170 Degree Mini FPV AV Drone Camera 600TVL with Audio (Mini 200/250/300)

170 Degree Mini FPV AV Drone Camera 600TVL with Audio (Mini 200/250/300)

This is a 170-degree wide-angle mini FPV camera with 600TVL resolution and audio, sold for Mini 200, 250 and 300 quadcopters.

The listing says it supports both PAL (for sharper text display) and NTSC (for smoother playback) video formats and captures at 1280 x 960 resolution at about 50fps.

It is compact, lightweight and works well in low light, and it runs on 3.7 to 5V at about 100mA, which suits FPV drone builds.

Key features

• 170 degree wide angle: 600TVL resolution with audio.

• For Mini 200, 250 and 300 drones: a common FPV size range.

• PAL and NTSC: PAL for sharper text and NTSC for smoother playback.

• 1280x960 at about 50fps: as listed.

• Low-light capable: compact and light.

• 3.7-5V input: about 100mA.

How an analog FPV camera works

An analog FPV camera sends a live composite video signal to the video transmitter on the drone. The image sensor turns light into an electrical signal, the camera processes it and outputs a video signal that the transmitter sends to your goggles. TVL (television lines) is a measure of horizontal resolution, and a bigger sensor usually collects more light, which helps in dim conditions.

The lens sets the field of view: a wider angle shows more of the scene and exaggerates the sense of speed, while a narrower angle shows a more natural picture. Features such as WDR (wide dynamic range) balance very bright and dark areas, DNR reduces noise and auto gain control adjusts the picture as the light changes. Low latency matters, because delay between what the camera sees and what you see makes flying harder.

Set the video standard (PAL or NTSC) to match your goggles, power the camera within its rated voltage range and mount it firmly so vibration does not blur the image. Tilt the camera up for fast, forward-pitched flying. Keep the lens clean and use a lens protector or ND filter where suitable.
