Cosmo400: Overview
Cosmo400 Wireless HDMI/SDI Transmission System utilize today's most advanced wireless video transmission technology, which could help the filmmaker get rid of the traditional wired shooting. It supports both HDMI & SDI input and output with
working distance up to 400ft and operates over the unlicensed 5G frequency band and transmits 4;2:2 video at less than 1 ms of delay no compression, offering flawless image quality.
Distance & Description
Line of sight 400ft transmission distance with HD 1080p60, connecting distance over 400ft. Less than 1 millisecond of delay. No compression.
In Line of Sight, the transmission distance could reach 400ft with best image quality HD 1080p60. While the distance boost over 400ft Transmitter and Receiver still could be connected but with the lower image output. The latency is less
than 1 millisecond, no compression.
Performance Description
• Unlicensed 5GHz & 10 Channels Optional
• Multicast support
• 1 transmitter to multi receivers, max 4 sets in in one location
Application
Connect camera SDI or HDMI output to transmitter SDI or HDMI input port and the transmitter can fixed in hot-shoe port of the camera. Connect HDMI or SDI output

| Hollyland Cosmo400 Wireless Video Transmitter Review |
 |
Jason - 01/09/2017
I have been on the research to get my Professional Video transmission for both range 100 m to 300m for long. as I have applications for both short and longer range transmission. I needed times to keep enough money to get this gear for my
jobs. Thus I was really care about my money to get the best value product. Sadly due to technology restriction I could not find one which allow me to transmit without having line of Sight for some scenario. With that I have to follow the
rule to get my best coverage without dropping much of the signal.
With that requirement in mind, I've managed to find some, Thanks to Friends recommendation and web info and subsequently filtered it to only 2 for ease of decision making, The 2 brands, namely Ghost eye and Hollyland. And I was in the
cross road for which one to get. I needed to do something's to get the right one. (Comparing Ghosteye versus Hollyland) After some efforts of research, I have discovered something's very interesting. And I thought I would like to share this
on this post.
Long story short, My final decision was to get Hollyland Cosmo 400 (120M) and
Cosmo 1000 (300m) from Expandore instead of buying online for Ghost eye, Here
are the reasons.
• My Friends have bought both 2 from Cinegear Ghost Eye from overseas on-line shop, namely the Ghosteye Kit 150m and Ghosteye kit 300m, upon my request he allowed me to bring to the shop to make the comparison with his presence.
• Cosmetically both brands like similar ( I would say identical ) except for the brand, of course.
• However it seems that Ghost eye was having longer transmission range as per their specification 150m vs 120m, and 350m vs 300m, I thus presumed that the price different and thus it is cheaper for Hollyland.
• To Convince myself further, Thanks to the shop, the allowed us to do the transmission distance test under the same conditions. but both performed nearly same under the same distance
• I went one step further and Upon my deeper finding and research on web site and including calling the China Counterpart, to my surprise I found out something else. That the original maker of both product seems to be the from the same source, ie Hollyland is the original maker.
• I thus asked many questions including are both brands having the same spec and also why for the same product , the specification is varied and that is what I got.
• It was quite sure by then that both brands are produced the same way using the same component and chip in the same factory, the manufacturer by fast the standard has to state its Specification to its client and the consumers. While
the brand owner has it rights to state the specification that the product could stretch .
• I further asked the maker, could their 120m Gear could do the same Ghoseye did for 150m So for the 300m and 350m. Again the answer given was positive but under certain conditions. The maker further stated that they would prefer to stay the
specification with safety factor built in rather that stretching it, as under circumstance it might not performs according to the requirement. IT is better to be in the state of under- promised and over-delivered
• The last question I had asked was, can the maker has control over the specification specified by the client which was different from the original specification , they would not want to comment further.
• Being a consumer, it is worth the while to do some research to get the product that deserved the value. By doing what I was doing it saved me close to SGD 800/= and SGD 1,200 respectively

Ghost Eye vs Hollyland Cosmo
Jason thanks you for the information. In fact I faced the same dilemma.
I was proposing Ghost eye to a worship place, however due to some "uncomfortable" reason it was rejected as the users did not like to have the "Holly event" to be transmitted thru "Ghost xxx". On the contrary, the
Hollyland sound more acceptable. The reason for the acceptance has nothing to do with the Technology but the name.
After reading Jason's sharing, my problem solved. The Hollyland Cosmo 400 work
perfectly for us, we have not yet experienced any signal drop as long as I am keeping both wireless transmitter and receiver with line of sight. Best of all it support 1080 /60P.
Despite the fact that Both Ghosteye and Hollyland are produced by the same factory, the price point varied, I have enjoyed great saving.
The Cinegear should consider to re-brand it ghosteye to be may be Gold eye... Just a suggestion.

Loss signal – Blocked by Building – No line of sight
I have deployed the Hollyland 1000 Cosmo in my recent events, and I was given the most difficult assignment to transmit the Wireless Video. The
horizontal distance between the RX and TX is about 250m. However there was a building 30m away which block the transmission in line of sight, there is no way to get the signal except that to deploy the receiver 30 m away from the
controller room.
I used SDI cable to tap the signal from the receiver and laid the cable for about 40m till the controller room. As now both RX and TX are in alignment, the signal is perfect. I was able to receive the signal at 1080/60P with almost no
latency and good quality of HD video. Thanks to Hollyland Cosmo. This product work as well as its competitor which cost more than USD 500 more. |
