Acoem Blast Monitoring Specifications Acoem's Blast Monitoring System is available as a fully-integrated package for long-term rental with our expert team managing the provision of blast data remotely. The system consists of remote blast monitoring stations, called Dynamates which are continuously supervised by a remote software package known as Dynamaster on our server at the Acoem Australasia Head Office in Melbourne. Blast results are automatically collected from the stations, collated and then made available within minutes of the blast. You can then view blast results, produce reports and interact with the server software via the Dynamaster web portal. FEATURES • Easy post-mount installation • Solar powered system with battery • Remote communication over GPRS, 3G or 4G • Results & data are available only to authorised users & can be downloaded or viewed anytime at work, home or on the road. All you need is access to the internet • Automatically notification of blast results by SMS, email or both within minutes of the blast • Event-file generation & retrieval • No minimum time between event captures • Advanced triggering methods ensure 100% blast capture can be achieved • Advanced buffering methods enable the capture of results up to 25 weeks after a blast, even if an automatic trigger did not occur • Acoem blast monitors are triggered daily to test their recording status & download capability.
