This morning I rigged up a security camera in my growroom for 0 (zero) dollars.
Dirty old iPhone 4S
Free pivoting selfie stick
Dirty old power cord.
I used an app called Alfred. It is buggy, laggy, and low resolution. You can pay to upgrade these things. I won’t.
Just install the app on both phones, mount it as best you can, and that’s it.
This is the rig.
Here is the view of a lonely Pink Cookie
You just can’t argue with FREE!
Edit: it took about an hour and that includes the 45 minutes it took to update the ancient phone.
