Listed below is what we need to quote our end user (school)....if the setup is even possible.


110 Wireless IP Cameras (2.8Gbps)

DVR/Server/Routers

Any other necessary hardware


Does anyone have any insight on this topic?  I haven't had the opportunity to quote any surveillance systems this large before.


Thanks!

There are some challenges in reaching a 110 camera solution.  Things you need to plan for with a Cisco Small Business solution:


* You have two options for the wireless camera.  WVC210 & WVC2300.  For security applications include low-light & no-light (with IR illuminators) conditions, the best option is the WVC2300.  You can also customize the lens on the WVC2300 to match your field of view needs for each individual camera.  Both WVC210 and WVC2300 are indoor cameras.  If you need cameras outdoors, the PVC2300 and PVC300 are excellent options which support POE.

* For management software, all the cameras come with SWVMS16.  This has the ability to manage, view, record, and playback 16 cameras at once.  For a 110 camera solution, you'd need to deploy 7 windows computers running SWVMS16.  Technically feasible, but managing each application would a burden.  If you can break down the monitoring into sections/categories that might make this step easeier.  Even the common 3rd party Video Management Software from ONSSI, Nuuo, & Milestone don't scale to 110 cameras without having to buy their enterprise level central management system software.

* Besides the video management software, you'll need enough storage capacity to store the video.  This will depend on the complexity of the video stream (how well the codec can compress the data), resolution, and frames per second.  If we assume 250Kbps per camera x 110 cameras = 27500 Kbps total.  You'd need over 6TB of storage to hold just under 21 days of video.  You'll want to make sure the data is protected in a NAS or server with RAID.  You'll also need to make sure the NAS or server can handle the incoming bandwidth.  If not you'll need multiple storage devices.

* You need wireless access points that can handle the number of clients and bandwidth needed.  Will depend on physical layout of the 110 cameras.

* You need switches to connect all the access points to the network.


There is definitely alot to define in a solution this large.

Elizabeth,


That is a very big question with limited information.  What is the surveillance solution supposed to achieve?  Basic recording only and when something happens, you have recording to review.  Is someone going to be watching the video live?  Any remote live or recorded playback requirements?


The 2.8Gbps value listed.  What is that supposed to represent?  For 110 cameras, that would be 25Mbps.  Which is much higher than our cameras utilize?

Davin,


This will be for recording and playback if necessary.


The customer came to us with the 2.8Gbps request. I am not sure of where they came up with that number. Our techs here said they had never heard of any wireless camera system utilizing that bandwidth and you just confirmed that for me.
