Which is better - Intercom, Keypad or Telephone Entry System?
The Telephone Entry System (TES) is the most flexible system. A good TES system will give you the flexibility to use multiple phones with multiple access codes which can even be allocated to different time zones. So for instance if you have regular deliveries you can allow access to your electric gates within a certain time period for that specific person. With this system it is not necessary to purchase additional remotes or continuously change the access code.
