i know that IP will take over in the near future but in my line of work the quality and price has still a bit of work to be done to get it on par with current analog devices
1 brand you guys might want to have a look at that cought my eye for quality and features was ACTi. these camera's can have 2 diffrent streams at different settings running from them at the same time, so you could have 1 stream runing @ 4CIF 30 frames to your recording equipment and another stream running @ 640x480 for remote viewing to save bandwidth over your internet connection. These units also support 2 way audio witch could be good for a front door or gate.
I'm not a hard core analog guy its just i look for the best solutions for my clients with there pockets in mind
