Home All-In-One Based on Intel NUC

Recently, my dream came true for the best - in my opinion, a device for a home processor. Studying the experience of others, I realized that the right choice of hardware is the key to success. So, what I wanted to set up for simultaneous work on the NUC:

- NVR for 3-4 HD IP-cameras;
- "controller" for a smart home;
- KODI (XMBC) media player for IP-television;
- Well, of course, a torrent rocking chair.

The harvester should operate 24/7/356. I will sign each point, so that my motives would be clear.

1. Since 2008, I have been living in a private house that I built myself. When choosing what to look after the house - the choice fell on IP-cameras, and of course NVR to it. I have Ubiquiti AirVision IP cameras, a few years ago I bought a set of three. One stands at the entrance to the courtyard, the second for 400 meters via Wi-Fi PtP link at the entrance to the neighborhood. She also watches over the trash, recently I connected it to the popular cloud-based video surveillance service and posted a link on the site of the microdistrict, now conscious people can decide whether to capture the trash or suffer in the morning before leaving. Something happened with the third camera with a color shift on the sensor and it is still in stock. In general, NVR needs to be compatible with Windows or Linux (Debian, Ubuntu). It is for these OSs that Ubiquiti UniFi distributions (formerly Airvision NVR) are distributed. for a while I ran software on a gaming PC, but its power consumption cannot be called economical. Even Intel Atom-based self-assemblies were equipped with a power supply of about 150 watts. IMHO, for such things you need a piece of iron with a consumption of less than 100 watts.

2. Now I am reading with interest the publications of the respected Sergey_Tokarev . My choice also fell on mFI, though everything was bought only in separate samples and is waiting in a box (recently a daughter was born and not yet toys, even adults). Of course, I would like to automate some things in the house with convenient access from the outside. Ubiquiti's software is good for this.

3. There really is a whim of relatives, my wife does not like the picture on new televisions with built-in Smart TVs, she likes the old LG, which does not have this. Recently (about two years ago) a cable provider has finally appeared in our neighborhood, pulling optics to each subscriber. Even the non-sour price for connecting (15 kroons) and the rather large subscriber (1 kroons) by the standards of multi-apartment buildings did not scare me away. Were forgotten like a terrible dream RTK-CDMA, Enfort, Wi-Fi operator with a link of 4 km. Even Yota, to which I connected immediately when they entered, was put in a drawer in case of a reserve (my uncle took it to the country for the summer). The operator gives a triple-play service, I did not take the phone, but IP-TV with more than 200 channels, as a free add-on to the channel, is just that.

4. We sometimes like to watch old TV shows at leisure, and where to get them if not on trackers? In order not to think about how much Gb there is left, and NVR with weekly records can not be replaced.

From experience, I’ll say that I’ve tried several candidates for the role of a harvester - different PCs based on mini-ITX, Cubox i4 (based on arm). Cubox on energy consumption, of course, gave odds to everyone. BUT, Ubiquiti does not have a free NVR for ARM, and even in the long run they rejected them in Feature request, saying that ARM has insufficient performance. Therefore, he successfully coped with the role of the XMBC media player until it burned down last year during a summer thunderstorm. Even then, on the pages of this respected resource, I read in a review about Intel NUC and outlined it as the next candidate. And cheers, at the end of May D34010WYK was purchased, to it msata 128 Gb SSD, 8 Gb LV DDR3 SO-DIMM, Intel Centrino Wireless-N 2230. I installed Linux Ubuntu 15 Vivid and started testing. Everything flies, copes with loads.

But then I realized that I flew a little. I was counting on ssd configuration under the system partition and 2.5 dummy sata hard drive for NVR data and torrents. There are sata + power connectors on the board. We decided to make a spacer between the NUC case and a removable cover, and fix an additional drive there. But they didn’t manage to cut it: last year’s trouble came again, the storm passed and after it the NUC’s ethernet port was lost. In dmesg, the device cannot start with error 2. Hands almost dropped, although it works fine on Wi-Fi as a TV box. But the band for the functions of NVR and torrent is clearly not enough.

I decided to take it apart and look at the other side of the board. And here disappointment awaited me. As a person associated with the repair of devices, the board of a well-known manufacturer, VERY surprised, was not washed from the flux after soldering. For doubters, I suggest a look

since specs with intel.com she is responsible for ethernet.

Of course, one could attribute it with “honest” eyes to a guarantee, but this is “low class, unclean work” (c) O.I. Bender. I consider the probability of element-wise repair of this device in nearby SCs to be low. Therefore, I outlined three options for the development of events:
a) it will be possible to find mikruhu, replace it and it will work. The most difficult but also preferred option will give skill upgrades.
b) I will not find mikruhu, or will not work (other elements are faulty). Replacing the Wi-Fi adapter with a dual-band, with support for AC (the router is also dual-band). Try to see if the 5GHz bandwidth and router performance are enough. The option is average, it is likely that there will not be enough strip, or the router will not cope.
c) leave the NUC as an expensive TV-BOX. Bad option, akin to failure.

In any case, we will move on. By the way, I can give a link to the developed spacer for NUC, maybe someone will come in handy.
