Window and Door Contacts

Did you know, according to the FBI over 50% of burglars enter your front or back door to gain access? That’s why our door and windows sensors are one of the most important security sensors on a security system. Our sensors monitor the opening and closings of a door or window and trigger an alarm when your system is armed in the event of an unwanted intruder.

Door and Window Chime 

When your alarm system is off and your door or window is opened, our smart security system with window and door contacts can sound a door chime so you know a door or window has been opened. Most of our systems have multiple chime selection to help differentiate which door was opened. The chime feature may even be turned off in the event your kids are running in and out of the doors all day. 

Delay Doors and Windows 

When the door is set to delay mode when the alarm system is armed there is a predetermined time that you have to enter the code into the keypad before the alarm goes off.  This time is usually set from 10 to 

60 seconds but can be set at other increments per request. This allows someone to enter the house, while armed in stay and disarm the system. This is very practical if someone is home and wants the protection that the alarm system gives, but is waiting for someone else to come home. The window and door contacts delay may be temporarily removed during arming modes should you like those doors “instantly” to activate the alarm upon an opening. 

Instant Perimeter Doors / Windows 

Our instant doors and windows are used when you do not expect anyone to come in through that entry point when the system is armed. If any door, or window is opened, the alarm will be tripped. This feature is used when you don’t want to give an intruder 10 to 60 seconds to enter the house prior to the alarm triggering authorities. 

Expertly installed-Reduce False Alarms 

Our professionally installed security sensors are much better than the DYI installs. We do our best to conceal the contact inside of a door opening vs. the fast and easy “peel and stick” sensors. Our professionals know how to install these contacts to help reduce those annoying false alarms, which could result in local police department fines and slower response times in the future. 

Supervised Wireless Sensors Our smart sensors will monitor itself to help ensure its operation. In the event a person tampers with the wireless sensors it will send a notification to let you know something it not right. 

Battery Life 

We know constantly changing batteries is a nuisance. That’s why we only install wireless devices that are expected to have a long battery life. Our system will monitor the battery levels and notify you when it’s time to change the batteries, allowing you time to change them out prior to them going dead.

Unexpected Activity Alerts 

Most security systems stop paying attention once they’re disarmed. We help you stay on guard 24/7. Your system learns your home’s activity patterns and alerts you to non-routine events with unexpected activity alerts even when your system is disarmed.
