Surveillance beyond security
November 2017, CCTV, Surveillance & Remote Monitoring
Until now, level of detail has been the key quality parameter for surveillance cameras, as clear images at all times was the most important feature for security. True, security personnel must see all relevant information in great detail to react quickly and take appropriate action. But what if a moving object leaves the camera’s field of view?
The AUTODOME IP family of pan, tilt and zoom (PTZ) cameras enable users manually to keep track of persons of interest as they move – even at speed, far beyond a fixed camera’s field of view.
This illustrates how the new AUTODOME IP cameras are improving video security. What opens a new chapter in the usage of video cameras is their built-in video analytics as a standard. The new IP cameras from Bosch now add metadata to all captured video images. This data can be used to improve security by automatically alerting users once pre-defined criteria are met or for other uses beyond security. For example: enforcing traffic regulations, enforcing no-parking zones, detecting vehicles driving the wrong way and delivering occupancy data (the number of vehicles entering or leaving a parking garage) for smart, more efficient parking.
The built-in Essential Video Analytics enables the AUTODOME cameras to understand what they are seeing. They generate metadata to add sense and structure to the video footage, instead of just capturing and storing video images. They not only detect objects, they deliver associated data like size, speed, shape, direction, and colour. They automatically distinguish between the object types such as person, car, bike, motorcycle or truck.
Because it’s possible to set certain alarm rules, such as someone approaching or climbing over a fence, security personnel are alerted the moment the alarm rule is triggered. It can even be configured to recognise changes in speed (running), shape (crouching) or aspect ratio (falling). When searching for evidence, metadata in combination with the forensic search functionality allows instant retrieval of relevant footage from hours of stored video.
The AUTODOME IP 4000i is designed for indoor use. It comes with full pan and tilt control, plus 12x optical zoom that identifies fast-moving objects in 1080p resolution at distances of up to 88 metres at 60 frames per second.
For indoor and outdoor applications with a larger surveillance area, there is the AUTODOME IP 5000i. With its 30x optical zoom, 1080p resolution and 60 frames per second video, fast-moving objects can be identified at up to 190 metres during daytime, even in challenging lighting conditions.
For larger distances and complete darkness, there is the AUTODOME IP 5000i IR. It performs identically to the AUTODOME IP 5000i during daytime, and at night identifies objects at up to 150 metres. Its built-in, infrared beam ensures optimum illumination regardless of zoom level.
All 4000i and 5000i cameras from Bosch offer Intelligent Dynamic Noise Reduction and Intelligent Streaming, now also combined with H.265 video compression. Depending on the content of the scene, this reduces bitrate by up to 80%. It helps to keep video data manageable, while substantially reducing network strain, storage requirements and costs, without compromising functionality and image quality.
