Extra Info
AI Detection with Perimeter Intelligence
This camera leverages advanced deep-learning algorithms to accurately distinguish between humans, vehicles, and irrelevant motion. By filtering out environmental noise such as swaying trees, shadows, or small animals, the AI significantly enhances the reliability of tripwire and intrusion detection rules. This ensures more accurate, real-world perimeter protection with fewer false triggers — ideal for securing fences, restricted zones, and facility entrances.
SMD Plus Filtering – Smart Motion Detection Plus
SMD Plus technology improves traditional motion detection by analyzing shape and movement patterns to recognize only people and vehicles. It filters out up to 90% of nuisance alarms caused by weather, animals, or background motion like falling leaves. This dramatically reduces unnecessary alerts and makes security responses more efficient and focused.
Starlight for Low-Light Clarity
Dahua’s Starlight technology excels in environments with minimal lighting. It captures clearer, more detailed images in near-total darkness — often producing usable color video even before infrared (IR) illumination is activated. This makes it ideal for surveillance in parking lots, alleyways, and other low-light areas where visibility is crucial during off-peak hours.
Smart Codec Technology – H.265+ / H.264+
The camera supports Dahua’s Smart H.265+ and H.264+ compression formats, which intelligently adapt to motion levels and scene complexity. By dynamically adjusting the bitrate, the camera conserves bandwidth and storage space without sacrificing image quality. This makes it cost-effective and scalable, especially in systems with multiple high-resolution cameras or limited network capacity.
Rugged and Ready – Outdoor-Grade Protection
Encased in a tough metal body with IP67 weatherproof protection, the camera withstands heavy rain, dust, and varying outdoor temperatures. Its rugged design ensures consistent performance in exposed and demanding environments — from construction sites to remote perimeter locations — without the need for additional housing.
Flexible Integration – Broad Compatibility
Designed with system flexibility in mind, this camera supports a wide range of communication protocols including ONVIF, RTSP, FTP, and HTTPS. It integrates seamlessly with most third-party NVRs, cloud platforms, and video management systems (VMS), making it a versatile choice for both new installations and upgrades of existing infrastructure.
AcuPick Compatibility – Smart Search When Paired with AI NVR
While the DH-IPC-HFW3541T-ZAS does not have onboard AcuPick functionality, it supports AI metadata generation such as human/vehicle detection via SMD Plus. When connected to a compatible Dahua AI NVR, this metadata can be used for AcuPick searches—allowing you to quickly find specific human or vehicle-related events without watching hours of footage.
AcuPick Benefits (with AI NVR):
- Filter by person or vehicle presence in recorded video
- Search using visual traits (e.g. clothing color or vehicle type)
- Instantly jump to relevant footage
- Save time on video reviews
- Reduce false alarm clutter from irrelevant motion
Q&A
Q: Can this camera record in color at night?
A: Yes, thanks to Starlight technology, it can retain color in very low light, switching to IR only when needed.
Q: Can I adjust the zoom remotely?
A: Yes, it features a motorized vari-focal lens that can be controlled via the web interface or NVR.
Q: How far does the night vision reach?
A: Up to 60 meters (197 feet) using its built-in IR LEDs.
Q: Does this camera support two-way audio?
A: It has audio input/output ports, but you'll need external microphones/speakers for full two-way communication.
Q: Can I use this without an NVR?
A: Yes, it supports standalone recording to a microSD card (up to 256GB) and cloud/FTP uploads.
Q: What is the benefit of SMD Plus?
A: It greatly reduces false alerts by only notifying you about human or vehicle movement.
Q: Is this camera waterproof?
A: Yes, it's rated IP67 and can operate in harsh rain, dust, or outdoor environments.
Q: Does it work with non-Dahua NVRs?
A: Yes, it supports ONVIF for cross-brand compatibility.
