IDX System Technology CW-1 overview

  • 1Description

The IDX CW-1 Wireless HDMI Video Transmission System is a wireless transmitter/receiver set that transmits video signals up to 1080i60 uncompressed, with embedded audio, on the license-free 5 GHz frequency band. It supports transmissions up to 300 ft line-of-sight with less than 1 ms latency in interference-free environments, and 30 to 150 ft line-of-sight in average environments. It uses WHDI smart antenna transmission technology.

The transmitter has a stick-type form factor and can be plugged directly into a camera's HDMI output. If the output is somehow blocked, you can use an included right-angled HDMI adapter or an HDMI cable to connect the two. An HDMI cable comes with the kit but is intended for use with the receiver. The receiver outputs video by HDMI to HDMI recorders or directly to an HDMI display.

An AC power adapter is included for the receiver, and a USB-to-USB cable is included for powering the transmitter off any USB power source, such as a computer. However, both units are best off powered by optional battery adapters -- model #s A-CWJ-TX/A-CWJ-RX and A-CWS-TX/A-CWS-RX. These adapters accept JVC SSL-JVC50 and Sony L series batteries and connect to TX/RX via USB outputs.

    IDX System Technology CW-1 reviews

    CW-1 Wireless HDMI Video Transmission System is rated 4.1 out of 5 by 35.
    Rated 1 out of 5 by from Failed when needed Sorry for the one star. I hate to be so critical but this item was tested on stage the day before a live IMAG shoot and worked great. Probably sent the 1080 signal 80 feet and through heavy doors. Fast forward one day. I walk on the same stage with the same steadycam but now I am about 40 feet closer to the receiver. And there is no signal. So here I am on stage with Chaka Khan shooting live steadycam IMAG and NOTHING on screen. I leave stage and walk to the receiver and it connects when I am 5 feet away. then I walk back down a long hall (behind a wall) and it disconnects again. So I am back at the stage and once again, no signal. This is about 60 feet LOS to the receiver.

    Rated 4 out of 5 by from updating my 2/17/14 review okay I have now used this unit many times. it has developed problems with linking. I have returned the old unit for repair and bought a new one from BH yesterday because I have to use it next week. The fellow at IDX that I talked to this week says some units have had internal board problems. I am hoping that I don't have this same problem with the new one. Also to follow up on my complaint about the VGA adaptors, I have discovered after talking with Sony about my camera the nx5u, that to make the output work with VGA, the hdmi output on the camera has to be set to 720, not 1080. now the vga adaptor works fine. so the problem was NOT with the IDX unit. I will let you know if any problems develop with the new unit I'm using next week

    Rated 4 out of 5 by from Great Product but needs some ACC to work well. Quick review: Pros: Cheap Small Good range for price (100m line of sight open terrain, 50m inside trees) Same product as Paralinx Arrow, uses same accessories Cons: No usb to 3.5mm barrel cable for the RX end (comes with wall adapter only), you will need to source the same cable used for the paralinx arrow (identical devices) to power this device from usb (like a USB power bank. HDMI only Slow reconnection times when at the outer ring of reception Suffers from camera RF interference (needs to be lifted up away from camera as much as possible to maximize range). Cameras like the Red Epic produce a lot of RF. Tips: Buy a Paralinx shield for the TX otherwise the TX is very easy to damage (fits perfectly as the same product just differently branded). Needs 5v 2 amp power source for TX and RX for maximum range, less amps will effect the range you can get. TX can be run from a SmallHD DP4 from the usb power out on DP4 (turn on in DP4 Menu), you will need a mini usb to mini usb cable. Limits range as DP4 does not output 2 amps but works for short range applications. Best TX and RX orientation is lying flat opposed to pointing up towards the sky as many people may think.

    Rated 5 out of 5 by from Wonderful Package for the Price This is my first wireless HD setup. I couldn't be happier. I always thought that high quality wireless HD was going to cost over $2000, but this manages to deliver for a fraction of the cost. The quality is very good. There appears to be no added noise at all. Now, unfortunately, it doesn't have a huge range. With line of sight it works for about 100-150 feet. Through walls it works about 60 feet. I am a DP, and on set I can run this off my camera to the DIT who can then add a 3D LUT live and then output to the director's monitor. Also works great for flying steadicam.

    Rated 4 out of 5 by from product is okay I do wireless video live simulcasts for events: weddings, bar mitzvah, meetings, etc. I have found this unit to be very easy to use and it works great but there some things you need to know. It only has one output: an hdmi output. I have found that not all the places that I want to use it at has hdmi inputs. some have composite or component and a few have vga. I have bought a few hdmi to vga converters from b&h and have not had one work yet. I think the inputs think I'm transmitting hdcp video and they won't let the signal through. I am at a loss to find a converter that works. i welcome all ideas from people. I am using this cw-1 with a sony nx5u. I would have given this 5 stars if the video worked with all inputs

    Rated 5 out of 5 by from My first HD Wireless Experience I was about to enter my 8th 48 hour film competition and wanted to be able to board cast my camera HD signals to remote monitors. After read various product reviews i decided to purchase two sets of the CW-1 to hook up to my rigs, which consists of the following: Nikon D810 DSLR feeding HD signal to a Atomos Recorder, then out to a Marshall monitor. The CW-1 unit was then connect to the Marshall Monitor. The receiver was mounted on to small HD monitor/tv. The overall performance of the signal was great. I even used two of these at the small time feeding signal from separate rides to operate montitors.

    Rated 4 out of 5 by from Not a bad little device! I recently bought this device and used it at a live mas crowd event. Before the place was crowded, i tested it and it worked great (good video HD and ausio). I covered a distance of about 200-250ft. But when the place got crowded, then the signal started breaking up and even disappearing. I have another event this weekend and will try to put the receiver on a pole about 12ft tall. i will report back on this experiment. but all-in-all, it's worth the price.

    Rated 5 out of 5 by from All good I use it for live sports events and it does everything it says. Got the biggest battery I could find - 10400mAh Sony BBCB - 406 and so far I have not been able to run it down past 75% full - that was around 3 hours working constantly. So Gold Star - had my doubts but am pleased with results - links in quick and seems to work up to 100m.
