Since forwarding ports 8000, 554, and 84 is necessary to have real time viewing from a computer and cellphone how secure are our camera feeds? Going to www.grc.com and doing a port scan ports 554 and 84 and 8000 are open and respond to probes. This means theoretically someone can connect to and attempt to break into our private feeds. Other than closing all ports and disabling viewing from smart phones can anything be done to secure this? I feel like our passwords could easily be broken?
