The invention concerns an installation for the high-speed acquisition of acquisition data via an Ethernet network (2) with several nodes (N), where at least one of the nodes of the Ethernet network constitutes a client/server detection unit (3) with at least one detector (4) delivering acquisition data.According to the invention each detection unit (3) includes: self-triggering resources for reading the acquisition data so that the said detection unit (3) is able to operate independently, reading and processing resources that are independent of the other nodes, resources for transmission of the acquisition data via the network (2), to at least one other node (N). and a clock unit allowing correlation between the clocks of the detection units, where each clock unit has resources for receiving a clock synchronisation signal, resources for transmission to the transmitting clock unit, and resources for processing the encoded instructions.
