Home / Blog / DIY vs Professional Install

The direct answer

Choose DIY if you can follow the device instructions and handle the required mounting, power and network setup. Hire help for tasks outside your skills and agree on the included work in writing. Installation method alone does not determine your service commitment, monitoring features or total cost.

	DIY installation	Professional installation
Setup time	Plan from the device list and mounting work	Ask for the appointment window and required preparation
Upfront cost	Include equipment, accessories, tools and any hired help	Request itemized equipment, installation and extra-work charges
Monthly monitoring	Confirm the required plan, enrollment and ongoing fees	Confirm monitoring separately from installation
Camera placement quality	Check the exact model guide and your intended view	Agree on locations and verify the view at handoff
Contract	Read service cancellation and equipment-payment terms	Read the actual offer; installation method does not determine the term
Portability	Check removal instructions, damage risk and reuse requirements	Ask what can move and what must stay or be replaced
Smart home depth	Confirm the exact devices and functions work together	Confirm supported devices, app functions and any required plan

When DIY is worth considering

You're renting — check the lease, required permission and the exact mounting/removal instructions. Adhesive mounting is not a promise of damage-free removal.
You have a simple layout — list the entries and camera views first, then check that the chosen equipment and connections cover those requirements.
Budget matters — compare the same equipment, required accessories and service functions over the same period. Include any tools or installation help you still need.
You might move — check which devices can be removed and reused, and whether moving changes equipment payments or service terms.

When professional installation is worth it

Complex layouts — ask for a placement and installation plan for difficult camera views, outbuildings or connection problems. Confirm what work the quote includes.
Smart home automation goals — list the devices and actions you need in one app. Have the installer confirm compatibility and demonstrate the agreed functions.
You want installation help — agree on mounting, configuration and testing responsibilities. You still need to confirm account access, app use and ongoing maintenance.
You need help assessing coverage — ask a qualified installer to explain the proposed device locations and remaining limitations. Installation alone is not a protection guarantee.

Check camera placement before finishing

Check the camera's intended view before finalizing its mount. Follow the exact model's placement instructions and inspect the doorway, delivery spot or entry path in daylight and after dark. Look for obstruction or glare, and confirm that the chosen setup saves the recording you need. There is no single mounting height that suits every camera and scene.
