Dual-Lens 4MP IP Security Camera with Dual Microphones
Watch two directions through one Ethernet connection.
Monitor two areas from one mounting location with a dual-channel camera that sends two separate 4MP views over one Ethernet cable. Aim the lenses toward different approaches or zones to simplify wiring while keeping useful coverage in both directions.
Choose the view you need
Aim the two 2.8mm lenses independently: one can watch a lobby while the other watches the adjoining corridor, or each can cover a different approach to a building corner. The camera delivers two separate 4MP views over one Ethernet connection. Digital zoom is also available through supported viewing and playback controls, so you can enlarge part of the picture on screen.
See clearly after dark
See beyond what your eyes can see after dark. Built-in infrared night vision reaches up to 100 feet, providing a clear black-and-white view even in complete darkness. Keep watch over entrances, parked vehicles and activity around your home or business after the lights go out.
Audio and professional camera features
Dual built-in microphones; external two-way audio support. Connect compatible external audio equipment to use the supported two-way audio function.
Two adjustable lenses, dual microphones and a metal IP67/IK10 housing make this a practical solution for a two-direction surveillance point. Built for professional indoor and outdoor surveillance, this SureVision camera supports dependable monitoring across business, government and residential properties.
Supported line-crossing and intrusion tools use human and vehicle classification to help focus attention on relevant activity. Configure the detection zones for the property and use the supported SureVision recorder functions.

Where this camera works best
Choose this model when one mounting point needs to watch two different directions.
- Business: Watch two warehouse aisles, a lobby and corridor, or a loading point and adjacent storage area with separate lenses.
- Government and public facilities: Watch intersecting corridors or two approaches to a public-building entrance with separate views over one Ethernet connection.
- Home: Aim one view toward a front entrance and the other toward a driveway or side approach from a suitable shared mounting point.
Easy installation with one PoE cable
