Two nos. of SAN/NAS of size 10 TB usable each against item no.14 of Schedule-B in Annexure-C will be used in OCC for storing of sensitive videos from selected cameras for analysis etc. Although RDSO specification does not include NAS specification, the bidder can offer NAS of reputed make for consideration. The station level recording of nearly 30 cameras will be made in the Storage Server, for which 4 TB HDD has been specified. Metro railway is well aware of the limitation of the storage space under the scope of the present tender and hence it will have to be satisfied with a recording of minimum seven days at station level. There is no such duration stipulation for central storage, as it will depend on strategic selection of cameras on a day-to-day basis.

We assume servers mentioned in Sr. No.6 are For VMS and video analytics requirement.But Apart from them there should be client Workstations on each station for connection Display monitors which are missing from the BOQ please clarify.
Please note that in CCTV it is recommended To have separate workstations for monitoring Servers should not be used for video display Even RDSO recommended the same.

All the cameras will be recorded at their respective stations. With each station having 30 camera. Then what is the purpose of asking for another set of 763 recording and analytics Licenses? If it is intended to record all the Cameras parallel in central place also than you need 30 servers on central location as well. Please clarify.

The composite video signal coming from all the stations will be viewed and monitored at 5 locations, where it may be required to archive and analyze video signals also. Hence, the license for 763 cameras for five user. All the cameras may not be required to be recorded for all the time at OCC. For this, five to seven servers may be sufficient. If not, the bidder is free to bid for additional servers against Item No.23 of Part.-B of Schedule of Rates(Annexure-C)
