    To what kind of use is this LPR camera coming to? 40-50ft seems a bit long distance for normal LPR usage (LPR for gate control etc.).

     

    If possible, installing the camera closer would probably make the system way cheaper than it is with 40-50ft, i wouldnt personally install LPR camera more than ~15ft away from the plate in case of gate control or such.

    Where do you see this green screen? Browser? Some NVR/VMS software?

    When do you see it, when the camera is moved? When there is movement on the camera? On "still" image? Totally random?

    What kind of setup do you have? I've seen this kind of problem appear when there is too much traffic and not enough bandwidth in the network to handle the cameras.

     

    I've also come across cameras with loose connetors causing this, so Kawboy12R's tricks might work just fine.

    Could you tell us the nvr manufacturer, camera manufacturer and model, it is easier to try to figure out how the setup goes with a bit more details.

     

    Some manufacturers have a automatic config for their own cameras and nvr, but on many cases you have to either find out the ip that dhcp gave for the camera, or set the ip manually.

    After you have the ip(s) for the cameras, you might have to set the ip(s) to your nvr manually.

    - Can add a large number of camera's (more than 256) it monitors

    == Enterprise supports 128 channels or 256Mbps of bandwidth which ever comes first per server.

    Obviously you couldn't add say 128 2Mbps cameras as it would be to much bandwidth.. What type of cameras

    are you talking about.

     

    Why is 128 x 2Mbps (= 256Mbps?) too much bandwidth if they support 256Mbps or 128 cameras?

    I just ripped out an analog system in a warehouse in NJ. The cameras were all effio 700 TVL eyeball cameras well focused and placed. He had an 8 channel DVR and a 4 channel DVR for 12 cameras. They were both speco dvr's. The reason he upgraded was because I did his house in NY with IP and he was

    absolutely amazed. The guy had the money to upgrade to IP even though he had a perfectly fine analog system. I guess lucky for me, cause that

    meant two IP jobs within 2 weeks, lol.

     

    What a lucky fella

    What a funny thread to read!

     

    Doing technical support in surveillance system has taught me that no matter whats the system, there are issues. Granted, less on the analogs than on IP, but thats because all the new installs are IP, and if old analog has problems, nobody bothers spending money on troubleshooting and buys a new IP-system instead.

     

    Mostly problems on IP are caused by cheap systems or systems that are built on an existing network that handles other devices aswell, or just someone installing who is inexperienced with IP-system.

     

    For me, if i was to install a new system, it would definately be IP system with server-grade hardware and a VMS. I might consider analog for a system that only has PTZ-cameras and does not require as high image quality, because analog RS-485 PTZ still works better than any network PTZ.

    Your computer ip-address must be set to same network as the devices you're trying to connect to, either by ip or netmask.

    Few examples:

    - Your computer ip is 192.168.1.5, netmask 255.255.255.0, you can connect to any device with ip-address on a range of 192.168.1.1-254.

    - NVR ip: 10.140.1.150 netmask 255.255.255.0, any ip camera from 10.140.1.1 to 10.140.1.254 is possible to connect to this NVR.

    - Router ip is 192.168.1.1 netmask 255.255.255.0 and DHCP is enabled. Router will provide ip addresses to all the devices connected if the "automatic ip /ip from dhcp" is enabled, and you can check the addresses assigned to devices from router.

     

    PoE switch only works just as normal switch, but supplies power via ethernetcable. Ip-settings are just the same.

     

    Just like ssnapier said, there are "camera finders" or "device search" or "ip address utilities" for most of the camera manufacturers. To name few i've used:

    - Dahua ConfigTool

    - Dynacolor DeviceSearch

    - Panasonic EasyIpSetup

    - Pelco Device Utility

    - Shany MyFinder

    - Sony IP Setup or SNC Toolbox

    - Axis IP Util

    - Many more..

     

    Default ip addresses for cameras can usually be found out via google. Just google up camera model and "default ip".

    Could you give us more specific details on your current setup and cpu/mem/network usages (Task Manager/Resource Manager on Windows)? With those, it's probably rather easy to calculate what the requirements are.

     

    Also what's the software you're using, does it record all the time, does it have motion detection built-in or are you using the motion detection on cameras? You say 3mp cameras, what bitrate you use on those?

    You should check how your router actually acts though, i've come across some cases where 2 computer in same router actually connected from Computer -> Router -> Outside router -> Back inside router -> Another computer.

    So make sure your LAN is actually configured properly. Probably the best choice is to buy a 1Gbps switch for the cameras, since normal cheap routers (ones that usually ship with the connection from isp) are bad at handling lots of LAN connections at high speeds.

    What first caught my eye was the same port for mobile and secure http, you should try a different port as they're supposed to be different services.

     

    The different version "fix" doesn't sound right either, but if it works, who cares right? You could still troubleshoot it a bit:

     

    Did you check the port forwarding and firewalling?

    It's always wiser to use IP-addresses than DNS-names, or if you must use DNS, configure your hosts-file to manage with them.

     

    I dont have any experience with Milestone, so i can only try to help on general networking issues though.

    You might also want to check that your ISP doesnt restrict the usage of the ports you're trying to use.

     

    For example, might be worth a try to go with a setup where you connect to external_ip:10000 - :10002, than :81 - :83

     

    external_ip:10000 -forwards-to-> cam_ip:80

    external_ip:10001 -forwards-to-> cam_ip:554

    external_ip:10002 -forwards-to-> cam_ip:8557

     

    Or what ever are the ports you use/need. This ofcourse requires your router to support "from port" "to port" configuration. For easier troubleshooting, you should first forward the ports to your pc, then run canyouseemee.org.
