- The transmitter and receiver can be used in the same channel, or one to several usage in the same channel (that is, one transmitter sends signals, several receivers receive signals, the receipt is synchronous and accurate, equivalent to wire video distributing machine) or several to several usage (that is, each transmitter takes a channel, slightly adjusting frequency of receiver to select video and audio transmission of another channel, without mutual disturbance). 
- The video signals received are clear, stable and vivid in color, with good sound effect. 
- Video transmission in NTSC or PAL. 
- AV output terminal of receiver can be connected with equipment with video and audio input, for example: recorder. 
-The AV input terminal of receiver can be connected with equipment with video and audio output, for example, VCD, DVD, convenient for installation and commission. 
- Connection terminal: AV output jack, earphone output jack, power input jack, AV IN jack. 
-This unit uses Li-ion battery, convenient for tour. 
-This unit is manufactured with international new integrated circuit and TFT colorful liquid crystal display technology. It has the following features: low power consumption, stable performance, no X-ray radiation. 
- It is suitable for monitor, supervision, investigation, obtaining evidence, installation, commissioning and other professional usages, and can meet high-level professional safety demands. 
- It is attractive for powerful function, simple operation, small volume, wireless signal transmission. 
- It can be matched with mini type colorful wireless camera for hidden usages. Its signal can penetrate wall and realize synchronization of picture and sound at the site.
