How to use

Mount the camera on a stable surface using appropriate fasteners and aim the turret to cover the desired area. Connect to power and network according to your installation type (PoE or separate power supply as applicable). Configure network settings, time synchronization and recording preferences via the camera’s web interface or compatible NVR. Enable AcuSense detection rules and adjust sensitivity and detection zones to match the monitored environment. Insert a microSD card for onboard recording if local storage is required and format it through the camera’s settings.

Recommendations

Position the camera to avoid direct pointing at intense light sources to reduce glare and false detections. For best detection accuracy with AcuSense, define clear detection zones and test alert settings during different times of day. Use a weatherproof cable gland and proper sealing for outdoor cable entries, and choose the 2.8 mm lens for wider coverage or the 4 mm lens for more focused detail at longer distances.
