i would just like to put this out there-- there is an app called RDM+ that you can install on your iphone for $9.99 and then you must download free software to the computer where the feed from your DVR is on at all times. http;//www.rdmplus.com/rdm/iphone download.html and you can see your security cameras. I have been using this for a week and it works great. It took less than 10 minutes to set up.
