I have CCTV camera and camera which I’m trying to connect via Ethernet and get both power and data. I would need to drill a hole on the brick wall to pass the Ethernet cable from outside to inside.

The camera is ieGeek IG82 outdoor camera. The reason I wanted to have Ethernet is that it’s more stable than wireless and less chances to get disconnected due signal loss.

My Ethernet cable is terminated. And I don’t know how big is the hole that I need to drill for.

Any suggestions? Or, alternatives?

  • don't you have a scrap piece of wood where you can drill some test holes? – jsotola Jun 8 at 23:59
  • I'd guess not owning drill bits that large, and not wanting to buy a whole range of drill bits that large. – Ecnerwal Jun 9 at 0:27
  • @Ecnerwal then cut holes in cardboard ... poke holes in styrofoam ... there are lots of ways to make a hole to test if cable would fit – jsotola Jun 9 at 6:32

Don't use a terminated Ethernet cable.

Just don't. It never works in the long-term.

Run an unterminated Ethernet cable. Install a jack on each end. Use standard patch cables to get from the camera to one jack and on the other end to get from the other jack to the switch or router.

The hole you need will be on the order of 6mm - 8mm, or ~ 1/4" to 1/3". Figure at least double that diameter (and 4 times the area) for terminated cables to get through.

5/8 inch is the bare minimum. You can fit a terminated cable through a board with a hole that size.

To actually get through a wall, 7/8 inch is more like it. 5/8 does not leave enough room to get anything to pull the cable with attached without jamming, and walls are generally too thick to just push through.

Yes, that's a huge hole. Suffice to say that a customer had a delusional scope of work, so we followed it while shaking our heads. Whole lotta caulk.

Practically speaking, since weatherproof jacks/plugs are prohibitive, buy exterior rated (for whatever reason, direct burial has been the best search term for those, though I don't advise direct burying them) pre-terminated patch cables twice as long as you need, drill the 1/4 - 5/16 inch hole through the wall for the cable, cut the patch in half (or divide as needed if not half is better), plug into the camera outside and run the cut end through the wall to a jack (or crimp a plug on it.)

    If you do this, definitely better on the "inside" half to punch it down to a jack than to crimp a plug on it. – manassehkatz-Moving 2 Codidact Jun 8 at 23:30
