I use tinyCam Pro on my Amazon Firestick. I loved it very much and very useful to see who at the door at the press of a remote button.
If your TV support CES and if your watching TV and
doorbell rings, just grab the Amazon Firestick remote and press a button, it'll force the TV to change source over to where the Firestick is plugged into and you can see who's at the door. Also you can have several different camera and switch view between each one at the press of a button.
And the developer is awesome too! One time the developer add some feature which broke tinyCam on Firestick. When I emailed him about it, he quickly released another version to correct the problem.
One thing I would like to see is to be able to play back files stored in each camera, I don't have a NVR so all my recordings are stored on scandisk in each camera. I plan to replace camera soon and start storing recording elsewhere but I am not sure if I should go with one of the Hikivision NVR or get a desktop and use BI ... decision decision decision ....
