Cellular Network 100-Unit Apartment Intercom

As long as your gate or door is within range of a cell phone tower, then this intercom's range is infinite. You could be on the other side of the Earth and still talk to visitors for very low cost per visitor if you need to purchase new cell phone service. If you already have AT&T or T-Mobile wireless service, you may be able to just add this intercom to your existing plan with a small monthly fee.

By pressing keys on your telephone keypad you can unlock a door or activate a gate opener so if the delivery person comes while you're out, you can easily let them in. All you have to do is answer a call from the intercom, and press * to open the gate.

This intercom supports up to 100 apartments and can call up to 3 telephone numbers in sequence. You can program up to three telephone numbers per apartment in this unit, whether they are landline telephones or cell phones. When a visitor arrives at the intercom and presses the button, it dials the first number. If the first number does not answer, the intercom dials the second number after the programmed "no answer" time is reached, and it repeats the procedure for the third number. So your visitors should always be able to reach someone and you won't miss important deliveries or visitors.

So for 30 units or fewer visitors can either scroll through to find the person or business they are looking for or they can dial directly if they know the number already.

The keypad can also be used to unlock the door or gate by entering pre-programmed entry codes.

There is also a free downloadable app for Android and iPhone users that management personnel can use. The app can be used to send a text message to latch or unlatch the door or gate release relay. Management can choose to latch or hold the gate open in instances where they want people to come in freely. A PC version that connects via a USB port is also available.

There is no need to run a telephone line or wires to the system, thereby eliminate the expense and mess associated with that task You can pay for many years of service with the money you'll save, plus you'll get benefits you just can't get from other systems.

Cellular Phone Service

In the United States there are two technologies used for cellular telephone service. One is GSM which stands for Global System for Mobile used by AT&T and T-Mobile, as well as almost every other cellular carrier elsewhere in the world. The other technology is CDMA which stands for Code Division Multiple Access, and is used by Sprint and Verizon in the US, as well as a few other companies in Asia and South America. There are other service providers you can choose besides AT&T and T-Mobile that use GSM (they just contract with these GSM carriers to use their service so you are still using either AT&T and T-Mobile service).

To use this intercom you will be required to have a 4G GSM-based telephone service. GSM-based mobile phone service requires use of a Subscriber Identification Module (SIM), which is an integrated circuit that securely stores information needed to identify and authenticate subscribers on mobile telephony devices.

This unit has a 4G SIM card included and instructions on how to activate it. Click this link for more details: Cell Phone Network Plan
