Drilling into stucco, hitting metal?

I'm trying to mount an outdoor security camera. The instructions seemed simple enough - drill two holes, mount the camera, done. Unfortunately, when I try to drill through the stucco I seem to be hitting something metal, or whatever it is, my standard cordless drill can't get passed it. Wondering what am I doing wrong, and what would be the correct way to mount the camera? Attached is a photo were you can see a few of the holes I've tried drilling. I'm getting stuck about a quarter of an inch in. My home was built in 2013.

 

You need not only drill mounting holes for the camera but you need to bring a cable out too.
Have you addressed the wiring ?

Pretty tough to see your holes. If I had to hazard a guess I'd say that stucco is over cement block or brick.

Rap hard on the stucco..... if it sounds hollow you are hitting something like a stud or pipe.
If it sounds solid.... that stucco is over masonry.

 

Could be metal flashing. I'd guess it's your drill bit as a cordless drill should easily have enough power. If you have inexpensive bits, have drilled several holes through stucco may be time for some new ones.

Wireless I'd wager!

 

What size cordless drill? I used 9.6 volt for years and when it died I bought a 19.2 volt - couldn't believe the difference!

 

An old timer told me that sometimes when the concrete and bit get hot that it forms a super hard glaze. He told me when the bit quits going in to take a masonry nail and poke it in the hole and hit it a rap and then drill some more. It worked, That must be why hammer drills work. Since it is only a few holes give this a try.
I agree you could be hitting concrete block or poured concrete which is harder than mere stucco. Or you could be hitting a steel column or pipe or something. Sometimes the hoddie made the stucco really rich which makes it harder. That quarter inch is the finish and a little more then the brown coat. It is possible that the stucco is that hard. I've seen it that hard so try the nail poke or a hammer drill.

You are using a masonry bit aren't you? A house built in 2013 in CA likely is thin coat stucco over foam, unless the house is block or poured. A masonry bit should go right through.
If you are hitting steel find out what it is then try a metal cutting bit.

 

Isn't there usually an expanded metal lath beneath that stucco ?

 

If this is frame construction then probably woven wire lath twenty gauge one inch mesh of seventeen gauge inch and a lad mesh. Even if there is expanded metal lath the drill should either go right through or glance off the steel into the key between the steel of the oath. I doubt if it a flashing or there would be a sign of it. I suppose there could be a nail guard. I can't see the holes in the picture to see if they are spaced such that they are all hitting the same nail guard.
I am guessing extra hard stucco or a concrete block or poured concrete.
Where in CA???
