I have been using Sentry for a few years and also when I moved location. I’ve never had any problems. Tech support is always available to help me if I do run into any issues (which is seldom) and Brian has great customer service. Lee was a great install technician. Everyone at Sentry from answering the phones to service is a pleasure to work with. I’m so glad I found them! Not only is my business secure, I can rest assured they will assist me and provide me great security.

We have numerous Security Projects at various facilities throughout NYC and Long Island, Sentry provides excellent support for us.

I love Brian and the Sentry team. If you need cameras, fiber and copper structured cabling, door access control or alarms youve found the right company. They are professionable, trustworthy and reliable.

Brian and his team did a full wiring job for our new office. They were professional, neat, and delivered as promised. I would highly recommend Sentry.

If you are looking for a full service security company, do not look any further. Sentry is your answer! They are professional, efficient, fair and they do beautiful work. I would highly recommend them.

Just had them install camera system yesterday They did what they said they would, in a neat and efficient way, and they made adjustments as I requested, the tech support the day after was superb. So far so good!

The entire team is very responsive and professional. My answers and troubles have always been resolved extremely quickly!

Sentry as a Company has been top notch. They are very attentive to all of my security and communication needs. They always go above and beyond in order to make sure the job comes out right. I highly recommend there services.

Sentry is definitely a cut above the rest. They go above and beyond to provide excellent customer service. They are a big company but unlike others still provide that warm treatment of a small company. Brian and Alex are true gentlemen. I would recommend them to anyone looking for a cutting edge security system.

Very reliable company with best technical team. They install their system in all 5 of our indikitch restaurants in NYC. I would say they are available 24/7 for any after install or maintenance issues.Sentry is a great option when it comes to true value with its vast number of alarm system options. We’re really happy with Sentry in focus and willingness to adapt to the needs of its clients.

STAY AWAY !! Made appointment with this guy Brian for a security system for my house. Day of appointment NO SHOW, NO CALL. Called next day for explanation, no return call ?? If you cant show for appointment how can you protect my house.?? BIG WARNING SIGH !!

We use sentry communication for our surveillance system.Brian is very responsive the is always there when you need an upgrade, adding new equipment or professional advise @ no chargeThe technical support team is very knowledgable ready to assist you and whenever you need it.

Top notch company with pure professionalism. They do a great job with alarms, cameras and AV. I have used them for years and they have always been attentive, whether its a service call or installation. I would HIGHLY RECOMMEND!!

Brian and his crew were amazing. They hung a tv. They installed an alarm. They installed cameras in and out of the house. The installers were fabulous. They showed me how to use everything they installed and even helped me set up the web based and app based services. I would recommend them to anyone.

I wish I used this company years ago. I went with a cheaper system and it was a mistake for many reasons. Brian and his team have installed 16 camera systems at two of my locations. Customer support is fantastic, system is intuitive and crystal clear. I will never trust another company with my security systems.

These guys handle all my security and camera needs. Very reliable and prices are always reasonable. Their customer Service after job is complete is the best!!

Thank you to brian and the sentry team for helping with our security camera setup. Neal and his crew made sure everything was exactly as we wanted---even offering his expert opinion to ensure all areas of our office is secure.Feel free to use me as a reference anytime.Thank you sentry!

Excellent company! This company is professional and their support is excellent. I would only recommend using this company for installing a camera system . Sales, Support, Service, Installation 5 Stars !

Signed with Brian for a security system, Hyme came a few weeks later to install the cameras. From start to finish they did a great job. The cameras have helped us in a few situations already. Great company to do business with.

Very Happy Customer right here! After doing our research, we decided to have Sentry Communications & Security install our home security system, and we couldnt have been more pleased at the service we received. We were explained all of our options and Brian made sure that we had just what we needed. The man who installed our system did so with care and explained every detail to us and he went along. We were very impressed with the entire experience. Would definitely recommend!!!

Sentry setup all of our security needs. They are fast and attentive and have great rates. I would recommend them to anyone.

Great company and even better service and support. I chose the right company to protect my family and I. I strongly recommend them to all.

Sentry security installed my alarm system and they were excellent. I highly recommend them to anyone looking for an alarm system.

Thank you sentry communications & security for my camera and access system. The system has worked out great and your service has been top notch.

Great company and the owner came and explained all to me and the surveillance system and fire alarm system is working out great.

THEY DO NOT DESERVE 1 star, it is only way I can post by selecting 1 star/ These guys continually harass us by bombarding us with their incessant phone calls being placed over our objections voiced.. REMOVE US FROM YOUR PHONE CALL LIST, WE ARE NOT INTERESTED IN YOUR SERVICE. If we wanted to use your service, by now we already would have called you. DO NOT CALL POISON IVY REMOVAL, REMOVE US FROM YOUR LIST.

Very professional service. Had a great experience.

I was very unhappy with the service I received from this company.Once they install your system, the service goes downhill. I was talked into buying a security system and doing a finance program. When all is said and done, this system costed me over $4k. I was unable to afford their yearly service plan, which is over $500, and without it, they will not help you even though you purchased it from them it from them. I called recently because my DVR is not recording any longer, spoke to the service Manager who was not very nice and totaly unhelpfull. He tried to tell me a new 4 channel dvr would cost me $2000. I am not a tech guy but I am not an idiot either. Then he said that he would send a technician out to replace the hard drive (which is less than 3 years old and I am still paying of) but it would cost $180 for the guy to come for the first hour plus $450 for the hard drive. He also reminded me that had I paid the service plan (that I could not afford) it would have been less expensive. After researching I found similar four camera systems with a DVR for $400 to $700 dollars. BOY WAS I DUPED !I then spoke to an security tech guy who for $250 would install the new system.As a small busness owner I understand how important honesty is in busness. This was not a good move for me as a new busness but all I can do know is let others know to be aware of what you are getting into.

Awesome work.

Good alarm system
