About MCDI

MCDI is still doing Alarm Receivers and Monitoring Software like it did back in 1994 when founded in Montreal Canada.

Many will remember the game changer TLR isa receiver and SAMM software. Prior to MCDI’s TLR receivers where big, bulky and expensive. MCDI changed this by thinking outside the box, by in fact removing the box and using PC for power and housing of the Alarm receivers.  We still talk to customers running them after 20 years.

Along the years we made several more receivers on PC boards namely TLR+, Exprecium 1,2,3 and now Exprecium D for PCI or PCI-e slots.

MCDI added it’s first external receiver the SA-TLR+ back in 1997. It was followed by EXSA, Decrypta 1-2 and 3 and now our flagship Decrypta 4. All of them have distinctive designs far from the traditional black boxes.

In 2008 MCDI introduced a line named Extrium. With embedded linux and powerful ARM processor, Extrium receivers offer more features including notifications to Android phones, Alarms over IP  and embedded web servers. Extrium is now ready for new pure IP receivers like DT42.

On the software side the popular SAMM was replaced by WinSAMM at the turn of the century. WinSAMM gave room to SECURITHOR  back in 2009. Now at version 2.1 SECURITHOR brings new features such as Virtual Panic Buttons, Patrol Dispatch, Web Access for subscribers and Weboperator.

No Monitoring software company can say it has more installations and customers as varied as MCDI.

We are great at what we do

We concentrate on what we do best: Alarm receivers and Monitoring Software.
It’s not a hobby or a passing thing. We are doing it since 1994 and continue at our Montreal offices under our original management.

Many thousands of installation later we are still doing it and we still talk to original customers.

Several distributors are partners since the start. Stratel from Malaysia, Syscom from Mexico have been partners with MCDI for nearly 20 years.

MCDI regularly exchanges with industry leaders to make partnerships, especially in the field of IP receiving and video integration.
