Does anyone know of a software I can use to hook up old webcams and phones as security cameras for monitoring?

I don't have a static IP address, so it would need to stream through a server somewhere

I'd like it to have a dashboard where I can select which camera to view or view multiple streams at once

Just invest into a security system. They're like 500$ for a super cheap set of shitty cameras. They'd be the same quality as a webcam.

IP Webcam for Android phones.

Should be pretty easy to create a simple website for multiple streams.
