Winner and Loser Categories

Packages, Equipment and Pricing

Winner: Tie

ADT and Alarm Grid both offer packages with high-quality product options and extensive available add-ons like cameras and glass break sensors. Alarm Grid requires users to purchase equipment upfront, while ADT does not. But, ADT packages are barebones and will more than likely require additional add-ons at significant out-of-pocket cost.

ADT packages run approximately $30-$50 a month depending on features and come with round-the-clock monitoring but only equipment essentials. The company primarily uses excellent Honeywell/Ademco or DTC technology.

Alarm Grid uses Honeywell products, and the company has separate upfront equipment costs and month-to-month monitoring options. There are 25 equipment packages ranging from under $200 to over $600, with monitoring plans ranging from $10 to $45 a month.

Full Alarm Grid review

ADT and Alarm Grid both offer excellent home security options, though will likely appeal to different customers. Those looking for a well-established company with professional installation and traditional long-term monitoring contracts should go with ADT. Those interested in DIY installation who are willing to take a chance on a newer company — or those who have interest in flexible month-to-month contracts and self-monitoring — should opt for Alarm Grid.
