Montavue MTDB2140 Wi-Fi Doorbell Camera with 1080P HD Resolution, 64GB SD Card, Night Vision, 2-Way Audio and PIR Motion Detection

Not all doorbell cameras are created equal. The Montavue MTDB2140 doorbell camera features the industry-leading 2MP HD image sensor.  This gives you an HD image at an impressive 140° FOV.  This Montavue doorbell camera also features a built-in Audio mic and speaker, allowing you to hear and speak to the person at your door with your phone or tablet. You will also get 20FPS video recording at 2MP 1080P HD resolution and smart motion alerts with PIR motion detection.  This camera will work seamlessly with our MontavueGo app, allowing you to communicate with whoever rings your doorbell remotely.  Furthermore, you can add the camera to your Montavue NVR so you can constantly record the stream (motion events will still be stored on the SD card).  If you use it as a stand alone camera, you will use the included 64GB SD card for motion recordings.  Unlike much of our competition there are no monthly fees or cloud subscriptions needed.

Compatible with MontavueGO – Our free mobile viewing app for PC/Mac and Android/Apple

With MontavueGO you can access and control your cameras and surveillance system from around the world with the power of internet and by using our incredibly easy to use application on your mobile device or computer. When using your mobile device simply download the MontavueGO app and scan the QR code on your camera and/or NVR in order to sync your system to your phone. Now you can view and control your cameras from anywhere. Live viewing and past recordings are only the start, there are an abundant amount of features, one that we love is push notifications. Set the camera to motion detect and when something moves in the area you designate the application will send a push notification to your phone.  With the doorbell camera, when someone rings the doorbell button or triggers motion detection your phone will alert you and you can see and speak to them from anywhere.  The included 64GB SD card will record all PIR motion events and allow you to view them on your phone or tablet, so even if you missed the call you will still know what happened.  This also means that no cloud subscription is required.

Advanced PIR Motion Detection

With each Montavue network doorbell camera you have the ability to create distinct PIR (passive infrared) motion detection zones. This gives you control over the alerts you receive on your phone or tablet. This advanced feature from Montavue allows you to only view and record the things that matter most. Each individual zone has its own distance settings, this gives you the power to fine-tune the zones to your exact liking and minimize false notifications from pets, vehicles, etc.


Two-way Bidirectional Talk

The Montavue MTDB2140 doorbell camera will allow 2-way audio, both locally and remotely.  This means that when someone presses the ring button on the doorbell your phone will start ringing, even if you are away from home.  When you answer you will have a video and audio feed of them and they will be able to hear you.  The same applies if they trigger the motion detection, you can enable two way audio on your phone and see and speak to whoever is there.  This provides an extra layer of security so you will know who is at your doorstep without having to unlock your door.  With the massive increase in "porch pirates" these days it never hurts to take extra precautions to protect you home and belongings.

Wide Field of View

When it comes to monitoring large areas, the Montavue MTDB2140 doorbell camera has you covered with a fixed lens field of view of 140°.  One thing to check to make sure you are comparing apples to apples between cameras, is the difference between a horizontal and diagonal field of view. Make sure that both are horizontal or diagonal.
