This new integrated solution builds on the unique performance of Obzerv's flagship product the ARGC-2400 and Flir's ThermoVision 2000/3000 camera.

The cameras are installed together on the same post. The ThermoVision 2000/3000 camera is used for its detection capabilities to scan the horizon. Once a target is detected the operator uses the ARGC-2400 to classify and identify the target.

Obzerv's ARGC-2400/ThermoVision solution in action

Using Thermal Imaging capabilities of the solution the operator detects a large ship cruising off the coast at 20ákm. The next step for the operator is to engage the Range-Gating Imaging function. Once enabled, the Ranged-Gating capabilities are allowing the operator to recognize the ship at 20ákm, read her name at distance less than 10ákm and even assess the height of the flotation line, hence, becoming fully empowered to take the appropriate decision and action.

Without the appropriate information, it is impossible for an operator to properly assess a given situation. Obzerv's ARGC-2400/ThermoVision integrated solution is responding to the challenge and empowering operators with time critical information provided by the unique combination of Thermal & Ranged-Gating Imaging.
