Need help finding a security camera app

[Gravemind]

I need a security camera app that meets these requirements.

1. Android

2. Free with no subscription required

3. Works 100% offline with no access to internet or cell services.

4. Has motion-activating mode

 

I have an older-ish Android phone I need to turn into a motion-activated camera for a small interior space. It will need to work with no access to a cloud(no internet here whatsoever) so it'll need to work off of its' own internal storage I can access later. Anybody know an app that'll work for that? I'd just download and try a lot myself but my phone that has internet here is borderline unusable with my location+crowded towers. I'm barely even able to post on these forums. So I need to know I won't be wasting my time.

 

Apologies if this isn't the right place to post it, really wasn't sure where this belonged.

The Nest app is just for monitoring Nest products.

Alfred doesn't save locally, just streams and it can't do that once it's in position.
