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.

That stick is useless..... Chromecast is still better. Look into raspberry pi 2 model b for open source stuff. Myself, I use Intel NUC i5 running windows mounted behind TV's (SwannNVR/Swannview+)

I was able to load Swann View + on WYSE c90le thin client running embedded XP. Works ok.....Did it just outta curiosity.

are you talking about the 9pin port on back? RS232/RS485 Data sheet says for 485, 9600, 8, 1, none 9600 bps dome speed.

you probably just overlooked something.... recheck ports and confirm you clicked save.

How are you getting power to the wifi cams? If powering them isn't an issue, I assume you've given some thought about placement of AP and it's power/data needs.

Seems a lot of the people here have busy jobs. (I'm retired) Be patient. Describe how you've configured your router/s, DVR and what ports you've opened and why. Sounds like you successively setup DDNS HTTP/HTTPS using an outside network web browser.

Keep forwarding 18004, and put rtsp back to 554.

Install a port scanner on your iPhone and confirm they're not blocking. you can also via Mac goto http://www.canyouseeme.org/

Just so others (including myself) are not confused. What Tomcctv posted wasn't a typo. RSTP (Rapid Spanning Tree Protocol) Referring to possible Loop error. & RTSP (Real Time Streaming Protocol)

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.

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. 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.

The phone Android or iOS ? If your current RTSP (Real Time Streaming Protocol) port 554, change it to 5554. For iOS, forward port 18004 for router attached to DVR/NVR. Let us know how it worked please.

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.
