Extra Info
Starlight Technology for Superior Low-Light Performance
Dahua's Starlight technology is a game-changer for surveillance in challenging low-light conditions. Unlike traditional cameras that might switch to black and white or produce grainy images, Starlight cameras can capture clear color details even when light levels drop as low as 0.005 lux. This is achieved through a combination of large aperture lenses, high-performance sensors, and advanced image processing. For users, this means that even at dawn, dusk, or in dimly lit areas, you still get crucial color information, such as the color of a car or clothing, which is vital for identification and evidence gathering. This capability extends your active surveillance period significantly, ensuring comprehensive coverage around the clock.
Intelligent Video System (IVS) for Proactive Security
The Intelligent Video System (IVS) built into this camera goes beyond basic motion detection, offering more sophisticated analysis of the scene. Features like Tripwire allow you to set a virtual line, and the camera will trigger an alert if an object crosses it in a specified direction. Intrusion detection enables you to define a virtual area, and an alarm is triggered if an object enters or loiters within it. These advanced analytical capabilities provide a more proactive security approach. Instead of simply recording everything, the camera can intelligently identify potentially suspicious activities, reducing false alarms and ensuring that you are only alerted to events that truly matter. This leads to more efficient monitoring and quicker response times.
Efficient Video Compression with H.265
The inclusion of H.265 (High Efficiency Video Coding) is a significant benefit for both storage and bandwidth management. Compared to older compression standards like H.264, H.265 can effectively double the data compression ratio at the same level of video quality. This means you can store twice as much video footage on your Micro SD card or NVR hard drive, or stream high-quality video using half the bandwidth. For users, this translates to longer recording archives without needing larger storage devices and smoother remote viewing, especially over slower internet connections. It's a crucial technology for optimizing your surveillance system's performance and cost-effectiveness.
Robust Environmental Protection (IP66 & IK10)
The IP66 and IK10 ratings of this camera signify its readiness for deployment in harsh outdoor environments. IP66 certifies the camera as "dust tight" and protected against powerful jets of water, meaning it can withstand heavy rain, sprinklers, and dust storms without compromising its internal components. The IK10 rating is a measure of its resistance to mechanical impact, indicating that the camera can withstand significant force (equivalent to a 5 kg object dropped from 40 cm), protecting it from vandalism or accidental damage. These ratings provide peace of mind, ensuring the camera remains operational and reliable even when exposed to challenging weather conditions and potential tampering.
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.

Summary Recommendation
- Choose the Newer Model (DH-SD22204UE-GN) if:
- You require significantly improved low-light performance, as indicated by the lower minimum illumination values (0.005 Lux color, 0.0005 Lux B/W).
- You need the more efficient H.265 video compression for reduced bandwidth and storage requirements.
- The inclusion of Face Detection as an advanced intelligent function is critical for your surveillance needs.
- Slightly improved DORI distances are beneficial for detection and recognition at longer ranges.
- The Older Model (DH-SD22202UE-GN) might still be suitable if:
- Budget is a primary concern, and the enhanced low-light performance or H.265 compression of the newer model is not strictly necessary for your application.
- Your existing infrastructure primarily uses H.264+/H.264, and the transition to H.265 is not a priority.
- Basic IVS features (Tripwire, Intrusion, Abandoned/Missing) are sufficient, and advanced features like Face Detection are not required.
