That's a dangerous illusion when applied to pretty much any broadcast technology; you never really know who's listening.
Dan, are you getting DDoS attacks on your network? The Anran firmware in the DVR's we use have a telnet vulnerability issue with Mirai botnet. Cold booting everything on the network clears it out but if there's crap you've downloaded that's bad, it'll come back.
I don't worry about it on mine cause I have things secured pretty good here and haven't had a problem.
It would probably be a lot easier to just do away with the gateway address (or set it to a something invalid) on the XP clients. In the event that the router gets changed out, they still won't be able to access the Internet.Then created an access rule to explicitly deny inbound and outbound WAN to LAN access but allow LAN to LAN for that IP range.
Routers in the home context is anything that acts as an Internet gateway (this includes "gateways" that are routers with modems -- and possibly other functionality including VOIP -- built in). They behave more like a firewall than a network traffic director. DHCP can be wherever you want it or you can run without it. That said, static IP on Wi-fi can be "interesting" for guests and infrequent users.Not that it matters, but at work we don't use routers.
Look at it from a different point of view. What viewing software can you get for the phone? What does the software need to function?Well this is what I wanted to do is this. My mom asked me if she could have something on her phone or TV that will send a signal from my CCTV system to her tv or her phone in her room. Would it be more work with a home network or just use a wireless video signal sender?
Is there anything required to choose from among a series of cameras or is this "system" just one camera at the door?My mom asked me if she could have something on her phone or TV that will send a signal from my CCTV system to her tv or her phone in her room.
With a sender she'll have to switch inputs on her TV and that may lead to troubles getting back to watching TV. If it is a true network of cameras, picking out the appropriate camera may require an app (unless the switch uses motion detection to present cameras with something going on). If you have to push a button or diddle an app to get a particular camera to go full-screen, the transmitter/receiver configuration is probably off the table.Would it be more work with a home network or just use a wireless video signal sender?
