Below, a verbatim post I made last month:

"Just received a Dahua IPC -T5442TM-AS Saturday from Andy and the included tool is same as my standard Torx T10 driver; the tool has a hole that a pin in the screw head would fit as many anti-tamper screws are, but your T10 will not need the hole, as the cam's screw did NOT have pin in it (at least mine didn't and I haven't seen a cam yet that did require the hole in the end of the bit).

So a standard T10 Torx should fit."

Edited 8/24: Torx driver or bit should be T10.

I just examined the four wrenches that came with my Dahua cameras. Interestingly: The three that came with the 5231s are all hollow. The one that came with the 4231F-AS is a smaller wrench, but for a larger Torx head, and is solid.
Do any of the Torx head screws on your cameras require a tamper proof tool?

All of my 5321-ze cams had the security torx screws and I just used what came in the box without any issues. I think for the OP the screw must have been cross threaded?

I know Aluminum isn't the most forgiving metal to work with, but before going full gorilla, I'd have tried a combination of nail set and hammer/mallet, propane/map torch (to cause some expansion/contraction; with an improvised heat shield of some kind), and various oils. You also might have been able to cut a slot in the set screw and then attempt to use a flat screw driver

Wow, what sort of speed did you have the drill set to?

What about long term? That shroud now can’t be used, wonder if Andy might be able source a replacement for you?

Mine snapped in my 5231 when i installed it - I've left it in there as i've not had to remove the camera but the tips in this post have surely given me ideas on how i could try and remove the broken bit!

I'm guessing the fixing was stainless steel and therein lied your problem.

For stainless you need a cobalt tipped drill. Even then, I've burnt one to pieces vs a stainless sink and it was a Bosch bit!

Also, nisnim's suggestion above is a good one - a strong magnet should pull the tip out as there's only friction keeping it in place. A good neomydium magnet should do the job if a normal magnet fails.

I've used magnets from this company before albeit never to extract a Torx bit. Good aspect of this supplier is they have some small round profiles that will fit into the centre alone. Whether the small ones have enough pull, I leave to your judgement.

The set screws on Dahua cams are stainless steel, so they would be a pain to drill out.

That being said, I have never seen one of these screws be anything more than finger tight. The included Dahua wrench is more than adequate for the job (I have one for daily use that I have used hundreds (if not thousands) of times) and the rest go into a box (getting very heavy lol) as spares when I open a new IPC.

If you broke the tool tip off in the set screw (and you know that its righty-tighty, lefty-loosey) there is something wrong (Cross threaded or mis-machined) and should be RMA'ed.

That's what I'd have done, but I'm afraid it's far too late for that for the OP.

Are you certain it was a T9 driver and not a T10? Because I finally got a set of Torx drivers, plus a T10 and T15. My 5231's are a T10 and my 4231F-AS a T15.

You're right...it IS a T10.

I went back and checked and sure, a T9 will fit (it's smaller) but could damage the screw...a T10 fits snug as it should.

What may have happened I was swapping bits in my driver to see what fit and I picked up the wrong bit or misread it. Glad you found the mistake, I'll edit my June and my July posts.
