The portable multi-channel 2.4 GHz wireless video surveillance receiver is a standalone pocket monitor for the rapid reception, display, and monitoring of audio and video signals from 2.4 GHz analog wireless cameras. The device features a 2.5-inch color TFT LCD screen, a built-in speaker, a headphone jack, and an analog audio/video output (A/V Out) for connection to an external TV, DVR, or larger monitor. The receiver supports the selection of 4 fixed radio channels by pressing a single BAND button, featuring LED indication for the active channel and battery status, making it a convenient solution for mobile site monitoring, baby monitors, or field testing of video cameras.
