  1. Now this is documented someone else may be relieved of the frustration of making the same error (me included)

     

    The lesson here is that changing routers will very often change both deafu7lt Gateway and DHCP range so if you have to change router especially to a different brand name, be aware of the IP range and Gateway address. Less so among routers of the same brand though.


  2. you need to set your port forwarding to 192.168.0.88 its forwarding to the wrong IP address, make sure you have static ip to for your router and the dvr or it will not work every time it changes

     

    device ID 88 is OK also, so long as you remember to set the DVR to static and reserve the IP in the router's DHCP address reservation so that it always gets that IP (and no other device gets it) in the event there is a power out or the device is restarted. This is VERY easy to do in the VM router under advanced settings under the DHCP menu choose IP or Address reservations. Don't forget to Apply

     

    Virgin Media Superhub is one of the Easiest routers to set port forwarding but there is often a delay of a day or so before the ports will report as open ( Haven't found out why, but recently thats been the case with every VM SH that I set up)

     

    Don't lose sleep over this it will come right eventually.


  3. I usually find that 1MBPS upstream will comfortably support

    4 cameras, at sub stream speed producing fluid motion with minimal latency

     

    I would agree that your estimate is as close as you can get without actually field testing.

    i.e you see moving pictures without too much jerkyness and not too much delay


  4. Video out port is a legacy port from the older designs. Most of the HD and IP systems being produced now have no real use for a Video out RCA or BNC (composit) port

     

    "My DVR doesn't have...."

     

    Ah then you need a VGA to video adaptor convertor. A bit unusual these days I have a cabinet full that I bought in error.

    they should run you about £5- £10 and this will connect to your modulator.

    As was stated [i"]you could run a HDMI" convertor[/i] but as has already been said they "are more expensive" and I would add thereis no 'quality' benefit.


  5. Hi... I have a swann dvr8-3425 with hdmi and vga outputs. I have a rf modulator but I can't find the correct cable or device that I need to send the video from either the hdmi or vga from the dvr to the input of the rf modulator. I purchase a hdmi to rca cable on Amazon but nothing in being transmitted. Not sure if I have the right cable. Is there any easier method to transfer the video to all the tv in the house?

     

    Thanks

     

    No you should be using the Video Out port from the back of your DVR using a RG58 lead BNC to BNC and using 2 x BNC to RCA adaptors to connect to the modulator VGA and HDMI won't connect to your modulator.

  6. Try setting up the DDNS hostname in the cable router rather than just in the DVR. Ifr hat is what is happening.

    Why do y0u mention the routers of the remote sites that will receive the CCTV? They do NOT requie any DDNS settings only the one at the DVRs Network will require a DDNS setting up.

     

    When you say the first house goes down, what set up was done? When you set up a remote client software you substitute the network's public IP with your DDNS hostname in the address field that you set up in the DVR's network services menu, you do NOT need to setup the DDNS in the remote site's router and that is what it sounds like you've done because if the DDNS sever id being updated correctly, referencing the hostname instead of the public IP will work, but if the DDNS is being updated at another location then of course it's not going to locate the DVR

     

    For Clarity the site that has the DVR we'll call the local site and the sites from which you are viewing we'll call the remote sites.

     

    Only the Local site requires DDNS setting up to update the DDNS server. The only r5eference to the DDNS anywhere else id that you substitute the local site's public IP with the hotsname in the settings of the client software.

     

    What you are describing it sounds like someone that has no idea has set up an update client for that DDNS account on the remote sites which would be ridiculous.


  7. CNM are no longer in business and despite several of their staff still being prominent on the CCTV scene, there just aren't any firmware downloads available ( been there, done that, got the T-shirt) so unless someone has these archived FORGET THAT. Dump it in the nearest skip and buy a replacement.

     

    From this guys perspective, I recommend that even if you don't need it now, download a firmware update just in case this happens to you later. You'd have to be very unlucky for it to happen again but who knows.

     

    I placed an order with CNM and within an hour of placing my order it transpires, that the receivers marched in and took over their office and literally threw the guys out onto the street. Undeservedly I am sure.


  8. The camera dip switched are usually related to the Camera's address and the Baud rate. I suggest you email Eneo for the instruction sheet and this will tell you the dip switched. Since each controlled can control a number of cameras, each camera has an

    address 1, 2, 3....99 etc. this allows the controller to CALL the specific camera to respond. Then each camera can be programmed from the controller. The baud rate that's commonly used in a typical PTZ setup is 4800BPS or 9600BPS. This has to match the controller or the keyboard settings or both. That's almost everything but there may be a couple other settings that need to be configured according to your control device.


  9. In your Router advanced settings reserve the IP address and that DVR will only be allocated the same address.

     

    You may find other ports to open if you look under Netservice settings, you may see the Mobile Monitor Port and the RTSP port (always worth opening). Look for the Media Port in the

     

    Worth noting, Virgin Media ports sometimes won't report as open until the next day (don't ask me why) this has happened to me a few times.

     

    Opening port 9101 seems okay but also open port 80 and you should set up the DDNS either in your router of DVR, despite the public IP address having a long lease time, the chances are it will change when you are away from home. Virgin Media public IPs change typically twice a year but make no mistake they are dynamic


  10. Some form of Solar charger and li-ion batteries may be the answer to the power issue, although how to get your signal off the island onto a DVR or NVR on the mainland is a slightly more difficult problem. I suppose you could do line of sight radio transmission and again power using solar power and batteries. There are now some very good wi fi link equipment on the market with unbelievable ranges which might be worth investigating.

     

    Does seem a rather expensive project just to spy on a few dumb birds. Unless this is a research project that is funded you'll have to be very dedicated and committed to this project to fund it as it's not going to be cheap.


  11. As a precaution against IP conflicts, at the DHCP settings you could reserve the DVR's IP address effectively removing it from the DHCP pool and avoiding potential IP conflicts. I just checked the details of your router on portforward.com and although it's exact model is not listed there is a model with the suffix R which appears about the same and port forwarding on that seems very straightforward.

    Assuming you opened the correct ports it may be that the DVR is still not visible from outside the LAN because the ports are blocked or the DVR is not communicating with the Router. I know from bitter experience to go back and check every detail again as sometimes there will be a tiny error we didn't see. Tedious I know but essential that everything is correct, Computers and DVRs don't understand nearly correct...

     

    Another site that (I like) you might like for checking open ports is yougetsignal


  12. Would you have a instruction manual showing a 'screenshot' of the CMS software your DVR requires?

     

    It may be that you won't need a CMS if your DVR has a web interface. Try typing in your DVR's LAN address

    into Internet Explorer and see if you can access it that way, as without the correct software you may be chasing your tail a long time.
