HOLLYLAND MARS 4K REVIEW

HOLLYLAND MARS 4K REVIEW

Are you filming with a drone, camera arms on your car, or just want to watch the camera feed remotely without the need for cables? Then the HollyLand Mars 4K is for you.

Today we're taking a look at a new wireless transmitter from HollyLand called Mars 4K.

This range has a long history, but what's different? You've probably noticed that we have a design that takes another step forward, but still feels similar to its predecessors.

The receiver and transmitter have an almost identical design, but the transmitter has a red 4K emblem on it and the receiver has a blue 4K emblem on it. Let's take a look at what's in the box! After unpacking, the first thing we see is of course the manual; then the receiver and transmitter, the Cold Shoe, i.e. the sled, the spare antenna and the USB A to USB C adapter. We also have a power adapter with a reduction to a European socket.

TheHollyLand Mars 4K has a very solid construction with an all-metal shell and typical HollyLand style design. The Mars 4K has new antennas that other Hollyland devices don't have yet. Compared to previous antennas, they are shorter and stronger. The transmitter has an HDMI input, an SDI input and a cable power input on it. On the receiver we have one HDMI output, an SDI output and also an input for power over cable. We only get one charger in the box, and it's for the receiver, since you're supposed to keep the transmitter on batteries. Fortunately, the Mars 4K can also be powered by NP-F or USB-C batteries. On the other side, we have a color LCD display for easy parameter settings, a button to move around the display, an on/off button, and a USB-C charging port. Mars 4K has three modes namely: balance mode, speed mode and HD mode. At first, when you see the display, it looks like black and white, but when you press the button to control the display, you go to the color menu with the fact that the display is in high resolution and therefore, it doesn't matter that it is a little smaller than the Mars 400s, which is the previous model. From the bottom we have a thread to screw on a cold shoe, a sled that comes in the package, which can also be attached to the front with another accessory so you can mount the transmitter horizontally.

Using the Mars 4K is really easy. Just connect both devices to power either via battery or charger, and then connect either an HDMI or SDI cable to both the receiver and transmitter. Then turn both devices on. The receiver and transmitter should automatically pair. The time to turn on, pair and begin video transmission is around 35 seconds.

The HollyLand Mars 4K has a smart channel search function, so it will automatically help you select the channel that is most appropriate. Of course, channel selection can also be manually up to you, and what's great about these products is that when you change the channel on one device, the other will adjust itself within seconds. HollyLand lists a maximum transmission distance of 150 meters, which is 30 meters more than the previous model. However, this distance can vary indoors with obstacles or walls. The Mars 4K is compatible with the HollyView app as well as the new Mars M1 monitor. This app is very simple, clear and you can use it as a monitor.

This device can also connect to one hardware receiver and up to two smart devices simultaneously. Or it also goes to four smart devices at the same time. The HollyLand Mars 4K has an ultra low latency of 60 milliseconds. The SDI input has different video resolutions ranging from 720p to 4K and the frame rate here can be up to 60 frames per second. For 4K we can reach up to 30 frames per second. It's no wonder they are called Mars 4K because this is the first video transmitter from HollyLand that can handle 4K. HDMI is capable of transmitting at 4K and 25 or 30 frames per second. SDI only in fullhd, but taken at 50 or 60 frames per second. There's an exception though, and that is that if you have an HDMI input with 4K and an SDI output on the receiver, you'll unfortunately get 1080p out of it, because you simply and easily won't get 4K out of this device via an SDI cable.

For us, the HollyLand Mars 4K is a great video transmitter that is suitable for small production and offers some great improvements over earlier lines. The biggest improvement is definitely 4K, which is not yet present in the other lines and in this day and age where almost everything is in 4K this is already a necessity for all similar products. I'm sure you're wondering about the price too.
