Users / Multi-room audio
« on: August 28, 2012, 11:31:16 pm »
Still in the early stages of designing the home system, one of my thoughts is on piping audio to multiple rooms.  I can have the house pre-wired for speakers, but not sure what the best way to do this is.  I would like sound in 5-6 rooms. 

I saw the option of using network audio players (like the SqueezeBox), but that seems expensive to put in each room. 

Can I just put conventional speakers in each room, and wire them to a bunch of sound cards?  Can LinuxMCE support multiple sound cards in one computer and pipe different music to each?  Or would I need a separate media director for each room (expensive for just audio - most of these rooms will not have video).

Any other options?


Users / Newbie camera question
« on: July 04, 2012, 08:27:38 pm »
I am in the early stages of designing an automation system for my new house, and one of the things I'd like to do is have surveillance cameras.  To that end, I have a few questions:

1) Do I understand correctly that with IP cameras I can have either pan/tilt/zoom, or motion-triggered events, but not both?

2) With motion triggered events, is the system able to exclude non-human motion (cats, etc.)?

3) In terms of IP vs. analog cameras, what are the pluses and minuses of each approach?  I plan on a mix of indoor and outdoor cameras, and see at least 3 different options - IP cameras, analog going to motion capture cards (I am expecting about 10-12 cameras, are there any cards that can support that many inputs?), or analog going to a separate security DVR (designed for multiple cameras), most of which have an IP output, not sure if anyone's used any of these with Linux MCE.

I've heard that IP cameras can be laggy, by as much as 8 seconds or so, any truth to that? 

Also, if I have IP cameras and want to output to a TV, I assume I can do that through a media director, but how's the quality in those cases?  Can I have a media director with an HDMI output to get good quality video on the screen?  In the past, hooking up a computer to a TV (using composite or S-video) has left much to be desired in terms of quality, never tried it on an HD TV with HDMI connections.

Is KNX available in the US?  Everything a quick google search found was in Europe.

What's the wiring for KNX?   Cat-5?  Or something else?

Is there a good guide on setting up a KNX system that anyone knows?

I'm in a very similar boat (less the years of following LinuxMCE - didn't discover it till just recently).  It seems that the protocol of choice varied over time.  Searching the forums, it seems Insteon was hot circa 2008, Z-Wave was the top choice around 2010.  What's king of the hill these days?   If you were doing a clean-page design, which system would you go with? 

I'm mostly looking at lighting, maybe eventually door locks and window shades.  Heating will be handled in a different manner, but AC integration would be nice (room a/c at first, maybe ductless central air later on).

Does it have to be in Ruby?  Can the device driver be written in C++?  I've never programmed in Ruby, but did (admittedly, a long time ago) work quite a but in C++

This is a someday project - we haven't finished redoing the house or putting in the new heating system, etc.  But If I go with home automation, I want to wire for it now, even if this part of the project doesnt go into place for a year or two.

I am planning a new house, and was hoping to install some home automation features.  LinuxMCE seems like a perfect way to go, but one key (for me) feature is missing - I intend to use a Tekmar heating control system (put one in my current house and love it), but I don't see it listed as supported anywhere.  Any chance this is a project someone will be doing in the next few years?  

The full specs for the protocol are on the tekmar website, but I can't seem to post a link to it.  It's on the tekmar control website, search for "482", then click the "Information for Custom Developers" button at the top.

Doesn't look too tough, but not really within my ability to program - I've never done any sort of low-level protocol programming before...
