What is the main purpose of HDMI video encoder?

It’s primarily used for encoding audio and video from HDMI into network signal. The applicable industries are video surveillance like monitoring desktop of PC, live broadcasting and IPTV etc.

Which NVRs can it be compatible with?

The encoder can be compatible with NVRs from Hikvision & Dahua by private protocol and it’s H.265 recording. But for NVRs from other brands, it can only be accessed by ONVIF protocol. Please note that NVR recording usually use audio by G.711, therefore it’s necessary to set G.711 for encoder, then it can be accessed by NVR. Rare NVRs can be compatible with AAC, like TP-LINK.

What are commonly used addresses?

TS streaming media addresses:

• http://192.168.1.120:80/ts/0 (main stream)

• http://192.168.1.120:80/ts/1 (sub stream)

RTSP streaming media addresses:

• rtsp://192.168.1.120:554/live/0 (main stream)

• rtsp://192.168.1.120:554/live/1 (sub stream)

UDP address:

• udp://@224.1.2.3:10000

Why are settings set in IE (Internet Explorer) not saved?

It’s necessary to clear cache after setting the parameters in IE, or else all settings will not be valid; If you wouldn’t like to clear cache, it’s recommended to use Google Chrome instead, it will be valid immediately after clicking Save button. How should we clear cache in IE? Please see 1.3 or below screenshot:

When can we use H.265 encoding?

In video surveillance, H.265 encoding can be used when connecting to NVRs from Hikvision and Dahua. Under network transmission, it’s no problem to use H.265 encoding only when streaming video by protocols of TS, RTSP and UDP.

Why can we use only H.264 when live broadcasting? When can we use H.265 to do live broadcasting?

Currently RTMP standard protocol itself support H.264 only and Adobe already announced previously that it will be no more updates and maintenances for RTMP, that’s why H.265 is not available for RTMP. But it’s no problem for TS to do live broadcasting under H.265 encoding, which can be used for IPTV etc. however, the corresponding streaming media servers should be established by customers themselves. Generally, RTMP will be widely used for common live streaming platforms while TS stream will be used for private or self-established streaming platforms like IPTV.

Can video and audio be encoded by encoder simultaneously?

Yes, it can

How many seconds will be delayed when encoding?

Around 200ms

What is the lowest voltage for the encoder?

12V, it’s recommended to use DC12V 2A power adapter.

Can this encoder be powered by PoE?

Yes, HDMI video encoder with built-in POE can be powered directly by standard PoE switch(48W); But for basic encoders, you can also buy one POE splitter which get it powered by PoE.

How does data of the encoder go?

Video & audio will be input from HDMI and output by RJ45, that’s why the primary purpose of encoder is to convert HDMI signal into IP signal and transmit it out.

What is the maximum frames per second for this encoder?

Hi3516D can reach 1080P@50fps while Hi3516A 1080P@60fps

How should we insert LOGO when streaming?

Insert LOGO from Setting->Video/Audio->OSD->Picture osd via Google Chrome. Also LOGO in 200*200 & JPG only can be supported.

Which live streaming platforms can be supported?

YouTube, Facebook Live, Wowza Streaming Engine, Twitch, USTREAM, LiveStream, Wirecast, vMix etc.

What is maximum power consumption?

What is maximum power consumption?

How many channels can be supported?

One channel only.

Which operating systems does IPCManager not support?

XP & Win7 as the maintenance services are already stopped by Microsoft, therefore we won’t do more update and support.

Does this encoder support video input by VGA, SDI, CVBS?

There is only one HDMI port for this encoder which doesn’t support video input by SDI and CVBS. But for VGA, you can buy one VGA to HDMI converter cable. For sure, if needed, we can help you with that.

Can we use the Multicast either?

Yes, it can be set from Setting->Network->Multicast.

How many languages can be supported by default for UI?

Only 2 by default: Simplified Chinese and English. And it can automatically recognize your system language and select languages accordingly.

Can we stream live video simultaneously for main and sub stream?

Yes, but it’s necessary to set RTMP addresses respectively.

What is the main difference for main stream and sub stream?

Main stream means higher resolution, primarily used for CCTV surveillance while sub stream means lower resolution for network transmission.

Can live broadcast and surveillance be used simultaneously?

Yes, RTMP protocol will be used for live streaming while RTSP for surveillance, so it won’t be affected when simultaneously used.

Which kind of NVR can support live streaming and surveillance as well as sound?

As far as we learned, only NVR from TP-Link can support AAC, while traditional manufacturers only support G.711, not AAC because of intellectual property. Besides, right now our encoder can be compatible with Hikvision’s NVR & CMS (iVMS-4200) and Dahua’s NVR & CMS (SmartPSS) by private Protocol.
