Extra Info

SMD Plus

This camera uses Dahua’s Smart Motion Detection (SMD Plus) to analyze movement and ignore non-threats like pets, rain, or shadows. It focuses only on humans or vehicles, so you don’t get bombarded with false alerts.

Perimeter Protection

Using advanced deep learning, it can detect if someone crosses a virtual line (tripwire) or enters a zone (intrusion). It works especially well for fenced-off areas, yards, or driveways.

Starlight Technology

Even when there’s barely any light, this camera can capture clear and color-rich video using its starlight-enhanced sensor. No need for external lighting.

Smart Codec (H.265+)

This advanced compression keeps videos looking sharp while reducing the space needed to store them. That means more days of footage saved to your SD card or NVR.

Built-in Audio

The internal microphone records background sounds, which can help clarify what’s happening in footage.

Cyber Security Features

Includes video encryption, secure access, and support for trusted firmware upgrades to protect from hacks.

Q&A

Q: Does this camera record color at night?
A: It uses IR at night, but thanks to starlight tech, the image is brighter and clearer than standard IR.

Q: Can I use it without an NVR?
A: Yes, it supports up to 256GB MicroSD for local recording.

Q: Is it compatible with third-party NVRs?
