    running client software is one thing, actually using it for play back, with or without audio, is another thing.

     

     

    commercially I wouldn't push it as a solution where the DVR/NVR resides in the same building (Obvious reasons). If a customer wants to remotely view from home, they most likely already have laptops/iPads.

     

    your higher end clients who are tech savvy and rather view from their sofa. (I've found that once you install for an office environment it's only a matter of time you find yourself at someones residence) They have no problem running cat 5/6 and understand the flexibility offered by having it done that way. This way also generates more income, as well as future work from their friends and colleagues.

    I'd also add, your DVR IP address should be static.

     

    Some people use more than one router at home (For whatever reason), even if both are set as DHCP.

     

    Main router, usually provided by ISP, 192.168.1.1, Subnet 255.255.255.0. an IP range of 192.168.1.100-149

     

    Second router with static internet setting of 192.168.1.2, Gateway 192.168.1.1 & Subnet & DNS same as main router.

     

    Lets say second router set as DHCP, issues an IP range of 192.168.10.100 - 149

     

    Know lets assume your DVR connects to 192.168.10.101.

     

    From main router you'll need to forward needed ports to IP address of second router first, than forward ports from second router to IP address (192.168.10.101) of DVR.

    My DVR is setup with proper DDNS and port forwarding using "ISP A", this is working fine for viewing the cams on LAN and also remotely using "ISP B". I can access my cams using browser and also through iPhone App's without ay problem.

     

    Accessing DVR via web browser from ISP B, (Personal Hotspot from iPhone?) or any other outside ISP, it's using ports 443- HTTPS or port 85- HTTP if DDNS is setup properly.

     

    Locally connected (Same router, thus same IP range as DVR ) iPhone app uses RTSP port 554 without issue. It's only an issue when coming in outside your LAN. Forward port 18004 to DVR IP address and test using 3G network.

     

     

    Where do I change the RTSP port?

    Without knowing Mfg/Model of your DVR....how should I know? Check the owners manual.

     

    Android base phones, combined with their data providers, it's been documented (Look around Google), some don't play nice with rtsp port 554. Solution has been to change it to 5554.

    Since you've built computers, you know heat kills.

     

    I'd guess the build dates are all pretty close with each other (That means they'll fail the same time). You said they're old too?

     

    I'd start by cleaning them of dust and replace thermal paste.

     

    Forensically go through event viewer, compare all software updates.

     

    Using a multimeter, I would test & document everything. Also known working locations.

    Im a PC guy myself too, some say a geek...

     

    I've built my own HTPC's (DVR's) and use Silicondust's prime for DLNA TV viewing, works awesome.

     

     

    When it came to security cameras i wanted simplicity, thats why I went with Swann NVR series. They also support NAS storage if needed. Installations a breeze since they're POE.

    It's just not video ports, some rural ISP's also block VoIP ports too.

     

    Use tools like http://canyouseeme.org/ to see whats open or closed.

     

     

    You can also use this http://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers for an understanding of witch ports are used.

     

    In some cases (non proprietary) using a PC as an gateway to spoof blocked ports works. If you're lucky, some boxes, using an edit tool, reassign what ports it listens on.

     

    Separate from above,

    Gets even more complicated if trying to view from an iphone. An understanding of UNIX helps. READ THIS http://content.hccfl.edu/pollock/AUnix1/FilePermissions.htm First Jailbreak it, than log into ROOT

     

    In order to access ROOT directory to reassign ports you'll need a jailbroke phone.

    Post subject: Remote access via O2 USB modem. Reply with quote

    Hi, I have been asked to set up a cctv system in a farm yard without a hard wired internet connection. I have it set up on the bench and can access the images via my local wifi network but I can't get access via the USB modem.

    Do I need to change the IP address of the USB modem? And if so how do I go about this.

    Any advice would be greatly appreciated.

     

    Check with SIM card carrier, they might be blocking some ports? Could also be a firewall issue with OS. What speed? 3g/4g/lte?

     

    Why not use SIM modem connected to DVR than DDNS?

    Hello,

     

    i have my DVR connected to the internet. rtsp-Port: 554, MobilePort: 3599, MediaPort: 34567.

    On my PC i get the best quality with CMS software via port 34567. It does not make any difference in speed/quality wheter i use the ip or use my DynDNS domain. No issues at all.

    Now i wanted to use VLC instead of the CMS software.

     

    If i use the IP with:

    rtsp://12.345.678.9:554/user=login&password=pass&channel=1&stream=0.sdp?

    everything works fine. The speed/quality is nearly the same like with the CMS software.

     

    but if i use the DynDNS domain like:

    rtsp://my.dyndns.domain:554/user=login&password=pass&channel=1&stream=0.sdp?

    It takes ages to connect and if it get connected the quality is much worse

     

    Any idea what might cause the problem?

     

    try doing tracerout on DDNS, my guess it's a slow boat to China.

    Hi

    The story so far......

    Have tried to connect camera to the dcr using baluns with power tails and cat5.

    Didn't work so tried a bnc cable and worked straight away.

    I obviously want to use cat5 for ease of running cables and cost etc.

    The cat5 cable i used was a working network cable.

    My question is do i use a normal network cat5 cable or does it need wiring differently....or maybe the baluns are faulty.

     

    Could be a faulty balun, or wrong type for your use.

     

     

    Make sure that network cable is strait thru and not crossed, 1 to 1 vs. 1 to 8.

     

    Typically network/Ethernet cable is strait thru, it's paired pins 1,2,3 & 6 (1&2 - w/orange, orange/w) 3&6 - w/green, green/w) (568 A/B). Difference between A & B, orange pair are swapped with green pair.

     

    For you AT&T Merlin fans, yes, B was originally 258A

    I also use the Swann-8-Channel-3MP-NVR-Security-System-with-2TB-HDD-and-4 (Now -1080p-Cameras.

     

    Really happy with it!!!

     

    Fun little feature it has (not sure if other NVR's have this) the ability to play a .WAV file. Since our front door is inside a courtyard separated by an 8 foot gate, the audio out from the NVR plugs into an inline A/B auto switch that connects to master bedroom/bathroom in ceiling Polk speakers.
