⚙️ Hardware Setup, Adjustments & FAQs

❓ How to select the camera's technology mode (HD-TVI, HD-CVI, AHD, Analog)? cfg_01
Typically, there is a small button or a jumper on the camera body (near the connectors) that allows switching between modes. Consult your DVR/NVR manual to determine which technology it supports and select the corresponding mode on the camera. If there is no button, the camera may be auto-detecting or already configured to a default setting.
