Dahua HAC-T1A21P 2MP Bullet Camera Performance Breakdown

The Dahua HAC-T1A21P 2MP is a budget-friendly bullet camera geared towards basic security needs in well-lit or controlled lighting environments. Here’s a breakdown of its performance in key areas:

Image Quality:

• Resolution: With a 2MP (1080p) sensor, the camera delivers good image quality during daytime and well-lit conditions. You can expect clear visuals for identifying people and objects within its field of view.
• Low-Light Performance: Here’s where limitations arise. The camera lacks traditional IR illuminators. While it boasts Starlight Technology for enhanced low-light sensitivity, it might not be sufficient for capturing details in complete darkness.

Night Vision:

• Effective Range: Starlight Technology claims night vision up to 30 meters. However, image quality at this distance might be grainy and lack clarity, especially for identifying facial features or small objects.

Video Compression:

• H.265+ and other codecs: The camera supports various video compression formats like H.265+ and H.264. These codecs help reduce file size without sacrificing significant image quality, saving storage space and bandwidth.

Other Performance Considerations:

• Field of View: The 3.6mm fixed lens offers a moderate field of view, suitable for capturing activity in smaller areas. Wider fields of view require different lens options (sometimes sold separately).
• Weatherproofing: The IP67 rating ensures the camera is dustproof and water-resistant, making it reliable for outdoor use.

Overall Performance:

The Dahua HAC-T1A21P 2MP camera is a decent performer for basic security needs in controlled lighting environments. However, users seeking exceptional low-light performance or high-resolution detail might need to consider cameras with stronger night vision capabilities or higher megapixel sensors.

Here are some additional points to consider:

• Frame Rate: Information on the camera’s frame rate is unavailable readily. A higher frame rate (e.g., 60fps) captures smoother motion compared to a lower frame rate (e.g., 30fps).
• Advanced Features: This camera might lack advanced features like motion detection or tamper alerts, which are common in higher-end models.

Overall, the Dahua HAC-T1A21P 2MP camera is a good option for those looking for a reliable and affordable HD security camera for outdoor use.
