Signal Blocking

[Scoobz]

Recently as with research to wireless or wired CCTV systms ive read that the wireless ones could be blocked ... where the thief/burglar has this electronic reader, blocker, that they use to get cars opened without the keys as it is reading the signals from within the property, and that these can ALSO be used to BLOCK the signal of ANY wireless system, so perhaps a WIRED system although harder to instal is the SAFEST option ? or does ARLO prevent this from happening in their hardware ?

WiFi jammers can block the signal from the Arlo cameras, and there is no way to prevent that from happening.  They are illegal in most places.

Car key fobs use completely different frequency bands from WiFi.  So I don't think a device designed to read the key fob traffic would interfere with wifi.  A wide-band jammer could potentially interfere with both radio bands though.

You can by a Deauthur from a well known auction site for about £20 sadly and can be as small as a watch and worn as such. What you do need is a router with PMF in its settings. PMF  provides protection for unicast and multicast management action frames. Unicast management action frames are protected from both eavesdropping and forging, and multicast management action frames are protected from forging and work with WPA2 AES/WPA3 . That's the best you can do to protect yourself. Or get a Arlo Go and hope nobody has a cell phone jammer or better still a wired setup.
