CMS HUB

Data gathered by CMS HUB are shared and visualized in client application - CMS Professional 4. CMS HUB integrates also a server proxy module, which is used as proxy in communication between client stations and VMS/NVR system. If VMS/NVR software is avaiable in WAN network, then there is no need to give access to the internet to client stations, they can connect to video servers via CMS HUB thanks to proxy function.

Below diagram describes how system works.

Basic functionality of CMS HUB:

• Central recorders (VMS/NVR) list
• Global users list
• Proxy module
• Event list from recorders
• Task scheduler
• Reports module
• Access control module

CMS HUB contains recorders list, which may be combined into groups. VMS/NVR recorders sends periodical reports to CMS HUB with the status presented on the list: 

• State (online / offline)
• Application running time
• System running time
• Recordings duration
• Reserved disc space
• Used disc space

CMS Professional 4 clients stations are able to connect to video recorders in order to video preview (live/archive), browsing events locally stored on recorder (LPR, VCA, POS), recorders settings.

Data stored by CMS HUB:

• VMS/NVR state on/off
• Link down with VMS/NVR
• Camera: signal lost, tampering (depending on hardware)
• Input/Output alarms
• Users: logging user to recorder
• System: system time changes, critical errors (file system errors, bad sectors e.t.c.)
• Video backup complete
• Operational recorder’s errors
• Configuration changes
• Module contributes browsing of all stored events by many filters
• Critical errors are additionally marked on the list
• Additional system events (sent to CMS HUB) can be created in order for local recorders events (POS, VCA, LPR etc.)

Reports module is used for statistical data presentation. Data is gathered from clients VMS/NVR to CMS HUB and its available for local browsing. Reports include also:

• POS: value of sold products by the name, cashier, number of merchandise scans, cancelled transaction per cashier
• LPR: counters of passing cars
• VCA: number of detection alerts for relevant types of events
• Task scheduler module
• Availability to run certain action users configurable (run program, e-mail sending) in response for particular event s from recorders
