On 13 June 2014, Canon announced it had acquired Danish IP Surveillance VMS software company Milestone Systems. Milestone provides open-platform software to allow video management from various vendors in a single interface; therefore the company will operate as a separate entity. On 10 February 2015, Canon announced that it had intentions to buy Swedish Security Camera maker Axis Communications for $2.83 billion. On 23 February 2015, Axis Communications reacted to this news and confirmed that it had received a purchase proposal from Canon. The purchase was effectively completed in April 2015.
