TA-505 is a multi-functional visual 2.4G digital wireless transceiver walkie talkie which is is produced by our own R&D team,used the latest wirelesss speech image transceiver module CW-WMV-001,equiped with the latest RF chipHigh-performance ARM processor chip Micro digital camera, and used industrial-grade design criteria to build a multi-functional wireless video intercom product. It consists of two parts: headphone and handset. Headphone is equipped with wireless transceiver modulemicro-cameraearphone and other capture and playback devices. It collects speech signal through earphoneimage signal through camera, and transfer out to handset, minwhile receive the speech signal from handset and play out through earphone. Similarly, the handset is equipped with wireless transceiver module, 2.4 TFT LCD, earphone and other capture and playback devices. It receives speech image data from headphone and play out through earphone and LCD, at the same time, speech signal collected through the headset wirelessly transmitted to the headphone. With small size light weight easy to operate features, it can be applied to any one-way short-range wireless audio and video data applications.
