Ubnt EdgeRouter Pro with a couple of UAP-AC-PRO Wi-Fi access points.

This happens when you use more than one interface to control settings. For example Synology SS, iVMS and camera (browser based) UI. Also, if using Synology SS, there is an option of preserving camera settings.

You don't really need any Hikvision tools. All cameras have pretty good web interface that you can use to manage all features. No need to litter your machine... :)

Looking at the specs for DS-7608NI-SE/P, there are apparently versions that have only 4 POE ports. Does this one have 4 or 8?

Would this NVR work well with five 3M cams? Does it require US versions of cameras? I have 5 Hikvision DS-2CD2032-I cameras (four with V5.2.0 build 140721, one V5.2.5 build 141201) all are originally Chinese editions flashed to English (intl) firmware. Will this be a problem?

To get a better night vision you would have to significantly increase your budget :) 3Mbps Hikvisions are about $100 so you cannot expect very good low light performance without some help (more light) You could get a spot or flood IR lamp.

I would just run CAT 5e or 6 cable and use POE for power.

Maybe I have the "49 day" special ones :) I'll keep an eye on this and report later.

Right unsigned int. I got four cameras that mysteriously froze within minutes of each other in the order they were plugged in... Just happened that a little over a month ago I replaced the POE switch. I setup a watch dog (Ubiquiti TS-8-PRO switch) to bounce the power if it doesn't get reply.

Ok. A little over 49 days would make sense. It seems like there is something overflowing in the software. It just happens that unsigned long can hold number of milliseconds for about 49 days... I will set a watch dog and will know for sure (in 49 days :)

Have you guys had any problems with DS-2CD2032-I staying up for a long time? What is your longest uptime?

That's a different NVR...

Loud fans is not a problem since this will be in the attic. My main concern is that the cameras were originally Chinese firmware. Also, the spec for the NVR states 8 channels at 720p and 6 channels at 1080p. How about the 3M resolution? (The full resolution of DS-2CD2032-I)

I would like to replace my current NVR (Synology Surveillance Station) with Hikvision DS-7608NI-E2/8P-2TB (from bhphotovideo.com) and would like to get your opinions. I have 5 Hikvision DS-2CD2032-I cameras (four with V5.2.0 build 140721, one V5.2.5 build 141201) all are originally Chinese...

What you see is a motion blur caused by exposure time being too high. Set it to at least to 1/30 (gain 100%) If the image is too dark, you will need more light (maybe external IR illuminator)

For now, I'm leaving it at 8 fps / 8 i-frame and 4096 bps VBR. It is really a problem only at night. Seems there is really no good solution other than higher fps and higher bit rate.

Firmware is 5.2.0

My old settings were 4fps/4iframe at 4096bps. The quality was OK (no pulsating/judder) but I wanted a little more fps. After setting it to 8fps/8iframe I can see the judder. No matter what I set the fps/iframe, there is always some judder. The only way I was able to get rid of it was setting the...

One thing I noticed is that there is some "pulsating" in the stream. What do you guys set the Iframe interval to? With 10fps should it be set to 10?

Ok, looking at that, if I choose 8fps, the default bit rate (4096bps) should be plenty. Does that seem right?

I got a couple of 2CD2032 cameras and was wondering what settings to use. Mine are set to 10fps and VBR bitrate with max set at 8192.

Where can I get 5.2.3 and 5.2.5 Release notes? I have four cameras with 5.2.0 firmware and just got a new one with 5.2.5. Everything works fine for now but I would like to know what, if anything, changed.

I used TP-LINK TL-SG1008P for 4 Hikvision cameras with no problems even though it was in the attic (max temp I measured was ~125°F) I just replaced it with Ubiquiti TOUGHSwitch (TS-8-PRO) since I needed more POE ports. TOUGHSwitch is also rated for -25 to 55°C (-13 to 131° F)

Hikvision themselves list B&H as authorized resellers so it should not be a problem.

Just discovered that B&H is now an Authorized Reseller of Hikvision. For those looking for US warranty...

Depends on camera. I use "Intrusion detection." (Hikvision DS-2CD2032-I cameras) Motion detection was giving me many false alarms. Intrusion detection may not be available on all cameras.

I got TP-LINK TL-SG1008P switch. So far so good. I am more worried about the backup (APC BGE90M)

It was a pain in the butt :) All four cameras are connected to a POE switch in the attic. Will see how it will do with temperature swings...

I have DS713+ and I like it. Just updated to DSM 5.2 and thinking about upgrading hard drives. SurveillanceStation is OK, though more Windows friendly than I would like (running linux on my desktops) Good thing is that you get two camera licenses included.

All four are DS-2CD2032-I. For recording I am using Synology SurveillanceStation.
