Implementing Video Security via IP as part of your School Safety Program Mark Knaack Technology Director Branch-ISD

Outline for the Session Define types of systems Advantages/shortcoming of Video Technical Issues Policy Issues Q&A

Legacy vs. Hybrid vs. IP Legacy Systems Dedicated Coax Wiring VCR’s and lots of Tapes Limited Search/Intelligence Capability Typically Centrally Controlled and Monitored

Hybrid Systems Analog Cameras Record to DVR DVR can be remotely monitored via IP

IP Systems Use existing Infrastructure* File Server or DVR Storage Can be centrally and remote monitored

Advantages of IP Video Uses Cat 5 wiring and Ethernet, technology that schools are comfortable with Autopilot – no tapes to change/archive No image degrading due to old tapes Intelligent Video – Searches, scans etc

Shortcomings of Video Typically it is a reactive technology PTZ cameras only see what they are looking at Lighting is important, but you can see in the dark if you plan for it

Technical Issues Network Issues Plan for a lot of traffic - VLAN or use a Separate segment if needed Cheaper Cameras tear up bandwidth, testing is critical Power Over Ethernet – Cost, wattage and compatibility issues

Lighting issues Night time, Backlighting, Reflections

Cameras Still, Zoom & Pan Tilt Zoom

Day Vs Day/Night Not all Cameras can do night Total Darkness

Software Compatibility Make sure the Camera you plan to use is supported by your software! PTZ gets tricky, just because the camera can do it doesn’t mean the software will support it. (Ask me how I know this?)

Frame Rates 30 Fps= Best of Breed (Casino Quality) Motion pictures only use 24 Fps 5 Fps = Standard Quality (Retail) 1 Fps = Space Saver (Parking Lots etc)

30 Frames/Second

4 Frames/Second

1 Frame/Second

Resolution Common Intermediate Format (CIF) 1 CIF image is common in Analog systems 4 CIF is the IP standard Many cameras must give up FPS to gain Resolution – Be Aware!

Video Format MPEG-4 = Most efficient Only transmits changes in the scene Can lose a little detail Licensed Technology You may need a licensed viewer to use MPEG-4 M-JPEG = Better Image Quality Transmits the entire image, every time Uses up to 4 times the bandwidth and drive space as MPEG-4 Be sure what your software supports

Server Considerations Disk access speed is critical on recording drive (SCSI) Archive drive speed less critical (SATA) CPU and Memory will vary by software You can do more cameras if the frame rate and picture size is reduced, it all comes down to resources

Policy Issues Document Retention Policy 30 Days for Video Eavesdropping Audio in public spaces is not permitted Audio in classroom may be permitted Privacy Concerns We require two administrators to review video Board Policy Make sure your School Board is on board. Sell this as part of your school safety plan, otherwise thought of big brother will come up.

Planning a System What do you want to cover Mark hotspots on a map Do a site survey with cameras so everyone knows what they are getting

#1 Back hall with 211

#2 Back Hall with 212

#3 Back hall Flat with 212

Back Hall Area Pick One

Installation Self Install Can be done but is time consuming Vendor Install Look at many and check references Decide what bells and whistles are actually going to be used

User Policies Who needs access Guard station Principal Liaison Officer (PDA) Local Police Clerical Staff

Plan for Disaster Multiple viewing locations Training for key personnel Tamper Resistant Cameras /alarm you if they are moved or blocked
