Frequently Asked Questions
Have a question we didn't cover? Give us a call.
How much does a system cost?
It depends on the size of your building, how many doors or cameras you need, and the equipment you choose. We give you a clear quote after a free site survey.
How long does an installation take?
That depends on the size of the job. Small systems go quickly, and bigger projects take longer. We'll give you a timeline with your quote.
Can you work with my existing system?
Often, yes. We'll look at what you have during the site survey and tell you what can stay, what can be upgraded, and what needs replacing.
Can my employees unlock doors with their phones?
Yes. We install access control readers that work with mobile credentials, along with cards and fobs, so your team can use their phones to get in.
Can I see my cameras from my phone?
Yes. Every camera system we install lets you watch live and recorded video from your phone.
Do you work with homes or just businesses?
Both. We install cameras, alarms, TVs and audio for homeowners as well as businesses.
What area do you cover?
Manhattan to Montauk: all five boroughs of New York City, Nassau County and Suffolk County. We're based in Smithtown.
What is a free site survey?
We visit your home or business, look at the space and talk through what you need. Then we send you a recommendation and a quote. It's free, with no obligation.
