Frequently Asked Questions

Everything you need to know about Motion Detection Camera - the free, browser-based motion detection app that works on any device.

What is Motion Detection Camera?

Motion Detection Camera is a free web application that transforms any device with a camera and browser into a smart motion detection system. It runs entirely in your browser without requiring any downloads or installations.

Is Motion Detection Camera really free?

Yes, completely free! There are no hidden costs, subscriptions, or premium features. The app works entirely in your browser and all features are available at no charge.

How does motion detection work?

Our app uses advanced frame differencing algorithms to detect movement in your camera's view. When motion exceeds your set sensitivity threshold, it automatically starts recording. You can adjust the sensitivity to avoid false triggers.

Is my video data private and secure?

Absolutely! All video processing happens locally in your browser. No video data is ever uploaded to our servers. Recordings are stored only on your device until you choose to download or delete them.

What devices are compatible?

Motion Detection Camera works on any modern device with a camera and web browser - including iPhones, Android phones, iPads, tablets, laptops, and desktop computers. It supports Chrome, Safari, Firefox, and Edge browsers.

Do I need to install anything?

No installation required! Motion Detection Camera is a Progressive Web App (PWA) that runs entirely in your browser. You can optionally add it to your home screen for quick access, but it's not necessary.

Can I use it offline?

Yes! Once loaded, Motion Detection Camera works offline. The app caches all necessary files, so you can use it without an internet connection. However, you'll need internet to initially load the app.

How long can I record?

Recording duration depends on your device's available storage. You can set automatic recording durations from 10 seconds to 5 minutes per motion event. Manual recording has no time limit beyond your storage capacity.

What video format does it use?

Videos are recorded in WebM format, which is widely compatible and offers good compression. Most modern video players and editing software support WebM files.

Can I record audio too?

Yes! When you first set up the app, you can choose to enable both camera and microphone permissions to record audio along with video.

How do I adjust motion sensitivity?

Open the settings panel and use the sensitivity slider. Lower values (5-20%) work well for detecting large movements, while higher values (30-50%) can detect subtle changes. Adjust based on your environment.

Can I use multiple cameras?

You can switch between front and rear cameras on mobile devices, or between different connected cameras on computers. However, only one camera can be active at a time in a single browser tab.

Where are recordings stored?

Recordings are stored in your browser's local storage (IndexedDB). They remain on your device until you download them to your device's storage or delete them from the gallery.

Is there a mobile app version?

While there's no native app, Motion Detection Camera is a Progressive Web App that works perfectly on mobile browsers. You can add it to your home screen for an app-like experience.

Can it send notifications when motion is detected?

Currently, the app shows visual indicators and logs when motion is detected. Push notifications are on our roadmap for future updates.

How much bandwidth does it use?

Motion Detection Camera uses zero bandwidth for recording since everything happens locally. The only data usage is the initial app load (less than 1MB) and optional analytics if you consent to cookies.

Can I use it for home security?

Yes! Many users repurpose old phones or tablets as security cameras. Just position your device, enable motion detection, and it will automatically record any movement.

What happens if I close the browser?

Recording stops if you close the browser or switch tabs. For continuous monitoring, keep the browser tab open and consider using fullscreen mode to prevent accidental interruptions.

Is the source code available?

Motion Detection Camera is built with modern web technologies. While the code is minified for performance, the app operates transparently in your browser with no hidden functionality.
