BTech Smartphone Solutions Spyphone DVR with additional Button Camera.

This fully functional refurbished Android Smartphone comes with a lower price point than our standard Spy Phones. You can get this professional piece of equipment, together with the external button camera, for a fraction of the price when compared to the most known brand phones.

Compared to the Samsung S7 and Samsung S9 Plus phones, this Spy phone records via the button camera, or the front/back camera of the smartphone itself. 
Usually, when you open any Camera App, in order to record, it has to be open and running in the front. This App makes it possible, for the front/back/or button camera to record covertly, with the App running in the background. 
It is equipped with the same covert App as our mentioned Samsung models, which can fully function in the background while you are using any other App on the phone. The phone can be locked, you can take or place calls, and the covert app will keep recording. 
The App comes already installed on the spy phone and can start the covert recording immediately. The extensive settings menu will allow you to set the exact recording parameters you need for your fieldwork. 
This well-rounded and easy-to-carry spy phone is ideal for any covert work, be it indoors or outdoors. It is easy to use and carry around unnoticed. If connected to the additional external button camera, it will be easily body-worn, as it is smaller and narrower than the standard body-worn DVRs.

Spy Phone App Main Features:

  • App operates fully in the Background
  • The covert spy phone can be locked while the recording is going on in the background
  • Date/Timestamp available
  • Use any App while covert recording is active
  • Answer and place calls while App is recording
  • Compatible with Google Play
  • Angle of view can be adjusted to 0 / 90 / 180 and 360 degrees

Samsung Spy Phone App Feature Focus:

Real Smartphone that works as a covert Spy Phone

This is a regular Smartphone with all the features we are now used to on Android phones and Apps. You can use this phone regularly, as a private or work phone, and also make the needed field recordings with it.

Covert App that can run in the background while you are using your phone

While you are running the covert App that makes the video recordings, you can use your phone normally; answer calls, place calls, play games, send emails, etc. This is convenient and provides an additional layer of safety. It is extremely hard to be suspicious of covert recording if someone is just placing a game on their phone. Furthermore, the phone will continue to record even if the screen is locked and it is just placed on the table. 

Extended Video and Audio settings 

You can set the camera selection, the audio parameters can be adjusted precisely. The resolution and frame rate can be also adjusted to suit specific work conditions and you can choose between audio-video and snapshot selection. 
The App is the same for all our Spy Phone models:
