Churches have used video cameras to record and broadcast their services for years. With new technology paired with lower cost of broadcast equipment, it is easy to do.
When prospective young adults move to your area they research the local church in a new way, by viewing services and other media available online. If your services are available at any time they are more likely to watch, listen, then come to visit. It is well worth the investment as we enter into this new age of technology and church growth.
