If you are using a dynamic public IP address then you will need to setup a dynamic DNS service to keep track of it. With multiple cameras you will only need to set up one dynamic DNS service with one camera since the public IP address will be the same for each.
Army Enlistment Contracts. The enlistment contract you sign is a legally binding agreement between you and the Army. Failure to live up to the enlistment contract you sign with the Army can expose you to potential criminal or civil penalties.
However, most of these contracts are four to six years of active duty followed by the remaining years in the Reserves or IRR. The Reserves or National Guard duty is a part time soldier but a way to complete your commitment with the military by going to drill one weekend per month, and two weeks per year.
