Perfect For:
- Residential gates and driveways
- Small business storefronts
- Office building entrances
- Warehouse perimeters
- School or campus walkways
- Indoor hallways or corridors with variable light
Install Tips
- Use the 2.8mm lens for wider areas like driveways or lobbies; choose 4.0mm for tighter spaces or hallways.
- Install between 2.5m–3.5m height for optimal face detection and scene coverage.
- Take advantage of ePoE to simplify wiring on longer runs — up to 800m with Cat 5e.
- Pair with a Dahua NVR or ONVIF-compliant recorder for best compatibility.
- Enable WDR for areas with glass doors or windows facing sunlight.
- Mount with accessories like the PFB204W wall mount or PFA130-E junction box for secure installs.

Extra Info
ePoE Technology – Long-Distance Power and Data Over One Cable
Dahua’s enhanced Power over Ethernet (ePoE) allows for power and data transmission over significantly extended distances—up to 800 meters with Cat 5 Ethernet cable or 300 meters over coaxial cable. This eliminates the need for repeaters, extra switches, or separate power sources, making it a cost-effective solution for sprawling installations such as parking lots, perimeter fences, warehouses, or multi-building campuses.
IVS and Face Detection – Smarter Alerts with AI Precision
The camera is equipped with Intelligent Video System (IVS) functions including tripwire detection, intrusion alerts, and object disappearance monitoring. It also supports AI-based face detection, automatically capturing and uploading snapshots of faces when individuals enter key areas. These features enhance security in entryways, checkpoints, access-controlled zones, and high-traffic entrances.
Smart H.265+ Compression – Efficient Storage with Intelligent Encoding
Using scene-adaptive encoding, Smart H.265+ dynamically adjusts bitrate based on motion and visual complexity. This reduces storage and bandwidth requirements by up to 70% compared to standard H.265, all while preserving image quality. It’s ideal for systems that require continuous 24/7 recording, remote streaming, or operate on limited data plans or storage space.
Rugged Environmental Protection – Built to Withstand the Elements
Engineered for demanding conditions, the camera is IP67-rated for complete protection against dust, rain, and water jets. It operates reliably in extreme temperatures from -30°C to +60°C, making it ideal for year-round outdoor deployment in regions with harsh winters, hot summers, or coastal humidity.
WDR (120dB) for Balanced Exposure – Clarity in Mixed Lighting
With 120dB Wide Dynamic Range (WDR), the camera delivers balanced images in scenes with harsh lighting contrasts—such as sunlight streaming through windows or people entering from a bright exterior into a dim hallway. WDR ensures both bright and shadowed areas are clearly visible, reducing blind spots in lobbies, glass-walled storefronts, and entry vestibules.
Q&A
Q: Can this camera record in colour at night?
A: No, it uses IR night vision. Colour is available only during daytime or in well-lit scenes.
Q: Does this support audio?
A: Yes, it has a built-in microphone that records ambient audio.
Q: How far can the camera see at night?
A: Up to 50 meters (164 ft) using Smart IR.
Q: Is it compatible with other brand NVRs?
A: Yes, it supports ONVIF and works with most major third-party NVRs.
Q: Can I use this camera for face recognition?
A: No, it only supports face detection — it captures and sends snapshots but doesn't identify individuals.
Q: Can I run both data and power over one cable?
A: Yes, using ePoE, it can transmit both over Cat5/Coax up to 800m.
Q: How much video can a 128GB microSD card hold?
A: With Smart H.265+ compression, roughly 2–4 weeks of footage depending on scene activity and recording settings.
Q: Is this camera vandal-resistant?
A: While it's IP67 weather-rated and made of metal, it does not carry an IK10 vandal rating.
