Choose by the job you want the system to do. Ring is worth comparing if you already use Ring cameras and want to add an alarm. SimpliSafe gives you a choice between alarm monitoring and a plan that also saves camera clips. Vivint is worth a quote if you want a technician to install a system and compatible smart-home controls. Match the equipment and service before comparing the monthly price.

How we evaluate
No brand pays to appear higher or lower in our lists. This comparison uses the manufacturer documents linked below; we have not measured installation time, response speed or protection outcomes for these three systems. Read our review methodology →
All affiliate relationships are disclosed transparently. Read our disclosure →
These are starting points for a shortlist, not a measured reliability ranking. Equipment, installation and any permits are separate from the service figures below.
You already use Ring cameras
Build: Price the Alarm base and sensors separately from the cameras you own.
Service: Ring Pro: $19.99/month plus applicable tax. Eligible alarm monitoring needs an Alarm or Alarm Pro Base Station and completed enrollment.
Check: Pro includes camera-plan features; this is not the same service as live video monitoring by agents.
You want to choose the level of service
Build: Build the same sensor list, then choose DIY setup or optional professional installation.
Service: Standard: $22.99/month. Core: $32.99/month. Standard excludes camera recordings; Core includes them.
Check: For agents to speak through a camera during an indoor alarm, check the Smart Alarm Indoor Camera and opt-in requirements.
You want an installed system and automation
Build: Ask for an itemized quote with the exact cameras, sensors and compatible locks or other controls.
Service: Use your written monitoring quote; compare equipment and installation separately.
Check: Verify the service term and any financing agreement. Paying upfront is an advertised route to month-to-month monitoring, not a promise about every account.

Start by listing which Ring cameras you will keep, then add only the alarm base, sensors and accessories needed for your home. Camera ownership by itself does not enroll an alarm in professional monitoring.
Read the monitoring enrollment requirements and Pro feature conditions. For a DIY alarm, plan time to place and test each sensor; we have not timed a comparative installation.
A useful starting question is whether you need saved camera clips. Standard provides professional alarm monitoring without recordings. Core adds recordings; camera intervention is a separate feature with hardware and permission requirements.
Compare plan inclusions, camera intervention requirements and installation options before ordering. We have not measured a reduction in false dispatches or a response-speed advantage over Ring or Vivint.
Vivint’s offer is an installed system with monitoring and compatible smart-home equipment. Its practical advantage for a buyer is having an installer handle the agreed setup. Decide whether that service and the specified devices are worth the complete quote; a higher price does not establish better protection.
Use Vivint’s installation overview and financing overview to prepare your questions. This review does not establish faster emergency response, superior camera performance or a quantified protection advantage.
A cheaper monthly plan can leave out the service you wanted. Make one requirements list and use it for all three offers:
Before signing: record the recurring price after any promotion, renewal and cancellation terms, and what remains usable if service ends. Keep any equipment loan separate. Ring subscriptions renew until canceled; SimpliSafe bills its residential plans monthly without a long-term monitoring contract; Vivint offers different payment arrangements. None of those facts makes every exit balance zero.
