Do you know what isn’t any fun? Finding the perfect spot for your sound cart, getting all antennas deployed, running (and making safe) a cable to video village so that you can get your monitors up, and then having video village move every shot or two which causes you to constantly have to re run the cables. Don’t you just wish that there was a low cost, high performance wireless video solution so that you can keep your video cable in that perfect coil that probably took you hours to perfect?
Well, rejoice! Newcomer Accsoon has got you covered!
Transmitting on the 5ghz WiFi band, the CineEye can feed high grade video to 3 Android or iOS devices simultaneously. If that sounds familiar, it’s probably because you’ve heard of the Teradek Serv Pro. While the Serv Pro can operate on the 5ghz and 2.4ghz bands, as well as transmit to 10 devices simultaneously and use an SDI input, it is only compatible with iOS devices. More than half of the smart phone world uses android devices, so that’s bad move in my book. So, in that department, the CineEye has a massive leg up. Not to mention the fact that the CineEye is equipped with an internal 4 hour battery.
The Serv Pro is also a lot more expensive at around $1800 USD. The CineEye on the other hand retails for a shocking $219 USD. Yes, the Serv Pro has more bells and whistles, no question. But, in the sound department we have to ask ourselves: “what do we need to accomplish on set?” Do we need 10 connections? Do we need both the 2.4ghz and 5ghz bands? Chances are that we don’t, but to each their own. And again, let’s not forget about the lack of Android support on the Serv Pro. That alone puts it out of the running for me.
Accsoon advertises a 100 meter transmission range with no obstructions. If you look at the range test in the video above, you can see an example of the excellent performance from the CineEye. Some might point out that such tests are loaded because we rarely are in perfect line of sight. That’s true, but how far are we from camera or video village in almost all cases? Not even close to that far. Most often, we are stationed in the next room and the CineEye will punch through even 3 walls no sweat (assuming that they aren’t lead lined). On the multiple projects during which I have used the CineEye, it has performed extremely well without dropouts or lag.
The physical design of the CineEye is nice and sleek. There is a single HDMI port, a power button, a USB-C port for charging, and a threaded mounting hole. It’s kind of all that you need on a smaller unit like this. There are also 4 LED indicator lights on the front panel to show the remaining battery.
To some, the lack of SDI port on the CineEye might seem like an issue. At most, its a minor inconvenience because of the myriad of SDI to HDMI converter options online in the $20 or $30 price range, like the one pictured above. They typically will operate on 5v power like the CineEye so you could use the same USB power bank to feed both units and give yourself a super easy setup to throw on the back of the video village monitor. This is the box that I like to use, but there are plenty out there. Pair those together and you have an incredibly low cost wireless video option, that utilizes the monitor thats already in your pocket.
The free App is simple and straightforward. You connect to the WiFi signal from the CineEye and then you hit the “on” button in the menu and there’s your video. As you can see from the screen shots above, you have access to a lot of great video tools that the sound engineers probably won’t need, but are nice to have. You also have the recording button in case you want to save a reference clip on your phone for later. In the menus, you can also change the WiFi frequency to a specific channel instead of Auto, which is good to have if you need to avoid other 5ghz transmissions in the area.
Wish List For A Future Version
If Accsoon creates another model of the CineEye down the line….. Say…. a “Pro” model….. *hint* *hint* *wink* *wink*, here are a few things that I feel would be nice to have.
- SDI input
- SDI/HDMI passthrough to feed other devices
- A bigger battery
- Longer transmission range
- SDI/HDMI cross convert on passthrough
- Support for more devices connected simultaneously
- A separate receiver unit which can feed an SDI or HDMI monitor (credit for this idea goes to Sound Mixer Jim Keaney)
Some of these might be lofty requests, but I want to note that I don’t feel that this device is deficient at all. This is a wish list for a higher model specifically, because at the CineEye‘s price point, it’s already doing a lot. The current model has an excellent place in the market where it is. The higher model would be for more advanced situations which need those extra bells and whistles, whereas for the majority of setups, the current CineEye will work great.
In summary, the CineEye is poised to bring high performance wireless video solutions to operators who, for monetary reasons, would previously not have had access to anything but a corded connection. It has a welcomed spot in my kit, giving me a video feed at the cart, and my Boom Operator a convenient frame guide for the microphone. You literally cannot go wrong with the CineEye and I recommend it to anyone needing to see the frame on set. Great job Accsoon, I look forward to seeing what you come up with next!

Just bought the CineEye, used it on 3 shoots, 2 of which it did not work well. So 1 of 3 is not a huge success rate. Wifi would break lock and then unit stops transmitting the SSID for its network so can’t rejoin it. It’s been a little frustrating to try to use on set. Not sure if related, but the two times it did not work we also had a Teradek wireless from camera in use, maybe there is some compatibility issues there.
It could be that there is a some interference from the teradek. But this type of issue was not something that I experienced. Perhaps check with customer support about this.
You can try to switch to the manual channel, and the 9 channels can be tested before finding a clean channel. If you are an Android phone, you can download the WIFI BOX, which is used to check the cleanliness of the channel.

Hola Jared, great articule,
Q, it work with 4 K or plus video forma, or it is just for HD?
It only takes in 720p or 1080p, however in almost all cases, the cameras will only feed 1080p out of their hdmi or sdi ports.
I just bought the CineEye, have not used it in real shoots as i am still organising a way to attach a Iphone5S to my bag. I do small rig documentaries, all need to be simple and small. Can’t wait to try it out!
A few comments about your wishlist for a next model.
An SDI and loop through is also my biggest request. To add another converter box to the mess on the camera’s is not something i look forward too.
I like your idea of a loop through annex converter from HDMI to SDI and vise versa.
Bigger battery and better range is something i am a bit reluctant to. I already worry about the size of the box as it is now . For smaller camera’s, this CineEye is already an addition to the weight. Look at your pic of the DSLR camera; if i was a DOP/operator i would not by very happy with a thing like that on my camera that has not a direct function for me. An SDI version with loops would already make it bigger, a bigger battery and more range would add even more. Maybe a replaceable battery would be an option. For now, the battery life is already too short for a day. The easiest solution to this would maybe be; buy two of these CineEye’s!
This “pro” model wish list would not be aimed at dslr shooters. It would be aimed at the larger productions which already use teradek systems attached to camera.
But on the subject of the DP, I’d say that this has huge uses. If you velcro the phone to the back of the cineeye, you have your bigger monitor right there on camera. Plus, the app gives you features that a dslr just doesn’t have. Like focus peaking, zebras, false color, and lut previews. It’s more helpful to a dslr shooter than probably any other user. In my opinion that is.
Yes, if SDI is added, the volume, weight and power consumption will increase. Now CINEEYE only uses one 18650 battery to do it for 4 hours. You can work with the charging treasure and keep working for a long time.
Most people, like myself, will use the cineeye with an external battery all the time. The internal battery is more of a backup for most users.
the CineEye seems to work much better with an external battery. I can watch the CineEye’s transmission power cycle up and down on internal battery power, whereas on external battery the transmission power is very stable. With only one device connected, the CineEye has been VERY stable in my initial testing. I had to play with the wifi channels to find the one that worked best for my location, but once I found the strongest signal the CineEye performed wonderfully. There is an issue with the recording function on iPad-the resulting video file is displayed with incorrect aspect ratio. And there’s currently no way to bypass the LUT other than to return to the app’s start screen and clear the current settings. Doing this also returns ALL settings to default, forcing user to re-select settings (center marker, ratio marker etc).
The app could use some improvement, but overall an excellent first release.
This thing is an absolute steal at $219. I use it on an iPad Mini that also acts as a smart slate (MovieSlate 8 synced to Tentacle via Bluetooth) and can switch back and forth between the 2 apps with no issues. Connecting more than 2 devices degrades the wifi signal too much, but with only one iOS device connected it performs well above its price point. Kudos Accsoon!
When your HDMI output is 1080I, the aspect ratio will be wrong when recording, because of the reason of interlaced scanning, but when your camera outputs 1080P, everything will be normal.
In the case you are sending a wireless audio signal to the camera, do you get an audio signal at your cellphone whenever there is playback?
There is no audio in the original Cineeye. However, I believe that there is audio in later models.
