Hollyland Mars 400 1080P Wireless Dual HDMI Video Transmission System, 400ft iOS & Android App Monitoring with 3 Scene Modes, OLED Display for Vlog, Live Streaming, Multi-Camera Production

When it comes to setup, some of it can be quite expensive or complicated. The Mars 400 stands out from the crowd because its price is much lower, and it works right out of the box (with the exception of one battery and cable, which I'll explain later). There's no need to set anything up unless you want to change the scene or mode it's in. As a result, despite having fewer features than some, it makes some of the other equipment options look pretty bad. br>br>Aside from that, the Mars 400 has a slew of interesting features. It's nice to have dual HDMI outs for one, as well as automatic channel scanning (maximum of eight channels to choose from). The "up to 400 feet" spec, on the other hand, is extremely useful when running around outside (virtually regardless of what you're trying to accomplish). br>br>You can connect up to two receivers to the same transmitter (much like a wireless lav), but you'll have to buy the second one because it only comes with one. You can also choose to use only the one that comes with it, but you'll be able to stream to up to four mobile devices (iOS or Android) in addition to it. br>br>The above-mentioned scenes/modes, of which there are three to choose from, can be used to adjust the latency. It's a toss-up between picture quality and speed (latency), with the middle option balancing the two. There isn't much of a difference in terms of speed. Unless you absolutely need to save every ms of latency time possible, I'd recommend focusing on picture quality over anything else. br>br>As previously stated, it works right out of the box in terms of settings and functionality. However, because it only comes with a single DC cable for external power (typically for the receiving end), you will need a battery. So, as long as the output of the 12V adapter is at least 1,000mA, you can find/use any 12V adapter that fits. Although, since we tried a 500mA 12V adapter and it worked perfectly, it's possible that it's 500mA in reality. It works with Sony F970/550/770 batteries (which you must supply because it does not come with any). If you stick to generics, they won't cost you too much. Otherwise, you'll have to pay a little more for the genuine Sony brand (the F970 battery, for example, costs around $120, while the generic costs around $20-$30). It's $40, and it usually comes with two). It appears to work fairly well in our tests. br>br> We were able to stream it throughout the office with no problems. We streamed it to a TV on the wall in front of the camera (one of the sets here), as you can see in one of the images. The worst we could see was around half a second (if that) in picture quality scene/mode latency. br>br>We preferred the DC cable on both because it can quickly deplete a battery (much like an LED light or an external monitor), but if you're using it outside, you'll probably want to stick with the batteries. Even more reason to stick with generic batteries (assuming they perform as well as Sony-branded batteries). br>br>**If you found our review useful, please vote it up in the poll below to let me know. This will make it easier for me to provide useful feedback in the future.

br>br>I've now had the opportunity to test this system in a variety of situations. I'm a DJ who specializes in karaoke. The ability to wirelessly transmit video to various areas of an event space can be a very useful feature. The first test I conducted with this system was in an open field with the receiver approximately 330 feet away from the transmitter. That far away, the video and audio transmissions were flawless. Even after moving the receiver back to about 375 feet, the video and audio feeds continued to work flawlessly. br>br>I also put this unit to the test in my apartment, sending the signal to a TV on the roof of my building, which you can see in the video attached. Even though the signal traveled through multiple walls in my apartment complex, it took some time and some adjusting of the receiver before I was able to get a clear picture. The receiver and transmitter appear to be primarily made of metal, with adjustable, primarily plastic antennas. br>br>The overall feel of this system is very nice, with the receiver and transmitter appearing to be primarily made of metal. I also like that the receiver has two HDMI outputs rather than just one. One of the few drawbacks to this system package is that it does not include everything you'll need to get it up and running right away. Batteries, HDMI cables, and an HDMI adapter cable for your camera (if you want to use this on your camera) are all items you'll need to purchase. ) Aside from that, this video transmission system appears to work well once you have everything you need. The fact that I was able to use this system from such a long distance was incredible. On top of that, when I tested the receiver for distance, I kept it close to the ground. I wouldn't be surprised if this system could go beyond 400 feet if the receiver was placed higher. Overall, this is an excellent transmission system. I would suggest it.

The plug-and-play, run-and-gun champions are Hollyland HMDI wireless transmission systems. When on a shoot, a good piece of equipment is something you don't have to watch over. When powered up, the transmitter and receiver are both very user-friendly and go to work right away. The flexibility of a DC input allows you to move the weight of a large battery to another location. A monitor can be used to loop power. I've attached a monitor and the Hollyland to any HDMI video output source as a light-weight quick-release attachment. If using an external battery is not possible, adding a battery to the monitor or transmitter works just as well. Being over the age of four Optional camera accessories come and go in the video industry, some are silly, while others make the shoot easier. Any professional videographer's arsenal should include the Hollyland Wireless transmission system. I must add that Hollyland did not skimp on the build quality, which is outstanding. I'm looking forward to my upcoming photo shoots! Fairhaven, MA's West Island Weather Station is represented by MLBaron.
