    Dahua NVR 5216-16P FTP upload weirdness

    Same here. It gets stuck uploading the same dav file again and again, even though it has been uploaded successfully before. If I remove the uploaded file, it does upload it again and keeps uploading it all over again. I had the problem on 215 firmware then on 216. Although on 216 at least it...

    NVR5XXX-4KS2 latest new firmware.

    I am running this new firmware (216) and it seems to be fine. I've switched back and forth 215<->216 at least twice, so it should be all right for you to test it - you can revert back. From new features I've noticed secure ftp, which did not work for me. The main reason that I upgraded was...

    Dahua DHI-NVR4208-8P - how to downgrade firmware

    Try downloading again maybe. Btw the bin file is actually a zip. If you change the extension to .zip you will be able ti verify integrity with WinRar or similar tools.

    Dahua DHI-NVR4208-8P - how to downgrade firmware

    My NVR5216-4KS2 allows downgrading and I've done it a few times. Furthermore going from V3.216 to V3.215 did not require config restore.

    Gmail. Dahua NVR.

    For you it is sending test emails periodically. Untick Health Enable to disable that.

    Gmail. Dahua NVR.

    Another piece of advice: don't use your normal gmail account, but open a new one specially for the task. This way you are not going to compromise security by giving your password to a chinese company, that no-one knows what is capable for. You can set up forwarding to your normal account if you...

    Gmail. Dahua NVR.

    I send emails to gmail with pictures from the NVR (NVR5216-4KS2). Although it does not work very robustly - sometimes the emails do not have pictures attached. I've found it handy to setup a filter so that the emails get deleted on arrival. If I want the check something they are stored for 30...

    Best practice for Time Sync/NTP on Dahua NVR and all the cameras

    I seem to have it working. If I manually set wrong time either on cameras on NVR, with time it gets corrected.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    On my NVR (NVR5216-4KS2) it is certainly possible. You can set the PTZ to go to a preset on idle, and add a timed task to do a tour. Not sure if you can do this on the camera alone.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Did the brand new cable help? Just far fetched things to try: is your mains voltage within 10% of the norm? Don't you have devices with high interference by the cable?

    Best practice for Time Sync/NTP on Dahua NVR and all the cameras

    Can you please explain why you need to sync time to NVR manually? Because my setup, which is sync NVR with NTP, and sync all cameras on a signal from NVR, seems to work fine. Thanks.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    It seems there is no Russian firmware for the camera (by looking at dahua website). You can PM me in Russian, I have this camera.

    Smart Codec.

    I don't know, sorry. I would not exclude they mixed up TB and GB and used different conventions, such as 1024 vs 1000.

    Smart Codec.

    I don't use smart PSS. I tried, but I find web interface to be better. As for storage. I don't understand you question well. But here is what I have. I have 5 cameras, one of them (PTZ) is set to record permanently, the other 4 only on events. I don't use smart codec (IVS will not work with...

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    No. This camera does not support auto-tracking, AFAIK. Instead, as the subject switches from zone to zone the NVR redirects the PTZ, thus achieving tracking.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    Yes, that's the idea. I have around 15 zones where PTZ looks at when other cameras spot something moving there.

    Dahua 2MP 25x Starlight IR PTZ Network Camera (SD49225T-HN)

    I am one happy user of the PTZ. I've bought 4 fixed starlight (two starlights, and two starviz's, to be more precise) turrets for spotting and one such PTZ for resolving faces and numberplates. It worked out well. I did not have any prior experience but reading this forum allowed me to make a...

    Thanks a lot! That Smart Player is buggy as hell unfortunately, but it does play videos with sound unlike my current method.

    How to convert dav files?

    My Dahua NVR sends (via ftp) videos to a remote location in dav format. I can watch them with Media Player Classic, but haven't found a way to convert them into a more user friendly format. Has anybody? Thanks.

    Easiest Way to Secure Camera System

    Sorry if this has already been mentioned. One simple solution for network security is to ban all outgoing packets from cameras and Nvr IP adresses in you router. Incoming packets are not allowed by the router by default.

    Finding a NVR

    Andy price matched a list of things I wanted to buy from Ali, totalling 1050$. Fast shipment and a good reputation make this the best choice. However, Andy did not match some other things I wanted to buy (two starlights I boughtherefor 139$ and lots of fixtures) totalling to 430$, so I went to...

    Important! About dahua hacked Chinese cams and NVR issues

    Just looked, there are indeed lots of those 4MP starlights on aliexpress dead cheap. Everyone needs to do their due diligence. This time I've selected a grand worth of cameras on Aliexpress, but in the end decided to buy them from Andy. But I don't think those vendors I chose would be a problem.

    Important! About dahua hacked Chinese cams and NVR issues

    I've been buying from AliExpress for a few years (around 30 or so items bought), and not once I ran into a bad sale or a scam. The rules I use are: -There should be good feedback from previous buyers of the item, the more the better. -The store should have been around for a reasonably long time...

    Important! About dahua hacked Chinese cams and NVR issues

    The very first post says that you should search the Dahua website for a particular model you see on AliExpress. If you don't see the model there it is a hack or whatever - don't buy it.
