Dahua DH-IPC-HFW3541TP-ZAS-27135-S2 — 5MP Bullet IP Camera
The Dahua DH-IPC-HFW3541TP-ZAS-27135-S2 is a 5MP WizSense bullet IP camera fitted with a 2.7-13.5mm motorised varifocal lens, giving installers on-site control over field of view without needing to swap lenses. The WizSense engine adds deep-learning human and vehicle classification, helping to cut down on false alerts from pets, weather and other non-target movement.
Who is it for?
IP cameras carry video and PoE power over one Cat5e/Cat6 cable to a PoE NVR — ideal when cabling from scratch or wanting resolutions/analytics beyond coax. At 5MP with adjustable 2.7-13.5mm optics, this camera suits mid-range coverage such as car parks, warehouse yards, retail frontages and building perimeters where the installer needs to fine-tune the angle of view on site. The built-in human/vehicle classification and triple-stream output make it a practical choice for sites that want smarter alerts without stepping up to a full AI-analytics camera.

What you will need
- A PoE NVR with a spare channel that supports 5MP recording
- Cat5e or Cat6 cable run from the camera to the NVR (or switch) — one cable carries both video and power
- For long runs or where you need to branch out to several cameras, add a PoE switch between the camera and NVR
- If recording people, check local signage/GDPR requirements for the site
Frequently asked questions
Will this camera work with a non-Dahua NVR?
Yes — it supports ONVIF, so it will connect to most third-party NVRs, though some Dahua-specific features may only be available with a Dahua recorder.
Does it need a separate power supply?
No, provided it is connected to a PoE NVR or PoE switch, power is delivered over the same network cable as the video feed.
How much storage will I need?
Storage depends on resolution, frame rate, number of cameras and how long you need to retain footage — as a rough guide, higher resolution and longer retention both increase storage requirements, so check with us before committing to a specific NVR/HDD size.
Can I adjust the field of view after installation?
Yes — the 2.7-13.5mm motorised varifocal lens can be adjusted remotely from the NVR or VMS, without needing to physically refocus the camera.
