Intercom Systems are used to communicate with a person at a door with the people inside. Intercom systems can include a door release. After communicating who is at the door, people inside can release or unlock the door by a press of a button and grant entry to the person at the door. Video intercoms are also widely used. This gives you the ability to see who is at the door while speaking with them. They offer pan, tilt, and zoom. These features can be automatic or manual. After you are certain who is at the door, you can unlock the door with a press of a button. This system can be used on multiple doors. The system identifies which door the caller is at, giving you complete control and security of which door to grant access.
Intercoms come in a wide variety of designs. They can be wall mounted stations or desk top units that are no larger than a telephone. They have the video monitor screen built into the station. Most reception desks utilize a desk top unit with or with out video. Depending if they can see the person at the door. If the person is visible to the reception area, video is probably not needed. If the caller is not visible to the person or persons granting access, video might be a good security feature. These units can unlock a wide variety of electronic locks on doors. Magnetic locks, electric strikes, electronic locking hardware and automatic door openers are just a few of the applications that these systems can open.
A wireless hand held release can be added. This will give the opportunity for one person to help customers inside a store and grant access to new customers and not leaving the current customer. These are used widely in Art and Frame Shops, Hair Salons, or wherever access needs to be granted with the only other means to open the door is a person in a fixed location. Wireless hand held releases can also be added to existing systems.
Telephone entry systems might be more appealing for your application. They offer an entry system with the same door release features while speaking with the caller on your telephone. Using your telephone keypad, press the number 9 key and grant access to the caller at the door. Telephone entry systems are unique in that cell phones or land lines can be used to communicate and grant access.
Wireless systems are becoming more popular. They use wireless frequencies to communicate and a separate secure frequency to unlock the door.
