Bluetooth phone for surveillance

I have a Sonyericsson z1010 and just bought a bluetooth trasmitter on my pc.
I was wondered about the capabilities of the bloethooth system! (like using
the pc for calling and hearing the phone call on the pc hearphones).
So, stimulated from this tecnology I asked myself if it is possible (maybe
some I need some software for this) to use a Blouetooth phone and my pc to
use the phone to control video and audio of another room... I mean: I leave
my mobile into another room and I can see from the pc trough the mobile
camera and hear from the mobile microphone.
The tecnology it's surely capable to do this but then, is it really
possible? None knows if some software can do this? (it could be usefull for
surveillance for example).
Thanks to anyone who could answer.

That would take a special Bluetooth profile that isn't supported.

Not to mention that a bluetooth connection doesn't really have enough
bandwidth to transmit any kind of live video. Of course it could be
compressed and converted but that would be more hardware required in the
phone and it would be poor quality.

On the lesser SE phones based on the same platform as the Z1010, you can
remote control the camera (not sound, not video, AFAIK) from your PC via
Bluetooth. It has been demonstrated on the K700i.

I don't really think so!

Bluetooth is capable of 721 Kbps, which is quite adequate for decent video,
particularly with a low frame rate, which wouldn't be a problem for video
surveillance.

I think our interpretation of "decent" is different. I think that the
streamed video I get over my 1Mb/s is still pretty poor quality. Having
said that, the video as recorded by the k700i is pretty poor so it would
quite easily be transmittable over 721Kbps, as you have already stated.

Perhaps that's due to suboptimal encoding. The latest codecs (WM9, Real,
MPEG4/Quicktime) are capable of decent video even at 300 Kbps (about all that
Bluetooth can handle), given (say) 320x240 frame size (VHS quality) at 10-15
frames per second (a bit jerky, but still decent). At 600-900 Kbps you can
get quality that's quite good.

Agreed.
