Reviews
iPhone monitoring &
live streaming FAQs.
How can I use my iPhone as a camera monitor?
Connect your camera’s HDMI output to SeeMo 4K, connect a compatible iPhone using the appropriate cable, power the adapter with a compatible NP-F battery and open Accsoon SEE. Your iPhone displays the camera feed with monitoring tools such as waveform, zebra, false color and LUTs. Check device and cable compatibility before buying.
Can I use an iPad as an external camera monitor?
Yes. SeeMo 4K works with compatible iPads through the Accsoon SEE app. An iPad gives you a larger screen for reviewing framing and focus. Check the compatibility chart and the required connection cable for your iPad.
Can I connect a DSLR or mirrorless camera to my iPhone?
You can connect a camera with a supported HDMI video output to SeeMo 4K and use a compatible iPhone or iPad for monitoring. Check the camera’s HDMI output format against the specifications. A compatible HDMI cable and the correct iOS connection cable are required.
How do I live stream my camera’s HDMI feed from an iPhone?
Connect the HDMI camera to SeeMo 4K and your compatible iPhone, then open Accsoon SEE. Configure the app for a supported SRT or RTMP destination and use the service’s stream settings to go live over your network connection. Check the destination’s requirements before a broadcast.
Can I stream my camera to YouTube, Twitch or Facebook Live?
Accsoon SEE supports SRT and RTMP streaming, including compatible workflows for YouTube, Twitch and Facebook Live. You need network access, an account with the destination service and its required live-stream settings. Platform availability and account requirements are controlled by each service.
Does 4K30 HDMI input mean my live stream is always 4K?
No. SeeMo 4K accepts supported HDMI inputs up to UHD 4K30. The recording or streaming configuration also depends on the app, iOS device, network and destination service. Do not treat the maximum HDMI input resolution as a guaranteed live-stream resolution.
Is SeeMo 4K a wireless HDMI transmitter?
SeeMo 4K connects an HDMI video source to a compatible iOS device by cable. It is an HDMI-to-iPhone/iPad monitoring and video capture adapter. Internet live streaming uses the connected device’s network connection; it does not make the camera-to-phone HDMI connection wireless.
Does this SeeMo 4K work with Android phones?
This is the iOS version for compatible iPhones and iPads. SeeMo 4K for Android is a separate product. Check the device compatibility chart and cable requirements before ordering.
Can I record camera video on my iPhone or iPad?
Yes. Accsoon SEE supports H.264 recording on the connected iOS device for mobile editing and sharing. This is separate from your camera’s internal recording. The SD card reader supports file-access and backup workflows; do not assume standalone direct-to-card recording.
Can SeeMo 4K power my iPhone or iPad?
SeeMo 4K can supply power to a connected iPhone or iPad. The listed USB-C power output is 5V / 3A, and the device uses an NP-F battery. Confirm your cables, battery and accessory requirements before ordering.
