For DIN cables, which come with the observation system or mini camera package, the power source can be close to the monitoring site, but the distance from the power source to the camera should be less than 250ft.

Should the power source located close to the camera? Or, should the power be supplied from the monitoring place?

Many CCD video cameras work with 12VDC and if you can connect correct polarity, you can use a battery pack which produce 12VDC. Some wireless cameras have a battery compartment.
