How much does it cost to have a security system professionally installed?

By published pricing as of August 2026: $124.99 to $224.99 flat for a SimpliSafe system through OnTech depending on piece count, starting at $129.99 per device at Ring, and $199 at Vivint per its HomeProtect offer terms (currently advertised as free for new customers). ADT prices installation within a custom quote rather than publishing a flat fee.

Is professional installation required for a monitored system?

No. SimpliSafe states that regardless of whether you install your system yourself or select Pro Install, you can still choose the monitoring plan that best meets your needs, and Ring's monitored Pro plan works with self-installed kits. Professional installation is required in practice only for hardwired systems and for providers like Vivint, which states all its security system purchases include professional installation.

Why does ADT not publish an installation price?

ADT prices systems through custom quotes that bundle equipment, installation, and a monitoring agreement; its published offer terms reference install and early termination fees but not a standalone install price. If a provider quotes you a bundle, ask for the install fee, equipment cost, and monthly fee as separate line items.

What extra installation charges should I watch for?

Wiring work is the main one: Ring states that modifications and extensions to existing wiring are available at additional cost and billed separately. OnTech's camera, doorbell, lock, and standalone smoke installs are separate line items at $129.99 each (50% off when purchased with a multi-piece package) rather than part of the flat package fee. SimpliSafe's support page also warns that failing to give adequate notice of rescheduling, or not being home during the scheduled window, could result in additional charges from OnTech.

Is DIY installation actually free, or am I trading my time?

It is a real afternoon for a full kit, but wireless systems are designed for it: peel-and-stick mounting and app-guided pairing, no wiring. If the system is large or involves wired devices, the published flat fees ($124.99 to $224.99 for up to 30 pieces via OnTech) are modest insurance against a botched setup.

Security System Installation Cost: Every Published Fee, Compared

By published pricing as of August 2026: DIY installation is $0 and is how most modern systems are designed to go in. Professional installation of a DIY-style system runs $124.99 to $224.99 flat through OnTech, the provider SimpliSafe's support site names for its Pro Setup service, or starts at $129.99 per device at Ring. Vivint's HomeProtect offer terms price professional installation at $199, currently advertised as free for new customers. ADT does not publish a flat installation fee; its pro-install path is priced by custom quote. The real cost driver is not the install visit, it is the contract that sometimes rides along with it.

Published installation fees, provider by provider

Here is every installation price we could verify on official pages, as of August 2026:

Provider	Published installation cost	Notes
SimpliSafe (self-install)	$0	Systems designed for self-setup; monitoring choice unaffected
SimpliSafe via OnTech	$124.99 (up to 10 pieces), $154.99 (15), $184.99 (20), $204.99 (25), $224.99 (30)	Camera, doorbell, smart lock, and standalone smoke/CO installs are separate: $129.99 each, 50% off when purchased with a multi-piece package
Ring (self-install)	$0	Kits designed for self-setup
Ring professional installation	Starts at $129.99 per device	Modifications and extensions to existing wiring cost extra and are billed separately
Vivint	$199 per HomeProtect offer terms, currently advertised as free for new customers	Vivint states all security system purchases include professional installation
ADT Pro Install	Not published as a flat fee; priced by custom quote	Published offer terms reference install and early termination fees; ADT's published pro-install monitoring floors run $45.99 to $56.99 per month depending on the page, and the 36-month contract is attached to the $56.99 offer

Two patterns worth noticing. First, the DIY brands price installation transparently because it is optional: a flat fee for a defined visit. Second, the traditional pro-install brands fold installation into a quoted bundle of equipment, install, and a monitoring agreement, so the install fee is a negotiating lever rather than a list price. Neither approach is wrong, but only one lets you comparison shop from your couch.

A note on ADT's numbers: it publishes different pro-install monitoring floors on different official pages. Its monitoring plans page FAQ says Pro Monitoring starts at $49.99 for Pro Install, its Own vs Rent and Self Setup pages both say pro install starts at $45.99 per month, and its Self Setup page footnote pairs a 36-month monitoring contract with a $56.99 per month starting price. We quote each figure with the page it appears on rather than blending them.

What the install fee does and does not buy

A professional installation visit at the published prices above generally covers mounting and placement, connecting devices to Wi-Fi, first-time configuration, and a walkthrough of the system. OnTech's published SimpliSafe packages list installation of up to 30 SimpliSafe products, confirming products are compatible with the home, connecting to Wi-Fi and performing first-time setup, customizing device preferences, configuring products with the SimpliSafe app, and teaching you how to use the products and app.

What it typically does not include: electrical work beyond the device itself, wiring modifications (Ring states that modifications and extensions to existing wiring are available at additional cost and billed separately, with extension available only for low-voltage wiring), or drywall repair. If your job involves running new wires, expect the flat fee to grow.

Is paying for installation worth it? For wireless DIY systems, the work is genuinely simple: peel-and-stick sensors and an app-guided setup, which is why self-install is the default and $0. The published fees make sense when you have a large system (30 sensors is a long afternoon), wired doorbells or locks, cameras at height, or you are setting this up for a relative remotely; our home security for elderly parents guide covers that scenario. For hardwired retrofits, professional installation is effectively mandatory and quoted per job, since no provider publishes flat pricing for in-wall work.

Remember that installation is a one-time cost sitting on top of recurring monitoring, and the recurring side dominates over a few years. A $199 install amortized over five years is $3.32 per month; the difference between two monitoring plans can be ten times that. The full recurring picture is in home security cost per month.

The contract attached to the free install

Free or discounted professional installation at the traditional providers is generally financed by the monitoring agreement. ADT's published Self Setup page footnote states that pro install comes with a 36-month monitoring contract starting at $56.99 per month, with early termination and install fees noted in the same line. Vivint's currently waived $199 install fee comes with the purchase of a system whose HomeProtect offer terms price equipment at $349.99 and monitoring at $29.99 per month; Vivint's separate financing terms state that month-to-month service agreements are available when equipment is purchased upfront, which implies a service agreement otherwise.

The arithmetic to run before signing: 36 months at $56.99 is $2,051.64 in committed monitoring. Against that, a one-time $124.99 to $224.99 published install fee on a no-contract system is small. This is not an argument against pro-install providers, whose service includes things DIY does not, but the install fee is the wrong number to anchor on. Compare the total committed cost, then decide.
