GoPro challenger: HoryzonHD 
(pre-production, mini review)

By: David Windestål

This is the new HoryzonHD FPV camera from The unit I’ve got is a pre-production unit equipped with a wide angle lens, but I should receive the stock finished product any day now and when it does I can test the camera out for real. But in the meantime here is a mini review/comparison to the GoPro.

I’ve wanted a camera like this for ages. I even tried to modify my own cameras to add a long ribbon cable but it failed. So I gave up on the idea and got a GoPro when it was released instead. But now my dream of getting HD video from a tiny, light weight sensor can finally be realized. Finally a real challenger to the GoPro for HD FPV flying has arrived!

The down sides of the GoPro HD camera is that it is not very aerodynamic. It is also relatively heavy. These two things makes it less than ideal to pan and tilt on a FPV platform. The HorizonHD on the other hand has a tiny, light weight sensor that is both aerodynamic and easy to pan and tilt using quite small servos. This is its real strength, but it also has some other nice features that the GoPro lacks. For one thing, it has a built in display, which is really nice and comes in handy when setting things up. The HorizonHD can also be powered via the 5V of a spare channel of the receiver, no separate power-source is needed. The HorizonHD also has the advantage of weighing only 40% of the naked GoPro. Weighing in at only 40 grams (with an LCD display and all) – at least I’m really impressed by that. But how does the video quality compare to the GoPro? Let’s find that out, shall we?

Weight: ~40g
Length of the cable between the main unit and camera head: ~20cm
Memory cards supported: MicroSD
Field of view: 120° (140° with optional wide angle lens)
Recording format: H264 .MOV
Average bitrate in 1080p and 720p60FPS: ~15mbit/s
LCD display resolution: 960*420
Supply voltage: Up to 5V (Plug straight into receiver or use a 1s LiPo)

The main unit is covered in a clear heat shrink. This pre-production unit had some scratches in the heat shrink the finished unit should be nicer. The relatively big LCD screen takes up the whole front of the camera.

The back side of the main unit. Here you find the control buttons. They are quite hard to push and quite awkwardly placed as the LCD screen is on the other side. To me it would have made more sense to have them on the same side as the LCD.

The side of the main unit. A mini HDMI and mini USB connector which is also used as the SD video out. This side also has the power button which for me (with my manly fingers, without nails) is really hard to push. I use a screw-driver to push it (see picture). I wish that it had been mounted in a more easily accessible place, or just further out.

The screen is really nice. It displays the information needed and makes setting things up a lot easier.

The sensor unit. Really, really small. I’s more or less just the sensor and a lens.

The back side of the sensor unit. I’ll add some glue to make sure that the cable wont come loose during flight, just to be on the safe side.

Size comparison to the GoPro. Smaller, lighter and with a cable that lets you place the lens away from the bulky parts – great.

Time to test the HoryzonHD against the GoPro Hero HD!

As you can see in the video, the HoryzonHD camera in not quite as sharp in the edges as the GoPro (it might be better with the stock lens though). The raw video from the HorizonHD does not look quite as appealing as the GoPro. This has a lot to do with the fact that the GoPro camera automatically increases the contrast as well as a few other parameters directly in the camera. The HorizonHD has a bit more information in the video, which is nice when editing, but isn’t as nice when you don’t want to mess around with levels and such. To each what each prefers - this is a plus in my book, but it’s really a matter of preference.

The average bitrate of the GoPro during these recordings was 15123 kbit/s
The average bitrate of the HorizonHD was 15128 kbit/s
Which is to say that they are more or less identical - no winner here.

(For those of you that really want to study the differences, you can download the original video file here: Download the original .MOV file)

I’m quite impressed with the quality. It would have been nice with even higher quality, but that is true for all cameras. The quality is pretty much equivalent to that of the GoPro, so no clear winner regarding video quality either. Considering the size and weight of the HorizonHD camera though, the quality is really quite impressive and the price of 150USD makes it even more so.

I can’t wait to get the real retail version of this camera and really compare it to the GoPro. From this initial testing it seems that the GoPro might have a real rival for the first time.

Both look good, The gopro looks better because of the way it adjusts the colors automatically in camera, but the horyzon colors looked comparable to the gopro after post processing. Since the horyzon cam weighs much less than the gopro, and will have less aerodynamic effect on the model plus a display this should make this camera a serious competitor. (if you don't mind doing some color correction) I own a gopro and a gopro 2, and I am very interested in this product, can't wait to see the results from the production version..

the colours on the Go Pro HD is much more vibrant than the Horyzon one, which to me makes me want to go for that one over the horyzon camera.

Hi David! Thank you for posting such a good review. I love your site and how you put so much detail in explaining things.

I'm going to order one of these cameras when they become available. I think for the RC enthusiast this little beauty at $150 is perfect!

Thanks again for your post!

Shouldn't the comparison be with the new Go Pro Hero 2? Have been very impressed with the colors, low light, picture quality and over all performance of the Hero 2. It sets the bar, so to speak. Any other camera needs to compete with it, not the early version of the Go Pro.

Good comparison! the horyzon HD would be better for FPV because you fly outside in high to medium light, and you need the camera to be as compact and light as possible. but the go pro is better quality all round, but is a little on the heavy and bulky side, but you just can't beet a go pro
