This wireless indoor camera is built from alumunium die cast material. Its dimension is quite small, only 3 x 3.5 cm with a 4 mm lens. The maximum range of signal transmission from the camera (with built-in transmitter) to the receiver is about 20 metres. Utilizing radio wave 1.2 GHz, the signal transmitted can pass through walls and cannot be catched by television set without using a receiver.

However, one of the weaknesses of this wireless security camera is it can only perform well in bright room. As a note, this camera has minimum illumination 1 lux. Another weakness, with CMOS sensor the images captured are not clear enough. However the price is quite cheap, about US$ 40, including a receiver, a 9 V battery and an adaptor. Moreover, this mini security camera also provides a built-in microphone that might be useful in some situations.
