Using your Foxeer Micro Razer camera is easy. First, decide whether you want to use PAL or NTSC mode according to your region. Then, connect it to your device. You'll notice the clear image right away thanks to the 1200TVL resolution and 1.8mm lens. When using, keep it away from extreme heat or cold. For maintenance, use a soft, dry cloth to clean the lens regularly. Don't expose it to water or other liquids. This will help keep your camera in great shape for a long time.
