  4. Outline • IP Networks • Network Cables • Network Addressing • Network Routing • Network Troubleshooting • VideoWatch by Datawatch • IP Cameras • VW DVRs/NVRs • VW Standalone Cameras • IP Camera Troubleshooting

  5. IP Cameras – DW Procedures

  6. Pre-Configure • At this point, Camera Systems to be pre-configured at DW central before they are brought to field • If everything runs smoothly, tech will only have to plug components in to network to have functioning system. • Internet connectivity may have to be configured on site.

  7. DW Support Structure • Tier 1 – Field Technician to establish IP connection to allow DW to dial in • Tier 2 – Designated Central Personnel (currently Dan Summers, subject to change) • Tier 3 – Designated Video Engineer (currently Dan Summers)

  8. IP Network Cabling

  9. CAT5 Cable • CAT5e is plenum grade Unshielded Twisted Pair (4 pair) • Networks send up to 100,000,000 bits per second over each cable • The twisted pairs shield the signal from interference • No kinks or splices in wire, maximum of 100 meters (300 ft)

  10. CAT 5e cable & RJ-45 Connector

  11. CAT6 Cable • CAT6 is similar to CAT5e, with better/heavier insulation on cable and individual wires • Supports speeds 10X faster than traditional CAT5 (1GBPS rather than 100MBPS) • Also used in situations of high electronic interference

  12. RJ-45 Connector Pin-Out

  13. Network Tools • Crimpers • Cable Tester

  14. Video of Ethernet connection • http://www.livescience.com/common/media/video/player.php?videoRef=ethernetcable

  15. IP Network Components

  16. Network Devices

  17. Routers • Devices that control IP traffic between different networks • Routers control IP access into/out of network • Routers provide high level functions for network, including DHCP and gateway

  18. Router Diagram Internet WAN IP: 173.10.130.249 LAN IP: 192.168.0.1 LAN 192.168.0.3 LAN 192.168.0.21 LAN 192.168.0.22 LAN 192.168.0.23

  19. Switches / Hubs / Bridges • Switch is device that connects IP devices together in same network, and controls some traffic flow • Hub is a device that connects IP devices together, with no traffic control • Bridge connects two different network mediums together (ie DSL line and Ethernet cable, or Cable Modem and Ethernet)

  20. Network Interface Cards (NICs) • NICs are the ports that the network cable plug into on the device • Usually LED will be lit to indicate network connectivity • Some devices are Powered over Ethernet (PoE). Power is delivered over the network cable to the device

  21. IP Network Addressing

  22. MAC Addresses • Media Access Control Address • Every network device in the world has unique MAC address • Routers & Switches send traffic to their local devices via MAC address, not IP • MAC addresses not routable between networks, need TCP/IP to do this

  23. MAC Address example

  24. IP Addresses • IP Addresses are the configured address of a device • Each IP address has to be unique – no duplicates on the network or anywhere in the world • Think of it like sending physical mail – every address is unique • Example - 192.168.0.2

  25. IP Address Example

  26. IP Addresses on Network • On a single network, the network addresses will be very similar to each other – each router is only able to work with its own network’s traffic

  27. Private IP Addresses • Because the # of IP addresses was going to be used up, a convention was invented to make certain IP addresses “Private” • Routers will not send traffic with/from these specific IP ranges out from their local network • Private Ranges: • 10.0.XX.XX • 172.16.XX.XX • 192.168.XX.XX

  28. Private IP Addresses to Internet • These private IP addresses are what most LANs use. • For these devices to get Internet Access, their router will translate the private address into a (public) IP address, one that can be routed over the internet • When the router receives the data from the internet, it translates it back to the private IP address, and sends it to the local computer • This process is called NAT (Network Address Translation)

  29. Network Address Translation(NAT) • NAT is the process that a router will “re-address” traffic from one IP to another so that multiple computers can share one public IP address to receive internet traffic • Note that NAT is done inside of the router – the computers do not know that it is happening. • NAT allows internal computers to share one public IP address for internet traffic (outbound traffic only)

  30. NAT Routing

  31. Public IP Addresses • Public IPs are controlled by an international organization who will regulate IPs as needed. • Internet Service Providers, like Verizon and Comcast, get a large range of IPS, and they lease them out to Datawatch and our clients.

  32. Subnet Mask • EASY - Just Type in provided subnet mask • Each IP address contains two parts – the network number and the device number • 192.168.0.21 – unable to know what part is the network ID, and what part is the Device ID • Subnet Mask is how the router and machine knows where to split it • Subnet Mask of 255.255.255.0 tells the device that its network ID is 192.168.0, and its device ID is .21 • Good Rule of Thumb for DW: • FOR DW NETWORKS(NVRS), will use 255.255.255.0 for IP NVR systems • ISP or cutomer network may give us a different subnet mask for public IP – use the provided mask in the device/router

  33. Subnet Mask Example

  34. Default Gateway • EASY - Just Type in provided default gateway (will be router ip address) • Each device will prompt for a default gateway • This default gateway is IP address that all traffic will be sent to • It is the LAN address of the router

  35. Domain Name Service (DNS) • DNS is the system that translates a computer name to an IP address • www.google.com needs to be translated into an IP address to send data to it • Internet servers (DNS servers) are responsible for figuring out the IP address of these names • DNS is required for any internet browsing, since it resolves the names to IP addresses

  36. DHCP • Instead of having to type in the IP address for each device(could be 100’s on a network), DHCP is a network service that automatically assigns a temporary IP to devices as they start up • It “leases” the IP to the device for a period of time (i.e. 1 day) • When the lease expires, the device will renew its lease

  37. DHCP – IP Cameras • On IP camera systems, it will not work to have the cameras or NVR using DHCP – these devices should be set to a fixed IP • Otherwise, the NVR will not know the IP address of the camera (since it changes), and will not be able to record it • DHCP should still be enabled on the router, so that when a tech plugs their laptop in, they do not have to manually change their IP address

  38. Static or One-to-One NAT • Static or One-to-One NAT is the configuration that allows Datawatch Central to dial into a device that is on a private IP address • Regular NAT allows access from LAN out, but does not allow the internet to dial in directly – Static NAT does • Configure the router to take unsolicited outside traffic, and redirect it to a designated internal IP address

  39. Static NAT or One-to-One NAT Connection Request to 173.10.130.251 With these three standalone cameras, this configuration would require four static public IPs – three for the cameras, one for the router Router redirects traffic for 173.10.130.251 to private IP 192.168.0.21 Private IP 192.168.0.21 Private IP 192.168.0.22 Private IP 192.168.0.23

  40. Static NAT or One-to-One NAT Connection Request to 173.10.130.251 With these three cameras and one NVR, this configuration would require two static public IPs – one for the NVR, one for the router Router redirects traffic for 173.10.130.251 to private IP 192.168.0.21 Private IP 192.168.0.24 Private IP 192.168.0.21 Private IP 192.168.0.22 Private IP 192.168.0.23

  41. IP Network Architecture

  42. LAN/WAN/INTERNET • Local Area Network – this is a single network, typically setup with private IP addresses • Wide Area Network – this is a collection of networks that are connected to each other. • The Internet is a WAN

  48. IP Network Routing

  49. Network Routing • Routers have two sides that they receive traffic on – the internal or LAN side, and the external or WAN side • Routers determine what to do with each IP packet – forward it on, or ignore it • Routers may be configured to forward requests from LAN to WAN, but deny access from WAN to LAN

  50. Router Config • Setup Time/Date • Setup WAN connection • Setup LAN connection • Setup DHCP for LAN • Setup Router’s Routing Permissions if needed • Setup Static NAT
