when firmware 8.0 is released in the very near future it will allow you to change settings remotely and manage your cameras etc but its not an app, you will do it on your cell management page on the cuddeback website either on your phone or a computer(see GEN 2 thread on this forum for more of what it will do)
Cuddelink has a huge amount of advantages in cost and deployment options but if you want pics transmitted immediately after they are taken 1 at a time while run-in a network of multiple cameras and 1 hour at max is to long(since it would send any available on the hour and some of them may have been take 5 ,10 ,20, 30-40 minutes earlier ) then you should consider other options. Since you are a covert cell cam owner you already know you will need a plan for each camera and the cost that goes with each camera. You will also need each camera to be in a location with connected cell service.
You can run batch 1 when running a dual cell stand alone ( same as a covert ) but i still dont recommend it. The cell camera has to shut down to transmit cellularly for a few minutes to send a pic. When its shut down, it cant be receiving pics from the remotes or itself and if you have multiple cameras taking a lot of pics its very easy for a system to get backed up which would result in you not getting the pics seconds after they are taken as you wish.
Personally, i can't imagine many scenarios where getting a picture an hour at most after it was taken would change the way i hunt. Possibly if i was using it as a security camera i could justify it. Everyone has different needs and desires so if this one feature is the most important to you, running Cuddelinks in a network might not be for you.
