Hanwha Vision has launched a range of PTZ PLUS cameras with AI (artificial intelligence). The high-definition AI PTZ PLUS range is designed for large open areas such as airports, car parks, stadiums, city centres, and industrial estates, plus perimeters. The AI can reduce false alarms and allows the cameras to classify objects including persons, faces, vehicles (including vehicle type) and number plates.
This object detection and classification enables operators to search for footage of specific objects. With intelligent video analytics, operators can monitor for objects such as people entering and exiting a pre-defined area like a restricted office within an airport, or crossing a line, to detect when a person or vehicle has crossed a perimeter, for instance. Appear/disappear and loitering detection is also possible.
The deep-learning AI means irrelevant objects, such as waving trees, moving clouds or animals, all among the causesof false alarms with standard motion detection technology, are ignored by the cameras. The cameras feature auto-tracking, driven by the AI engine. With the ability to tell individuals and vehicles apart, the cameras automatically lock onto desired targets and track even small objects in challenging scenarios due to low-light and nocturnal settings. A missing object redirection capability can recover temporarily lost targets, allowing uninterrupted tracking despite unforeseen disruptions.
The range comes subscribed to an MQTT server that enables it to work with other devices and sensors in an installation, including Internet of Things (IoT) sensors. Information shared with the camera via the MQTT broker will cause it to react, such as panning automatically to a detected entry or exit to provide visual confirmation that a person is authorised to be in the area and then sharing an email report back to operators. Or, the camera can share information about an object detection event to the MQTT broker, to then trigger specific actions such as locking or unlocking a door, switching on lights or turning off the air conditioning.
The new 2MP, 6MP and 4K cameras can capture evidence-grade images of objects up to a distance of 200 metres away in all lighting, it’s claimed, thanks to adaptive IR. A focus save function, which can be applied to 32 pre-defined areas, means that the camera can come into focus when moved to a new position, again, regardless of lighting conditions. An extended tilt range of up to 110 degrees means that objects positioned above the cameras can still be seen.
The cameras have a pre-set accuracy of ±0.1 and can automatically detect if they are not precisely aimed at a specific field of view and correct themselves within one second, so that operators are receiving the best footage of a location.
Being some 65 per cent lighter than most PTZs, the X Series AI PTZ Plus line-up is designed with a focus on simple installation (with a single RJ45 terminal, for cable connection) and durability, the developers add. A flexible cable bush cuts out the need for additional waterproofing work, preventing water ingress.
Uri Guterman, Head of Product & Marketing at Hanwha Vision says: “The AI PTZ PLUS range underpins Hanwha Vision’s continued commitment to advancing the way businesses operate, by delivering high-definition visual data and AI insights that extend beyond traditional security.”
The line-up comprises nine models, that come in 4K/6MP/2MP resolutions with options for infra-red (IR) lighting and wiper. Visit HanwhaVision.eu/.
