Glossary

Anti-dither - How many alarm events can occur in the designated time (in seconds)

Period of time the alarm signal lasts (in seconds). This time does not include latch time. During the alarm process, the alarm signal can begin anti-dither time if the system detects the local alarm again. The screen prompt, alarm upload, email and etc. will not be activated.

Example of anti-dither

For example, if you set the anti-dither time as 10 seconds, each activation will last 10 seconds. During the process, if the system detects another local alarm signal at the 5th second, the buzzer,tour, PTZ activation, snapshot, and record channel will begin another 10s while the screen prompt, alarm upload, and email will not be activated again. After 10s if the system detects another alarm signal, it can generate an alarm since the anti-dither time is out

Latch - Delay (in seconds) before the system begins detecting for the same alarm/event
Show Message - The system will display a message at the local monitor

Example of message displayed

Post-Record - Delay recording for a specified time after the alarm ends
Tour - When an alarm occurs, the NVR local interface displays the tour image of the selected channels
Picture Storage - When an alarm occurs, the NVR device triggers snapshot for the selected channel
Buzzer - NVR will trigger internal buzzer when alarm occurs

IVS Recording

Analytics+ and IVS Infograph

Name	Type	Description
Tripwire	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	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	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	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.
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.
Heat-map	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.
LPC & LPR	Premium IVS	Analysis the traffic situation according to the traffic flow
