Product Information

Having the ability to rig up a lightweight and compact TX unit to a camera so that producers, directors, clients, or even a sound recordist can see your images is really handy. Look, this is not a solution that will be suitable for everyone, but it is an affordable way for anyone to offer a wireless feed to clients or people they work with. Accsoon has forged a good reputation for making affordable wireless video kits that are well made, feature-rich, and most importantly, have reasonably low latency. The CineView HE certainly follows in those same footsteps and it is certainly worth looking at if you are in the market for an HDMI wireless video system that won’t break the bank. Since that time Accsoon has released a lot of different wireless video systems with different functionality at different price points. I have reviewed quite a few of them and they have generally performed well compared to the competition. As the TX unit has both an HDMI In and an HDMI Out you can loop through a video signal which is handy. How is it powered?

Vue Swansea has wheelchair access throughout the venue and in all screens. Access to the venue is through two sets of double doors: one set are push/pull; the other set is automatic. As a comparison, the average delay over HDMI for the Hollyland COSMO C1 when doing the exact same test was 76ms. The CineView HE Wireless Video Transmitter & Receiver both weigh 200 g / 7.05 oz (including the antennas). This makes them slightly lighter than both the CineEye 2S and CineEye 2 that weigh 213g / 7.5oz.There are stairs, escalators and a lift leading up to the main foyer where screens one to seven are located. There's step-free access to the wheelchair spaces and adjoining seats, and accessible toilets off the main foyer and on the upper floor. So what would happen if I suddenly changed the frame rate to 50p from 25p on my camera while the system was on? The Accsoon automatically recognized the change and I didn’t lose the image on my monitor. So what is the delay like over HDMI from the Kinefinity MAVO LF? I measured the delay average over a series of three tests when using the Accsoon Go app and outputting directly to a monitor from the RX unit. Below you can see the results when the system was set in all three transmission modes:

You can also choose what monitoring items you want to use. By selecting or deselecting these items you will only be able to see those items you have selected at the bottom of the screen. I do find it a little strange that the Add/Del section actually names the icons, but on the main screen they aren’t named. This does make choosing some of them a little confusing. I also found that if I attempted to use the CineView HE at the same time as another wireless video TX unit, that TX unit just overpowered the signal, and the CineView HE became unusable. This is something to just keep in mind. HDMI has inherent image dealy problems, and yes if you combine that along with one of the cheaper wireless video systems you can get a lot of latency. At the end of the day, there needs to be an acceptable limit that you are willing to tolerate. Delay on other similar systems The CineView HE TX and RX can be powered via a single Sony NP-F style battery. According to the company, a Sony NP-F970 battery can power the unit for up to 12 hours. I found the battery performance to be good and you can use the system for a whole shooting day without having to constantly worry about when the battery will run out. You need to clearly know that this system, and similar systems just like it, are not going to provide you with latency-free images. The results you are going to get will depend greatly on the camera you are using. In saying that, my testing showed that the latency is reasonably minimal. This is not a system you would want to pull focus with remotely. You need to clearly be aware that this isn’t a product that has been designed to compete with non-compressed, low latency systems.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 Depending on the mode you choose, the latency and the quality of the image will change. If you want the least latency then Speed Mode is the one you want to choose. If you want the best image quality then High-Quality Mode is what you should use. Normal Mode is essentially a middle ground compromise between the other two modes. The CineView HE can send up to 1080p60 over Dual-Band (2.4 GHz + 5 GHz). Accsoon claims that this wireless transmission technology means you never have to worry about video or audio drop or switch signal issues again. This is a very bold claim as I have used and reviewed countless similar systems and they all drop out. I will test this claim further down in the review.
