Telephone Entry Systems are the gateway between you and your guests. With a telephone entry access control system, you’ll be able to communicate with every visitor remotely and allow or disallow access at the touch of a button. With one button, visitors will be able to call you directly to your office, home or cell phone. Crime Intervention Alarm offers custom solutions that fit every need and budget.
