The ALF-IPK1HD is a 4K networked AV over IP decoder adopting the latest H.265 compression. The decoder can be configured in an IP video matrix or video wall setup using the VDirector mobile app (IOS and Android). The unit works easily with an Ethernet switch, no need to configure IP’s; real plug and play solution. Supports high-efficiency H.264/265 video codec with MPEG4-AAC and LPCM stereo audio. Built-in scaler for fast and seamless switching. RS-232 route follows the switching of video source.
INPUT: 1 x LAN (PoE) OUTPUT: 1 x HDMI, 1 x Line out, 1 x RS-232
Must be used with Gigabit network switches and CAT6 shielded cables are recommended.

Start-up procedure when using POE
Firstly, connect the CAT6 cable from the POE switch to the AV over IP Decoder.
Secondly, connect the HDMI cable.

|Can the app run on an IOS and Android devices?||Yes, the VDirector app is available for IOS and Android on the app stores.|
|Control API Telnet Port number||This uses a Telnet session on port 24 that communicates to each receiver. This means that you would need a “control processor” that has a changeable port number because Telnet is usually port 23. It would not be an issue for most control processors but maybe not on all the DSP’s.|
|Video wall Limitations||The limit on the app is an 8×8 video wall. Unfortunately, you can’t easily change from a video wall back to single decoders or Picture-in-picture. Once you create the video wall, the decoders that form part of the wall will disappear from the list and be replaced by a single video wall. This can be deleted and broken up to single displays and rebuilt but this is not a preset that can just be recalled.
It is possible to do a 2×1 videowall but, it does affect the aspect ratio.
|Network switch recommendations||The ALF-IP2HE and IP2HD use unicast where most AV over IP devices use Multicast. Because these units do not use multicast you don’t require a managed switch or IGMP.
We recommend a 1G POE switch and unmanaged switches works well for standalone system but also works with managed switches. If it is on a corporate network, we would suggest using a VLAN to avoid issues.
Each stream has an average bandwidth of 5Mbps and a peak of 20Mbps. Because it uses unicast, each decoder counts as a stream and a maximum of 50 decoders can stream from a single encoder to adhere to the 20Mbps stream peak (20Mb/s x 50 streams = ±1Gbps)
To avoid bottlenecks, especially in a system with flexible routing, a 10G link between switches would be best practice.
For POE requirements, max consumption is 5/6W each but like with amplifiers and speakers, a bit of headroom (20%) would be best practice.
|Latency||The latency from HDMI input to HDMI output is around 200ms.|
|Compression algorithms||The encoders use H.265 instead of H.264 and is a significant improvement on compression.|
|Size of matrix limit||50 Decoders receiving the same stream from a single encoder is a safe limit. There is no limit on the number of encoders in a system.|
|What is the ALF-IP2HD?||It is a network AV over IP decoder which works with the ALF-IP2HE.|
|How do I configure the ALF-IP2HD on the network?||There is no need for configuration, “plug and play” through network switch.|
|How do I set up the encoder to display on the video wall?||Through the VDirector app.|
|How many decoders can I use with a single encoder?||No more than 50 decoders to an Encoder.|
|Is RS232 supported?||Yes, RS232 and audio routing will always follow the video route.|
|Does the unit pass CEC?||No, it does not pass CEC from Encoder to Decoder but power on / off CEC commands can be done via the app.|
|The device is not switching on via PoE, how do I resolve this?||The display and network switch need to be grounded on the same circuit.|
