Video and Imaging

NE503 video capabilities are configured across two pages: Media handles "encode and stream the picture out," while Image handles "get the picture right and overlay content." This chapter follows the operational order.

Media (Live View and Streams)

Go to the Media page: the main area shows the live feed, the toolbar sits above it, and the right-side Configuration panel configures streams and RTSP.

Toolbar

Button	Action
Volume	Adjust monitoring volume
Talk	Press and hold to talk (requires a speaker on the device)
Stream Info	Show the current stream's codec / resolution / frame rate / bitrate
Snapshot	Capture the current frame as an image
Fullscreen	Full-screen view

Stream Settings

The device provides Main / Sub / Third streams, each independently configurable. Switch between them at the top of the right panel:

Parameter	Description	Selection guidance
Enable Stream	Whether this stream is active	Disable unused streams to save resources
Codec	Encoding format (H.264 / H.265)	H.265 gives lower bitrate at equal quality; confirm the receiver supports it
Resolution	Resolution	1920×1080 recommended for the main stream; 4K for high-detail scenes
Frame Rate	Frames per second	Typically 25/30; raise for fast-motion scenes
Bitrate	Bitrate (Kbps)	Higher is clearer but uses more bandwidth
I-Frame Interval (GOP)	I-frame interval	Larger compresses better but increases seek latency

Typical division of labor: main stream for recording, sub stream for live preview, third stream for AI analysis or mobile.

RTSP Streaming

Enable Enable RTSP Stream to expose the selected stream as a standard RTSP address. The URL appears in the input box with one-click copy:

Stream	URL
Main	rtsp://<device-ip>:8554/main
Sub	rtsp://<device-ip>:8554/sub
Third	rtsp://<device-ip>:8554/third

Default port: 8554.

Verify RTSP with VLC

RTSP is the primary protocol for integrating NE503 with NVR / VMS platforms. Verify the stream quickly with VLC:

1. Open VLC → Media → Open Network Stream, and enter the RTSP URL from the table above:

2. Click Play and confirm smooth playback without artifacts:

If the stream won't pull, check stream status with aipc-cli stream list.

Image (Picture, Overlays, and Lens)

The Image page has three sub-tabs: Image / Overlay / Control — Image adjusts quality and transforms, Overlay adds overlays and privacy masks, Control drives the lens and IR.

Quality and Transform (Image Tab)

AI ISP — Enable Enable AI ISP to enhance image quality with AI (low-light brightening, denoising, wide dynamic range, etc.); disable to use the traditional ISP. Recommended for low-light or high-dynamic-range scenes.

ISP Settings

Option	Description	When to use
Manual Mode	When enabled, manually adjust exposure, gain, and white balance; when disabled, all three are automatic	Leave off for general use; enable when you need fixed exposure (e.g., license-plate recognition)
Powerline Frequency	50Hz / 60Hz — must match the local lighting	Choose 50Hz for 220V regions (China, Europe); a mismatch causes flicker bands
White Balance	White balance mode (Auto / preset / manual color temperature)	Auto for most scenes; switch to manual when colors look off

Transform

Option	Effect	When to use
Rotation	Rotate the frame (0° / 90° / 180° / 270°)	Select the matching angle when mounted upside down or sideways
Flip	Horizontal / vertical flip	Special mirrored-mount scenarios
Distortion	Lens distortion correction toggle	Enable when wide-angle edge distortion is visible
Grayscale	Grayscale mode	Nighttime IR scenes — reduces false colors
Digital Stabilization (DIS)	Software stabilization, no gyroscope required, crops the frame edges to compensate for shake	Use when there is no IMU
Electronic Stabilization (EIS)	Gyro-based stabilization (requires IMU); outperforms DIS	Prefer when an IMU is present; an abnormal attitude degrades the effect (relies on Dashboard gyro data)

Overlays and Privacy Masking (Overlay Tab)

Overlays add information to the frame (text, time, images) or mask sensitive areas. Select the target Stream at the top — each stream is configured independently. All overlays can be dragged directly on the live feed: double-click text to edit, drag the corner handle to resize.

Information Overlays

Type	Description	Notes
Text Overlay	Custom text (e.g., a location name "Front-Door-01")	Configurable font size, show/hide, multiple entries
DateTime Overlay	Date-time stamp	Configurable font size and corner position (Top-Left / Top-Right / Bottom-Left / Bottom-Right)
Image Overlay	Upload a custom image (e.g., a logo) onto the frame	Up to 3 per stream

Privacy Masking

Type	How it masks	Suited for
Privacy Mask	Draw polygons over fixed areas to be permanently blocked from the frame	Fixed regions you never want captured (a neighbor's window, an operator console)
AI Auto Mask	AI detects specific targets (faces, license plates) and masks them in real time, following them as they move	GDPR and similar privacy-compliance scenarios

The two are independent: Privacy Mask blocks a fixed position, regardless of what enters it; AI Auto Mask blocks specific targets, following them as they move. AI Auto Mask depends on AI inference.

Lens and IR (Control Tab)

Lens Control

Item	Effect
Zoom	Zoom slider (shows the multiplier, e.g., 1.0x)
Focus	Focus slider (shows the position percentage and zone, e.g., MID)
One-shot AF	Click once to trigger a single autofocus at the current zoom
Reset to 1.0x	Return to the minimum zoom
IR-Cut Filter	Infrared cut filter toggle — on during the day for accurate color, off at night to let in infrared light (the status text indicates the current mode)

IR Light Control

Item	Effect
Near IR	Short-range IR fill light toggle + brightness slider
Far IR	Long-range IR fill light toggle + brightness slider

Enable as needed for night or low-light scenes; adjust brightness based on distance and scene. Note that fill lights add to power draw and heat.

To control the lens or IR remotely from an app (e.g., programmatic zoom), the app must be installed with the Device Control permission.
