What the DH-SD49425GB-HNR features actually look like
Representative illustrations of how each key feature performs in a real scene.
4MP Ultra HD
4MP captures roughly twice the detail of standard 1080p.
Human/Vehicle Detection
Smart detection focuses on people and vehicles and can ignore things like swaying branches, rain or small animals — helping cut down false alerts and making the right moments easier to find.

§ 07Questions
Frequently asked about the DH-SD49425GB-HNR
Q.01
How does this compare to the Hikvision DS-2DE4A425IWG-E?
Very similar spec: both 4 MP, 25× zoom. The Dahua has SMD 4.0 (newer AI), Quick Pick search, and face detection. The Hikvision has DarkFighter and auto-tracking. Both need PoE+.
Q.02
Does it have active deterrence (siren/strobe)?
No. This is an IR-only PTZ with no strobe or speaker. For TiOC deterrence in a Dahua PTZ, look at the SD3E405DB or SD6C3425 models.
Q.03
What is Quick Pick?
Dahua's fast target search feature. It indexes people and vehicle targets in recorded footage for rapid retrieval.
Q.04
Does it support auto-tracking?
Basic auto-tracking is available. For advanced tracking, the WizMind series offers more sophisticated algorithms.
Q.05
What SD card does it support?
Up to 256 GB microSD.
