Dear, we have actively communicated with you and proved that there is no problem with product quality and pictures. Since the environment your customer was in was dark at the time, the camera turned on the night vision mode according to the light adjustment. The effect of shooting during the day is normal. This is confirmed by yourself.If your customers don’t want to switch to black and white mode day or night, choose to turn off night vision mode.Thanks

Thank you very much. We are an ISO9001 factory with own R&D team, and guarantee product quality.
