Help with retrieving file list over HTTP with Python

Sorry in advance because I am very new to python and programming. I have an IP camera that captures clips to it's SD card, with an internet connection provided by a cradlepoint router. I am able to reach the camera's SD card remotely with a CGI call to a static public IP that is given by the cradlepoint. (The CGI call looks like: 166.x.x.x:port/blackvue_VOD.cgi) Which will present me with a list of MP4 files that can be downloaded. ultimately, I'd like to create a bit of python script for retrieving those files as the camera captures them without having to use the CGI call every time.
What I have so far is:

import urllib.request
x = urllib.request.urlopen('52.x.x.x:1206/blackvue_vod.cgi')

print (x.read())

(I've X'ed out the IP for privacy)
But when I run this, I will get an error: ValueError: unknown url type: '52.x.x.x:1206/blackvue_vod.cgi'
I know it's not alot to work with but can someone point me in the right direction for retrieving the files?

Thanks!

urllib.request
CGI.fieldstorage (very new concept to me)
