The Nest Secure system costs $399, with no service contract required. Payment plans can be arranged via Google Store Financing. Monitoring service packages are generally lower than Link Interactive’s. However, Link Interactive’s starting prices are lower. Its standard security system is $251, while the premium system is $331. The best price option for you will depend upon your preferred budget for startup versus monthly costs, and your comfort with long-term contracts.

Though the Nest Secure alarm system doesn’t come with a built-in camera, it does come with motion detectors and offers other high-resolution features. Both brands offer advanced image analytics that can distinguish pets and people from objects, but Nest’s algorithm is ahead of the curve with individual facial recognition. However, Link Interactive does offer a wider range of equipment with security-specific purposes, including motion sensors, glass-break sensors, and panic buttons.

Nest offers the most flexibility and coverage for the monthly costs associated with professional monitoring. For those who want professional monitoring, Nest’s service is fulfilled by Brinks and starts at $19/mo. with a three-year contract. Month-to-month monitoring is available for $29.99/mo. Link Interactive requires professional monitoring through contracts spanning one to three years, at $30.99–$44.99/mo.

Both providers offer extended warranties on their equipment, so this is a close call. However, Link Interactive’s three-year warranty beats out Nest’s two-year warranty, giving you peace of mind for a bit longer. Neither provider offers theft protection or other guarantees.

Both brands design their products for easy DIY installations, but Nest is the only one to offer professional installation services for those who want it. Nest installation appointments are provided via a third party, OnTech, and start at $99.

On top of a mobile app, Nest’s devices can be easily controlled with Google Voice Assistant. You can use voice commands to change your alarm settings, access live views from your cameras and even remotely lock doors. Link Interactive’s products do offer many home automation capabilities, controllable through keypads and a mobile app. Despite this, the experience just isn’t as seamless and modern as Nest’s.
