have both streams because when I travel sometimes I am in areas where I have a slow network connection and if I want to see the recordings the only thing that works is the substream. I have my main stream set at 4096kbps 1080P and the substream at 1024kbps 704x480, both at 24fps. Of course, in live view, I have access to both main and sub streams so that's not an issue. However, in recordings I also need both main and sub streams. Recently, I upgraded the firmware in one of the cameras, and before you can load the firmware through the NVR web interface, you have to turn off all recording in the "Record Control" settings. After upgrading the firmware for the one camera, I tried to re-enable recording as I had it before. However, this time, the NVR refuses to enable both main and substream recording at the same time. It gives me an error stating that both streams cannot be recorded at the same time. This makes no sense as I had it working before. Upgrading the firmware in one camera should have nothing to do with this. I've tested just enabling main and sub recording for just one camera that has not been upgraded, and still, the NVR refuses to let me do the same thing it allowed me in the past. Does anyone here have both main and sub streams recording enabled at the same time? Thanks.

Do the IPC-HFW4300S and the IPC-HFW4300S-V2 use the same firmware?

I have not tried that. However, I have made comparisons with my other cameras, and I have found that only 3 of the 6 cameras will go blank consistently. I've also found that the 3 that go blank have an older firmware than the rest. I got a dealer to give me the firmware upgrade for one camera and I just upgraded it, and now it seems fine. However, they tell me they don't have the firmware for the other two. I have asked a few other dealers in Amazon and they give me the same answer. Does anyone know which dealer will have the firmware for the HDW4300S and HFW4300S-V2? Thanks...

My surveillance system has 6 Dahua IPC-HFW4300S cameras and a Dahua NVR4208-8P PoE NVR. Sometimes randomly some cameras will go blank and there is no way to bring them back to life unless the camera is disconnected from the ethernet and reconnected (essentially a hard reboot). It looks like the NVR sees they are there, but no video stream is delivered. I am trying to find a way to reboot the camera that is down remotely when this happens instead of rebooting the NVR. When rebooting the NVR, all cameras are rebooted, therefore the issue is temporarily resolved. Since this happens at least once a day, I don't want to have to reboot the NVR daily whenever this happens. The NVR doesn't seem to have a way to autorecover individual cameras by powercycling the PoE port where the failed camera is connected. I have explored the idea of having a managed PoE switch to remotely cut off power to the failed camera, but I've also thought about if there is a way to telnet into the Linux OS in the NVR and tell individual ports to shutdown, or perhaps a way to directly telnet into a camera or send a command to a camera to reboot. Does anyone know a way of doing this? As I said before, the NVR appears to detect the camera even if it goes down, so the camera must be responding to ethernet commands. Thanks!
