Wireless Video Transmitter

[Dodol]

Hi,
I am looking to buy or rent a wireless audio video transmitter and receiver.
I want the transmitter to have a built-in battery so I dont have to carry around a 12 volt battery.
I bought a wireless transmitter and receiver a week ago. Brand: Hamy KY-1000. It has a built-in battery and a range up to 500 meters. Problem is when I did a test shooting, the receiving picture is not good. The video is jerky.
I need the video to be good quality coz I will be doing live feed to the big screen and I need to move around.

Any of you guys have a suggestion?

Thanks.
