DIY Security System vs Professional Install

How It Works
DIY cost is equipment plus your own labor valued at your chosen hourly rate (default zero, i.e., you treat your time as free). Professional cost is equipment marked up by a percentage plus a pro labor rate times estimated hours. We assume DIY effectiveness of 80% (placement and wiring can be suboptimal) and professional effectiveness of 95%. The chart shows the total cost gap; the time figures show the convenience tradeoff.
What Should You Do?
Pick DIY when the system is wireless and app-based, where installation is mostly mounting and pairing. Pick professional when you need wired sensors, structured cabling, or a warranty that depends on certified install. If you set your time value realistically (not zero), the DIY saving shrinks, so include your opportunity cost in the decision.
Frequently Asked Questions
Why is DIY effectiveness lower?
Assumption: self-installers sometimes place cameras with blind spots or skip sensors. Pros follow a coverage plan, modeled here at 95% vs 80%.
Should I really value my time at zero?
Only if you enjoy the work or have free time. Enter your real hourly rate to see DIY cost rise toward pro cost.
Does pro markup include equipment warranty?
The markup is a planning assumption for labor and overhead; confirm warranty terms separately with the installer.
Which is better for a rental?
DIY wireless kits are usually better for rentals because they are removable and need no drilling or permits.
Can I DIY part and pro part?
Yes, many people self-install cameras but hire pros for door and window sensors. This tool models the two extremes.
