Audio & Video Settings

The Audio/Video section contains all settings related to how the camera outputs, encodes, and streams video and audio. It is organized into three main tabs: AVoIP, Video, and Audio.

caution

Changes to audio/video encoding and streaming settings affect live output immediately or after saving. Modify these settings during scheduled maintenance windows to avoid disrupting active streams.

AVoIP Tab

The AVoIP (Audio/Video over IP) tab contains sub-tabs for each supported streaming protocol. Your camera can simultaneously output video via multiple protocols.

RTMP

Real-Time Messaging Protocol — used for streaming to platforms like YouTube Live, Facebook Live, Vimeo, and custom RTMP ingest endpoints.

Field	Description
Stream 1 URL	Defines the RTMP URL from your streaming platform (e.g., rtmp://a.rtmp.youtube.com/live2)
Stream 1 Key	Defines the stream key provided by your platform
Stream 1 Enable	Toggle to start/stop the Stream 1 RTMP output
Stream 2 URL	Defines the secondary RTMP destination
Stream 2 Key	Defines the stream key for the secondary destination
Stream 2 Enable	Toggle for Stream 2 RTMP output

tip

RTMP supports simultaneous dual-stream destinations, very useful for simulcasting to two platforms at once (e.g., YouTube and a backup server).

SRT

Standing for Secure Reliable Transport, this is a low-latency, firewall-friendly streaming protocol ideal for contribution over the internet or challenging network conditions.

Field	Description
Enable	Toggle to enable/disable SRT output.
Mode	Listener: camera waits for an incoming SRT connection; Caller: camera initiates the SRT connection to a server.
Server	IP address or hostname of the SRT destination (used in Caller mode).
Port	Default: 4578
Encryption	None / AES-128 / AES-192 / AES-256.
Password	Passphrase for encrypted SRT streams.
Bandwidth Overhead	Default: 25% extra bandwidth reserved for packet recovery.
Latency	Default: 500ms buffer depth; higher values increase resilience at the cost of added delay.
Stream ID	Optional identifier string sent with the stream.

note

Listener vs. Caller:

• Use Listener when your decoder/receiver will initiate the connection to the camera
• Use Caller when the camera should push the stream to a receiving server

RTP (Multicast) RTSP (Unicast)

Protocol	Field	Description
RTSP Unicast	Authentication	Enable/disable authentication for RTSP connections.
	Port	Default: 554 (standard RTSP port).
RTP Multicast	Enable	Toggle multicast output on/off.
	IP	Multicast group address (default: 234.1.2.88).
	HD Port	High-definition stream multicast port (default: 6688).
	SD Port	Standard-definition stream multicast port (default: 6690).

tip

RTSP Connection String

To pull the RTSP stream from most media players and systems:

rtsp://[camera-ip]:554/stream1

ONVIF

ONVIF (Open Network Video Interface Forum) provides standardized discovery and control for IP cameras. Compatible with video management systems (VMS), NVRs, and most professional AV/IT infrastructure.

Field	Description
Enable	Toggle ONVIF support on/off (currently On by default).
Authentication	Enable/disable authentication for ONVIF connections.

note

ONVIF must be enabled for the camera to be discoverable by ONVIF-compatible VMS platforms and network video recorders.

NDI®

Network Device Interface (NDI®) by NewTek/Vizrt enables low-latency, high-quality video transport over standard gigabit Ethernet, no additional hardware required.

Field	Description
Local Device Name	The name your camera advertises on the NDI network.
Local Device Channel	Channel number (or name) your camera appears as for other NDI devices.
Receive Group	NDI receive group for filtering discovery.
Discovery Server	Toggle to use an NDI Discovery Server instead of mDNS broadcast.
Discovery Server Address	IP address of your NDI Discovery Server.
Multicast Server	Toggle NDI multicast mode.
Port	NDI port number.
Video Template	Sets the NDI encoding quality/format.

NDI Video Templates

Template	Description
Off	NDI output disabled
Ultra	Highest quality, highest bandwidth
High	High quality
Medium	Balanced quality and bandwidth
Low	Lower bandwidth for constrained networks
NDI|HX3 264P50	H.264 compressed NDI HX3 at 50fps
NDI|HX3 264P60	H.264 compressed NDI HX3 at 60fps
NDI|HX3 265P50	H.265 compressed NDI HX3 at 50fps
NDI|HX3 265P60	H.265 compressed NDI HX3 at 60fps

tip

NDI Full Bandwidth (Ultra/High) requires a dedicated gigabit network segment. NDI HX3 is compressed and works well over standard networks while still maintaining very low latency.

Video Tab

The Video tab controls how the camera encodes and outputs its video signal.

caution

Changes to video encoding and output format settings can affect live output immediately after clicking Apply. Modify these settings during scheduled maintenance windows to avoid disrupting active streams or recordings.

HDMI/SDI Output: Encoding Settings

Setting	Options	Description
Video Format	1080P60, 1080P50, 1080P30, 1080P25, 720P60, 720P50	Sets the resolution and frame rate of the HDMI/SDI physical video output.

Click Apply to save changes. Click Refresh to reload the current values from the camera.

note

Changing the video format requires the camera to be rebooted for the changes to take effect.

Video Encoding Settings

Global encoding settings that apply across all IP streams.

Setting	Options	Description
Encoding Profile	Base, Main, High	Sets the H.264 encoding profile. Base offers the widest compatibility with legacy devices. Main is the recommended default. Main provides a balance between compatibility and compression efficiency. High provides the best compression efficiency for modern systems.
Video Templates	Low, Medium, High	Quick presets that apply a balanced combination of resolution, bitrate, and frame rate to all streams.

PTZ Stream: Encoding Settings

The primary IP stream from the PTZ camera. This is the main high-quality output used for streaming, recording, and monitoring.

Setting	Options	Description
Encoding Protocol	H264, H265	Video compression codec. H.264 provides broad compatibility, while H.265 provides higher efficiency but requires a paid Windows plug-in to pull the stream in.
Resolution	640x360, HD720, 1080P	Output resolution for the PTZ stream.
Video Frame Rate	1–60 fps	Frames per second.
Bit Rate (Kbps)	Numeric	Target bitrate in kilobits per second.
Bit Rate Control	CBR, VBR	CBR (Constant Bitrate) is ideal for live streaming. VBR (Variable Bitrate) is ideal for recording.
I Key Frame Interval	Numeric	Defines how frequently keyframes are transmitted. Lower values improve seek accuracy but increase bandwidth.

Reference Stream: Encoding Settings

The secondary stream from the wide-angle reference camera. Typically used for auto-tracking analysis and monitoring.

Setting	Options	Description
Encoding Protocol	H264, H265	Video compression codec. H.265 provides higher efficiency but requires compatible decoders.
Resolution	640x360, HD720	Output resolution for the reference stream.
Video Frame Rate	1–30 fps	Frames per second.
Bit Rate (Kbps)	Numeric	Target bitrate in kilobits per second.
Bit Rate Control	CBR, VBR	Constant or Variable bitrate mode.
I Key Frame Interval	Numeric	Defines how frequently keyframes are transmitted. Lower values improve seek accuracy but increase bandwidth.

Stream 3: Encoding Settings

A third IP stream available for additional monitoring, recording, or integration.

Setting	Options	Description
Encoding Protocol	H264, H265	Video compression codec. H.265 provides higher efficiency but requires compatible decoders.
