FAQ

For 8-ports model, it supports upto 8 IEEE 802.3af and upto 2 IEEE 802.3at.

For 16-ports model, it supports upto 16 IEEE 802.3af and upto 4 IEEE 802.3at.

Frequent Power On/Off operations are difficult to recommend

No, you can't use.

Up to 16

We provide 'AE Target Gain' function as 'Auto Gain Control'
You can set 'Camera Setup -> Video Tab -> Exposure -> AE Target Gain'

Users can generate the "Email" and "Callback" event when the SD card is in/out
"Camera Setup ➔ Event ➔ System Event ➔ Disk In/Out"

Since Person Match service uses recording(= Playback session) serssion of Recorder. 
so, In ISS recording service, upto 10 session can be available, 
In NVR side, upto 2 session is available. 
however, If a Client is using the recording session of NVR, 1 Person match service is available.
 

No. Depending on your situation, you may want to Detach > Install on a different server. / However, since it is a cost issue, I would like to recommend installing it in the PM server as much as possible.

No, Recorded Footage mode does not use MariaDB

Yes, if Person Match is not set, IDLA is not stored in MariaDB.

Both services are using the same VA Engine(called IDLE), there is no difference in recognition rate, and the specification is the same as upto 50 object simultaneous monitoring. However, note that the optimal performance is upto 16ch.
 

Person Match Service Licenses
The Video Analytics (IDLA) and Person Match Services use and share the ISS VA license. If you are already using the IDLA, the PM service is provided as a free upgrade. 

Even when adding multiple PM service in a single Admin Service, it is used as the total number of channels purchased.
 
As PM service is in Federation, the IDLA license for PM service should be included to Federation license, 
As PM service is in Admin, the IDLA license for PM service should be included to Admin license.
 

Person Match Service at Federation service
Person Match is also available in Federation service.
As mentioned above, when performing PM search, data traffic increases instantaneously because the PM service directly accesses multiple recorders or recording services to retrieve and analyze data.
In other words, it should be used in a space with sufficient bandwidth of the network. In other words, if you need to install PM service in the location where Federation is installed, it is necessary to review beforehand whether the network bandwidth and latency are sufficient.
However, when building a system, you need to understand the operation method and data flow in order to build it correctly. 
Case1: When FED (Federation) has a PM license
Case2: When ADM registered in FED has a PM license

Case1: When PM service is registered in FED
PM search can be done at ISS FED CLIENT. ISS FED CLIENT can perform PM search for all cameras.
 
However, if the network bandwidth between the recorder (ADM) and PM (FED) is insufficient due to the system structure, the search speed may be quite reduced, so please be careful.
For example, if the bandwidth between a bank's ATM and the monitoring center is very limited, it can be a problem when performing PM search.
In this case, Case2: When ADM registered in FED has a PM license.
In this case, Federation should have IDLA(PM) license.
As many as IDLA(PM) license applied, user can search the number of channel(IP camera)
 
Case2 : When ADM registered in FED has a PM license
As above, if the bandwidth between ATM and monitoring center is low, Case 1 is not appropriate.
In this case, while building PM service on the ATM side, it is built on site to secure sufficient bandwidth for VA.
 
Note: In this case, PM search cannot be run for the camera of ATM2.
For PM service, PM serivce must be installed in the admin service.
In this case, Federation dose not need to have IDLA license, but Admin license should have it.
(With above diagram, ATM2 site cannot use Person match service, because there is no Person match service installed)

Q: I am monitoring real-time video over 144 channels by connecting 4 monitors with Intel i7 + Quadro P1000 (GPU) configuration.
By the way, up to the 2nd monitor is normal, but from the 3rd monitor, the video is cut off. Why is that and what should be done?

A:
1) Intel i7 CPU
+) i7 CPU also has a grade, but the general i7 has 4 cores (Quad Core).
From a multimedia data processing point of view, this is an intermediate specification.
+) CPU selection is very important in real-time monitoring operation of more than 144 channels (cameras) in a configuration of 4 monitors.
2) Quadro P1000 GPU
+) The P1000 has the advantages of low power and easy multi-monitor configuration, but it is a low-spec GPU.
+) It is a better GPU than the GPU used in development, so it is difficult to conclude that the current information is the cause of the issue.

** Issue identification
+) If the CPU occupancy exceeds 90% and the phenomenon is reproduced, there is a high probability that it is a CPU issue.
+) CPU usage is less than 85%, but if the phenomenon is reproduced, there is a high probability that it is a GPU or MEM (out of memory) issue.
In addition to +), it is necessary to review the overall operating environment (OS / CPU / MEM / GPU / Device Driver / Etc)

** check item
1) Check camera stream settings and dynamic multi-stream control configuration
2) Check the camera stream encoding codec (H.264)
+) H.264 has much less decoding load than H.265.
+) It is recommended to use the H.264 codec for the stream used for multi-channel monitoring.
3) Activating camera settings intelligent codec
4) Default value is recommended for Client S/W setting (Preference - Video Enhancement)
+) In a low-end GPU environment, it is necessary to check the phenomenon depending on whether High-Quality Downscaling is used.

This mode is almost the opposite of ‘Pre-Processed Footage mode’ in operation.
When PM service is executed, it directly accesses the recorder or Recording service, accesses the recorded data and performs analysis (IDLA).
Also, this mode can do PM search with any camera (the biggest difference from Pre-processed Footage mode)

Advantages :

‘Pre-Processed Footage mode’ costs a lot when building a service, but Recorded Footage mode doesn’t require IDLA VA service and MariaDB for pre-processed VA metadata like the above configuration. (In other words, the construction cost is lower than the Pre-Processed Footage mode.)
So, if the cost of H/W is burdened, you can use this mode.
