I have a question about IP camera ports
« on: March 02, 2017, 06:31:05 PM »
Hello,

I am a newbie and I have a question about IP cameras. I am interested in installing 2 IP security cameras in my residence. Since both cameras will be in the same LAN,  do the 2 cameras have to have different port numbers?

Thank you

#1 Well that depends.

#2 For LAN use only = No.

#3 For WAN/Remote use if you are trying to forward in the NAT router = Yes, some how and way the external port must be different.

For example in the NAT router

a) Rule Name = Cam1, External Port = 80, Internal Port = 80, LAN IP Address = 192.168.1.6, enabled = true

b) Rule Name = Cam2, External Port = 8080, Internal Port = 80, LAN IP Address = 192.168.1.7, enabled = true

Note: If a NAT router does not allow you to have the External port different from the Internal port, then the cams must instead have a different port that is used not only for Internet Access but also for LAN access.

May I ask another question?

Although I am pretty sure that every device on my LAN is using port 80, how would I know for certain? I logged into my computer as Administrator. I ran ipconfig and netstat. If the port numbers were there, then I missed them. I use Windows 7.

Thank you

Sure, here is the answer to that other question.

#1 Default ports

a) A web server unless SSL is used, the port is port 80.

b) A web server if SSL is used, the port is port 443.

#2 If you changed the default port, then after the IP Address or Domain name you must put a colon and then the port number.

For example if the fictional IP Address of 999.888.777.666 existed, non SSL web server, and the port was 8080 - then to access it

Code: [Select]
http://999.888.777.666:8080

#3 If using default port for the server while you could type in the port that it uses - ie

a)

Code: [Select]
http://999.888.777.666:80

you don't have to.

b) As well as, with most modern web clients/browsers - just enter in.

Code: [Select]
999.888.777.666

* This is assuming non SSL.

For SSL one must enter in https://
