How to monitor multiple security cams connected to the server. How to create a time lag to switch between those.

[alxkls]

are you sure this is in any way related to databases? what language will you be using? how are the cams connected to the server and which port and protocol do they use?

I suggest hiring a Security professional for your needs, this is not a database query (pardon the pun .. lol).
As I use to work in this area myself I can suggest some top quality CCTV hardward and software that can provide the functionality you require. This is not something programmers would be doing for free at any level.

How to monitor multiple security cams connected to the server.

1. Hire a gaurd with the correct certification to work control rooms.
2. Sit there yourself and watch lots of T.V's or jack them though one BOX and let it auto cycle throu each feed displaying it on one T.V (problem is you are no longer providing optimal security measures).

How to create a time lag to switch between those.

1. The Time lag as suggested above will be a specialised CCTV box that auto cycles and even burns to disc on the fly all other feeds that are not being monitored physically with a storage capacity of normally 24 hours for upto 'X' feeds before it wipes the disc and records again

Good luck

Well, I can not name the software but I have seen the display of all places captured by several cameras, at the same time at the same screen(splitted in to several windows). The software comes with cameras.
