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.
The Army enlistment contract options available to you will also depend on the kind of training you receive. Some Army programs and training schools might require you to commit to a minimum four- or six-year active duty service obligation, while others allow two or three years.
