Hollyview Cosmo C1 Wireless HDMI/SDI Video Transmission System, 40ms Latency 1000ft Range 1080P 5G USB Direct Live Stream, Wireless Video Audio Image Transmitter Receiver for DSLR Mirrorless Camera

Having used a number of the previous Hollyland products over the last couple of years I was really intrigued when the C1 was launched as the published range was an outstanding 1000 ft . Plus some of the additional features like auto channel switching and direct usb streaming from the receiver to usb connection on computer. (I was a little sceptical of the last point as I have never been able to get it to work as advertised on the previous Mars 400s pro)I have only been using it a couple of weeks now but must say how impressed I am with this new model for a number off reasons.Firstly the picture quality and near non existent latency is outstanding. We use this set on one of our roaming cameras and the picture quality is almost indistinguishable from the other cabled camera feeds we use. This really helps in a live mix situation.Secondly the additional range means we have now been able to connect in places where we have been previously limited. I don’t expect to quite get to the 1000 ft range especially in solid brick listed buildings where we often stream, but the additional range means that we have stayed connected where previously would have lost connection for lesser distances- the difference is huge.Thirdly the USB stream pull actually worked for us on this model which is a significant gain, the one thing we discovered was that we could not get USB C to USB C to work but using USB c to USB A and then the included usb a to USB c adapter included with pack worked perfectly (not sure why or if its just our set up)The ruggedised case it comes with is a great bonus so you can safely pack away and keep all the accessories together is an added bonus.The C1 cost more than than the previous 400s pro and Cosmo 600 but in my opinion was worth the extra investment because of the additional reach, reliability and picture quality. Will come back to update as we continue to use this over the next few months but so far so good. - Well done Hollyland. Just an additional note I have said this previously but I have found the technical support and customer service team outstanding in particular Livia who helped us get through some of the initial issues in the early days of using Holllyland products -thank you!

We like this product as it allows us to freely film without being cabled to a loom...

This is just what I needed for my short film.Long distance and run and gun style shooting kept the director happy.

Very disappointed with the hollyland transmitters, for products that are this expensive they are prone to stop working after 2 years with health & safety risks and we’ve had smoke coming out of the transmitter after switching on. We have lost corporate work over the product being defective and neither hollyland or amazon will take responsibility for this. After getting in touch with the company both on email and the Instagram page we received no customer support for the product. Do not buy this. Hollyland and Amazon are refusing to discuss this issue with us after a clear manufacturing fault as we’re only a couple months outside the warranty. This is unacceptable as we paid £899 at the time of purchase and the product has only been used on a couple of jobs prior to this happening. Besides this it has been kept safely in the pelicase it arrived in. They clearly do not care about their customers or products and have no regard for the products being defective.
