I bought the AVF Selfie Remote from Viewnet in Low Yat in Kuala Lumpur late last year for RM19.00 (at the current exchange rate, it is equivalent to SGD7++) in the bargain bin. It is a simple device that uses bluetooth to pair with your Android or iPhone phone and uses the built-in camera app. In cases where it is not able to use the built-in camera app, it would need to use the Camera 360 app which is free. This would complement with a selfie monopod, which is the rage at the moment.
• Communication: Bluetooth Version 3.0
• Transmit frequency: 2.4GHz-2.4835GHz
• Communication distance: 10M(30ft)
• Battery life: CR2032 x 1 cell (about 6 months life under working in 10 times a day)
• Dimension: 50 x 33 x 10.5 mm
• Weight : about 9g
Most of the iDevices would need to use the Camera 360 app but Android devices can use the existing in-built camera app.
