KC03 2.8MM 120 Degree 800TVL NTSC Switchable Camera with 600mW FPV Transmitter

The product is very good the camera quality shocked me because I already had a name brand camera but this one seemed to outperform it by a pretty noticeable amount.

TL;DR: Setup worked when I powered it with 12 Volts (minimum for camera seems to be 5, minimum for VTX seems to be 7)There was I believe one or two people in the comments complaining about the LEDs on the VTX not turning on and there being an annoying noise. I had this same issue too when I supplied power via a 9V battery. The VTX didn't seem to properly function and I couldn't change channels and bands... HOWEVERDuring my troubleshooting process I questioned whether it was an issue regarding sufficient voltage. This time I supplied the VTX/Camera with 12V. It worked. The LEDs on the VTX turned on and I configured the frequency. The moment I turned on my FPV monitor the setup worked.

This needs at least 7v not 5v. Will not run off of my pwm receiver. I had to add an extra 2s lipo to power it up.

RP-SMA Antenna! Would have been nice to see that in the picture before I bought the wrong type. Seems to work ok so far, doesn't get too warm as long as you have some airflow to it. Camera connector to board harness is NOT the same on both sides (socket has beveled corners), but will connect if you force it a little. Seems to sip power nicely on a 2S. Difficult to find an elegant way to mount it, there are an offset pair of (3mm?) holes, but the board is double-sided so you need standoffs. No rear cover on the camera, minus 2 stars for that and the other small issues. You get what you pay for, seems to work for what it is, cheap way to see if it's something you want to get into.

In fact, I didn't get better performance from higher-price analog models that I tried.Just be aware that the included antenna is dipole -- so for best performance on freestyle quads (or indoors) you may want to swap it for a circular polarization antenna.

Transmitter seems to work (but gets hot) and as soon as I plug the camera in, the lcd numbers/letters on the transmitter turn off and nothing works. I am guessing a short in the camera but who knows? I should have known better to think something like this would work out of the box with no issues. Sending it back and going to GetFPV for a more reliable set up.Update: I think I have narrowed down the issues. The transmitter needs 12v and about 1 amp of power. ALSO, the camera although they give you a 5v out to run it, also needs its own 12v supply to run as well. I still haven’t gotten it all to run for a long duration yet but things are improving slightly.

It works great love it

I ordered the KC03 2.8MM 120 Degree 800TVL NTSC Switchable Camera with 600mW FPV Transmitter however received the FX2 Dominator video transmitter with no camera.
