VMS Managing Thousands Of Cameras - Share Experiences

My bad John. Next time I will email you.

Here is some key things to look for:

• Network Setup
• How is their network setup ? Types of switches/ WAN/ Wireless used ?
• This is huge and often missed - make sure you understand what you are going to be using for network transport from edge to core
• How is security's relationship with IT ?
• This will help you understand what you need to take on vs- leveraging their IT team
• DHCP / DNS host naming is w/ pre reserveration really helps with this many cameras- IPs get out of hand quickly without a simple way to reference what is what
• Look for camera manf. that have good independent managment tools- really helps in setting up and changing settings independent of VMS if needed
• Local vs Central Storage
• Are you going to store at each location or in the local telco closet or stream to central location ?
• Remote Access
• If you are going to be managing or implmetning the system VPN access is huge with this many cameras because things will go wrong and nice to be able to troubleshoot off site when needed
• Indepdent inventory managment
• Have a good system / CRM for managing each part of system- cameras IP / MAC server info etc- this will be vital as you build out and maintain

Whether you use Milestone or another large VMS they all have their PROs & CONs- talk to as many large users as you can - it will really help you shed light on the challenges- no matter what VMS you choose a lot of the challenges will be the same- network issues, servers problems, capciity etc- these are not unique to a single VMS.

From my experience of large installations (2,000 max) one of the challenges is the number of server required. By reducing the server count the cost would be reduced- hardware, OS licenses, management , power, cooling, maintenance etc...

Some of the bottlenecks with a reduced number of servers would be the network connectivity and the storage throughput.

I can share with you below screen shots of a large school that has great infrastructure that allowed to connect all 1,721 of their Act TCM 7411s (average at 1.9Mbps) to one Dell 720xd, equipped with dual Xeon E5-2603 1.80GHz processors, 24GB of Memory running Server 2008 Enterprise connected with 10G. The attached screen shots shows network utilization at 3.65Gbps and 66% CPU utilization. The cameras are recording 50% of the video or 2Gbps via a second fiber connected Dell Compellent. The other attachment is a export from the Server Statics that detail each cameras specific resolution, FPS and bitrates (pay close attention to the Server column.)

The VMS used was Video Insght.
