Things to Consider Before Buying a WiFi Door Sensor

Smart Features

The true smart sensor integrates with other smart home devices. Buy a sensor that sends alert to your mobile and can be controlled from anywhere. Some other useful smart automation features like switching on/off light when you open or close the door.

It should be compatible with smart assistants like Alexa, Google Assistant etc. 

Ease of Installation & Use

Most of the customers prefer contact sensors that are easy to install or DIY install. Most sensors are adhesive based and can be stick easily on the door or window frame.

The smart sensor should be easily installable and work on other options like cabinets, drawers, safes etc.

Battery Life

The sensor tends to consume lot of battery but lately the newer model are frugal in power consumption. Choose new generation smart wifi sensor with good battery life. Changing batteries every 6 months can be a pain.

Connectivity

In our reviews and survey over a while, we noticed lot of smart sensors missed sending alerts as they intermittently lost connection with the hub. The poor wifi range is generally the issue and may require wifi extenders in some sensors.

Types of window and door sensors

There are three basic types of window and door sensors and one specialized type of sensor. Understanding the type of sensor will help you choose the best wifi door sensor for your needs.

Surface-mounted Sensor

Surface mounted sensors are most common and affordable options for door and windows. These includes magnets which forms the core component of the sensor.

Recessed Sensor

As the name suggests, these are fixed into the surface of the door or windows. They are quite accurate as a sensor and are not as visible as other types of sensors. Installation is bit tedious and requires expertise.

Vanishing Sensor

These are the minimal and thin in design. Vanishing sensors are best option if you are looking for a sensor that just blends with the surface and is not easily visible.

Vented Window Sensor

Vented window sensor includes two magnets and allow the window to be open to some extent without triggering the alert. But if the window is opened further it will set the alarm ringing.
