Looking for suggestions..


Hey all!

I've ran into a snag that's outside of the scope of this forum (It has nothing to do with Linux or anything else GNU), but the folks I've ran into on here have an incredibly diverse pool of knowledge, so I figured I would ask anyway.

Does anybody know of a good place to go to cuss, discuss and learn about things DVR? A friend of mine bought one and we've on and off for a year been trying to get the app on his phone to connect to it. I just spent a day going over everything in his office from the staples in the carpet to the firewall in his modem/router combo. The only stone left un-turned I guess is to take a stool sample from his dog and send it to NASA to test for extraterrestrial interference. I'm at a complete loss..

Anyways, thank you guys/gals if you have any suggestions! (Also, machine translators have came a long way, so even if the sites you know of are in Russian or another language, I'll make due! )

You left out a few "minor" details.

Posting the make/model of the DVR might be a good start. All things DVR depends on that particular model and its features. Hopefully there is an online manual...

What is this app? What is the app supposed to do?

I assume the DVR connects to the network either by wireless or wire. Does that at least work?

Thanks to all for the suggestions! I'm following them as soon as I tab away from this thread.

My apologies, I didn't know enough to know that those details where relevant. Details are as follows:

The model of the DVR is sde-4001n (made by Samsung). There is an online manual, and it suggests the following app -

iPolis. The app is supposed to allow you to view the live feed from the cameras and watch playback of previous recordings. I've discerned that you can simply use the internal ip of the DVR unit to do these things as long as you're connected to the same router. That works great. To do these things remotely, the only option is a DDNS service. The current snag (as far as I know) is that there are only a few DDNS services available for this particular DVR model to interface with. Since it's old, some of those services have gone tits up. changeip.com was listed though and it has live services. I'm trying out the free DDNS now before I shell out my or my friend's cash though to make sure it works. Otherwise, like many other endeavors, we're going to be robbed of a ton of cash for a non working service. Recently, I signed up for an IT company's services in a fit of desperation to get a Windows Server to bend to my will. They where completely incompetent in every way except extortion. Long story short I had to close down my bank account and open another one to keep them from zeroing my account the instant I put a penny in it.

I say they're incompetent, yet I as well am. But, alas, as most situations I find myself in - there's simply no other option. Either funds are not available, or even when backed by an infinite amount of money, there exists no technician on the planet who both knows what he's doing and likes money.

Anyways.. My bchin' aside.. The DVR connects to the network via wire. I have gotten iPolis to connect successfully via internal ip (no DDNS) without too much trouble. So I know that the DVR is at least broadcasting something.

The manual for the app is here: http://www.samsungcc.com.au/sites/de...le_android.pdf
And for the DVR is here: https://www.manualslib.com/manual/76...-Sde-4001.html

The original CD with that cool little program "Quick Connect" for the PC before it was transmuted via alchemy into a mobile only app that has nothing to do with DVRs has been lost to the winds, naturally.

Also, an assumption that I've been making that may not be correct is - that "RTSP" is a generic port number to simply follow an IP address. I.e. when I forward all the ports required by the DVR, I simply forward the suggested ports 4520-4524 to the internal ip unceremoniously and put the default one at the end (4524) into the RTSP box inside iPolis.

THANK YOU GUYS/GALS SO MUCH!! The members of this forum have been sharing their experience and expertise with me for years and I want to be certain that every one of you know just how thankful I am for that. I've never forgotten my place in the world (a know-not) and have likewise never lost perspective on just how lucky I am that this forum exists.

UPDATE!!

So I figured it out with you guy's help.

iPolis will work when connected to the internal router the DVR is on. However, to view the cameras anywhere else, you have to have a DDNS. Well, I discovered a work around of sorts that I will describe here in case some other person such as me searches and finds this thread.

I used Swann's ddns service. I don't think that it's really taking advantage since this guy has four such system and three of them are Swann, only one is Samsung. I registered another address on swanndvr.net and then forwarded all the ports just the same on the router and then plugged 80 into the HTTP port and 4524 into the RTSP port. Still no idea exactly what the difference is.. But that worked. I walked a block away just to make sure and it connected. Oddly.. It looses the connection and will not reconnect (DDNS does not work) as soon as I come back and the phone reconnects to the wifi.. Odd, uh?

With a similar DVR system I setup you could register with the manufacture and user their DDNS or use your own FQDN which I already had via a dydns service. Forwarded the ports in the firewall and it worked as expected.

With many IoT devices like thermostats and cameras the manufacture creates something similar to a reverse ssh connection with a remote server. The device connects to the manufactures server when registered and then the app connects to their servers. Their servers basically connect the data stream from your device to the app running on your smart device.

The unfortunate caveat with many of these devices like door locks and security systems is that without internet service your basically SOL. You can not open your door or turn off the alarms from your phone.
