I recently purchased the DNR-202L with two DCS-934L cameras to upgrade my home security system. The installation of the cameras went pretty smoothly although they would not work with my 802.11ac/n/g/b WIFI network. No problems here as I was able to activate a secondary wifi for 802.11n/g with very little effort on my router. Additionally, I had to download the latest version of Java to enable viewing the cameras video from Safari. The challenges appeared when I started to install the DNR-202L.
My Mac is the iMac with the Yosemite OS. The DNR-202L is HW version A and Firmware version 1.01. The problems started when I attempted to download the setup wizard. The D-Link support site for the DNR-202L points you to the wizard version 2.02 which after a little work I determined was for the newer firmware. When I ran the wizard it would fail and I'd get the error to eject the disk (Apple's way of aborting a failed app start up). After several attempts I followed the link used to download the wizard .dmg file to the D-Link FTP site. Once I ftp'd to the site as a guest I was able to find the wizard for the 1.01 version of firmware and downloaded it. I was able to run the wizard and get my DNR-202L up, registered with mydlink and running. But, it would not auto-detect the two cameras on the network. (Note: Not sure if anyone else with a Mac has experienced the setup wizard problems, but it's not related to the DNR-202L firmware at all. Appears to be a bug in the wizard.) After a little thinking I attempted to login to the DNR-202L via the IP address and was successful. I was able to add the cameras from the web interface with no issues. I downloaded the IOS MyDlink NDR app to my phone and voila it worked. I still can't view video using Safari (I think its version is 9.X), but that seems to be a known issue per the web.
My explanation makes this sound pretty simple, but it took me several hours to complete. I would also point out that I have over 35 years experience in computing and networking. The average Joe or Sally buying these things from Best Buy, Amazon or some other place would not have been able to figure things out (in my opinion). On and it was Christmas, so the Technical Support center was closed (I attempted to called to let them know I was going on to the FTP site and got the "We are closed..." recording).
Now I'm faced with a decision. I'm on an older version of firmware. As I stated above the wizard is for the newer 2.02 firmware. I have downloaded the .bin file (found it on the FTP server), but I don't think I want to go through the aggravation again. As usual, or as I have found, little support goes to the Apple related Mac software and that's probably why the wizard hasn't been fixed. I also find it frustrating that when running the 1.01 wizard it does not prompt you to download the latest firmware like the camera wizard did when installing them.
If anyone would like any further detailed explanation on how I did this let me know. I'd be glad to help.
