Professional and responsive. I've used their services on a couple residences and the work has always been top notch.

They were to blame for false alarm(their faulty equipment plus not following my instructions for calling the police) and the calling of police causing me $189, they even said you get one false alarm free of charge which wasn't the case and they wouldn't credit me the money. I would have won with my credit card company as I have the emails to prove my case but I missed the cut off response by one day, I wouldn't recommend this company. Also, they held the alarm panel hostage with dealer code, that is always a sign of a sketchy alarm company. Just DIY as I learned and check out Alarm Club.

This alarm service was installed in my home when I purchased it. I got quotes from other alarm companies and these guys were the most reasonable and pretty easy to work with (ADT is the worst). I wasn't sure if the alarm actually worked, but someone set it off the other day and didn't know the code to turn it off and sure enough the police were dispatched. The alarm is installed really well too. Good job and keep up the good work.

They used to be good at service but now offers 0 service. I guess that's the pain of small mama papa shop! I stopped referring them customers.

Horrible service. Install half way then mention additional fees required and forcing us to sign contract that is never been agreed on. Technician left without finising his work and no follow up when he will be coming back. To make the long story short, our original parts were destryoed and Beta Security sales yelled at us. Very unhappy ending.

We are a current customer of Beta and was recently robbed. Beta contacted the police very very quickly and the thiefs only stole a few items since the police arrived within 5 minutes. Great job Beta! If you need a good security company, Beta is the one!

I have been a customer of beta security for 4 years and always paid my bill in advance every time I get a statement from them. However, when I decided to cancel them because i have decided not to have a land line, Beta Security refused to cancel me and said that the contract roll over every two year if I don't cancel them after my two years up.

After I had pointed out to them that I have paid them on time every 3 months for over 4 years, they gave me one month refund instead of my 2 1/2 months refund. This partial refund happened after about 5 phone calls to request my refund. This company is happy to collect your money, but when you want out of their service they will give you a run around and all the excuse that you cannot cancel them. Good luck to those who wants to use them.
