TiOC DUO · 180° PANORAMIC · 8MPDahua DH-IPC-PFW3859S-A180-AS-PV-ANZ-S2 8MP TiOC Duo 180° Panoramic Camera
See a wide driveway, frontage or car park in one panoramic image. The DH-IPC-PFW3859S-A180-AS-PV-ANZ-S2 combines two 4MP imaging channels into a 4320 × 1944 view, with Smart Dual Light, two-way audio and audible/visual warnings. It is a fixed panoramic camera, not a mechanically rotating PTZ.
Key Features
One 180° overview
Dual 2.8mm lenses produce a 180° horizontal and 72° vertical view, helping you follow activity across a broad scene.
Smart Dual Light
Up to 30m IR and 30m warm illumination support night monitoring. Colour capture requires available scene light or the camera’s warm illumination.
Active deterrence and talk
Built-in microphones and a speaker support two-way talk and configured audible warnings, alongside visual warning lights.
Smarter event handling
Xinghan Vision, SMD 4.0, perimeter rules and compatible AcuPick search help identify relevant human and vehicle events.

Setup and Compatibility
Use a PoE+ supply and protect all outdoor cable joints from water. Position the camera for a clear, unobstructed panoramic scene and test faces at the distances that matter: a 180° overview is not a promise of identification detail across the entire scene. A compatible NVR must support the camera’s panoramic resolution and the analytics you intend to use. Firmware and configured operating modes affect feature availability.
Choosing Accessories
Use the PFA130-E junction box, PFA157 pole bracket or PFA151 corner bracket as appropriate. Add a surveillance microSD card for local recording and a suitable Cat6 lead.
Compare Dahua Xinghan AI cameras and NVRs to choose a camera for your scene and a recorder with the required channels, storage and search features. Feature names alone do not guarantee end-to-end compatibility.

Frequently Asked Questions
Does the camera physically pan and tilt?
No. Its lenses are fixed. ePTZ crops and enlarges part of the panoramic image electronically.
Can it record without an NVR?
An optional microSD card up to 512GB supports local recording after configuration. A recorder is useful for central storage and compatible search functions.
Does ordinary 802.3af PoE suffice?
The specified network power standard is 802.3at PoE+. Check the switch or NVR port before installation.
