Using a hidden camera with a mobile app does not require any additional fees in most cases. However, it is important to note that some apps may have premium features or subscriptions that may require payment. Additionally, there may be data usage fees associated with streaming video from the camera to your mobile device if you are not using Wi-Fi. It is always a good idea to check the app’s terms and conditions and data usage policies to avoid any unexpected charges.
It is also important to note that some cameras with mobile apps may require a separate purchase or subscription for cloud storage to store recorded video footage. This is especially important if you want to keep recordings for an extended period of time or if the camera does not have a built-in memory card slot. Be sure to check the product details and specifications before purchasing to ensure that you are aware of any additional fees or requirements.
