2 Battery Backup Systems (BBS) Early versions kept the light in RED flash vs. going dark. When LED s Introduced, BBS could keep lights in color for many hours. Most cabinets were small.

3 Uninterruptable Power Supply (UPS) Transition from line power to battery backup with minimal interruption. During normal operations these units condition the line power before going into cabinet. Surge protection should be installed between line and UPS. Stand alone units are available. These can house the electrical meter, inverter, batteries and even lighting distribution.

12 UPS and ITS Equipment Need to determine what equipment needs UPS. If the intersection has a network equipment, what happens if it goes dark? Which equipment to keep live changes as replacement equipment is installed (ie POE equipment).

13 ITS Equipment and Maintenance

14 ITS improvement installed in your community. Common components consist of the following: Fiber Optics Cameras Networking Equipment UPS Pre-Emption LED Signal heads and Street lights

16 Fiber and Mice

17 Fiber and Mice White belly mice Steel wool, stainless Brillow Pad and silicon. Have been known to eat through a door jam. Also love certain types of stranded wire insulation. Keep out of Fiber Distribution Cabinets.

18 Surge Protection Bonding and Grounding New electronics more sensitive. Older cabinets may need additional protection. Keep Ground rods visible and accessible. Ground at each structure and tie structure and equipment to the ground. Bond Structures together to equalize the potential.

19 Surge Protection Bonding and Grounding Update the Surge protection on incoming lines and equipment. Some units have alarm outputs to warn. Remember to protect the network cables on the field equipment and at the cabinet before it enters your switch. Ground the field equipment to the mastarm to prevent static buildup (PTZ Cameras).

20 Surge Protection For Cameras

21 Cameras 5 Year replacement schedule. New camera equipment may require new wiring and equipment in the cabinet typically new equipment is simpler to wire than old equipment. Video Management software may need to be updated to be compatible with new cameras. Might be able to get by with fewer cameras and get more coverage. Examples of camera technology.

35 Lessons Learned Cameras PTZ better for live viewing Fixed better for recording WDR is essential for traffic Low light cameras where no headlights Interlaced vs. Progressive Scan Fast Shutter Speeds Resolution is not everything Install after market lenses to get the most out of your fixed cameras.

36 Lessons Learned Cameras Don t Purchase solely on specs Do side by side comparisons

37 Street Lighting Replacement Schedule MH every 2 years HPS every 5 years LED Not established as needed? (7 to 10 yr) Before and after shots

38 LED Lighting Retrofit Example 80 watts vs. 150 watt Provides better lighting for cameras Street lighting already efficient, but LEDs use 50% less.

43 Switch Gear

44 Switch Gear Replacement Schedule Core Switches 6-8 years Hardened Field Switches 5 years Outdoor Hardened switches take more abuse than indoor switches. These are critical infrastructure and should be well maintained.

45 Server Maintenance

46 Server Maintenance Replacement Schedule High end servers typically have a 3 year replacement schedule. Virtual Servers - Advantages Virtual Servers - Disadvantages How much processing power SAN / Storage Arrays 5 year replacement schedule

47

48 Video Management Software Most have annual maintenance per camera ($50). This keeps you up to date with current version of software and drivers. Benefits of new software H.264 Compression Mobile Apps 32 vs 64 byte Speed of browsing.

49 Lessons Learned Organizing IP addresses of devices Example Switch M52 controller SB Camera WB Camera NB Camera EB Camera PTZ Camera Organized IP addressing scheme make changing out equipment easier.
