Pretty sad. I have 18 dahua, 2 hikvision cams and most I have hell with continuous sd card recording. I have 6 wyze cams that have no sd card issues after 2 years. Given, the data transfer rate is likely much higher with the high resolution dahua cameras, but they should bump up processor power...

It would simplify things a bunch of you could reassign static ip addresses to those two cameras within the same subnet, and then manually configure port forwarding in your router for the http port of the camera.. that's the way i usually do it, but I'm sure someone more experienced here will...

Let me know if you try them, and if they perform any better. I usually give them about 6 months use before I make a judgment. Usually that's long enough to have a failure or two. I'm just wondering if the blame is the cards, or could the cameras own read write system be causing the errors? I...

I've found a new card to try, specifically for surveillance cameras. Although I'm currently using SanDisk cards designed for the same purpose, I've always used WD purple drives in my NVR. maybe their sd cards will perform too. Here's a link so you can read the specs...

I've been having these issues for years. I've tried the most recommended cards, I've tried the most durable "continuous write" capable cards, but they all eventually just stop recording. The cards then cannot be accessed until formatted. I have cards in multiple PTZ's, turrets, and bullet...

I shut mine off a week after installing it. I was getting better footage with stationary wide angle. Auto track was not only losing the target, but scanning far beyond the area I had intended to monitor. I have one that worked pretty well out of four, but I just gave up after adjustments weren't...

The auto tracking is all done within the cameras software onboard, and as far as I know, it's either on or off, and controlled through the cameras local GUI, using it's assigned web address. Sent from my SM-N960U using Tapatalk

I do like the thought of being able to speak to employees.. but never had much luck with two way audio on dahua cameras. Sent from my SM-N960U using Tapatalk

I think only HNI models support auto tracking. I don't think HNR support auto tracking. Sent from my SM-N960U using Tapatalk

There are very cheap add on microphones out there, but the annoying thing is they need they're own 12vdc power supply. I don't understand why they produce these cameras with line in audio, but don't provide a dc output to power the mic. It would be such a simple thing to add. Sent from my...

That was a good suggestion. I had forgotten that I have noise reduction turned off on all my cameras, mic volume set at 100. But you mentioned that you only hear fuzz, or I'm assuming you meant white noise. The only thing I could guess is your source wasn't saved as internal mic, but maybe line...

Yes, you should be able to hear audio thru either the monitor connected to your NVR, or through the mobile app. Sent from my SM-N960U using Tapatalk

That model doesn't come up as a valid model Sent from my SM-N960U using Tapatalk

Oh, your audio has to be enabled in the NVR settings as well for each individual camera. Kevin Sent from my SM-N960U using Tapatalk

The audio is carried over the ethernet cable as well. If you have it enabled on your camera's settings, volume up high enough, and you still can't hear, check if your camera has built in mic or requires an external microphone. Sent from my SM-N960U using Tapatalk

Remote monitoring is pretty seamless if using one of the newer cameras with the barcode setup with IMOU or whatever they call the app now. If not it's still easy to setup with port forwarding and gdmss(idmss for apple). Sent from my SM-N960U using Tapatalk

I've been reading and narrowed down to two models, the NVR608-32-4KS2 (ultra series, no H.265+) and the NVR5832-4KS2 (PRO series with h.265+ support) the ultra series had dual core Intel vs quad core arm in the pro, and few other features. My main issue is with the absence of h.265+ in the...

Thank you sir, I'll definitely pick a few up! Sent from my SM-N960U using Tapatalk

I have about 18 Dahua cameras and six recording to SD card to record motion events only. Eventually all cards stop recording, and are not even showing up. All cards have been tested and the only way I have found to get them working again is to get out the bucket truck, go to each pole camera...

Thanks for the mod pics, by the way. Very useful! Sent from my SM-N920V using Tapatalk

I never understood why there was no 12 volt pigtail added for convenience of adding an external microphone. Just seems like a no brainer that there is a line level audio input plug, but no means to power a mic other than using a second power source. I just makes no sense. Sent from my SM-N920V...

Don't use Ubiquiti poe injectors on anything but Ubiquiti devices. They run different voltages.. Sent from my SM-N920V using Tapatalk

Check your network card properties to see what your network subnet is, make sure the camera ip addresses fall within the subnet range specified by your network card settings. This is something that took me forever to figure out. I was paying a networking guy for a couple years until I figured it...

Timers and schedules are setup within the camera web gui. There should be a tab for setting time related b/w or color using ir cut, or left to be controlled by light levels. Sent from my SM-N920V using Tapatalk

Anxious to see a reply.. I have to randomly remove, reformat my sd cards and reinstall them. It's a pain in the ass! One I have installed in a ptz mounted @50' on a telephone pole, which requires a bucket truck to resolve each time.. I have around 18 cameras with sd cards installed. Only about 4...

That's not your ir going on and off, that's your mechanical ir filter owning and closing. If you stand near the camera you can probably hear an audible click sound. You can try to adjust your day/night sensitivity but I'm guessing the light sensor or associated circuit has an issue. You can also...

I've found that anything above 4x causes larger video steps which would potentially skip over a short event. Maybe I need to update to newer dahua nvr. Or maybe just higher end. Sent from my SM-N920V using Tapatalk

I'd sure like to know what settings you use to make these captures.. Very cool! Sent from my SM-N920V using Tapatalk

Yep, it's still full of bugs. Sent from my SM-N920V using Tapatalk

Wired or wireless, as long as they're connected to the same network and properly configured on your nvr, it will be recorded the same as a wired device. Sent from my SM-N920V using Tapatalk
