• Improved zoom clarity

The high resolution becomes especially useful when monitoring wide areas because details remain visible even at longer distances.

For example, users can often identify:

• Faces near driveways
• Vehicle models
• Clothing colors
• Package details

This level of clarity is one of the camera’s strongest advantages.

180° Panoramic View

The 180-degree field of view is another major benefit. Instead of installing two separate cameras to monitor a large area, the Duo 3 PoE can often cover everything with one device.

This wide coverage helps reduce blind spots and works especially well for:
