Drill a hole in the location where the outlet will be (for wireless and analogue security cameras), and feel within the wall with a straightened metal coat hanger for any unforeseen blockages. Drilling is undoubtedly one of the easiest ways to run security camera wires through walls, soffits, vinyl siding, etc. However, not everyone is comfortable with drilling into their walls. Wireless, battery-powered cameras like the EufyCam 2 or the Reolink Argus 3 will be the easiest to install on your own. If you have an indoor security camera, then those are also quite easy to set up yourself.
