Is this acceptable blue iris machine and can I add 3.5 drive.

[jayleoness]

Wanted to confirm that this would be an acceptable blue iris machine for me. I have done the calculator on here and believe this to be more then ample but just wanted to make sure and get any feedback. I have never bought a used pc before so not sure if there are keywords to look for either like off lease or whatever. I was originally looking at Dell Optiplex but after reading a bunch of @fenderman I saw he recommended these. Also wanted to confirm that I can add the 3.5 western didgital purple drive to this. I like that this one already has windows pro and an ssd installed so I would only need to add the storage 3.5 drive.

My setup is 4 x 4mp Dahua 5442 starlight cams at 30 FPS.

According to the specs
HP EliteDesk 800 G2 - SFF | Product Details | shi.com

there are two free 3.5 inch drive slots.

The processor should support with no problem your MP/Sec load. I would recommend dropping to 15 FPS, You are not shooting a Hollywood movie, you are collecting evidence of criminal activity.

So if FPS is at 15, is that for recordings? Or just for live streaming? If so, is it possible to increase the FPS when motion is detected?

I guess if my pc can handle it I don’t see why you wouldn’t want to run at the max fps in either case.

When you change the frame rate, you change it for the stream sent from the camera to Blue Iris. So, it affects both live viewing and recording. It is not possible to increase the frame rate when motion is detected.

The main benefits of lower frame rate are:
* Lower CPU usage. By running with a lower amount of CPU usage, your PC saves energy ($$) and produces less heat. It also is less likely that your CPU will become overloaded in periods of peak activity, like when you are connected with Teamviewer, or you are reviewing clips while Windows is doing an update.
* Depending on other encoding parameters, a lower frame rate means you will have a lower bit rate (smaller file sizes), higher quality, or both.
* You can play recordings at an accelerated rate in Blue Iris (like 2x, 4x, 8x speed, etc), and playback will be able to reach higher speeds smoothly if your source recording is a lower frame rate.

So, by all means, run the cams at 30 FPS if you want to. 15 FPS is just the recommendation because it is considered good enough for most purposes, and it is a whole lot more efficient and generally performs well because Blue Iris has twice as much time to work with each frame (compared to 30 FPS).

Got ya makes sense. I’ll go 15 then.

Question about these dell optiplexs. I’m asking the ebay sellers if it’s possible to add a 3.5 hdd in addition to the ssd and so far they have all told me “no” for the optiplex 7040 and 3040. Is that accurate? Seems the recommendation is always to have the ssd and a hdd for the recordings

This is the 800-G1 so I assume it’s similar to the G2 (no idea what the difference is). The tray flips up and has two 3.5 bays and a 2.5 bay. On mine there are only three SATA connectors so my BI machine has the DVD drive disconnected so the cable can go to a HDD. What I like about these business machines is the tool-less drive removal. Just flip a lever and they slide out.

Ya that is nice. Although I think these optiplexs are actually a French inches smaller in length and width which is why I’m leaning towards them now.

most of the member use the WD purple drives. The purple drives are designed for security systems.

Isn’t the recommendation for a ssd for os and blue iris. Then the purple drive for recordings. I’m just wondering if it’s possivle to fit both inside these optiplexs

No idea about the Dells but I have a HP 600 G2 with the same i5 CPU, no idea of the difference in other terms and I’ve got an SSD and 2 standard size hard drives installed in mine. As pointed out above I’ve had to disconnect the DVD drive but in this day and age that’s no great loss.
