I'm a great one for drilling holes. To get the Hawk Eye's AV cable into the house, simply drill through the nearest wall, and run the cord through. Of course you must be sure to avoid any electrical wires or water pipes, and be sure to calk the hole shut. Annnndddd have a very understanding spouse.
A 3/4" hole allows plenty of room to thread each individual plug at the end of the cable to be threaded through. Seal the hole with a bit of waded up paper if it's only a temporary installation. Or used expanding foam or calking for a permanent seal.
Your spouse isn't too keen on that idea? OK, then run the cord under a door. Most have a 1/4 "+ gap between the floor and door, which is sealed with a flexible plastic or rubber weather strip. Most doors will easily close with the cord running beneath them.
That won't work? How about through a loose fitting window jam?
That won't work? Do you have a sliding door? There's quite a gap between the sliding part of the door and the permanent, non-sliding side. This is sealed by a rubber gasket or flap through which the camera cord can easily be pushed. Make sure the cord is then attached to the floor or baseboard so that it does not fall into the track the door slides in.
