Oh... With five cameras running so far, CPU is at ~10% and RAM 1.30GB.

So, the pc came in early, on Friday, instead of Monday. Did a fresh install of Win10. Installed the 2nd NIC. PC on 192.168.1.XX side and cameras on 10.1.1.XX side. Got BlueIris up and running. Upgraded all the cameras firmware, restored to factory, and started fresh. New, strong...

I just kept hitting buttons until something happened. :) Upgrading the firmware gave me the "factory default" option. I'm guessing the old firmware expected you to use the mechanical button for factory reset. Thanks!!!

Yes, all Dahua cams. Sorry. Mine is different from yours. No "factory default".

I've tried searching. I'm betting I just don't understand... When I connect directly from computer to camera(s), connect via web, go to setup, system, default, and hit the default button... Get warning "Are you sure to reset default config?" Hit Yes. Camera (seems to) reboot. But, I can't...

Yes, of course it does. And I'm an idiot. :) Tried to cancel. If not, I'll return. Geesh....

Just ordered another ethernet card (for a total of two, one for the camera's network), SSD, and 16 port poe switch. I'm fairly confident I want the cameras on their own network - replicating what my broken Dahua NVR (NVR5216-16P-4KS2) used to do. Seems more secure that way... making sure the...

Done. It'll be here Monday. THANK YOU!!!'

OK, I think I'm just going to buy this one off ebay. Dell Optiplex 9020 MT i7-4790 3.60GHz 8GB DDR3 500GB Win 10 Pro - $280 Should I plan on reinstalling the OS, for security purposes? Anything else I should think about re: buying off ebay (never done it before)? I really appreciate...

Yeah, I'm still obsessing, like an idiot. I take it this would be silly/overkill/inefficient? (from DellRefurbished) $440 shipped... Dell Precision 5000 Series (5810) Processor: Intel Xeon Quad Core (E5-1603 v3) 2.80 GHz Memory: 8 GB Hard Drive: 500 GB OS: Windows 8.1 Professional Chassis: Tower

I haven't yet been able to find an answer... Is external storage OK with Blue Iris? Like SSD internally for OS and 1 or 2 purple drive externally for the video? This seems basic, but I haven't found an answer yet in my googling...

Thanks. I just realized I'd be limited with drive space as well. Looking for something bigger than SFF...

Thanks guys! Sorry, I knew better... Should have added cameras... I have qty5 2MP (starlight) and qty3 3MP (K-series) - all Dahua. Might add a couple more 2MP starlights sometime in the future... Maybe???

Been trying to research. It seems the processor on this is "OK". Replacing a broken Dahua NVR. Would add an SSD, 4GB memory, 2nd ethernet card, Win10, and 2 purple drives (if they fit - already have 1). Price shipped is just $140. Dell OptiPlex 7010 (dell refurbished gradeA) Processor: Intel...

FWIW, no port forwarding either.

I hadn't considered it being hacked. Interesting... I haven't noticed any thing weird (like a new userid, per linked article). My router blocks all traffic to/from the NVR & WAN. Also, I've never had any of network options enabled - my goal being to keep the thing locked down as best I...

NVR5216-16P-4KS2. About 2 years old. I've been messing with this thing for a week now. Tried everything, in every combination, I can think of. Unplugged all cameras, plugged all cameras in, plugged NVR into different switch, removed NVR from any network, tried multiple computers, etc...

Is there any way to force a factory reset from the motherboard? Thanks!!

Just for fun, I tried upgrading the firmware from the config (mac) tool. It fails also. I did get a warning that login failed. So, I'm wondering if my user account might be keeping me from upgrading/factory resetting? I thought about trying to login with the 888888, but the only option I have...

Well,, I've rebooted several times. And physically cut the power a few times. But, since I'm not sure what a clean state is, I'm betting I'm doing something wrong? Any way you could elaborate a bit? Or is there a place I can educate myself? I've searched, but not really found anything yet...

My NVR5216-16P-4KS2 has been acting wonky, so I wanted to start over. From the NVR (& mouse), I tried doing a factory reset. It fails. I've tried upgrading my firmware from 3.210 to 3.216 - from the NVR console (memory key) and SmartPSS (mac). Everything fails. I'm betting this is user...

I really appreciate the help!! It's not one of the 16 POE ports. It's the other one, that's by itself. I can't really see behind it, to see if it's labeled...

Router/pfSense>Unifi Switch8 60W>dumb switch>NVR+everything else. I haven't yet found a setting on the NVR that provides DHCP on this side of the network??? But, I'm hardly an expert. Super weird...

NVR5216-16P-4KS2 I just added some new Unifi equipment (managed switch, CloudKey, & access point). Each time they would boot, "some" would get bum IP addresses in the 192.168.0.XXX range - making it impossible to bring them into the network. My router is setup to give in the 192.168.1.XXX...

I've literally searched everywhere for a pinger on the NVR. And yet, there it was. :) I get a "Can not connect to the network", so that's good! I also noticed last night the pfSense firewall log shows it's blocking the NVR IP connecting to WAN IPs. Thanks for the tip!!

I'm fairly confident I blocked all inbound and all outbound traffic to the NVR static IP address. Been reading all afternoon and I "think" I got it right. I don't know how to ping from the NVR, or ping to the NVR from outside. So, I can't exactly confirm. I'm pretty sure I can do vlans with...

I have to believe this is basic and covered extensively, and I've searched, but I can't seem to find an answer... and, I'm not exactly well versed in things networking (but trying to learn). How do I know if my NVR is secure from the internet - nothing in or out? I have all the cameras...

Your post made me realize I should try rebooting my DVR. Sure enough, mine's working now. Newb.

Does anyone know if these work/are worth buying? Monitor and Find Everything from the Internet - Wireless Sensor Tags Looks neat. But I'm new to all of this stuff. :) Thought I'd ask here in case... Thanks, Skip

This is the only PTZ I have. NVR5216-16P-4KS2 with 3.210.0003.0, build 2017-4-18 - if that helps. Thanks, Skip
