Re: Maximum USB



I use gotcha for 2 years now and it locks only if you have a bad camera driver.
Now I have a Philips ToU Cam Pro connected to Gotcha and it never locks. I think this is one of the best webcams available on the market (<1lux, CCD, full automatic or manual adjustments).
Gotcha! works great on Windows 9x/2000/XP (tested by me). The main issue can be the camera driver.
Let's say, the Philips ToU Cam XS is one of the worst possible solution for Gotcha. It hangs a lot (especialy in XP) and it is allmost unusable at low light.

P.S. I'll check the supervision site. It is the first time I hear about this product.

Dan, how is Gotcha performing? I tried it a while back and it locked the
PC (W2K) every few days.

Im now using supervisioncam, www.supervisioncam.de. I have found this
software to be far more reliable than Gotcha, and its cheaper to.

I think that an analog B/W camera is more expensive than a color USB
one, with mic included.
More than that, the driver of the USB cam can do all the adjustments
automatically (like sensibility, number of frames per second, contrast,
etc.). Especially for suveillance, where you don't need 25 frames/s,
decreasing the frame rate to 5 or 3 frames/s can give you much better
quality al low light (s/n ratio).

Other dissadvantages of analog cams in surveillance:
- separate power supply (cheaper ones can get a lot of power)
- cheaper capture cards need a lot o processing power to capture the
video


A very good surveillance application, cheaper for single cam but much
more expensive in multicam version is Gotcha! (see
http://www.gotchanow.com/ ).
Unfortunately, the multicam version doesn't work with standard USB cams.

One of my webcams is connected to the Gotcha application and accessible
on the Media Encoder too, as a Screen Capture (a small trick..:) ).

Any other opinions?

Dan
