Frequently Asked Questions - BNC-50 FIRST ALERT
How do I connect the BNC-50 camera to a DVR?
Use a high-quality BNC cable to connect the camera's BNC output to the corresponding BNC input on your DVR. Make sure the power adapter is connected and the camera receives 12V DC.
Can the BNC-50 be used outdoors?
Yes, it has an IP66 weatherproof rating, so it can withstand rain, snow, and dust. Ensure the connections are properly sealed to prevent moisture ingress.
What is the night vision range of this camera?
The BNC-50 features 12 IR LEDs that provide clear black-and-white images up to about 20 meters in complete darkness.
How do I change between NTSC and PAL?
Open the camera housing to access the CVBS/NTSC/PAL switch located on the circuit board. Set it to the desired standard, then close the housing securely.
Why is the video output black and white?
The camera switches to black-and-white mode in low light conditions. This is normal and enhances sensitivity. If it stays monochrome during daylight, check the day/night selector setting.
Can I use this camera with a wireless system?
No, the BNC-50 is a wired analog camera that requires a BNC cable and power. If you need wireless, you will need a separate video transmitter.
How do I clean the camera lens?
Gently wipe the lens with a soft microfibre cloth. Do not use harsh chemicals or abrasive materials. For the housing, use a damp cloth and dry it completely.
Does the camera support audio recording?
No, the BNC-50 is video-only. It has no built-in microphone or audio output. If you need audio, consider using a separate microphone with your DVR.
What is the optimal mounting height?
We recommend mounting the camera at a height of 3 to 5 meters to get a good viewing angle while avoiding tampering. Adjust the bracket to aim the camera at the target area.
My camera has no picture. What should I check?
First, verify the power supply and that the LED is on. Next, inspect the BNC cable connections for any loose or damaged pins. Also check the DVR's input channel and ensure it is set to the correct mode (AHD/TVI/CVI/CVBS). If the camera still shows no image, test with a known-good monitor.
