6.2 Analyzer Configuration

View the analyzer usage and change the analysis mode.

Analyzer is a smart chip used to process face recognition, perimeter protection, behavior analysis, ultra motion detection, people counting, etc. The analyzer capacity varies by NVR model, which requires you to allocate channels appropriately.

1. Go to Menu > VCA > Analyzer Config.

2. View the analyzer's capacity usage. The analyzer's capacity can be represented by the number of video streams or image streams it can analyze.

The following table describes the detailed analyzer capacity usage strategy.

Type Usage Description
Video stream analysis (NVR-side function)	10% (for each function)	Enabling each function in this category for a channel will consume 10% capacity: rat detection, fight detection, fall detection, no work clothes detection, no reflective clothing detection, smoke and fire detection, people flow counting, and mixed-traffic detection.For example, if you enable rat detection and fight detection for a channel; that's two functions, and it will consume 20% capacity.
Video stream analysis (NVR-side function)	10% (for each analysis model)	Enabling any or all functoins of a category for a channel will consume 10% capacity.• Category 1: No mask detection, no helmet detection, smoking detection, calling detection, no chef hat detection, and sleep on duty detection.• Category 2: Cross line detection, intrusion detection, enter area, leave area, absence detection, climbing detection, and long stay detection.• Category 3: Face detection and face comparison (NVR-side analysis).For example, if you enable no mask detection and no helmet detection for a channel, which belong to one category (category 1), and it will consume 10% capacity; if you enable no mask detection, no helmet detection, cross line detection, and climbing detection, which belong to one category (category 1 and 2), and it will consume 20% capacity.
Image stream analysis (only for camera-side face recognition)	5% Only camera-side face detection will consume the capacity of image stream analysis.• When the analyzer has sufficient capacity, enabling camera-side face detection for a channel will consume 5% capacity.• When the analyzer has insufficient capacity, camera-side face detection can be enabled, but it does not consume analyzer capacity. At the same time, other camera-side functions except the face comparison can be enabled and configured, as they does not consume analyzer capacity and their data are analyzed and reported from the corresponding IPC.

Takes analyzer 1 as an example. The analyzer 1 has been used for 2 video stream channels, which consumes 20% capacity, and can be still used for 8 video stream channels or 16 image stream channels. The VCA Config page shows the enabled functions.

4	ARRAY4	44644.13	Normal	RAID 5	1-8,1-13,1-14,1-15 1-2		-		None

Manually Create an Array

Manually create a desired array. Take RAID 50 as an example.

Note:

• To avoid wasting disk resources, please make sure all disks are used to create arrays. Disks that are not used to create arrays are unusable.
• No global hot spare disk will be created automatically if you create arrays manually. To ensure successful automatic array rebuilding and stable system operation, it is recommended to set a global hot spare disk.

• The capacity of the global hot spare disk must not be less than that of the smallest disk in the array.

• Go to Menu > Storage > Array > Physical Disk.

• (Optional) Select a disk and click 70 set it as a hot spare disk.

Note: If there are multiple arrays and you require highly stable arrays, you can configure multiple global hot spare disks. When multiple arrays degrade, the global hot spare disks are used to rebuild them in order of disk number. However, too many global hot spare disks may cause waste of disk resources, so please set them as required.

1. Click Create.

1. Enter the array name and select the RAID 50 type.
2. Select the number of sub-array disks.

Note: This parameter is only available to RAID 50 and RAID 60 due to different array creation principles. For example, RAID 50 is a combination of RAID 5 and RAID 0, and RAID 5 is the sub-array of it.

Type Number of Sub-array Disks Number of Disks Required
RAID 50 3 to 8 An integer multiple of the number of sub-	array disks. RAID 50 requires at least 6 disks.
RAID 60 4 to 8 An integer multiple of the number of sub-	array disks. RAID 60 requires at least 8 disks.

1. Click OK. Check the created array under the Array tab.

Rebuild an Array
