Great bunch of people. Extremely helpful and friendly. Called on a Monday, new cameras installed on Tuesday. They even came back on Wednesday to make sure we were happy with the function, placement and we were able to understand how to operate. Thank You Patrick and Tim you guys are terrific.

Stefanie Chambers

Sentry Surveillance has been great. The system is very high quality and Mark Publicover was very knowledgeable and professional. I have been very impressed with the customer service also. The video quality is better than I expected. The night video is of very impressive quality even in complete darkness. The system functions very well

Eric Holloway

From the sales process to the installation, Sentry has done a great job. I would like to give a extra thanks to Will for the awesome job on my installation. He explained the functions of the system and made sure I could work the phone apps as well. Thanks Sentry Surveillance
