I think there is an option for adding image above video stream in the camera setting. I know Hikvision camera has this function, but I am not sure about Bosch camera.

can u upload a video on youtube and post the link here?

I'm an algorithm designer for CCTV camera and backend device, I hope I can collect user's advice to improve the product.

Thanks for your advices, fenderman~ For parameter settings, there are several automatic choice to change the parameter based on image, like day-mode and night-mode switch, but yeah, like the WDR, there is only turn on and off options now. We will make improvement on this part. For night vision, for the camera which supposes 3D noise reduction, the image quality is good as far as I know, we have also some star-light level camera which has a good perfermance in the evening.

Maybe Hikvision Smart IPC is an solution for you, the smart motion detection function is better than built-in motion detection, reducing false alarm caused and still catching people and cars.

I-frame interval is used for encoding the video stream, which is how long the camera takes one I-frame. I-frame is used in H264 compression.

DS-2CD3332 supports both: 50Hz: 12.5fps (2048 × 1536),25fps (1920 × 1080), 25fps (1280 × 720) 60Hz: 15fps (2048 × 1536),30fps (1920 × 1080), 30fps (1280 × 720)

Joey is correct, when the video is in color mode, it works in daylight-mode, when the video is in black/white mode, it works in night-mode.
