Install home security camera (Semi-Detached house)

You can definitely install it yourself if you're comfortable drilling, fishing cables through walls, and setting up networking equipment. The biggest challenge is usually running the Ethernet cables outside cleanly and weatherproofing everything properly. For a semi-detached house, a professional installer can ensure the cables are routed neatly, sealed correctly where they exit the home, and that the cameras are positioned and configured for the best coverage. It also saves you a lot of time and avoids potential damage from improper installation. If you'd like, I can take a look at your house layout and give you some advice, or provide a quote for a complete installation and setup.
