Webcam vs. composite Camera
Anyone can vouch for the quality between Webcam vs. composite feed camera?
I'm in the initial planning stage of a Linux-PC-based PVR and need to roll out additional cameras.
The cost effectiveness of extended a USB webcam using a pair of USB-serial-Ethernet convertors/adaptors doesn't seem worth the while (not to mention the possible subpar quality). These convertors/adaptors enable extending the distance to 300m for Ethernet CAT-5e cabling. The plus side is that USB is relatively easy to add to most existing PC platform.
The composite cameras seems to have higher resolutions but requires a composite adapter PCI/USB card. Those cards are about the same price as a pair of those USB-serial-Ethernet convertor/adaptor.
I haven't seen the "convergence" or sweet spots yet, perhaps someone else has.
