Wiring: 2-Wire IP / Ethernet PoE
Choose a compatible Dahua digital two-wire IP installation or an RJ45 Ethernet installation with supported PoE. Two-wire operation requires the specified Dahua two-wire IP switch; it is not the two-wire hybrid platform. The 12 V auxiliary output is not a 12 V power input. Use the manufacturer’s power and lock-output limits.
Existing cable can be reused only after checking conductor size, cable condition, distance, polarity where applicable and the manufacturer’s wiring diagram. Matching the wire count alone does not establish compatibility. Locks, gate controls and their power requirements must be checked separately.
2-Wire or Ethernet
Connect via Dahua's 2-wire system or a standard RJ45 network port — whichever suits your cabling. This flexibility makes retrofits and new installs equally straightforward.
Wide Fisheye Coverage
The 2MP low-illumination colour fisheye lens delivers roughly a 168° horizontal field of view, so callers and the area around the door are captured in a single frame.
Clear in Tricky Light
120 dB WDR, 3D noise reduction and auto IR keep video clear against backlight and after dark, while efficient H.265 compression saves storage and bandwidth.
Dual-Lock & PoE
Control an electric lock with exit button and door-status detection, and power everything over standard PoE or a Dahua 2-wire switch for a clean install.
Which wiring system does this product use?Choose a compatible Dahua digital two-wire IP installation or an RJ45 Ethernet installation with supported PoE. Two-wire operation requires the specified Dahua two-wire IP switch; it is not the two-wire hybrid platform. The 12 V auxiliary output is not a 12 V power input.

Can I reuse my existing intercom cable?Existing cable can be reused only after checking conductor size, cable condition, distance, polarity where applicable and the manufacturer’s wiring diagram. Matching the wire count alone does not establish compatibility. Locks, gate controls and their power requirements must be checked separately.
Can it use a normal network cable?Yes. The VTO2202F-P-S3 supports both Dahua 2-wire and a standard RJ45 Ethernet connection, so you can wire it whichever way suits your install.
How wide is the camera view?It uses a 2MP fisheye lens with roughly a 168° horizontal field of view, capturing callers and the surrounding area in one frame.
How is it powered?Via a Dahua 2-wire switch, DC 48V, or standard PoE. Power consumption is around 12W.
Which indoor monitor does it pair with?It pairs with Dahua indoor monitors (VTH series). Contact our team for a matching monitor to complete your intercom.
