Installer Tips
-
Optimal Mounting: For effective PTZ and AI functionality, install the camera at a height that provides a clear, unobstructed view of the area of interest, typically between 2.5 to 4 meters (8 to 13 feet) to maximize the DORI distances.
-
PoE for Simplicity: Utilize Power over Ethernet (PoE) for installation to simplify wiring, as it delivers both power and data through a single Ethernet cable, reducing clutter and installation time.
-
Lens for Coverage: The 2.8mm-12mm varifocal lens is versatile; use the wider 2.8mm end for broad overview of an area and zoom in to 12mm for detailed surveillance of specific points.
-
Pairing with NVRs: For optimal performance and storage management, pair this camera with a Dahua NVR, especially those with AI capabilities, to leverage features like advanced search and event recording.
-
Testing AI Zones: After installation, meticulously test and fine-tune your Perimeter Protection and People Counting zones to ensure accurate detection and minimize false alarms.
-
Environment Considerations: While IP66 and IK08 rated, consider additional protection like an overhang or recessed mounting in areas prone to extreme weather or direct impact for extended durability.

Extra Info
WizSense AI for Smarter Monitoring
The SD1A404XB-GNR is part of Dahua's WizSense series, which means it incorporates an independent AI chip and deep learning algorithms. This isn't just about motion detection; it's about intelligent analysis. The camera can accurately differentiate between humans and vehicles versus other moving objects like animals or rustling leaves. This significantly reduces the nuisance of false alarms, allowing you to focus on genuine threats and critical events. For example, in a retail environment, it can trigger an alarm only when a person enters a restricted area after hours, ignoring a cat passing by.
Starlight Technology for Vivid Night Vision
Traditional cameras often struggle in low-light conditions, producing grainy or entirely black and white images. This camera's Starlight Technology is a game-changer. It leverages a large sensor and advanced image processing to capture remarkably clear color video even when ambient light levels drop as low as 0.005 Lux. This means you can distinguish colors of clothing, vehicles, or other details in dimly lit environments where standard cameras would only show a monochrome outline, providing richer evidence for investigations.
DORI Distance Explained for Practical Use
The DORI Distance (Detect, Observe, Recognize, Identify) provides a practical guide for how far away you can expect to perform specific surveillance tasks. For this camera, you can detect a person up to 240 meters away (meaning you can tell something is there), observe them up to 95 meters (you can get general details), recognize them up to 48 meters (you might know someone familiar), and identify them up to 24 meters (sufficient detail to confirm identity). This helps in planning camera placement to ensure it meets your specific surveillance needs.
Robust Protection for Outdoor Durability
This camera is built to withstand challenging outdoor environments. Its IP66 rating means it's completely protected against dust ingress and powerful water jets, making it suitable for exposed outdoor installations. The IK08 vandal-resistant rating indicates it can withstand significant impacts, providing peace of mind against deliberate attempts to damage the camera. Coupled with a wide operating temperature range from -30°C to +60°C, this camera offers reliable performance in diverse climates
Q&A
Q1: Can this camera record in color at night?
A1: Yes, thanks to its Starlight technology, the camera can capture clear color images in extremely low-light conditions, down to 0.005 Lux. In complete darkness, its IR illuminators will activate, providing sharp black and white video up to 15 meters.
Q2: How loud is the speaker on this camera?
A2: This camera supports audio input and output, but it doesn't have a built-in speaker. You would need to connect an external speaker to the audio output port to enable two-way audio communication.
Q3: Can the infrared (IR) lights be disabled?
A3: Yes, the IR illuminators have control options including Zoom Prio, Manual, and SmartIR, allowing you to manage when they are active. You can set them to turn off if external lighting is sufficient.
Q4: Does this camera work with Network Video Recorders (NVRs) from other brands?
A4: This camera supports ONVIF Profile S&G&T, which means it's designed to be interoperable with NVRs and other IP-based security products from various manufacturers that also adhere to the ONVIF standard. However, some advanced AI features might be best utilized with a compatible Dahua NVR.
Q5: How long can the 256GB Micro SD card record footage?
A5: The recording duration on a 256GB Micro SD card will vary significantly based on factors like resolution, frame rate, compression (H.265+ will extend it significantly), motion activity, and whether continuous or event-based recording is used. With efficient H.265+ compression and motion-only recording, it could potentially store weeks of footage, but continuous recording at 4MP 30fps would fill up much faster.
Q6: What makes this WizSense model different from a "Pro" version of a PTZ camera?
A6: WizSense models, like this one, offer intelligent AI features focused on human and vehicle detection, providing practical benefits for everyday surveillance. "Pro" versions often include more advanced optical capabilities (e.g., higher optical zoom, larger sensors), more robust build materials, and potentially more specialized or higher-end AI analytics for complex, large-scale projects. This WizSense camera balances advanced features with cost-effectiveness and a compact design.
Q7: Will the Perimeter Protection siren activate automatically?
A7: This camera supports Perimeter Protection for alarm triggering, but it does not have a built-in siren or active deterrence features like red/blue lights or a siren. When a tripwire or intrusion is detected, it can trigger events like sending notifications, recording to storage, or uploading images to FTP. You would need an external alarm system integrated with the camera for audible alerts.

Summary Recommendation
-
Choose the SD1A404XB-GNR (Newer Model) if:
- You require higher resolution (4MP) for more detailed surveillance.
- Advanced AI features like Face Detection, People Counting, and improved Perimeter Protection with target classification (human/vehicle) are critical for your application.
- You need a 4x optical zoom for flexible field-of-view adjustments without digital degradation.
- The enhanced DORI distances (e.g., Detect up to 240m) are important for covering larger areas effectively.
-
The DH-SD1A200T-GN (Older Model) might still be suitable if:
- A 2MP resolution is sufficient for your monitoring needs.
- Your budget is a primary concern, as older models are typically more cost-effective.
- Basic IVS features (Tripwire, Intrusion, Object Abandoned/Missing) are enough, and advanced AI analytics like Face Detection or People Counting are not required.
- You don't need optical zoom, as this model comes with a fixed lens.
