What kind of traffic comes from analog video recorders?

Question

CCTV

Good evening. I fell into the hands of a piece of iron from praxis, with the command "I want to watch on the phone", it worked at another point. The standard port-to-port traffic loop gave only the login page and reset the connection with the reg when trying to login. What could be?

Answer 1

25 page of official documentation - see also others.
in addition to forwarding port 80, another 6036 is needed,
I would also look at nmap as an option
