Our company had surveillance cameras installed throughout the perimeter of our warehouse by Three Factor Security and they did a great job with installation and setup.

After calling numerous companies about getting a security system installed on our apartment building, I was pleasantly surprised when the kind people at Three Factor not only answered, but were actually knowledgeable and very helpful.

They installed a new system and all new cameras and integrated everything seamlessly. They went above and beyond in every conversation, taking extra time to answer all of my questions at every stage of the process.
Common questions
Clear answers before the project begins.
These answers explain practical planning considerations for this service. Final recommendations are based on a professional assessment, the existing infrastructure, the property’s operating needs, and the systems selected.
How does security talk-down work?
A supported system lets an authorized user or enrolled monitoring operator issue audio through speakers at the property. The camera view, speaker coverage, connectivity, permissions, and approved workflow need to work together. Professional operator intervention depends on the independent provider’s monitoring agreement.
What determines whether an announcement will be understandable?
Speaker selection and placement, background noise, distance, the environment, power, and the audio source all matter. Review the intended audience and test intelligibility in actual operating conditions. Adding a louder speaker alone does not establish useful coverage.
Can security speakers also support paging?
Some platforms support both authorized security messages and routine paging, with suitable zones, schedules, and permissions. Confirm the selected equipment and integrations before combining functions. Security audio should not be assumed to replace a separately required life-safety communication system.
What should be tested before audio is handed over?
Check the intended speaking and listening paths, authorized controls, zone selection, network and power dependencies, and the agreed use of recording or microphones. Test supported camera or monitoring integrations and train the people who will operate the system.
