At Sentinel Security Systems, our goal is to create a system that's perfect for your property. First, we perform a walkthrough of your building to determine your needs. We then present you with an on-site proposal and detailed estimate. Depending on your needs, we may propose a wired, wireless, or hybrid setup. If you don't have a reliable landline or internet connection, we may suggest a radio-based system to ensure the lines of communication are always open. Some clients want to protect every window and door; others only want ground-level protection. Whatever type of system you want, we provide a tailor-made solution that will provide you peace of mind.

Total Installation & Maintenance

As security system specialists, we offer complete installation services. Once the system has been installed, we thoroughly test it to ensure it is communicating with the monitoring system and functioning properly. Our team also provides ongoing maintenance and updates. If you change phone companies, replace a window or door, need a new battery backup, or have any problems at all with your system, contact us. We'll come to your location to resolve the issue as soon as possible. Same-day or next-day service is available.
