Hollyland Mars300 300ft Image Wireless HD Video Transmission System 1080P Dual HDMI Transmitter & Receiver for Camera Monitor

The unit comes with everything you need to set up a wireless HDMI signal from a camera or other device. I haven't been able to test the limit of the range, but I have been able to use it indoors through multiple walls with lots of RF around (600 MHz all the way to 6GHz).

I read many reviews about the Hollyland Mars 300, and can confirm that all is well despite the much lower price than other systems I've used from Swit and Paralinx. The range and ability to work through walls was impressive compared with Swit etc., the latter also being good. The units are light and when tested for 2 hours using batteries they only got warm (not hot). The only slight compromise over the more expensive systems was the latency which was a little higher. For example, if the video signal is sent via these units and the audio is connected directly via cable, there is a slight loss of lip sync, perhaps about 1/10 sec (though I didn't measure it). The Swit and Paralinx gave no appreciable lip sync error in the same setup. But if you embed the audio with the video and send both via the Mars then lip sync won't be a problem. If used to help with focus pulling the latency shouldn't be an issue. So overall, very impressive devices.

Using this for a multi-cam event and needed a camera man on foot. It's a great product for the price. There's a little delay, maybe 1/10 of a second but can work with it.Would want to get a small display to see which channel the transmitter/receiver is on as when we tried using 2 of these, it got kind of a bit confusing at start but managed to make it both work.Needed to buy Sony NP-F batteries for the transmitter.Overall very good build and very good quality for the price.

great price.

En general funcionan correctamente a una distancia algo menor de la recomendada.El principal fallo es no disponer de una pantalla que indique ni el nivel de batería ni el canal de frecuencia usado por transmisor ni receptor. Un auténtico dolor de cabeza en ocasiones.Por lo demás, advertir que vienen con enchufe americano, por lo que conviene hacerse con un adaptador para poder enchufarlos a corriente.

Transmite VIDEO y AUDIO a máxima calidad, lo he usado en retransmisiones en directo y fantástico resultado.incluso con paredes por el medio.
