You do know that it is still available on their FTP site...? DS-76xxNI-SE(P) USA Firmware_v2.3.9_140820.zip

mmm that doesn't sound too good..! I can understand the 5.1.6 camera firmware going AWOL as it seemed to introduce several broken features. Maybe the 3.0.8 NVR firmware went for similar reasons. I would not have liked to have tried to force the update with the TFTP tool, as that would have been the last resort. Instead I'll just keep to the US 2.3.9 version.

From what I've seen I think that they have removed this firmware from their site..? When I tried to flash it it failed each time through the browser and when trying directly from the NVR I got "not enough flash memory".

On my ACTi 3MP domes I set: Encoder Type: H.264 H.264 Profile: High Profile Resolution: N2048X1536 Frame Rate: 15 Video Bit Rate Mode: Constant Bit Rate Video Max Bit Rate: Unlimited Video Bit Rate: 6M Question: Is the video bit rate setting @ 6M overkill in your opinion? Should I lower it to 4M? Two of my six cameras have the same resolution as you and frame rate, I use 4M for their CBR. I use the above resolution as the aspect ratio suits the intended area of coverage better than 1080p. Also the covered area is fairly constant in what it records, except if there were intruders or family members etc present. Thus a high bit rate, to capture lots of scene changes, is not necessary. My other four cameras are set to 1080p and use CBR of 4M with the same frame rate. The reduced resolution has the same bit rate due to more movement and traffic etc being recorded.

I have the Hikvision tools noted and both run fine under Windows 8.1. Nothing special was installed prior or since.

It seems that this bit is new.... Added Smart Search in playback full screen. Also Support remote client software iVMS-4200 smart search. and In NVR “File Management” local menu, optimized “Quick Export” function to be able to export video by specific time section.

As I needed six cameras I knew that the NVR I chose only had four POE connections at the back but allowed a total of eight cameras to be connected. I did not wish to spend the money on the 16 channel Hikvision NVR as it was too costly, even though the increased bandwidth and four extra POE ports might have been useful. Also I wasn't sure how "good" the POE aspect of the NVR was at delivering power and how it could be "managed" compared to the features on my managed 8 port switch. I had read a thread expressing some concerns over the POE module used in the Hikvision NVR's, not sure how valid that was though. Only once one of my cameras became not accessible with an abnormal network error. Rather than go into the loft etc or outside and up a ladder I just used the web interface for the POE Switch and turned off its power to that cam and thus invoked a reboot, this, thankfully, brought it back to life. Little things like that warm me to the switch. I could have injected the power to each camera differently to POE but to be frank my analogue system was a mess of wiring and many PSU's etc and one important factor for me was to simplify and tidy it all up. I bought the managed Netgear 8 port POE switch so that it will supply power to all of my cams (six) and then the last two ports being used for the NVR directly (LAN port) and the final port for my internal network, connected to a different Switch. They seem to draw 32w in total when the IR are on at night so there is still spare capacity there. Doing it the way I did means that the NVR to the Netgear POE switch is a straight connection and thus has no impact on my LAN, unless I am accessing the cameras etc. Finally not needing the NVR close to where the wires of the camera enter the building allows me to hide the NVR wherever I wish as they are connected directly via that POE switch and thus only need a single (and not six) Ethernet connection. I do not consider security to be a concern with my set up. Still not sure why you would want a different subnet as you have your set up...?

All six of my cameras are connected to a Netgear 8 port POE switch. I have not used any of the POE ports on the NVR. I have manually assigned each of the IP addresses (inc subnet) and gateways etc for each of the devices using the SADP utility. Why do you not use that tool to assign them with the same subnet as the NVR...?

It is annoying when I seem to be able to capture a potted plant swaying a fraction but then miss a person walking by...! Or that some activity is clipped due to anomalies in the consistency with the motion detection. I have only one disk in my NVR, a WD 4TB purple. With the system being quite new it has not yet filled up. But, like you, I have got the ability for 24/7 recording and the bandwidth calculator shows that I'm just at the edge of what is claimed to be support for the NVR. The free space showing as 0 might be "right" but it is less than useful once the disk as filled up for the first time. The motion detection anomalies do not seem new to me as my analogue systems would also have this issue. The missing motion capture aspect of either my previous systems or this Hikvision set up could not be entirely trusted for reliability in having just motion recordings. I just like them as they flag the recordings with "markers" which have some use when reviewing recordings. Hence my reasoning, if you prefer to use the time-line aspect of the web interface, for the motion detection flags to be shown on the otherwise solid blue time-line.

When I initially tried the 2.39 beta I had three of my cams updated to the 5.20 firmware and three were still in the post. So it worked fine. Since then I have connected the newly arrived cams (all 5.16) and downgraded the 5.20 cams and all remains well. So I have all six cams working fine with the 2.39 beta and 5.16 firmware on my cams. Not a straight forward install, as such, but great that you have got your cams working and some consideration might need to be given to the camera firmware, as you note. Any reason you have remained with that firmware for your cams...?

I think that Ill hold back a little as the 2.39 beta seems to work fine with all of my six cameras (5.16 firmware) and I don't feel like changing over to the 5.20 just to test out this firmware for the NVR. I have just downgraded three of the cams back to 5.16. Hope that you get your other three cams working without the need to "upgrade" them. Hopefully if others are feeling brave they will post back their results.

Ok thanks It does seem that you can still search for a motion detection event within the software iVMS-4200 Client, and download just those, rather than just the continuous recordings. But you don't seem to be able to get a timeline showing those motion detection events as I noted above. Anyway I have emailed Hikvision to ask their opinion.

Thanks for that, at least I know how, if I should ever want to, switch it off in a safe manner, goodness knows how I missed that dot The following is a fake mock up of what I would have liked..... the build up of what would be a solid blue bar indicating a continuous record and then segmented when tagged with a motion detection event. To me it seems pretty basic in what I would expect but I can't seem to achieve that. If it can't be tagged all that you would have is a solid blue timeline bar with no event tagging which makes it a little pointless when overviewing any timeline for triggered tagging etc. Any ideas on the bandwidth part of my question...? Many thanks

Hi I have a Hikvision DS-7608NI-SE/P NVR and I have flashed it with the 2.3.9 beta firmware. I have six Hikvision IP cameras connected to it and all seems well, learning various settings and configurations etc. At the moment I have each of the six cameras set up for motion recording. In the main it works well but even though the sensitivity is really good, recording the minimum of movements etc, there are times when it will either clip too much before a car or person has entered the frame or not recording enough for the duration of movement. I have set it to record 5 (and then tried 10) seconds prior to the trigger and 30 seconds after but still it can be clipped. This used to be the case with my older analogue D1 type system and thus I moved to continuous recording but kept the motion detection recordings as well. With this Hikvision though, I am mainly using the web interface to access it, if I have each camera set (just going to show Cam 1 as an example) to still pick up on the previously noted motion trigger (and to trigger an event) this will no longer be shown in the timeline.... ....you can see the yellow marked segments as they represented motion detection recordings. But you can now see a solid blue bar which shows a continuous recording, even though there are individual motion events within that solid blue time period. What I am not able to do, or find, is to show or search for just motion detection recordings (or markers) from when the NVR is continuously recording. With my old analogue system and generic DVR I could use the CMS software to search by Alarm, Motion, period etc etc. Thus it was always possible to ensure that no motion events were missed being recorded and none were ever clipped. The timeline on that could show various markings or colours representing the triggers which caused the tagging. So is it possible to sho a timeline whilst might be blue and solid to indicate a continuous recrding but also indicate where a motion trigger was tagged.....? Also my six cams are set as follows.... ...so I should be ok as this is the maximum that the NVR can manage, in terms of bandwidth. But if I did, for example, change two of the cams to 20fps it would then push the max to around 45mb/sec but as long as all six channels are not recording at the same time would that be acceptable or could that cause an issue...? It will accept those settings so I assume that they could be ok...? Last point I must be missing this but when I had an older 2.37 firmware installed on the NVR I found the power down option easy enough in the NVR menu but for the life of me I can't find it again...?! Thanks for any advice
