Do I need a contract for Ajax Security monitoring?

No. ASPEX Secure currently offers no-contract monitoring options, and customers can own their Ajax equipment, but final terms should be reviewed before installation. Pricing and payment options may depend on equipment selection, financing, monitoring requirements, and service setup. The current plans page lists Ajax equipment from $199 and professional monitoring from $29/month. ASPEX Secure can provide a clear quote before you approve the system design.
