Eachine ProDVR review (Part1)

I have received Eachine ProDVR from Banggood for testing/review pruposes. I have started to test it but come up to a problem with ProDVR. I plugged Video In source (camera) and I’ve got no camera picture on the DVR output. Double checked the wirings, but still no camera video on the DVR out! I can get into settings menu, start recording, but without video In. In theory video inputs/outputs should have 75Ohm impedance (resistance to Ground). I have checked the resistance with multimeter and Video In has zero Ohms:

Meanwhile Video Out has 75Ohm resistance as it should be:

Something is not right with unit I have received!
I decided to open and inspect the ProDVR device. After inspection I’ve noticed that some SMD components are misaligned on the board and one component is totally misplaced and probably the reason of the unit failure:

I have informed Banggood about this issue. How I’m waiting for the solution from their side. I cannot finish the review without a working unit.
So much about quality issues.

Eachine ProDVR on board of FPV plane

Eachine ProDVR taken right out of the box. Changed only recording resolution setting from VGA to HD. And it works like a charm.  Some interference lines can be seen on the video, because no LC filter is installed. I was flying wihout OSD, so PAL cropping issue was not a problem this time.
I’m very pleased with the recording quality. Really good DVR for a price.
Plane: DIY ZagNutz flying wing
Cam: Ultra Light Plastic Cased Panasonic CCD 750TVL ( (Out of stock)
VTX: BOSCAM TS351 (Not used in this video as video recorded right from the camera)
