Product Description
The Dahua IPC-HFW3541E-AS-S2 is a 5MP outdoor bullet camera that spots people and vehicles rather than just "something moved". That's what WizSense AI does: it uses intrusion and tripwire detection with human/vehicle classification, so you get fewer false alerts from cats, leaves or headlight glare than a basic motion-detection camera.
What it actually gives you
- Resolution: up to 5MP (2960 × 1668) at 20fps, or 4MP at up to 30fps for smoother footage
- Night vision: built-in IR LEDs reaching 50 metres, for genuine 24/7 coverage
- Sensor: 1/2.7" CMOS, chosen for low-light detail rather than daytime sharpness alone
- Compression: H.265, which keeps recordings smaller so a given hard drive lasts longer
- Storage: microSD slot up to 256GB, useful as local backup alongside an NVR
- Power: runs on PoE (power and data over one network cable) or 12V DC — check your switch or NVR supports PoE before assuming one cable is all you need
- Housing: IP67-rated, built for wall or eave mounting outdoors
- Extras: built-in microphone, audio and alarm input/output, privacy masking, and system alerts for things like a disconnected network or SD card fault
Before you buy
Confirm your recorder or NVR is Dahua-compatible (or supports standard ONVIF) and that your switch has a free PoE port if you're not running a separate power supply.

Frequently Asked Questions
Does this camera need a separate power supply?
No — it supports PoE (power and data over one cable) as well as 12V DC, so a PoE switch or NVR removes the need for a separate power lead.
How far does the night vision reach?
The built-in IR LEDs give a range of up to 50 metres, which is enough for most garden, driveway or car park coverage.
Will it tell the difference between a person and a passing car?
Yes — WizSense AI includes intrusion and tripwire detection with classification of humans and vehicles, cutting down false alarms from other movement.
Can it record without an NVR?
It has a microSD slot supporting cards up to 256GB, so it can store footage locally as well as feeding an NVR.
