Each modified smartphone operates like a regular Android device, maintaining all native apps, connectivity, and system updates, while integrating a custom covert recording system. Record hours of continuous footage in Full HD, store it securely, or stream live when using the optional 4G module.
 
 
Smarter Use of Covert Spyphones
You can set up easily controlled, real-world test scenarios from mock interviews and entrance surveillance to recording in crowded or noisy environments. Each model offers a balance of covert functionality and practicality, used in both personal and professional contexts. A good idea is to manage your workflow by combining your covert smartphone with a button camera with a DVR for additional camera angles and higher operational flexibility while in the field.
