Wi-Fi jamming to knock out cameras suspected in nine Minnesota burglaries -- smart security systems vulnerable as tech becomes cheaper and easier to acquire
Running wires is expensive. That's why most people opt for wireless, and on top of that, the convenience systems like Ring offer with their app, no NVR/DVR, none of the typical security system hardware cluttering things up.
No one should ever need to cut into your walls. A good tech will run down from attic or up from crawl space. The most you should ever have is a new plate where a box may be placed. If someone is cutting frivolously into your walls they should be fired. Hopefully they had contractors insurance too. Probably not if they were that incompetent.
Yep. With the solid walls I have, if you're not chasing into the plaster/brick, you're putting trunking on the outside (which looks pretty awful, imho).
I've run mine under the floorboards. CAT6e flat-band cables with multiple redundant outlets. Not a great solution in a finished house, but when redoing the floors, it's great. From room to room just drill through the wall below the floor level and pop the cable through. I've crimped mine myself so the hole is literally tiny, but even for a regular connector you don't need all that big a hole.
In case I ever need to replace them, I hope I'll be able to attach a new one to the old cable and just pull it through slowly.
The cost of the cable maybe, not the cost of all the ancillary work.
Most people have or want cameras in places where it won't be particularly easy to run wires, like door frames for door bells, and outside walls with insulation and various utilities in the way.
Other people live where they can't do it at all (an apartment)
