IDX System Technology CW-3 overview

  • 1Description

The CW-3 3G-SDI Wireless Video Transmission System from IDX is able to transmit Full HD 1080p video at up to 164' line-of-sight with no quality loss and less than 1 ms latency. It can transmit even further; up to 380' line-of-sight (depending on conditions), but at this extended range some loss in quality may be experienced. It supports 3G- and HD-SDI video signals at up to 1080p60 with 4:2:2, 10-bit color. AC adapters are induced for the transmitter (Tx) and receiver (Rx), or they can be powered from a 7 to 17VDC external source, such as a video battery system with PowerTap. A 1/4"-20 adapter is included for mounting the transmitter on a camera.

Utilizes WHDI (MIMO/OFDM) wireless technology
Operates on 5 GHz frequency band (license free)
Zero frame delay; less than 1ms latency
Dynamic Frequency Selection (DFS) operates on less congested channels for optimal performance
GPI output on TX for tally
PowerTap cables, SDI cables, AC adapters, and 1/4"-20 mounting adapter all included

    IDX System Technology CW-3 reviews

    CW-3 3G-SDI Wireless Video Transmission System is rated 3.4 out of 5 by 10.
    Rated 3 out of 5 by from Does not work in 23.98psf ! Works well, but does not work on 23.98psf. Many cameras, including the F5 and many xdcams, only output 23.98psf when recording 24p.

    Rated 5 out of 5 by from It works right out of the box! This is a plug and play unit, with no signal lost or latency. Sending signal from a JVC camera sdi output to a Datavideo 2200. For the price is a no brainer. My only complain is it does not come with a battery and it only includes 1 power supply. We used a standard 12vdc p/s we had laying around and voila instant wireless video.

    Rated 3 out of 5 by from Okay under the right conditions I've had a few issues with my CW-3... (1) Reliability of the signal: If transmitter and receiver are close to one another, the signal seems to pretty much be rock-solid. But if there are obstacles in the way or there is much distance between themthe signal will drop and then take 30-60 seconds at a minimum to resync once they are back in line-of-sight of one another. Even then it doesn't always resync on its own and requires a reboot of the receiver and/or transmitter. (2) These don't handle 3G-SDI very well. They officially support 3G Level A, but the output of the receiver doesn't comply with SMPTE standards very well and I have to run the signal through a Decimator MD-HX to clean it up so other equipment can use it. None of my other gear will recognize the output signal at all otherwise. I've been working with IDX Support on the issue and they think they might be able to fix this with a future firmware update, though they aren't promising that, and I'm not holding my breath. (3) Oddly, if I try to transmit a signal passing through my Decimator devices, the transmitter won't recognize the signal at all, no matter what resolution and frame rate. Which means they are picky about what 3G signals they will support. I haven't had any issues with my cameras, but there's no guarantee that a different camera won't have issues. Overall it seems like these have a few bugs in them that need to be worked out.

    Rated 3 out of 5 by from Dual camera blues We ordered 2 of these units and mounted them on a dual directors cage for 2 camera monitoring. Pretty sweet rig!. We had already done this with our Paralinx units and it worked beautifully for years. These units work well too... one at a time. They work straight out of the box and deliver great image quality. Our problem began when we used two in tandem. For some reason when our cameras get closer than 20 feet from one another one of the units loses its picture. When the cameras separate it comes back. Its not consistent which unit loses picture, but one always does. The folks at IDX suggest that the issue is related to the receivers on the cage being too close together. Nothing we can do there. So for the time being we can use one or the other but not both at the same time unless the cameras are far apart. SO... if you only need one transmitter receiver combo, I give it 5 stars. Easy setup, great image quality. Two thumbs up! If you need to run two or more at a time, beware.

    Rated 5 out of 5 by from Great Investment We were so hesitant. This is almost bottom of the line pricing, and we didn't have our hopes up, but it works really, really well. We plugged it into our P2 Panasonic AG-HPX300P (circa 2007) and were floored with the quality and latency (or lack thereof). Our walls really took away the signal, but we LOVE it for our house of worship.

    Rated 5 out of 5 by from great product...even using multiple units at the same time. We have two of these and they work really great! We use them on the downstage edge of our stage for live video on our hand held cameras. We use them in a wi fi heavy environment with both 2.4 and 5g networks and they have been rock solid. Range is doesn't go through walls perfect but it is surprising. I've used these and the Teredeks and these are better and cheaper.

    Rated 3 out of 5 by from IDX CW3 got one today and tried it in an indoor environment. managed to get thru a maximum of 2 reinforced concrete wall, each 100mm thick at around 8metres range. Will try outdoor tomorrow.

    Rated 1 out of 5 by from Cut your expected Transmission by half! I purchased this unit with the mindset that it could do 164' of wireless transmission. I could not be more incorrect. I tested line of sight indoor and outdoor with about 75' before it would start digital tiling. It was not impressive. I tried different sitations and even tried through walls. That lasted about 30-40'. This was no better than a $ wireless HDMI unit from mononprice. I also found the unit to be built with a plastic feel, which didn't sit well with me for long-term durability. I ended up going with a Teradek 300 unit. It was built with metal housing, and seems like it will withstand much more industrial use. It's the first unit I have bought from teradek and is significantly more expensive, but it did the job. I could get 150' before it would break up with tiling. The irony here is that the Teradek 300 was rated for 300' of wireless. word to the wise, the claims of distance are most likely tested under minimal interference conditions. Whenever you want to go wireless, cut the 'claimed distance' in half and that will be your real distance.
