  1. Probably complicated but ...

    temp sensor --> A/D converter ---> text inserter

     

    Ding Ding Ding, we have a winner.

     

    If you shop wisely you can probably score that for ~$450, the bonus is you would have a bunch of unmentioned capabiltity as well. In my case I used an Applied Digital Ocelot which is for all intensive purposes a PLC for home use. Add to it's rs485 network a SECU16 and you have 8 A/D inputs or 8 digital inputs plus 8 digital outputs. The same setup rs485 network supports both temp, humidity and ASCII output. You can either use the prepackaged temperature bobcat or use your own probe and the SECU16.

     

    The text inserter would just be whatever you can find thats cheap.


  2. I would go with a PS in a can and put the can somewhere else out of the way. Nothing says the PS and the display need to be close to each other.

     

    Normally I do keep the DVR and PS together but it's not required and what you are atalking about doing is radically cheaper in a can as opposed to a rackmount.

     

     

    Also if like me you have a rack cabinet to put this stuff in, you can buy a 4U rack case and put a canned PS inside it. Now you still have the rackmount and cool factor but costs less far less if you buy a used server and gut it.


  3. Nice to hear that.

     

    So its a live view what eats resources?

     

    Not so much with MJPEG but with MPEG4/H.264 yeah it can become a huge burden to decompress for on screen viewing.

     

    I also have an MPEG4 camera on that system but I have it set to only decode keyframes. The local display looks like maybe 5 fps but the recordings are much closer to 25fps and the CPU load was dropped quite a bit. Granted this is a VGA camera not megapixel.

     

    I'll make you a deal on a little valley if you wanna play with one.
