Causes of Image Darkening

Several factors can contribute to image darkening in Hikvision security cameras:
Incorrect Lighting Conditions: Ensure the camera is installed in an adequately lit area. Insufficient lighting can result in underexposed images.

Faulty Sensor: A defective image sensor can compromise the camera's ability to capture light. Contact a qualified technician or Hikvision support for assistance.
Power Issues: Insufficient power supply can cause the camera to malfunction, resulting in image darkening. Check the power adapter and connections for any loose or damaged components.
Outdated Firmware: Outdated firmware may contain bugs or compatibility issues that affect the camera's image processing. Upgrade the camera's firmware to the latest version.
