So I have this Precision 7400 running full time with the Big GPU for folding. I’d like to install a couple of 2TB drives of the sort that are optimized for video recording and make a mirrored volume. Then I’d hang a few 1080p IP cameras here and there and get some application to manage them on the 7400. Is there an open source security camera management app that folks recommend? Would running that app require much overhead from the CPU? Any other thoughts or recommendations?

Here is a buffer image:

That CPU in your rig is older but should handle a few cameras without causing much of a problem.

Milestone has a free product that is decent, lets you run up to I think 8 cameras and is what I use.

BlueIris is another example that’s easier to use and more fully featured than the free milestone, I think a license costs $50.

Neither of those are open source, you have to wander over to Linux for that.

Not sure about free security camera software, but I can vote for Blue Iris software if you don’t mind going paid. I set it up for a local business and they like it a lot. Can’t remember the cost though.

8 camera feeds would be more than adequate. I’d probably max out at around 4. Do you think it necessary to buy drives that are specified to be DVR, or whatever?

Also, regarding Blue Iris, would the software have the motion detection feature or does that happen in the camera?

I’ve just ordered a 1080p IP camera from Amazon for about $60. It claims to be POE, but also comes with a little power supply. I’ll avoid buying POE switches or worrying about power inserters for the moment.

Can I use Cat 5 cable for this?

jminer says he thinks Blue Iris is $50 for the license. That is not above my shock threshold.

It’s been a while since I looked (few years) but as I recall the open source stuff was seriously lagging. Like, maybe it could multiplex, and MAYBE detect motion, but that was about where it cut off. It couldn’t understand how to prioritize keep vs delete, there was minimal if any cloud integration, it might not have even been able to handle audio. This is the sort of thing people only build to sell cameras.

Having worked in CCTV for a few summers, cheap commercial stuff is infinitely better than the top end residential. Pick a vendor that also sells high end products but scales back the features for smaller installations. As I recall, there’s a subsidiary of Honeywell that I was considering at the time. I’d have to look into the name.

Oh, also, a good 1080p camera is the absolute most you need. Even 720p is fine for a lot of applications. 4k is totally unnecessary, and I would question whether they’re better than 1080 anyways. Good vendors won’t sell stuff they aren’t prepared to stand behind so I’m not even sure they’ll offer a 4k camera in a lower price range.

No need to get drives specified for DVR, just any drive would be fine for you since you’ll be not putting/pulling much data from there. I just use a USB3 external 2TB drive on mine.

Blue Iris does VMD in the software but some cameras do it too which then the NVR software can pickup as an event or the camera can send you a notification too.

For cameras I usually buy a Dahua or Hikvision off of ebay for like $20-60 a camera depending on what I’m doing.

For Power if you’re going to do more than a camera or two it’ll probably be easier to pickup a cheap POE switch since it’ll make your cabling easier and you’ll need a switch anyway. This guy ’ll give you 4 POE ports and only costs $30.

CAT5e is the cable you likely want to use but CAT5 would be fine too, the cameras will only push a few mbs each, they wouldn’t even be throttled by 10mb ethernet.

You’ll probably also want to make your own ethernet cables, it’s actually pretty easy and the tools only cost a few bucks.

Sorry if I’m being too technical, this is actually what I do, just at an enterprise level.

I like to use 4mp Hikvision turrets with a wide FOV. They’re cheap and give you a great detailed image.

4k is definitely way to much for cameras, 1080 gives you most of what you want in a commercial setting unless you’re trying to capture faces.

Too technical?? Hardly. Don’t hold back. As for storage, I have four empty bays inside the case. Regarding storage, how many GB per camera per unit time should I allow?

 Also regarding storage, the last few machines that I have set up for myself, I have created mirrored volumes for storing bulky things. I thought I would do that again here. Any thoughts on that?

I am nervous about accessing that thing remotely. I suppose I could use TeamViewer... Remote access  is an entire frontier that I have not crossed.

That’s a pretty difficult question to answer since a lot of it depends. If you record the camera at 15 FPS with decent compression at 1080 without too much motion in the picture you can plan on it using ~25 gb a day storage. Here is a basic storage calculator that will help you gauge the storage you need.

Cameras that can compress at x265 can definitely save you some off that and more motion in a scene will cause it to take more. Since cameras heavily rely on compression the amount of pixels moving on the view will substantially change the amount of data it needs since it is sending more information.

Are you planning on recording 24/7 or based on motion detection? I’d recommend the 24/7 with alerts on motion.

I wouldn’t mirror data but you can create a RAID for them but with your motherboard being old I wouldn’t recommend that. It could do it, but when a motherboard fails that was running a RAID with it’s onboard controller it can be difficult to recover data. That being said using a RAID controller can help you not loose data if a drive fails. Something like 4x 2tb drives in a RAID 5 would give you 6tb of usable data while protecting you against data loss of 1 physical drive.

Remote access in the surveillance world usually means forwarding a port on your router so you can access the video from your home system on a mobile app.

Why not mirror for my simple needs?

jminer > Rusty Vandura - www.tinyurl.com/keepoppo 07/30/2020 at 22:05

Mirror would work to put your data on two drives protecting against the failure of one , I just don’t like it as it’s relatively wasteful since it takes 50% of your space away whereas a RAID 5 will give you both increased performance and only takes away 1 drive capacity. You do have to buy more drives with RAID 5 since it takes a minim of 3 drives to use though.

At the same time since we’re only talking surveillance camera data it’s not likely a big loss if you loose data. I store mine on an external USB drive. They’re super-cheap for the capacity and reliable enough. For t he internal drives in my server I also use shucked external drives as they’re way cheaper (while performing a little worse) than buying a bare internal drive.

I am running something called Shinobi on the very first raspberry pi 1 B+, headless, stream ing and copying h.264 compressed video since the pi has hardware for that. So far, only one camera but it’s at 10% CPU load and 50% memory. Shinobi and Linux can be a challenge, but it offers tons of flexibility from a browser based  interface.

 I chose 1080p because the camera that I bought on Amazon seemed pretty cheap and I was pretty sure that 1080p would be more than enough. The television in my living room is a 52-in plasma and everything I show on it is 720p and it looks great.

 Schucked? Haven't heard that term used that way with regard to drives before. I've shucked a few external drives in my day... I just thought I would buy a pair of two terabyte or four terabyte hard drives, whatever's cheap, mirror them, and then have some redundancy. It would be my luck that the one time I went to go look for something I'd caught on the cameras but the drive would have failed.

Then you should be good with mirroring. I picked up the term from the reddit data hoarders and home lab communities.

I can definitely help you with the port forwarding, the tricky part is your router, if it is the one the ISP gave you it might not allow it but if you bought your own then it’ll let you.

I don’t know what you mean by mirroring, do you mean simply “rsync” or similar the datas between two disks?

RAID1 is liteally mirroring.

To be fair, in the case of CCTV, loosing the data is usually not a real issue but if you want to have fun putting this together, why not :)

If you are not having a RAID card, using software RAID on Linux works perfectly fine, storage spaces on Windows is also working fine (but you can’t boot on it which is not a problem for your needs), if you are on a Mac, i don’ t know what is available.

You can also buy a RAID card, even an old one would suffice as you don’t need write cache/ fast operations for your need, keep in mind that base card don’t always support RAID other than 0/1 which, in case you would want to do a RAID 5 or 10 with 3 or 4 disks for example.

In any case, don’t use external drives and keep in mind that if it’s used to do CCTV, you will need an APC (if you don’t already have one), you will need to keep the computer on a safe place (it would be useless if its stolen) and/or synchronizing images/feeds to a distant location in close to real time .

I don’t believe anything gets uploaded to the cloud - you’d bd accessing your OWN server remotely from your own home’s IP address and a forwarded port through your router. You can disable that feature id you don’t need it, I believe.

Think of forwarded ports as a path for Data to take from outside your home network (i.e. the internet) through your router to inside your network.

Certain programs require certain outgoing or incoming ports to function, or for access. For example, I have all the PCs here at home set up for remote access so with the right IP address, I can access them all using VNC remote desktop software remotely.

I’m assuming you know what IP addresses are? (In really basic terms, think of them as like a ‘street address’ for your computer on the internet). I.E. my house could be 45 Smith Drive. Like the house address, your router would have an external IP address visible from the internet assigned to it by your Internet Service Provider, say 123.255.1.1 as an example. That is an IPv4 address and is the older, more common protocol - in IPV4, each section in an IP address can go up to a max number of 255, i.e. 255.255.255.255 or anything in between, i.e. 56.34.27.254. The other protocol is IPV6 but that’s less common and involves letters AND numbers, but the principal is the same. Ports are added to an IP address using a colon at the end, i.e. 56.34.27.254:8000. There are two types of Ports, but I honestly don’t know the difference between them enough to matter so I’ll tell you what they are but won’t go into detail about either...the two types are UDP and TCP but they use the same range of numbers and are assigned at the end of an IP address the same way.

That means if anybody (say, you) wants to to connect remotely to anything on your network, the external IP address is th they would use. One thing is, IP addresses can change at random as they are ‘leased’ to your device using a protocol called DHCP by your ISP and once that lease is up, it can assign you the same or a different one...though it usually tries to assign you the same one repeatedly. Changing IPs aren’t always the case because people can set a static IP address, which means it never changes, but that almost always doesn’t happen with a normal home internet connection and people just leave the IP as DHCP. Port numbers are added to the end of a

ANYWAY....ports...your home router receives an external IP address from your ISP, but there is a second level...your internal devices on your home network (smartphone, laptops, desktops, whatever) get THEIR IP addresses from your router...these almost always start with 192.168.....so say your laptop is 192.168.3.2. But.....you can’t see that address from the internet because it’s an internal IP address....so port forwarding is used to send a signal to that machine. Think of an internal IP as being like an apartment number in an apartment building....your apartment building might be 45 Smith Drive (the external IP) and you might be in Apartment 9 (internal IP), for a basic description. Ports are likekindof like the door or window you use to get into the building to that Apartment.

So, say I wanted to be able to remote into my laptop PC using the VNC remote desktop protocol from somewhere else. VNC often uses the port number 5900 to ‘listen’ for incoming signals. To set up a forward, I would need to know my router’s EXTERNAL IP address and whatever port number I chose to set up to access my laptop. Port numbers can range from 1-65535. You sign into the router and create a ‘Port forward’ which basically tells the router ‘if a request comes in on this port number to your external IP address, send that signal to this internal IP address’. So, to use the remote desktop example, say my external IP address was 123.123.12.12 and my laptop’s internal IP was 192.168.12.12. I can set up the port forward up in the router using a certain port type (UDP, TCP or both) to say if a signal comes in at 123.123.12.12:8765, send that signal to 192.168.12.12:5900.

So, if my laptop is on, and VNC is running, VNC would be listening for an incoming signal at port 5900, but it is listening to the router. The router would be looking for any signals coming in requesting port 8765 at it’s external address. With the port forward set up, if I send a signal to my router’s external IP at 123.123.12.12:8765, the router will see that, use it’s set port forwarding rules that YOU set up to say ‘oh, hey, I need to send that signal to...’ and then send that signal to 192.168.12.12:5900 (because of your rule), where running VNC on your turned-on laptop will see it and allow the connection.

To set up a port forward, you need to know (or set up) whatever port your required software uses...I use VNC remote desktop a lot and, as mentioned above, it often ‘listens’ on port 5900. Then you log into your router’s web-based setup page and add a port forward rule where you pick an external port (make sure if’s not one that is in common use already with a certain program (ports 5900-6000 would be OK for that I think, for example) an tell is to send to an internal port at the IP of whatever device you want to recieve the signal. So, for me, if I have 5 computers all set for VNC access and VNC on all of them listens on port 5900, I could set the router so that if a signal comes in at 123.123.12.12:5976...send that to my desktop PC’s IP address....if it comes in at 123.123.12.12:5977...send that to my Media Center PC’s IP address...if it comes in at 123.123.12.12:5978, send that to my laptop’s IP address, and so on.

That was a poorly written explanation, but I hope it makes some sense, lol.

Thank you for taking the time to explain that. I have some specific questions in response.

First, my setup is a straight-up cable modem, which I purchased on my own. No WiFi router there, just a modem. Behind that, I have a TP-Link AC4000 router with MIMO and a bunch of other alphabet soup that I am clueless about. If my Comcast-assigned external IP address is 75.75.51.51 and, as in your example, a request comes for 75.75.51.51:2222, would that request sail through the modem and then get routed by the TP-Link router?

In this example from your reply, is the 5900 on the laptop a number that you chose? So would you set something on the laptop that assigns that number to itself and then set a rule in the router that listens for the :8765 external request and then route it to the :5900 internal port and IP address?

I have a decent understanding of IP addresses internally, as I have many times set static IP addresses on printers, and even fiddled a little bit with subnet masks. (I’ve also done a fair amount of work with binary mathematics, FWIW. You can do long division, multiplication, fractions, et cetera in binary.)

Anyhow, the port forwarding and accessing machines from outside my home network is something I’ve always been curious about, but afraid to mess with it for fear of creating a security weakness.

No problem!

OK, You have a separate modem and router, that’s what my setup is like at home, so your router is where you’ll do the configuring.

“If my Comcast-assigned external IP address is 75.75.51.51 and, as in your example, a request comes for 75.75.51.51:2222, would that request sail through the modem and then get routed by the TP-Link router?”

To note, to start, keep in mind that external IPs ARE DHCP-assigned (usually), meaning they can change over time, so there could be a day you try to connect remotely and it won’t work because the external IP you are using isn’t actually the one your router at home has anymore, if that make sense. To answer your question, y es, as long as the modem itself doesn’t have some sort of firewall or setting active that would block the incoming signal from getting to the router.

“In this example from your reply, is the 5900 on the laptop a number that you chose?”

In my case, 5900 is the default port the VNC Remote Desktop software uses in it’s software. I could change that software setting to anything else, but I don’t need to as I can use the router to direct the signal to different machines behind it via IP address, so I have no need to change the VNC port in the software. So, on my laptop, desktop, Media Center PC, etc, the default port on the VNC software on all of them could be left at 5900 as they still all have different internal IP addresses.

So would you set something on the laptop that assigns that number to itself and then set a rule in the router that listens for the :8765 external request and then route it to the :5900 internal port and IP address?

Kindof, pretty much . I would set a Port Forwarding rule in the router where I pick any INCOMING port number. To explain, again, using VNC as an example:

Say my external IP was 123.321.12.12 and I own 3 computers, a laptop, desktop and Media Center desktop. I want to be able to remote into any of them using VNC, so I install the VNC software on all three and start it on all three, so they are all listening within the home network on port 5900, as that is VNC’s default port - I don’t need to change that port in the VNC software because I can use the router to route incoming connections using a Port Forward to any internal IP address (in this case). The laptop has an internal IP of 192.168.1.101, the desktop has an internal IP of 192.168.1.102 and the Media Center PC has an internal IP of 192.168.1.103. I can pick the external port I want to use to connect. So, say I decided I wanted 5955 to be the external port for my laptop, 5956 to be the external port for my desktop and 5957 to be the external port for my Media Center PC.

I would log into the router’s web interface and create a rule, in this example, for the laptop. The rule would say that if somebody, using VNC software somewhere out on the internet, tries to connect to external IP 123.321.12.12:5955, the router would sense this incoming connection, see port number 5955 and direct it to IP address 192.168.1.101:5900 (the laptop’s IP and VNC’s default port number for connections) on the internal network. If I wanted to connect to the desktop, I would set a rule on my router and then from somewhere other than my house, could use the VNC software to connect to 123.321.12.12:5956, which the router would see because of my set Port Forward rule and route that to 192.168.1.102, and so on.

That all being said, some remote access is not done in this way at all, and I have dealt with other remote security camera software which is more cloud-based...not in the sense that your recordings are stored in the cloud, but in the sense you create an account with the company/software and if you log into your account on their website online, it shows you a list of hardware you own also logged into that account where you can chose a piece of hardware (a camera DVR) and then access it and it’s data remotely that way.

Yeah, that camera looks like  a pretty good bang for the buck and since it is a PTZ it is a decent value. There is always a risk that your NVR software won’t support the PTZ function on that camera, but it is likely standard enough to work.

Yes, usually you can get a full size external for less than a same sized bare drive. Takes about 5 minutes to crack into them and viola bare drive.

They’re usually 5400 rpm drives but that’s fast enough for media storage and streaming.

I’ve shucked a few, but never bought one just to shuck.

Manageable APC have a USB and/or network connexion that allows notifications on the computer that there is a power event then you can set the computer to do something like stopping F@H if there is a power loss and do a graceful stop when the battery lifetime or percentage is under a certain threshold.

I was wondering about just that thing, whether there was a way to exit F@h in the event of a power failure. I assumed there would be, but I was going to ask you about it.

What do you think of this camera?

https://smile.amazon.com/dp/B082MPKJHP/ref=cm_sw_em_r_mt_dp_jRTjFb1BCH691

With the camera, cold I use either PoE or the 12V power jack?

Is there a bullet camera you’d recommend? I really don’t need turrets, I don’t think. Didn’t we establish that 1080p was adequate?

This one is very close to me. The size of the thing won’t be an issue.

The first is very well priced, especially with the additional battery pack, it’s a modern product that would be already enough for a single computer/server even without the battery pack and the display seems to be able to display every infos you might need which is a bonus.

I got a HP T1500 Gen3 (1400VA ,so almost the same) that is about 10 years old (and still with it’s original battery) and with my main computer and its 34" (21/9) screen and my home server running on it, i have an estimated time on the batteries between 35 and 40 minutes while not doing much (posting here for example, i am around 180w @240V), i recall that even trying to do CPU (Ryzen 7 1700x slightly overclocked and GPU (1080 GTX slightly overclocked) burn test (100% usage) it was still around the 15 minutes mark.

The second model is a rackable unit that is sensibly bigger and heavier, it will also most probably not be silent (the first one seems to have it’s fan running only when on battery) and is not meant to be put directly on the floor (would not really be a problem but quite annoying to move it or access the plugs) as it’s meant to be racked on a datacenter or at least a server-room.

Being an older model, there might not be software support anymore (or no user-friendly software as it’s not meant for home-use) and the batteries could be in bad shape (it also might not be the case).

—

Summary : I would rather take the first unit if you don’t have a server-room with a rack cabinet as the capacity with the additional battery pack is the same as the biggest model of the rackable units.

But if you are on a budget or don’t care much about anything else than the capacity then the 2nd option is definitely nicely priced (if the batteries are in a good shape).

Thank you for that analysis. You confirmed a number of things that I already suspected. The first one is in Soquel, which is about 70 miles from here, but I’d drive down there to get it. I haven’t heard back from the seller yet. The noise issue on the rack-mounted job is not anything I’d considered. I’ve emailed him as well and asked him about managing the thing software wise and I’m waiting to see if he is willing to be helpful or not.

That is decent looking high resolution camera, and I think 1080 would be fine if you’re just using it for class video stuff. The viewing angle on that one is a little tight at 78 degrees but depending on what you want it may do.

Are you going to be hard mounting the camera on a wall or repositioning it often? The advantage of a turret is you can set it on something flat instead of mounting it and move it around where a bullet won’t stand up on it’s own and needs to be hard mounted to a wall, ceiling or desk.

I think I have a 4mp dahua turret with a Mic in it that I’m not using if you want it. I can ship it to you with a POE injector (if I can find one). I bought it for a project and didn’t end up using it.

I’d love it. Can I pay the postage ? I don’t need an injector since I ordered a couple of four-port PoE switches.

I’m going to use a turret camera as a “classroom” view in my teaching studio. But I also want to get home security up and running. So it’s time to get up to speed on IP camera basics. I’d mount a couple of stationary cameras on the front of the house, porch and driveway. I thought stationary cameras might be a bit cheaper.

This T7400 “server,” the CPU slot for folding is not activated, only the GPU slot.

Yeah, email me your address and I’ll get it in the mail in the next few days.  I'll let you know what postage costs then.

You might eventually overwhelm that CPU depending on how many other things you're doing with it since it's an older one, but it should do to get you started.

Do you think the CPU(s) could be upgraded on that?

What’s the model number of the CPU in there?  It's several Xeon generations old but that also usually means they're cheap if we can either get a second CPU or a bigger one plus some more RAM too.

I went and bought that APC 1500/spare battery from that guy today. There’s no USB port on the back, only network ports. There’s a pair labeled in/out and a separate port labeled DATA. Do I route the network cable to my machine through the UPS to the switch in order for my computer to see it?

You should check the documentation as I don’t know this specific model but the data port could be a RJ45 port that gives access to the management interface through network or it also could be a port that should be used with a specific cable that ends up as a serial or USB cable on the other side.

I had not considered the possibility of a proprietary cable, but that makes sense.
