Providing round-the-clock protection of coastal areas or infrastructure against asymmetrical, stealth and non-cooperative threats
In this configuration, the group of objects that could be detected is wide and varied (boats, jet skis, kayaks, swimmers, drifting objects and debris, among others), and they have similar characteristics in that they are generally too small to be detected by a radar and are not fitted with AIS transponders.
Surveillance teams are made up differently depending on the infrastructure, and their size can range from zero (for a small marina at night) to large teams of specialised individuals (major maritime ports). In all cases, there is a need for effective, ongoing surveillance, either to replace an operator (for example, when the service is not active, such as at night) or to provide pertinent alert information that will make it possible for the protection team to act appropriately and judiciously.
The zones to be monitored may be of different sizes, they may be hidden from the harbourmaster’s office or security centre or they may be excluded from the coverage area of the surveillance radar. The flexibility provided by the cameras, which can be installed easily at any location within the port or zone to be monitored, is unique; the strength of the ASV software is that it offers the intelligence that transforms these cameras into genuine detection sensors wherever it is installed.
Several solutions are generally possible to cover these types of requirements in terms of the type and number of cameras. They depend to a large extent on the geographical and local configuration of the zone to be monitored and on the requirement stated by the user (surface area and detection range to be covered, duration of detection, identification capabilities).
By way of example, if the requirement specifically concerns surveillance of an interior basin (short range, permanent), a series of fixed cameras appropriately located and connected to the surveillance center by wireless connection will be sufficient. If the requirement is for surveillance of the approach to a port, with a need for a permanent video feed and identification of incoming ships, the system introduced should comprise a series of fixed, semi-panoramic or panoramic cameras combined with one or more pan-tilt-zoom cameras.
The compromise in this type of configuration is to find the combination of cameras that enables satisfactory detection and an adequate identification capability while still remaining within a reasonable budget.
