I searched for, but could not find, the technical info on the Otek Flexi Snake Cam.
However, if your camera is a "UVC" compliant device, as explained in
http://discussions.apple.com/thread.jspa?threadID=2018211
the camera should work with your Snow Leopard Mac without additional drivers.
If the dealer who sold you the camera, the documentation for the camera, or its packaging cannot identify it to be UVC compliant, the manufacturer can confirm whether their product is a UVC device. They may even offer a current production version that
is UVC compliant and, so, could work directly in your OS X without needing to add any software.
Depending on the importance of your requirement to use the camera outside its known-working Windows® environment, if the camera is a USB but non-UVC camera, the macam drivers may be worth testing for your purpose. However, before you install macam software, I suggest that you find and save macam's instructions on how to uninstall the macam drivers, should uninstalling become necessary.
I also suggest you make a complete backup of your startup disk before installing and testing the macam (or any other third-party) drivers. A good backup can make restoring your Mac to a working configuration much faster if new software you are testing causes problems in your Mac's operation.
