I have an old Q-See QSD2316L used to work for remote viewing and had stopped working , most likely after OS or IE upgrade .
Following msg when accessing local intranet or ourside the router.
The mobile phone was detected based on Symbian S60 2nd.
We recommend that you download this SCam_2nd.SIS ver1.1.2.624 to install.
Had tried changing the router , enabled every Active-x setting in IE and had givenup on it.
Decided to get it working this weekend and had spent 3 to 4 hours and finally go the correct software to install and configure . posting so it may help some one else tinkering with this problem.
1. Updated the QSD2316L Firmware -- ( May not be necessary )
http://qsee.custhelp.com/app/answers/detail/a_id/521/~/qsd2316l%3A-firmware-version-2.7.1-(myq-see-and-smartphone-support,-latest)
Just copied the tar file to a flash drive and followed the short instructions . Did nto have to untar the file in the flash drive .

Note that the DVR server port number changed after the firmware upgrade from default 2000 to 1160 . So if you have a pinhole opened for the 2000 change port at the DVR or at the router to match
2. Downloaded the CMS software from Q-See
I used the following CMS software
https://qsee.custhelp.com/app/answers/detail/a_id/915
and following the instruction to install and configure my DVR
https://q-see.s3.amazonaws.com/content/files/RightNow/T-How%20to%20Add%20Devices%20into%20CMS.pdf
Works good now as standAlone client .. hoatname + port 2000 or what ever is configured on you DVR
Note that there will is http port 80 and server port 2000 .. use the server port
they may be later versions of the CMS software check here
