Mini Wireless Screen

2-Channel 7" LCD Screen

TviBell carries a mini video receiver as a separate piece which will remain behind the scene. That piece directly plugs into the TV or the LCD Screen. The external TviBell box has a standard transmission range of 100 ft. line of sight. The TviBell Q-4T model features 300 ft of transmission range as well as enhanced video quality for upscale residential or commercial applications.

To use TviBell for two doors, i.e. front and back door, you ought to employ a Q-4a model and a Q-4b model. Both work on different radio frequencies so they don't interfere with each other. Your TV must have at least two yellow video RCA line jacks or use our mini 2-channel 7" TFT LCD Screen.

TviBell Q-4sa comes packaged with a mini handheld 2.5" LCD screen. If you want a dedicated screen for your application instead of a TV set, you may use the 2.5" LCD screen or a 7" LCD screen, single channel for one door or double channel for two doors.

Finally a wired version of TviBell is also available with Model No Q-4w. It delivers extremely crisp color pictures. It is strongly recommended for commercial applications, and any application where the wireless will be deficient due to involved distance or cross obstacles like metal framing of a building or heavy concrete walling.
