Can I activate my iPad's camera remotely using my iPhone?

Working with iPad Pro (running on data, not Wi-Fi) and iPhone 6S Plus.

I'm in an ongoing war with my boss. We play pranks / scare each other for fun. I have a genius revenge plot to pull off, but I want video so I can relive the glory over and over.

Is there any way that I can use my iPhone to turn on the camera on my iPad to start the video before he rounds the corner towards my prank?

Would also be awesome if I can activate my iPad camera and keep the video recording while I simultaneously use the camera on my iPhone to record from a second angle.

Hi no it needs looking at by a tech
