Yes, the extenders don't carry power, so you need to use a local power supply at the camera. I don't think there's a "supported" way to run power over that distance, but I don't know why it couldn't be done.
This is an ongoing challenge because our cameras are never co-located with the codec. I'm wondering if it wouldn't be possible to use Power Over Ethernet for that purpose. I can't find published specs for the power consumption of a PrecisionHD, but the label on one we just checked says it requires 12volts and 2amps. That would be just under the maximum power available under POE specs (25.5 watts).
In a white paper dated this year Cisco claims to be able to deliver 60 watts over POE. On the surface it would seem the only thing missing is an adapter to connect the camera to a POE power source over Cat5 cable. The cost of a POE supply and an adapter like that might be worth it when compared to the cost of paying an electrician to install a dedicated power outlet, and the hassle of mounting an external power supply at the camera location. Running the Cat5e cable would be less trouble than running the camera extender cables, which you'll have to do regardless.
