This gist is a few files that I use to update my DuckDNS internal and external IP addresses,
and report update status on the RPi-Monitor

on the raspberry pi with the camera attached:

libcamera-vid -t 0 --listen -o tcp://0.0.0.0:8888

on the client (my mac laptop)

ffplay tcp://10.39.6.55:8888 -vf "setpts=N/30" -fflags nobuffer -flags low_delay -framedrop

Notes:

Obviously, change the IP address in the client command to the IP or hostname of the raspberry pi. The picture quality isn't super great, but when setting up the frame for a time-lapse shot this gives a quick view of what's in the picture and may help with initial focus.

GPIO.setmode(GPIO.BCM)  # Use Broadcom GPIO numbers
                        # not BOARD for pin numbers
# This example is based on using the buttons in this hardware:
