There have been a couple of recent burglaries in the neighbouring offices<br>
|
||
and I'm interested in putting some cheap b&w cameras in my office, mostly<br>
|
||
as a deterrent but also for storing photo evidence to help out the police<br>
|
||
if (god forbid) my offices are burgled as well.<br>
|
||
<p>
|
||
It looks reasonably easy to use SANE to connect up one camera and use the<br>
|
||
sanecgi software to store continuously running images. I'd then upload my<br>
|
||
images to an offsite server (in case the servers stolen). So 1st question<br>
|
||
is: what cameras do people recommend for this sort of application?<br>
|
||
<p>
|
||
Cheap is preferred, but keeping CPU costs low is also important. I have a<br>
|
||
small battery of servers, but I'd like to keep all this scanning software<br>
|
||
on a single machine, probably a PII-333 running Linux, which will also be<br>
|
||
doing a number of other things. Another issue is cable length (need 10m).<br>
|
||
<p>
|
||
I'd also like to use multiple cameras, possibly 4 of them. Does this rule<br>
|
||
out parallel port cameras (ie, would the CPU usage sky rocket)? Would the<br>
|
||
scanners require a dedicated server (I have no idea about the bandwidth I<br>
|
||
would need here)? Are there camera "chains" designed for this purpose?<br>
|
||
<p>
|
||
I've looked at the dedicated camera/vcr setups but was unimpressed. It is<br>
|
||
impossible to monitor the cameras from the web, and getting offsite video<br>
|
||
storage costs an arm and a leg, far more (I think) than even buying a new<br>
|
||
dedicated server just for scanning and paying for additional bandwidth.<br>
|
||
<p>
|
||
What else am I missing? I've never had a scanner before, let alone one of<br>
|
||
these new fangled "computer cameras". I'd appreciate any advice.<br>
|
||
