67 Software Q. What is Wibu Key? 2015-07-06
A.

Wibu key is a USB license key that comes with ISS. You always need to have the Wibu key plugged in the server running its corresponding service(s) at all times, or else, ISS System will stop working immediately.

66 Software Q. Can I use ISS systems on VPN? 2015-07-06
A.

Yes, but the network bandwidth and network delay overhead on the VPN may become a problem. It is advised to isolate IP video stream traffic within one subnet as much as possible and limit VPN access to ISS client software for casual use only.

 
65 Software Q. Can I use NAT routers and WAN connection in ISS system? 2015-07-06
A.

ISS system typically would have many megapixel cameras. If you need to access the ISS system from the WAN side, there are a few things that you need to understand:

 

  • IP video stream isolation

    • install all IP devices and services on one Gb LAN

    • so that all recording traffic is isolated in one Gb LAN

    • for ISS Client access, you may want to use Dynamic MultiStream Control[1] or Motion Adaptive Transmission (MAT)[2] feature if your IP camera supports it to reduce the Live watch network traffic for the IP cameras/video encoders supporting these features.

  • NAT traversal

    • External IP Address/port setup

      • you have to use ISS Service Manager on each server to configure External IP address for each service.

      • refer to ISS Service Manager section to find out how to do this

      • other ISS services or ISS Clients will use these external IP address settings if they are connecting from WAN side of the NAT router

    • Port forwarding is required for the followings:

      • Admin service (TCP 11001): for login and to get connection information for the registered ISS services and devices

      • Recording service(s) (TCP 11002): to access the recorded video. if you have multiple Recording services, you will have to use a different port for each service, and forward the corresponding port respectively

      • (Live) Streaming service (TCP 11003): to subscribe to live video streams. the target devices have to be configured to use Streaming service. If you have multiple Streaming services, then you have to use a different port for each service, and forward the corresponding port respectively

      • Monitoring service (TCP 11004): to subscribe to events, required for all event-related operations in ISS Client such as Event spot, Map, Event handling, etc

      • Video Analytics service (TCP 11007): to subscribe to VA events. Typically, you do not need to forward the Video Analytics service (TCP 11007) port because only ISS (Event) Monitoring service needs to access VA services and they are installed in the same subnet.

      • Backup service(s) (TCP 11005): to access back up video. if you have multiple Backup services, you will have to use a different port for each service, and forward the corresponding port respectively

      • Federation service(s) (TCP 11001): for login and to get connection information for the registered ISS systems


 

 


 

[1] You can use ISS Client to switch between different IP video streams for different layout automatically by assigning different video profiles for different IP video streams. Your IP camera/video encoder must support this feature. Check ISS Client->Preferences->Video Enhancement section to enable it.

 

[2] This is an IP camera/video encoder feature. IP camera/video encoders can be set to decrease the frame rate (image per second:ips) if they sense there be no video motion detected in the scene.

64 Software Q. What about Network environment for ISS? 2015-07-06
A.

It is strongly recommended that you use a LAN environment with the Gigabit network for all your ISS systems. If you use a 100Mbps network, you can only have a handful number of IP cameras.

For example, 2MP H.264 real-time (30ips) IP video stream can reach up to 4~12Mbps. If you are recording 10 of them and trying to do live monitoring, the 100Mbps bandwidth would not be enough.

 
63 Software Q. What about server specifications for ISS service and client software? 2015-07-06
A.

Please refer to the manual for the specifications. The general rule of thumb is

    (Live) Streaming service uses a lot of bandwidth and CPU resources

    Video Analytics service uses a lot of CPU/Memory resources

    Admin or (Event) Monitoring services are moderately resource-demanding

    Recording services require high-speed storages

    PCs to run ISS Client software need to have a good VGA card, and CPU to decode multiple streams of IP video streams

 
62 Software Q. Where do I install each ISS service? 2015-07-06
A.

It depends on your budget. ISS System is very flexible in terms of where to install different services. Ideally, you may want to have one server running only one service. Typically, you will run Admin/(Event) Monitoring services on one server, and Recording, (Live) Streaming and VA services on three separate servers respectively.
But if your system is 32ch max, you may run all the services: Admin, Monitoring, Recording, Streaming on one server, and VA service on another server. VA service takes a lot of CPU resources[1]. If you are installing multiple services on one PC server, such as (Live) Streaming service and Recording service on the same PC server, you need to assign different (RTP) incoming port ranges for them. Refer to the Incoming port range in the glossary.

 

 

 


 

[1]  4 core CPU can handle up to 8ch in VA service

 
61 Software Q. What Port does Admin service use? and what about NAT traversal? 2015-07-06
A.

ISS Admin service uses TCP 11001 port. If the service is behind a NAT router, you need to port forward TCP 11001 on the router, so that ISS Client and other services can connect to it.

You can configure this port number on the server running the service using ISS Service Manager.

 
60 Software Q. What happens if ISS Admin service crashes? 2015-07-06
A.

All ISS client software will stop working.
(Event) Monitoring, (Live) Streaming and VA services will stop working. Backup service will stop working. Federation services will not be able to work with the ISS System with its Admin service crashed.
However, Recording service will continue to work, but it will be able to record Event-related IP video streams only for the IP devices registered to itself only. This is because, for cross Recording service boundary event associated recording, IP camera events are collected by (Event) Monitoring service and then routed through Admin service to the other Recording service. This can not be done because the Admin service is crashed.

 
59 Software Q. What happens if I install more than one ISS Admin service? 2015-07-06
A.

Nothing. You are just creating a new ISS system. You will need to have a new ISS license, or it will be running in demo mode. You may be able to register IP devices, but recording may not work. Because if an IP camera using ISS protocol is registered to two different ISS Systems, Recording may not work properly because two ISS Systems will be competing to establish a recording session with the IP camera. IP cameras using ISS protocol allow only one recording connection session. The Recording service that establishes the recording connection to the IP cameras will keep the recording session. The other Recording service will keep trying to connect to the IP cameras and fail.

 

58 Software Q. What happens if I uninstall ISS Admin service? 2015-07-06
A.

Don’t do it. You will lose everything until you restore the iexp Service Database file to restore all the services and device list.

57 Software Q. What happens when I delete a registered service from Admin service? 2015-07-06
A.

All other services will be decommissioned immediately. For example, in the case of Recording service, the recording will be stopped immediately, and ISS Client won’t be able to access the recorded video on the decommissioned Recording service. The recorded data will be preserved in the decommissioned Recording service. If you have a backup of iexp file, you may be able to regain access to the recorded video. You need to re-register it to the Admin service, and then reload iexp file to it.

56 Software Q. All the services are installed, and registered to Admin service, how do I configure them? 2015-07-06
A.

Use ISS Setup,

    Log in to the Admin service with a user account that is a member of a group with proper Setup authorities like ISS service setup and ISS schedule setup

    Select the Services icon to see all the registered services.

    Double click service or use [/] edit icon to configure the selected service

Typically, you will be firstly adding/registering IP devices, nextly assigning them to different services, and then configuring the services, such as setting up Storages for Recording service, configuring VA parameters, etc.

Refer to each Service section for further service-related details.

 
55 Software Q. I can use the ISS System without any problem, but I cannot remotely setup the IP devices. What is wrong? 2015-07-06
A.

If you are connecting to ISS Admin service behind a NAT router using ISS Setup, IP address scope issue may arise: IP devices and ISS Admin service are running in the same subnet behind the NAT router, but ISS Setup is connected from the outside of the NAT router. In most of these cases, the registered IP addresses of the IP devices are private, and ISS Setup won’t be able to use the private IP addresses when it is connected from the outside of the NAT router.

You can address these issues for IP cameras/video encoders using ISS protocol and ISS compatible DVRs/NVRs by using FEN and forwarding the corresponding ports. But when you have many different IP devices, even this approach is not manageable.

 - configure all IP cameras/video encoders using ISS protocol and ISS compatible DVRs/NVRs to use FEN

 - forward the admin port for each of them

 - register them to ISS Admin using FEN names

Typically, for security issues, it is advised to run ISS Setup in the same subnet where the IP devices are running. 

 

54 Software Q. All the services are installed, and IP devices are added/registered to the ISS Admin service. Can I remotely configure the IP devices? or Upgrade the firmware? 2015-07-06
A.

Use ISS Setup, and you can remotely configure the following devices:

  • IP cameras/encoders using ISS protocol

  • ISS compatible DVRs/NVRs

  • ONVIF compatible IP cameras[1]

  • compatible 3rd party IP cameras

You can upgrade the firmware of the following devices:

  • IP cameras/encoders using ISS protocol

  • ISS compatible DVRs/NVRs

 

 

 


 

[1] Only supporting the setup of the ONVIF compatible parameters exposed by the ONVIF devices.

 

53 Software Q. How do I add/register services to Admin service? 2015-07-06
A.

When you install ISS services[1] on one or more servers, the ISS Setup wizard will ask for the connection information of the Admin service during installation. Using this information, each service will report itself to its Admin service. An admin user will have to register these services to include them in the ISS System.
Use ISS Setup for this. Launch ISS Setup, and log in to the Admin service. Select the Services icon and use + icon to register these services.
