How can i capture video from an external camara!

#1

Can i capture a video feed from an external camera…maybe a camera that i connect with Bluetooth or to the phone WiFi…
I can listen music with my beat Bluetooth earphones, right? so i want to grab video feed from a body worm camera as well and display it real time in my ionic app…

i have been looking for a while…but none has been able to point me into the right direction!!!
