    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.

    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 ‘s 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 somethings to get the right one. (Comparing Ghosteye versus Hollyland)

    After some efforts of research ,I have discovered somethings very interesting. And I thought I would like to share this on this post.

    Long story short, My final decision was to get Hollyland Cosomo 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.
