Recommendations

Place the camera at a height and angle that avoids direct sunlight and minimizes obstructions for the 85° horizontal field of view. Use a high‑quality TF card (up to 256 GB) formatted in the app for reliable local recording, and enable cloud backup if continuous off‑site storage is required. Ensure the camera is connected to a stable 2.4 GHz Wi‑Fi network and keep firmware and app updated for best performance.
