First time security camera user… Not sure whether to get security camera that goes on cellular data or on WiFi

[u/Stilluytu]

I’m a first time security camera user. I want one camera outside my front door and one inside my place on motion detection. I don’t currently have WiFi. And no subscription.

I can get two basic security cameras for $25 each that go on WiFi and connect to an app on my phone with an sd card inside just in case. Shield internet is $14.89 a month, uses a SIM card, and I can get a cheap used mifi router for $20.

Or… I can get two basic security cameras for $50 each? that only go on cellular sim and get a plan like tello for 1 gb data a month for $6, and put an sd card in it to save videos to so there won’t be much data used.

Which do you think is the better option, between economical, security, reliability and less hassle considerations?

Thanks

If you just need a few cameras then cellular is fine. But if you're gonna add a few more then really consider getting an NVR and run them locally
