The direct answer
DIY installation is right for most homeowners and renters — lower cost, no contract, setup in under an hour for most systems. Professional installation is worth it when you have a complex layout with many entry points, want smart home integration beyond your DIY comfort level, or need cellular-backed monitoring without any setup work.
| DIY (SimpliSafe, Ring, Arlo) | Professional Install (Vivint, ADT) | |
|---|---|---|
| Setup time | 30 min – 2 hours (self-paced) | 2–6 hours (scheduled installer) |
| Upfront cost | $150–$600 | $800–$3,000+ |
| Monthly monitoring | $0–$20/mo (cancel any time) | $29–$60/mo (often 36–60 mo contract) |
| Camera placement quality | Up to you — common to miss angles | Professionally assessed, calibrated |
| Contract | None | Required (36–60 months typical) |
| Portability | Yes — move it when you move | No — wired into the property |
| Smart home depth | Moderate (Alexa, Google, Z-Wave) | High (locks, lights, thermostat, cameras in one app) |
Poor camera placement — specifically, mounting cameras too high (above 9 feet) so they capture tops of heads instead of faces, or aiming cameras toward bright windows/sky so backlighting washes out footage. These placement errors eliminate most of a camera's practical value. If you go DIY: test your camera angles at night before finalizing mounts.
