What are Dahua Ultra-Smart Features?
Dahua Ultra-Smart Solutions not only provide ultra high-definition image quality, but also bring more professional, convenient and intelligent video surveillance experience, driving a comprehensive upgrade with smart and simple functions that can better secure and protect your property.
Many Dahua cameras have a built-in video analysis based on intelligent algorithms which can be configured to trigger events based on Tripwire, Intrusion and Abandoned/Missing. These events can quickly and accurately detect targets in a specific area enhancing monitoring efficiency. Also available is the ability to support face detection, this can quickly capture a face and create an event on an NVR. In addition the camera also supports intelligent tamper detection, through dramatic changes in the scene it will send out warning information to ensure effective monitoring.
Region of Interest (ROI)
Region of Interest allows cameras to enhance image quality and focus on the chosen region of interest by decreasing non-ROI's image quality to acquire more computing power and bandwidth.
Defocus detection detects when the image quality of the video is being compromised. Defocus Detection has the ability to recognise when the image loses sharpness or becomes unclear due to changes in the camera lens' focus. From this the camera can alert users and take a number of actions, including; recording, snapshot or alarm according to the judgemen result.
Face detection is to detect if there is any human interaction (facial) appearing in the video. From this, it will trigure the camera to take a snapshot and forward it to the NVR for analysis and processing. It can activate snapshot, record and alarm.
Intrusion detection is to detect if there is any object entering/leaving the focused area, an alarm will be triggered when crossing the perimeter set. This can they activate record, snapshot and alarm according to the judgement result.
Scene change has the ability to detect if a camera has been tampered with i.e. if the camera has been moved or covered resulting in a change of scene. The intelligence base will compare the images before and after the change and make a decision whether to generate an alarm.
Abandoned/Missing detection can be set to automatically detect missing or abandoned objects in complex environments.
Ultra-Smart IP cameras can detect intruders crossing a tripwire set by the user. It will either trigger an alarm, take a snapshot or sound an alarm when the target passes through according to the judgement result.
Fisheye & Dewarp
Fisheye cameras providing 360 degree viewing angles can be dewarped to display multiple 16:9 or 4:3 screens and 180 degree panoramic views. This can be achieved using NVRs that support the dewarping feature and or via Smart PSS. DMSS & Smart Player.
Auto tracking is a feature in some models of PTZ cameras that allows the camera to automatically follow targets without operator intervention. Auto tracking can be configured to follow targets in a set position or combined with smart features such as Tripwire & Intrusion, to follow targets that trigger these types of events.
Dahua's starlight technology is ideal for applications with challenging lighting conditions. Its low-light performance delivers useable video with minimal ambient light. Even in extreme low-light conditions, starlight technology is capable of delivering colour images in near complete darkness (0.005 lux).
Multi-lens cameras offer a 180 degree angle of view, allowing one camera housing with multiple image sensors and lenses to cover a wide area without the need for additional cameras.
Zoom can relate to either to a mechanical (optical) or digital zoom feature. Optical zoom allows the camera lens to adjust its focal length to zoom in on areas without degrading the picture quality. Digital zoom artificially adjusts the focal length by making the picture quality bigger in increments, reducing the quality of the image at each increment (zoom varies dependant on models).
