Here in the U. Other providers in the U. Given that GSM is more widely used across the world, and cell phone network intercoms have been popular in other countries such as Europe, at this point only GSM intercoms are available. Manufacturers want to develop equipment that can be used by the widest variety of markets so they can quickly recover development cost and make a larger profit. These intercoms have not been available in the U. Telecom industry trade association US Telecom says that traditional wire-line service dropped from 95 percent of U.

According to the Centers for Disease Control, as of the second half ofone in three U. To use a one of these intercom you simply sign up for a service that uses GSM and you take what's called a SIM subscriber identification module card that you get when you sign up, and you place it in a slot inside the intercom control module.

When someone presses the button on the intercom, it dials out on the cell phone network and places a call to any landline or mobile telephone, no matter where that phone is. As long as there is cell phone service at the location you want to place the intercom, then you can place it there. You can even power the unit via solar power. Most of these intercoms can dial multiple telephone numbers until someone answers so visitors at a door or gate are more likely to reach someone.

The person reached can press a key on their telephone to activate a switch in the intercom that can be used to open a door or gate remotely. Some GSM intercom enable you to use text messaging to send a message to the intercom to do the same thing. Another nice feature is their ability to pre-program telephone numbers into the system so certain visitors can just call the intercom, and based on their caller line ID, the door or gate will open.

With these intercoms you can:. What is a GSM Intercom? With these intercoms you can: Let family members, who forgot their keys, enter the house. Let delivery people in with instructions on where to leave packages. Not have to run over to an intercom to answer the door. Use text message to latch a gate open for parties. Have convenience and peace of mind from having all of the above.This is a really interesting solution to a relatively common problem of implementing a whole house intercom system.

You can really learn a lot about electronics and micro controllers by reading about this project. Check out the link for the circuit diagram, code, and very detailed description of the entire build process. The intercom temporarily disconnects premises telephones from the Telco line, and rings them with a distinctive cadence.

After a suitable ringing period, pick up your phone and wait for someone to answer. When you take your phone off hook, or someone else on premises goes off hook, the intercom stops ringing and supplies premises phones with talk current.

All off-hook parties can converse. When all premises phones go back on hook, the intercom re-connects them to the Telco line. More about the Arduino based telephone Intercom [ Arduino forums ]. In the Maker Shed: Make: Arduino.

GSM Intercom systems are the best solution to long-range wireless intercoms. Unlike a typical wireless intercom which use much weaker radio-frequency signals, these GSM intercoms use the mobile network via a SIM card, just like your mobile phone, to allow for an unlimited wireless range!

What's more, because these door entry systems are not restricted by the available radio frequencies that standard wireless intercoms use, it means we are able to offer the incredible door entry system for up to flats!

It's actually very simple! The intercom station is set up to use a SIM card to make the calls when a button is pressed at the main gate or perhaps the communal door on a block of flats. This will call the pre-defined telephone number s of the occupant - this can be their landline number or mobile number - or both!

That's right, you can also set these up to call one number - let's say the land-line number in this case - and if there's no answer after a predetermined amount of time, then it will attempt to call their mobile number instead. Pretty nifty right?

Another incredible feature these systems offer, is that you can phone the intercom to unlock the door providing keyless entry! This works by means of a white-list feature, where if you know the phone number of the SIM card in the GSM Intercom, and you were to call the door intercom from your mobile phone as you approach the property, if the intercom recognises your telephone number from its list of authorised numbers, the intercom will trigger and unlock the door for you!

It is important to choose the right network carrier. If you know the network that gets the best coverage in your area then go with them! Whether that be EE formerly OrangeO2, Vodaphone, Three, or any other preferred network - as long as you know it has good coverage.

How Does a Master Key Work?I built this system about a year ago, and I get so many people asking me how it was done I figured it would be a good post to help reboot my blog….

Both during the week and on weekends I entertain quite a few guests. Access to the property is through a motorised gate. Often guests ringing the doorbell will be doing so in vain, as the ringing can only be heard from inside the main house.

Usually I get a message or a missed-call on my mobile informing me that someone is outside the gate and that no one is answering the doorbell! One solution to this problem is to add extra intercom extensions to the Playroom and the braai area. I figured why not let my guests let themselves in, using their mobile phones! And so the idea of GSM-enabled gate access control was born. I had recently been exposed to the world of Arduino by my friend and collaborator Tegan Bristow and thought this would be a great problem to solve using the Arduino platform, learning as I went along.

And some of you seasoned electronics engineers will think WHAT!

Which is true. I could sit and design an elegant solution featuring only the necessary electronic components, using power-saving design techniques and choosing just the right microcontroller for the job based on number of used IO pins and peripheral features.

Perhaps one day I will. Coming from a background working with PICs and AVRs from scratch, it was actually quite nice to spend more time tweaking a mostly working design, as opposed to tweaking a design to be mostly working.

It has its own bathroom, some comfy couches and used to feature cupboards full of toys and games and even an old piano. The next problem would be how to open the gate remotely. But as I spend most of my time in the Playroom I wanted to be notified visually or audibly of guests arriving, and dreaded the thought of running cable from inside the house to the Playroom.

Then one day I stumbled across an unused remote control for the gate — its plastic buttons had broken off and it was just lying in the kitchen drawer. I could tap into the button on this remote control and have my system sit in the Playroom or anywhere in range of the gate control receiver!

After figuring out the required hardware I moved on to thinking about how I would control access. My first working solution used SMS messages, where the gate was opened on reception of a text featuring a four letter password. The cellular shield communicates with the microcontroller using UART serial comms, sending cryptic text strings to show what is happening in the GSM cellular receiver.

It was easy enough to look through the text string to find the relevant password and act accordingly. It worked! But many of my friends complained that by sending an SMS they were in effect spending money to visit my house. Most of them jokingly complained, but it still got me thinking: How could I reduce the expense of opening my gate? First thoughts were to use the GPRS capabilities of the Cellular Shield to access a web server or app accessible from mobile phones.

WOW that seemed over-complicated, and would take up way too much of my time, and would probably be quite tedious for the visitors to accomplish as opposed to sending a text. Then I thought back to how I usually knew someone was at the gate — a missed-call on my mobile!

So I then redesigned everything to work as follows:. You will notice that I have included a PC to manage the whitelist. It just seemed easier to do in Python. I am now in the process of working out a PC-less version of the whole system, using an SD card interfaced to the Arduino for whitelist storage.SIMA can search these two bands automatically.
