Now you can have a Samsung S9 Plus, use it as a regular phone, and work covertly when needed. The phone is an original smartphone, so you can use it with all the functionalities, features, and benefits of a real phone. The covert App on the phone comes pre-installed and ready to use. It is hidden in a very popular application, that does not raise any suspicion. We have avoided showing the App, to keep it as covert as possible.

The App will also continue to record in the background if the phone's screen lock is on, and it is just laying around on the table. If you need to stand up or get going, the lens position makes it possible to continue recording, and get the footage you need.

This has multiple benefits when it comes to law-enforcement professionals and tracking their agents on the field.
