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 and the Navy are the only services which have active duty enlistment options of less than four years, which are not part of the National Call to Service program. The Army offers enlistment contracts of two years, three years, four years, five years, and six years. Only a few Army jobs are available for two and three year enlistees (mainly those jobs that don't require much training time, and that the Army is having a hard time getting enough recruits).
