In the video Michael shows us how the TTS system was developed for the 4G GSM intercoms. This system tells installers what is wrong with the setup and how they should go about rectifying it.

We had a report of the dial-to-open system on a 4G GSM intercom not working periodically using a Vodafone Ireland SIM. Everything else about the unit was working perfectly so we had to investigate. TLDR; it was working fine... perhaps a wiring issue We set about writing some firmware that could log the relevant information and allow us to see what happens within the software from our office in Liverpool. The actual GSM intercom was in another country but that doesn't matter as we can see the inner workings from anywhere. In fact the server we use for it to connect...

The 4G LTE Cat-M1 band and the '5G' NB-IoT band being rolled out with mobile phone 5G bands are the bands the networks intend you to be using for machine-to-machine (M2M) products. They offer the basic level of service required for these products and in return the networks charge very little for using them. NB-IoT is not accessible using mobile phone SIM cards; you need SIM a dedicated IoT to access them. These SIMs won't be connected to the Public Switched Telephone Networks (PSTN) so dial-to-open with your cheap PAYG SIM is not an option on these modern networks. You...

If you have a traditional alarm dialler/communicator that sends SMS messages and makes calls from the actual unit using a mobile phone SIM, then you won't know if it stops working until it's too late. This is one of the reasons we created the cloud dialler... If it's our cloud server sending the messages and making the calls we tell you when your dialler goes offline. You fit an alarm dialler to alert you to critical events that are happening when you're not there. If your dialler is responsible for telling you what is happening, how will you know when this...
