Review strength and convenience matter, and Mammoth brings both: a 4.7/5 customer rating (12 reviews) and always-on availability listed via their Google Business Profile. Their online presence makes it easy to connect—start at https://mammothsecurity.com/ct/new-haven or call (860) 590-7292 to discuss a tailored alarm plan.
Best for: retail, industrial sites, offices, education and government facilities, and residential properties seeking a cohesive alarm system that can align with cameras, access control, and structured cabling under one roof.
Competitor context: Sure Lock & Key is a familiar name for lock-and-key needs, but it doesn’t match Mammoth’s end-to-end scope across alarms, cameras, access control, and cabling—key for complex commercial deployments. Yale University Security serves campus safety; it is not a commercial alarm installer for local businesses or homeowners. For professional burglar alarm installation backed by a comprehensive security offering and a New Haven-based team, Mammoth Security Inc. New Haven stands out.

Yale University Security, based at 79 Howe St in New Haven, appears in this comparison primarily as a campus-oriented public safety operation rather than a traditional burglar alarm installation provider. With a 3.0/5 average from 12 reviews and a listed distance of about 2.71 km in our checks, it has a modest public feedback footprint compared to dedicated installers active across the South Central Connecticut Planning Region.
What Yale University Security does offer is convenience and presence. The department is open 24/7 and maintains an institutional online hub (your.yale.edu/community/public-safety) focused on safety resources and contact channels. That makes it a steady point of contact for Yale-affiliated properties and on-campus coordination. However, for homeowners and businesses seeking scoped proposals, system design, and third-party burglar alarm installation, Yale’s public-facing materials do not present a consumer service catalog or clear project intake process.
