Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Modern houses require modern security solutions. A simple lock and key won’t suffice anymore.

When it comes to home security, one thinks of securing only the door while leaving the window wide open for the burglars. According to Safewise, over 3,000 burglaries happen in the US per day and mainly during the day.

This means one has to be vigilant and employ a proactive approach rather than a reactive one. It is essential to understand that security should continually be updated and upgraded. It is high time for people not to live at the mercy of bolts, hinges, and handles. It’s time to turn to more ingenious security solutions like door alarm sensors and window sensors.


Door and window sensors are essentially the same things. These are also called contact sensors. They generally get triggered when someone opens a door or window without authorization. There are two types of door alarm sensors.

  • Door-open alarm – It is activated when an intruder holds the door open for a certain period.
  • Door-forced-open alarm– It is activated when someone opens the door by force.

Window sensors are, commonly, of four types. These include wireless surface-mounted, hardwired surface-mounted, wireless recessed, and hardwired recessed. The Surface-mounted window sensors are made for the exterior window frames and are visible, while the recessed sensors are invisible because they are hidden inside the window.

Purpose of Alarm
  • Ensuring better security for loved ones remains the primary motive for installing door or window sensor alarms, especially for families with kids and elders. One can set the alarm to notify them anytime the windows and doors get opened.
  • Keep criminals at bay with a home security system that includes integration of door and window sensor alarms and provides a monitoring feature. This will help in contacting the authorities, who will check up on the person via phone call to make sure if people inside are safe or not.
  • Peace of mind is extremely valuable. If people install door alarm sensors and window sensors, they will feel more safe and secure in their home. They will worry less when they leave home for work or vacation.
  • Wireless door alarm sensors can be used in different ways. For example, to turn lights on when a door opens, keep kids out of the medicine cupboard, and trigger smart lights, among the above reasons.

Uses and features of these devices

Alert Options

Entrances and exits are the vulnerable part of any home. These are the areas where burglars try to break in. If the door or window has sensor alarms, criminals will find it challenging to get in. This sensor gets triggered when someone tries to open the door or window, and a vibrating bell will resound in the house. The sound can either be a gentle chime or a blasting alarm, which can scare away the burglar.


The best security sensors allow the device to connect to the centrally monitored security. As some brands enable the person to operate their door, they can lock and unlock the door remotely via smartphone. One can even monitor the activity remotely via a smartphone app or other security devices using a Z-wave hub. If someone opens the door, they will get notified on the phone via an app and can also see who is at the door via a security camera.

Rig them

One can also rig the door sensors, like using them on cabinet doors for keeping the kids away from liquor, patio doors for keeping the kids away from the pool, and even office doors for maintaining privacy. People can also use them for their safe, mailboxes, and desk drawers.

Smart Trigger

A person can also place them on valuable items like installing a contact sensor on a TV or a piece of furniture sitting outside the home. One can use it as a smart trigger, such as installing a contact sensor on a closet door that triggers the light on when one opens the closet door. Similarly, when someone showers, it triggers the bathroom fan that draws the moisture away.


For wired sensors, one needs professional installation. However, installation is pretty straightforward for a wireless security system like battery-powered sensors. One can read the DIY instructions to install the device that will tell the person which is the suitable location, set up alarming and disarming behaviors, necessary batteries for the device, and mount the sensors. These are also cost-effective.

Now, let us look at some of the best door alarm sensors and window sensors.
