This is the new HoryzonHD FPV camera from Foxtechfpv.com. 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?
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!
