Extra Info
Starlight Technology for Unrivaled Night Vision
The DH-PTZ19245U-IRB-N integrates Dahua’s Starlight Ultra-low Light Technology, which allows the camera to capture vivid color details even in near-dark conditions, down to 0.005 lux. This is achieved through a combination of a large aperture lens, a high-performance sensor, and advanced image processing. For users, this means that critical details, such as clothing colors or vehicle descriptions, remain visible long after traditional cameras switch to black and white, significantly improving evidence quality for security incidents occurring at night. When combined with its powerful IR illumination, which extends up to 350 meters, the camera provides a complete 24/7 surveillance solution, ensuring no blind spots even in total darkness.
Intelligent Video System (IVS) and Advanced Analytics
Beyond basic motion detection, this camera features Intelligent Video System (IVS) analytics, including Tripwire and Intrusion detection. Tripwire allows you to define a virtual line, triggering an alarm when an object crosses it in a specified direction. Intrusion detection sets up a virtual perimeter, alerting you when an object enters or exits the defined area. These features are crucial for automated security monitoring in sensitive zones, significantly reducing false alarms by focusing on relevant events. Furthermore, the camera supports advanced intelligent functions like Face Detection, which can be invaluable for identifying individuals in monitored areas, and Heat Map, which can provide insights into traffic flow and popular areas within the surveillance scene.
Seamless Integration and Remote Management
The DH-PTZ19245U-IRB-N is designed for broad compatibility, conforming to ONVIF Profile S&G specifications. This ensures it can integrate smoothly with a wide range of network video products from various manufacturers, offering flexibility in building or expanding existing surveillance systems. For local and remote management, users can access the camera through popular web browsers (IE, Chrome, Firefox, Safari) or dedicated management software like Smart PSS, DSS, and DMSS. Mobile apps for iOS and Android devices provide convenient access to live views, playback, and configuration on the go, ensuring you're always connected to your security.
Optimized Compression with Smart H.265+
The implementation of Smart H.265+ video compression is a significant advantage for long-term surveillance operations. This advanced encoding strategy dynamically adjusts bit rates based on scene complexity, movement, and regions of interest, while also incorporating intelligent noise reduction. The result is high-quality video that consumes significantly less bandwidth and storage space—up to 70% less compared to standard H.265. For businesses and large-scale deployments, this translates to substantial savings on storage infrastructure costs and more efficient use of network resources, allowing for longer recording durations or higher quality streams without upgrading existing hardware.
Reliable Operation in Harsh Environments
This camera is built to withstand extreme outdoor conditions, offering robust environmental protection. It boasts an IP68 ingress protection rating, meaning it is fully protected against dust and can withstand continuous immersion in water up to a certain depth. It also meets NEMA 4X standards, indicating superior protection against dust, dirt, hose-directed water, and corrosion. Its ability to operate in temperatures ranging from -50°C to +70°C, combined with a ±25% input voltage tolerance and 8KV lightning rating, ensures uninterrupted performance even in the most unstable power conditions or severe weather events, providing true all-environment reliability.
Cybersecurity Protections
Dahua builds in strong cybersecurity protections including encrypted video streams, secure firmware updates, and access controls. This guards against data breaches or unauthorized remote access — a key consideration for business and home networks alike.

Q&A
Q: Can this camera record in color at night?
A: Yes, thanks to Starlight Technology, this camera can capture detailed color images in very low-light conditions (down to 0.005 Lux). In complete darkness, its IR illuminators will provide clear black and white footage up to 350 meters.
Q: Does this camera have two-way audio?
A: This camera has an audio input and output (1 in / 1 out), allowing for one-way audio transmission (listening in or broadcasting messages via a connected speaker, depending on your setup). It does not have a built-in speaker and microphone for immediate two-way communication without external equipment.
Q: How does the auto-tracking feature work?
A: The auto-tracking feature automatically adjusts the camera's pan, tilt, and zoom to follow a detected moving object and keep it within the scene. This can be triggered manually or automatically by predefined rules like tripwire or intrusion detection.
Q: Can this camera be used with an NVR from a different brand?
A: Yes, the camera conforms to ONVIF Profile S&G specifications, which ensures interoperability with many third-party NVRs and network video products, regardless of the manufacturer.
Q: How long can the camera record on a 256GB microSD card?
A: The recording duration on a 256GB microSD card will depend heavily on the resolution, frame rate, and the amount of motion in the scene. However, with Smart H.265+ compression, it can record significantly longer than cameras using standard H.264, potentially offering several days to weeks of continuous recording in typical scenarios.
Q: What is the main difference between the models with and without "-B" in the part number?
A: The "-B" in the model number, such as DH-PTZ19245U-IRB-N-B, indicates that the camera has "Bottom outlets," referring to the location of the cable connections. Models without the "-B" typically have "Side outlets." This primarily affects installation and cable management.
Q: Can the smart wiper be turned off?
A: The Smart Wiper feature automatically starts and stops based on the built-in rain sensor. While the document doesn't explicitly state a manual override, most advanced cameras offer configuration options through the web interface or management software to disable or adjust automated features if desired.
