Did you setup the IVS in the cams or in the NVR for the cams which don’t show the lines and boxes?

Hi i believe this Mod is for the normal fan, issue with the POE NVR is the fan within the PSU which is noisy.
Replacing the fan is not an issue but you still need to make sure it is still having enough circulation of air as before to avoid degrading of the NVR. I hope yours is OK as you are running a 5v fan and have even reduced it further.

For the NVR5216-4KS2 (without PoE ports) the power supply is an external brick, so the internal heat load is lessened (as is the noise). The fan header for the case fan that blows across the circuit board is 5v, which is why I used a 5v replacement fan. (Many 12v fans won't even start at this voltage, and those that do turn very slowly. Conversely, hooking a 5v fan to a 12v header will almost certainly result in smoke.) Between opening the side of the case to get smooth and unthrottled airflow through the fan and mounting the case to take advantage of convection, the unit is plenty cool.
Maybe Dahua has finally realized noisy fans are bad news. I noticed while browsing the Dahua International New Product section, they are releasing new versions (V2.0) of the NVR52/54/58xx series NVR's. Now they have a "Smart Fan" that will automatically adjust fan speed as needed. For most of us, our NVR is rarely under a heavy load, so hopefully the new versions will be much quieter. Too bad, it's too late for most of us already owning one of these.
I have the version 1 and mine already does this. When it’s 75 in my house the thing is loud as can be but when it’s 60 in my house the thing is near silent. The fan speed changes based on how hot it gets.

Hi @davw, I had exaclty the same issue and managed to get mine working again using an rs232 usb serial cable (very cheap), putty (free software to access the console via RS232) and TFTP server (more free software to expose the correct files for the NVR to be able to download them over your network). Where did you get your unit from? I bought mine on aliexpress but the seller is no help. Once I got mine up and running again, I tried other updates, but all have the same effect - it feels like I have a unit that will not update for some reason, maybe it's not meant for the UK market and has been altered by the seller to accept this firmware only.
I live near Manchester so not local enough to help, and if it's the same as mine, even if you get it running, you can never upgrade it, and the existing early firmware is buggy.
This is very helpful.
I have been looking at the 52 vs 54 myself.

After reading your post, I checked the specs. You are right, the 54 has 16 alarm inputs. I don't know how many I will want, but it's good to try and have more possible inputs than less, if the cost is only a little more.
I've been wondering this too, when looking at some of the NVR models.
OT: Going by your SN, do you have a dog?

I do not know what was causing it but I fixed it by uploading the firmware and hard reset it.
Cross-posting this question in this thread too.
What are different alarm conditions to consider?
One NVR has a 4 channel alarm, another has a 16 channel alarm.
I don't know if 4 alarms is good, or more.
I have discovered an issue with the NVR5216-4KS2 and email timestamps on IVS and Motion notifications. I had this last year but frankly was too busy to look into it and it ended when daylight savings time ended. This year once daylight savings time started up, it came back (for reference, I am in US Central Time). The emails I receive with screenshots contain the correct time in the "Alarm Start Time" text in the body of the email and image timestamp of the email (correctly adjusted for daylight savings time), however the actual mail message shows up in my inbox with a timestamp one hour ahead of the correct time. The odd thing is that I only notice this in using Mozilla Thunderbird for an email client. I get the correct timestamps everywhere in Mac Mail and iOS Mail on my phone. Initially I struck this up to be a Thunderbird bug but now I do not think so. Reviewing the email headers, all of the "Received:" and "Delivery-date:" headers are showing the correct daylight savings time offset of -500 for US Central Daylight Savings Time, however the "Date:" header shows a -600 which is standard central time, not daylight savings time. I believe the root of this is that the NVR is incorrectly still sending the email with the non-daylight savings time offset in the "Date:" header - and then the difference in mail clients I am seeing is that each of them keys the message timestamp off of a different header. @EMPIRETECANDY - Can you report this for us to Dahua to see if they can get this resolved in a future firmware? Or is there a newer firmware available that may have already addressed this?
Thanks for the reply. I get that is a workaround, but it is far from ideal. I'd be more tempted to switch email clients. The thing is - automatic DST switching works great for me everywhere in the NVR and cams but here. Well - one other location has issues - the Mac version of SmartPSS is all correct except for when exporting video, that is off by an hour during DST. In this case though, I believe I have identified the email header involved so hopefully that can lead to a fix. Should be rather simple and I am hoping Andy can pass this along to them.
@EMPIRETECANDY - Is there by chance a newer build of the Mac SmartPSS software on the horizon?
First, I just stumbled across this forum as I was researching Dahua NVRs. Whata great wealth of info on this forum and I have been trying to read as many threads as I can, but it is hard to get at all the info I need. I am in the US and was looking at Amcrest (they OEM Dahua) and was not impressed with the NVR selection. I am leaning toward the NVR5216-4KS2 from @EMPIRETECANDY and had a few questions, please bear with me as I am new to IP Cameras.
I do not need on-board POE as I picked up a Netgear GS724TPv2 which is a sweet switch. This will allow me to do some VLANs I have been wanting to do for a while now. I wanted a 16 channel NVR as I plan to grow into it after the initial 6-8 cameras.
I picked up some Amcrest cameras a while back to do some initial planning on cam style, placement and resolutions. Will these work on the Dahua non-logo NVR5216-4KS2 or will I lose motion detection and such?
Because of the 1-2 week lead time I was planning on getting the NVR to try for a bit with the Amcrest cameras and then maybe buy some Dahau or more Amcrest cams.
Since the NVR5216-4KS2 does not have POE how noising is the NVR itself? I was going to put it in a media cabinet that has some airflow, but don't want a loud fan distracting to people in the room.
Since it is running Linux, can I put like a Logitech wireless mouse to I can manage the DVR from across the room?
I see some links to firmware and the Smart PSS on this forum, but none of them works, where can I find Smart PSS?
How successful have folks been with adding non-Dahua cameras in general to these non-logo NVRs?
Thanks in advance for your help!
