What clients say.
★★★★★
First, we spoke with Isaac who was very receptive to what we needed. Then Alex came out to our home to assess the situation and give us a free estimate for the work involved. His pricing was very fair and competitive to other quotes we'd received so we scheduled the project.
★★★★★
I needed new security cameras for my business and spoke with Javier on the phone... He came to site and surveyed situation and we came up with a deal that was good for me and agreed on the proposal.
★★★★★
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.
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.
What information is useful for a security design assessment?
Start with property use, operating hours, the problems to solve, authorized users, existing systems, and investigation or retention needs. Note pathway, mounting, power, network, and work-access constraints. Sensitive plans and credentials belong in an approved private exchange, not a public inquiry.
How are cameras, entry systems, alarms, and networking planned together?
Define the intended operating tasks first, then identify the devices, interfaces, power, connectivity, recording, permissions, and support needed for each task. Review integration compatibility and who owns each dependency. Equipment selection follows that coordinated scope.
How should commercial requirements differ from a home system?
Commercial planning often involves several administrators, employees or tenants, more complex infrastructure, longer investigation windows, and coordinated work hours. Residential planning may prioritize family use, visitors, privacy, and appearance. The property’s actual operation determines the design, rather than a preset package.
What should a proposed design make clear before installation?
The agreed scope should identify system functions, retained and proposed equipment, installation considerations, integrations, limitations, responsibilities, verification, and handoff. Required professional reviews and approvals depend on the work. Future expansion and maintenance should be considered while the initial design is being settled.
