IVS - Intelligent Video Surveillance
About
The Face Capture, Perimeter Protection, and IVS functions cannot be used at the same time, only one
Analytics+ or IVS function can be used at a time. In addition, the Smart H.265+ and the Smart H.264+ cannot
be used simultaneously with either an Analytics+ or an IVS feature.
- After smart codec is enabled, the device would stop supporting the third bit stream, ROI, and smart event detection, and the actual interface shall prevail.
- The "Loitering Detection" IVS rule is present on several Dahua North America devices at this time. However, this feature does not currently work, and is not advertised as a feature in any of the spec sheets.
Setup Suggestions
- The target should be less than 10% of the image.
- The target size in the image should not be less than 50×50 pixels.
- Brightness difference between the target and the background should not be less than 10 greyscale.
- The target should be continuously present in the image for no less than two seconds, and Event 134 the moving distance of the target should be larger than its width and no less than 15 pixels (CIF image).
- Reduce the complexity of surveillance scene as possible as you can. Intelligent analysis function is not recommended to be used in scene with dense targets and frequent illumination change.
- Avoid areas such as glass, reflective ground, water surface, and areas interfered by branch, shadow and mosquito. Avoid backlight scene and direct light.

| Tripwire
|
Error creating thumbnail: Unable to save thumbnail to destination
|
Premium IVS
|
Tripwire will detect if there is any object crossing the warning line, it can support different direction selection, such as A->B, B->A and bidirectional, and it can activate record , snapshot and alarm according to the judgment result
|
|
|
| Intrusion
|
Error creating thumbnail: Unable to save thumbnail to destination
|
Premium IVS
|
Intrusion is used to detect that some sensitive areas can’t be casually entered, exited or crossed in the monitoring scenario, it will trigger device alarm if the target object touches the detection line.
|
|
|
| Abandoned/Missing Object
|

|
Premium IVS
|
Abandoned/missing function is used to detect if there are people, vehicle and objects abandoned or missing in some areas in the monitoring scene; it can trigger an alarm when the target object stays or is missing for a time which exceeds the desired time.
|
|
|
| Scene Change
|

|
Premium IVS
|
Scene change function is used to detect abnormality of monitoring scene, such as camera being blocked, moved, intense light change and so on. The intelligence library will make comparison between the original picture and the picture of the camera which has been blocked or moved, and judge if there is similarity; it will generate alarm if there is no matched similarity

|
| Auto Tracking
|

|
Advanced IVS
|
PTZ tracking is an innovative feature that transforms manually controlled PTZ cameras into automated tracking systems that keep an moving object in focus and centered in the frame. It follows the object where stationary cameras would lose the object once out of the fixed cameras field of view.
|
|
|
| Smart Tracking
|
Error creating thumbnail: Unable to save thumbnail to destination
|
Premium IVS
|
Smart tracking is the linked monitoring between the PTZ camera and other devices, such as Radar and Thermal camera. When the camera detects the target, it sends signals to the PTZ camera for tracking.
|
|
|
| Thermal Camera IVS
|

|
Premium IVS
|
In some special environment, the Thermal camera can realize some IVS function that the normal cameral can’t, such as the object missing/object abandoned/intrusion/tripwire

|
|
| Face Detection
|
Error creating thumbnail: Unable to save thumbnail to destination
|
Advanced IVS
|
Face detection is to detect if there is any human face appearing in the video, and capture the face then send it to the NVR for analysis and processing, it can activate snapshot, record and alarm.
|
|
|
| Face Recognition
|

|
Analytics+
|
Detecting whether there is one face in the video image, and extracting a small size of the face, then send to the back-end for analysis, it can link to the fast capture, record and push alarm.
|

|
| People Counting
|

|
Advanced IVS
|
Provides people counting, region people counting, linkage alarm, and statement generation functions.
|
|
|
| Perimeter
|

|
Analytics+
|
Dahua Perimeter Protection technology can recognize human and vehicle accurately. In restricted area (such as pedestrian area and vehicle area), the false alarms of intelligent detection based on target type (such as tripwire, intrusion) are largely reduced.

Advanced IVS
|
It is used to detect the level of motion of moving objects in a certain time. Supports the statistics of the cumulative population density within the set time range, and displays in space with different colors.
