Aren't Red Light Cameras just an attempt by the Village to raise additional revenue?

No, but as with any ticket, those issued a citation are required to pay a fine. These funds go back into the operating expenses of the service and provide additional revenue for the village. The objective of photo enforcement is to deter violators, not to catch them. Signs and publicity campaigns warn drivers that photo enforcement is in use. Red light cameras are in plain view, not hidden. Revenue is generated from fines paid by drivers who continue to run red lights, but this is a fundamental component of all traffic enforcement programs.
