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

|
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

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
|

|
| 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.
