Door and window sensors are perhaps the most important component of a smart, integrated security system. At its most basic, security systems exist mainly to protect a home or business’s points of entry with windows and doors targeted as where an intruder is likely to enter.

Door sensors, also known as entry point sensors, contact sensors, or window sensors make up the backbone of any security system. If a door or window gets opened or breached when the alarm is on, the sensor sends a signal to the main control panel, triggering an alarm.

All doors and windows on the main level of your property are highly vulnerable to a break-in and should all be protected. Unsecured lower-lever entries like basement doors and exterior windows are also easy targets for intruders. Second and third-story windows and doors are less vulnerable because of more difficult accessibility but could still fall prey to a security breach if there are stairs, decks, or access points nearby.

In the past, older door sensors only triggered a bell when someone opened the door. Today, with the advances in technology, these door sensors have evolved into sophisticated monitoring devices that are able to send alerts and notifications automatically.

You can even install glass break sensors to set off your alarm system in the case of a shattered window. If a window is broken, its micro sensor may not trigger an alarm.

The average security system’s door sensor has two parts: a part for the door and the other part on the frame of the door. Almost all the door sensors use a reed switch. When you close the door, it forms an electrical circuit. When the door opens creating a breach the electrical circuit is broken. When the door sensor is activated, and the entry is breached, the security system will trigger an alert.

But what about all those false alarms? False alarms are a reality that has plagued the high-security industry for years and can become dangerous to those assets that monitoring devices have been designed to protect. Too many false alarms can actually decrease critical reaction time as those constantly affected by the alarms start to doubt the validity of the potential threat and downplay the severity of the risk. False alarms are also an added expense, since labor and protective services are dispatched regardless if a true threat has taken place.

The HSI Sensing’s robust Sentinel product line is a group of elite, high-security entry point sensors with a UL 634 Level 2 listing and tout sensors that do not produce false alarms. By using Hall effect technology, HSI Sensing has developed unique door sensors and entry point sensor products that meet all the needs of the high-security industry. Sentinel is an innovative product line intended to be a door contact or entry point sensor useful in a wide range of security applications, for monitoring everything from bank safes to doors in government facilities.

HSI Sensing’s advanced engineering has also eliminated alignment issues at install and can accommodate long term door sagging. Sentinel is also insensitive to vibration – the end-all solution to preventing false alarms.

The best part? Sentinel is ready for use right out-of-the-box. Each Sentinel sensor comes with the sensor, actuator and mounting hardware so you can be up and running in no time.

With the right security system installed, daily operations can continue with the peace of mind knowing that the business, and the business assets are safe and secure.
