drilling through residential siding

[rec777 0]

im installing cams in a new construction house, i will be drilling through the newly installed siding into the wall space inside the new home, interior is still studs. i was planning on using silicone on the outside and foam sealer on the inside for a seal. I'm installing a qsee HD system which come with rj-45 jacks and jacket over the jack where you plug the wire into. These require about a 1/2 hole and i would need to leave slack on the inside of the house incase the wire needs to be pulled out incase camera needs changing... I don't want to install boxes , but why are they designed like this? a bigger hole in the house to stuff the plug assembly in, they should design them so the connector can get stuffed into the camera arm..Am i missing something here? seems like common sense?
