Re: Reliability of Raspberr Pi for a Home Security/Alarm sys

You would monitor the mains before it goes to your UPS. ;) What I was trying to say is that the UPS has to know that the power is cut, how else could it know to take over? So you don't need to monitor it yourself if you can just get that signal from the UPS itself. But if your power is out, likely ...

Re: Reliability of Raspberr Pi for a Home Security/Alarm sys

I was thinking a simple relay on the mains. If the mains drops then the relay goes open and that's the trigger to send off a notice. Surely when they kill the power, the pinging stops which alerts you to trouble. If you are using a UPS, aren't you getting notification that you are on battery power?...

Re: Reliability of Raspberr Pi for a Home Security/Alarm sys

Well, I could of course program in a Mains detection bit, that would send off an SMS if it drops (I'd probably like that any how). Just regularly ping your buddy's computer that is located somewhere else. If that stops working, then you know something is wrong and can have some sort of alert get se...

Re: Reliability of Raspberr Pi for a Home Security/Alarm sys

4 doors to the outside, key panel and RFID... But what level of protection are you aiming for ... What happens if someone kills the power to the building, or walks up to an external sensor and puts a 90kV pulse into it ? If it's just to stop opportunist burglars then anything is probably better tha...

Re: Reliability of Raspberr Pi for a Home Security/Alarm sys

I'm toying with the idea of making my own security system and I know Raspberry Pi offers a LOT of cool ways to do some cool stuff. First thing you need to do is define what it is intended to prevent, protect or achieve. Then you need to determine how resilient and resistant it needs to be to delive...

Re: Reliability of Raspberr Pi for a Home Security/Alarm sys

Whew! Didn't meant to light fires in here. The reason for my questions about stability is that a Pi is running a fairly complex OS. Yes, a similar OS to mine and many servers out there that run for YEARS without fail. ABSOLUTELY. BUT... it is still a LOT of "moving" parts. An Arduino is a fairly bas...

Re: Reliability of Raspberr Pi for a Home Security/Alarm sys

I'm not looking to get any discounts on my insurance. I'd use the Pi for self monitoring purposes have it call me with a SIP VOIP account, send me an SMS alert. I'm assuming the Arduino is more stable for monitoring reed switches and sounding sirens if one is triggered and they don't put in the code...

Reliability of Raspberr Pi for a Home Security/Alarm system?

I'm toying with the idea of making my own security system and I know Raspberry Pi offers a LOT of cool ways to do some cool stuff. I also know there is already a project that is well established for this (PrivateEyePi?). My question is how reliable is this vs an arduino for the bulk of triggers and ...

VOIP call with prerecorded message possible?

I have a project where I'd like for my system to call me with a prerecorded message when certain things happen. I already have a voip.ms account which is compatible with most SIP compatible systems (soft phones included). Is it practical to assume this can fairly easily be done on a Raspberry Pi sys...

Re: C-Media USB Mic volume issue

I'm very familiar with audio (normalizing and all that jazz)... I was a sound engineer in a previous life. Problem is that the source is almost non-existent. If I'd normalize it would just make it extremely noisy. Amplifying it before would be best, but it's not practical for my purpose. This soundc...

C-Media USB Mic volume issue

I've got a C-Media C119 usb card that I'm trying to use to record audio with.

I can record the wav but it's EXTREMELY low volume.

I've run alsamixer and tried to tweak the volume but it doesn't really seem to be working.

Anyone got any ideas?

I'm very interested in this project.

Would like to monitor/log weight of hives on the cheap.
