Computer Revolution: The Story of the VPD’s MDT Pilot Program

Policing is not a word often thought synonymous with cutting-edge technology. Television crime dramas have played up the image of lone-wolf detectives, who favour instinct and “gut feelings” over fancy gadgets. The reality is that modern police agencies rely heavily on technology to do their jobs.


Historically, the Vancouver Police Department (VPD) has always been among the first to adopt new technologies, from motorcycles and traffic lights to call boxes and two-way radios. But in 1979, the Vancouver Police made an incredible leap forward when they installed computer terminals in patrol cars, something that would not become common practice among other police agencies for almost another decade. 


In the late 1970s, the computer industry was going through a time of rapid innovation. The personal computing race was in full swing and advancements in digital networking connected people like never before. Computers were finding their way into homes and workplaces, as components became cheaper, more capable and more user-friendly.

It didn’t take long before police agencies took notice of the computer revolution happening before them; nor did it take manufacturers long to realize the untapped potential of the first-responder market. As early as 1976, tech firms were designing in-car computers known as mobile data terminals (MDTs), which were capable of communicating with a central dispatch centre remotely. 


This technology caught the attention of the then less than a century old VPD, who had just finished building a state-of-the-art radio communications centre at their Main Street headquarters. Plans were made to continue the modernization of the communications centre so that it would be equipped to handle computer-aided dispatch and communication with MDTs by 1979. This plan was supported financially by grants from the City as well as the federal government, totalling over $600,000. The Canadian Government’s investment was largely allocated for the development of generalized software that could be used for other applications outside of policing. 


In 1978, in preparation for the eventual arrival of MDT units, the VPD purchased and installed a minicomputer at a cost of just under $140,000. Minicomputers were like mainframes, except they didn’t cost millions of dollars and take up the space of an entire room. The VPD minicomputer functioned a lot like a modern server, which once operational, would be able to manage data requests received by MDTs in the field.

After three years of laying the groundwork, in 1979 the VPD installed Motorola D-1118 MDTs into twelve cruisers. This initial roll-out of twelve units acted as a trial period so the VPD and City could gauge the value of
