Please accept this as a regretful letter of cancelation of service for my deceased mother's two residential alarm services. I convey Mom's undying gratitude for the many years of dedicated, prompt, and efficient service, as well as the friendship you have all offered in the process.
A fantastic alternative to monolithic alarm companies that get you locked into multi-year contracts. Greater Los Angeles Patrol did a great installation at a great price for a Wired Alarm System (not that wireless junk). On top of that, they have a monthly charge for monitoring, with no contract, cheaper and just as good as the big guys.
Fabulous service form a family-owned business, with a real focus on personal care and attention. Highly recommend anyone looking for an alarm installation and monitoring company to call these guys.
I couldn't be more happy with the professional service I have received from Greater Los Angeles patrol. I have saved money and still maintained a safe environment for my family.
