I've figured out more. Turns out the RL400 camera is shipped with the factory IP address 192.168.100.88. This isn't assigned via DHCP as our prior stake center upgrade engineer stated.
https://support.getcleartouch.com/porta ... -the-rl400. That helps explain some things. The reason that I can't see any packet replies is that none of the building's subnets connect to that IP address. Any TCP or UDP packet I send to that port can't get routed.
Looks like the answer is any of these three. 1) Get my computer somehow onto that 192.168.100.X subnet and hook the camera up to that same subnet (I located the camera's ethernet cord on the rack). 2) Ask the church to change/create a subnet range that includes 192.168.100.88 3) See if there is a way to change the camera's IP address, the documentation refers to it as "default", but I don't know if it's changeable.
#1 is a mess, it would require two ethernet adapters on the laptop (one for broadcast streaming, another for camera connection). It would also require adding cords, and a big point of IP connectivity is to reduce cords.
#2 is an option?
#3 seems like the best first approach.
I also found the manual for the original Chinese version of the camera, and it also has a 192.168.100.88 default address. Looks like this manual is the way to go:
https://www.manualslib.com/manual/15995 ... =14#manual. Looks like if I can get on that subnet, I'm able to change the camera's IP address, the camera appears to have a web interface. Looks like I've got a plan to try for next Sunday.
I don't know about the RL500 camera. I assume there are similarities here? But I can't find the RL500 on the valuehd website. twrhodes, I think your next step is to log into the CNM, pull up the all the devices listed in your Public zone, then hopefully you will see a row like: UHDCamera 192.168.100.88 d4:e0:8e:8a:f9:fa ValueHD. That last one gives you the true manufacturer's name, and from there we can hunt down a manual.
