Hi there, this is my first post although the site has been helpful as a visitor. I have a Dahua NVR3104H-P that has many features missing, like Search and motion detection and want to upgrade the firmware. Presently 2.610.0000.7 to General_NVR3xxx_Eng_P_V2.616.0000.6.R.20140507 I have read through many posts and YouTube that simple say go into the Upgrade menu and Start, very often mentioning a .BIN file, and occasionally an .IMG file. I have found many sites with newer .BIN files , sometimes in a ZIP file, but no .IMG files. The NVR does not recognise the .BIN file, it just gives error "open file failed" Do I need a .IMG file instead? and where do I get one, or how do I make one? Why are there all these available .BIN files if they do not work? Sorry, a lot of questions. Any help welcomed. Regards Tom

Hi I,ve tried it with Regular and MD, only regular, only MD and it still will not find motions in a search. I've spend enough time on this problem - I'm just going to live with for the moment. I certainly won't buy Dahua again - their support is terrible. Thank you tomcctv for your input. Regards Tom

Hi TomCCTV The case is the 1 unit black box - all squared off corners. The GUI is the same except it has another parameter ( 2nd line ) under Channel ANR 1800 sec a Box to enable I don't know what ANR is 1800 is the default the box is not enabled Regards Tom

Hi tomcctv, or anybody else that's interested. Using running man - go into search - select full screen(it does not work in multiscreen) and play, running man goes from grey to black - click on man and the screen give a grid that you can select an area - then click on man again and it should search for all the motion detections. But it comes up with " There is no motion data in the current region" I select Motion Detection in Settins/Detect - Enable - click region and select the full screen I've tried a combination of Manual recording, scheduled and Motion Detect, but no luck. On my DVR I just have to set to manual record and set the region, and it works fine. Trying to plough through a 270 page PDF is no fun and it's disconcerting when it says something like " some features may not be relevant" , but doesn't tell you which features or which model. Testing my DVR for motion detect is easy as it has a test button when setting the motion area and a led on the front panel when a channel is recording, neither are on the NVR. It looks like the only way I can tell if there is a motion detection is makie up an output alarm, if I can figure that out - again the instructions are not very good. I was wondering what you found in those documents TOMCCTV Regards Tom Wood

Hi tomccty I tried a clean 1MB pen - still the same. I was looking through the many files that I had downloaded, including bin, img, and zip. I found a zip file which when unzipped gave a file called update.bin. This file was exactly the same size as a 2.610 bin file, so I changed the name of General_NVR3xxx_Eng_P_V2.616.0000.6.R.20140507.bin to UPDATE.BIN Using this I now have a NVR with Version 2.616.0000.6 !! The search can now be activated. although it never finds anything. So the motion detect is not working. I will look at that tomorrow. Regards Tom

I've used 512MB 1GB 4GB all the same result - the file is only 15KB

The run man ia always greyed out - cannot activate it - and this is on full screen - I know that it does not work on multi-screen. I copy the BIN file to usb stick - go into VERSION - Upgrade - click on this give an error "open file failed" Of course this could be because I have the wrong type of file, which is what I have been asking about. This fails with usb stick in front or back usb socket. I have noticed one thing. On the DVR "DETECT" menu there is a TEST button to to test the motion area that has been set, which is very handy. On the NVR there is no TEST button, so I cannot be sure if the motion detection is working. Regards Tom

I would always upgrade directly from the actual unit. The files I have found are like -: General_NVR3xxx_Eng_P_V2.616.0000.6.R.20140507.bin The running man icon is there but greyed out.

I have upgraded firmware on lots of equipment many times - the Dahua instructions are useless - I just need some guidance on the file to use. The IS a reason to upgrade it. The notes for 2.616.0000.0 says it adds " Support smart search for function when playback" which is what I want. I have a Dahua DVR and have no trouble setting up motion detect and search on that - and it is the same GUI.

Hi, I'm Tom from UK, newly registered, but the site has been very useful as a visitor, thanks to you guys. I have been using CCTV for about 3 years for domestic use. I originally had a Dahua DVR, but then bought a Dahua NVR for better resolution.
