As a comparison, the average delay over HDMI for the Hollyland COSMO C1 when doing the exact same test was 76ms.

The transmitter and receiver provide multiple power options, including a DC barrel input, an L-series battery plate, and a USB Type-C input. Due to its low-power, fanless design, an NP-970 battery can provide up to 12 hours of runtime for each unit. Dual-channel transmission makes the CineEye 2S Pro highly resistant to outside interference and ensures that a strong, high-quality signal will be delivered over the 1200′ line-of-sight distance. The affordable wireless video space is getting crowded These LCD displays are designed to simplify mounting and alignment with a unique front-access mounting system that allows for precise alignment, in-wall servicing, and an extremely low, ADA-compliant profile depth from the wall (as low as 3.6”). When it was set to HQ transmission it recorded an average delay of 85.66ms when outputting from the RX to a monitor and 96.66ms when receiving a signal on the Accsoon App. You can also use the CineView HE as a wireless webcam device, however, the image does get flipped and I found that the colors being shown did not reflect those being seen on my camera. There is also quite a large image delay. The weight and footprint, especially if you are using the TX with a Sony NP battery, do make the CineView HE feel quite big on small-sized mirrorless hybrid cameras, however, just about every other competing product on the market features a similar size and form factor.

One transmitter can stream to up to four iOS or Android devices. You can use a combination of Android or iOS devices, as long as you aren’t using any more than four.

Look, if you are just using your wireless system for monitoring and nothing else, then latency is not going to be a big issue. However, If you want to do remote focus control then you really should be looking at an uncompressed wireless video system that has zero latency.

I also tested the Accsoon CineEye 2S Pro Wireless Video Transmitter & Receiver when using HDMI and found that it had an average latency of 46ms when viewing images on a monitor connected to the RX unit when the TX was set to Normal transmission. Real-world performance Accsoon does now face very stiff competition from a wide array of affordable wireless video systems that have come to market from various manufacturers. What it is and what it isn’t Yes, this kind of range for a budget system is impressive, however, it is susceptible to interference and break up if anything gets between your camera and the person who is monitoring. It was good to see that both the app and the RX unit both had a good operating range. The app is more suceptable to break up and signal loss than the RX unit. A UVC output via USB-C allows direct connection of the CineView HE receiver to a computer so you can livestream HD images. This helps to simplify the whole process of going live on YouTube, TikTok and other RTMP streaming platforms. This is the same capability as what Hollyland features in its COSMO C1. The CineView HE receiver can also be used with vision mixers with UVC or HDMI inputs for increased flexibility.

At power on, CineView HE will automatically select the best channel for audio and video transmission. The Dual-Band transmission technology will further improve CineView HE’s anti-interference capability to ensure that the high-quality audio and FHD video can be transmitted with nearly undetectable latency via its reliable dual-band transmission signals.

I did find that after you make the change to the Group on both the TX and RX units and you re-boot both of them it does take a little while for the RX to find the same channel that the TX is transmitting on. UVC Direct Streaming

PCC includes the ability to perform basic measurement functions for motion analysis. The results can be viewed immediately and then automatically saved to a spreadsheet for review. If you want to have the HDMI input on the same side as the HDMI output of your mirrorless hybrid, then you can simply just face the front of TX unit forward. The only caveat with doing this is that you can’t see the screen anymore. What do you get? When it was set to Speed transmission it recorded an average delay of 59.33ms when outputting from the RX to a monitor and 70.66ms when receiving a signal on the Accsoon App.

Size & Design

Use up to four receiving devices at the same time in any combination with the same CineView HE transmitter. Connect your choice of CineView receivers and iOS/Android devices using the Accsoon Go app all at once. Multiple people monitoring on-set has never been easier. Image delay can be a problem with HDMI based devices, but it really depends on the camera you are using. Some cameras have horrible image delay over HDMI, while others are really good. Cameras with SDI tend to have a lot better latency, but when you are dealing with wireless image transmission devices that send a compressed signal over Wi-Fi then there won’t be a massive difference between HDMI and SDI delay, although this would depend on the camera. Phantom Camera Control (PCC) is the main software application that allows users to get the most out of Phantom cameras. Fine-tune the resolution, frame rate, exposure, memory segmentation, trigger modes and automatic functions prior to recording. PCC also makes it easy to work with synchronized cameras, manage Phantom Cine raw files and convert files to the format that makes sense for the final project.
