You set up an account with Tactacam and link a credit card to it. Every time you buy a camera it has the correct sim card already in it, you scan the code on it with your phone, and name it and add it to your account, which adds the monthly or yearly price of another camera to your plan. Then you can go on your account and view pictures and change every setting on every individual camera that you have. If you have new pictures it shows up on the Tactacam icon on your phone. To see the latest pics you tap your Tactacam icon on your smartphone or PC and it shows you all your pictures with the most recent first.
