Hidden cameras with remote alerts and notifications typically use a Wi-Fi or cellular connection to send alerts and notifications to a user’s smartphone or other device. The camera is typically connected to the internet and can be accessed remotely using an app or web interface. When the camera detects motion or other activity, it sends a notification to the user’s device, typically with a photo snapshot or short video clip of the activity. Some cameras may also include other types of alerts, such as sound detection or facial recognition. This technology allows users to monitor their home or business remotely, providing an added level of security and peace of mind.
