TEST: Eachine EV800D (5″, 800×480, diversity, DVR)

null

INTRODUCTION

After the Eachine VR-D2 pro, here is the new revision of one popular goggles model from Eachine, the Eachine EV800D. If for the VR-D2 the changes between the two editions are more concerning the LCD and DVR firmwares, with the EV800D we have major hardware changes versus the EV800. Now diversity and a builtin DVR are integrated. Paradoxally the EV800D becomes a direct competitors for the VR-D2 Pro…. Let’check this new offer.

BOX CONTENT

null

+ 1 x Eachine EV800D
+ 1 x Charger
+ 1 x 5.8G halfplanner antenna with SMA connector
+ 1 x 5.8G RHCP cloverleaf antenna with SMA connector
+ 1 x AVin cable
+ 1 x DCpower cabler to 3S balancer plug cable
+ 1 x Fresnel lens clearning kit
+ 1 x Instruction manual (English)

A circular and a half plannar antenneas are provided with semi-rigid stems. Good news, the ciruclar model is 6 leaves based offering a +5dBi versus a +3dBi for a classic cloverleaf.

null

OVERVIEW

The main chassis/mask is the same versus the original model build with a beautifull mate and soft plastic. The EV800D can still be splitted in two parts to be transformed into a 5″ FPV monitor.

null

Still no possibility to tune the Fresnel lens distance but good news, they upgraded the Fresnel lens with now a better/larger magnifying factor.

null

The general caracteristic of the LCD screen remains the same, i.e. a 800×480 5″ model with a 600cd/m2 as brightness. 800×480 is not perfect to display a PAL source (756×578).

null

null

From left to right we have: a 5.8G autoscanning button/increase value, a power indication status, a microSD card slot (only class 10 are accepted if not you will have corrupted files written), the src/menu botton, the power on/off (2s press/5s press), the CH+/band+/decrease value and picture(short press)/video (press 2s) button.

null

If shortly pressed, the SRC button will cycle between diversity RFmode, RF antenna B, RF antenna A and the AVin. Is you long press on it (more than 2s), you will enter into the LCD menu where you will be able to set a lot of settings. In the LCD menu, press one more time this button to navigate between each settings. To increase a value press the scanning button, the decrease press CH+/band+. Press the power button to exit from any menu.

null

null

Good news, the right earphone plug can be used also to input an AV source. You even have a dedicaced cable for that job.

null

Another good news, in the bundle you have another power cable ending with a 3S balancer plug. It means, you can recharge in the field thanks to a 3S LiPo the builtin battery.

null

You can install the FPV monitor section on a tripod vie the M6 screw.

null

The headstrap is a three point models where you can tune the lengh for each of them.

null

The same facial sponge is installed, confortable but you will probably sweat with in warm weather conditions.

null

If the noze section is super large, even too much since some light can be noticed via this gap,

null

the general opening could be a little bit more important to be compatible with most of glasses.

null

null

Weight

null

405g in total, one of the most light model in the market.

null

Display

The display presents immediatly the white snow synonym of LCD firmware FPV friendly. No problem of blue/black screen when the FPV signal is lost. The brightness is really good, one of the best for such kind of FPV goggles. The color rendition also pretty good.

null

A lot of settings can tuned… especially you can change the aspect ratio between 16:9 and 4:3 and rotate/flip the video source. Very usefull sometimes when the FPV camera must be placed upside down.

null

Basic but important OSD informations are displayed in the top left corder, i.e. the type of RF sources (diversity, RF B, RF A) or AVin. If a FR source is selected, you will have also displayed the a couple letter-number respectively for the selected Vband and Vfreq and the exact frequency correspondingly.

null

The battery capacity is displayed on the top right corner. When one bar is remaining, the status is displayed in red. No builtin buzzer to ring an alert.

null

DVR

Good news, the DVR detects automatically the type of input video source.

When it’s an NTSC, files are recording in 720×480@30fps without any cropping:

null

null

When it’s PAL source, files are recording in 720×576@30fps. The most surprizing is the 30fps … In theory PAL should also offer only 25fps.

null

The DVR probably oversample to reach 30fps. For PAL, the bottom part is cropped just a little for few lines… (10 maximum), really nothing castrophic.

null

The good news, for a NTSC or PAL source, recordings are perfectly synchronized when an HD camera. It’s great for picture in picture video editing for example. The DVR playback section presents a chinese message …. No english tranlation available. Probably a firmware update will solve this minor problem.

null

UNBOXING, ANALYSIS AND TESTING

In practice, when you start a recording (press more than 2s the corresponding button), a small red circle point appears. This point dissipears after 15s. Short press the same button to stop recording and a red square will appear. When a photo is taken you during 1s a green square appearing. I really like the LCD display with faithfull colors. The brightness is really good too.

CONCLUSIONS

With a good RX sensitivity, better than with the original EV800 version, good 5″ LCD screen and with a good brightness and color rendition and with a fully working DVR without any latency, frame rate drop when recording is turned on…. the EV800D can be considered as main probably the best 5″ Eachine goggles. No real drawback can be found except the non possibility to tune the fresnel lens distance and the difficulity to install easily some correction glasses. I recommend the EV800D over all other 5″ Eachine models.

PROS

+ Good 5″ LCD screen
+ Good RX sensitivity (-95dBm)
+ Diversity
+ 6 leaves RHCP antenna (+5dBi vs +3dBi)
+ Can be transformed into FPV monitor
+ Good DVR working fine for both NTSC & PAL sources (detecting automatically the type of source)
+ No extra latency/frame rate drop when recording
+ Recording OSD information
+ Aspect ratio (16:9/4:3) and rotation settings.
+ Builtin battery (~1.5h of usage)

CONS

– No lens distance ajustement
– Light introduction via the noze section
– Not compatible with all correction glasses
– Chinese language for the DVR playback section

    Hello Seby,

    On the VR D2, I have to set the fresnel lens the closest as possible from my eyes to get the more accurate picture (and also the biggest since it’s closer). As many users reported, even at this close distance, the picture is still a bit blurry, and many users have inserted a second fresnel lens to have a better view.
    Can you tell me if on this new FPV goggles, with a static position of the fresnel lens, how does it compare with the VR D2 ? Closest position , medium, or the most far which makes the picture small ?

    Thank you

  • Jancis says:

    What’s the range with 200mW and maybe some smaller TX’s in meters? I am considering these to replace 007’s.

    • SeByDocKy says:

      It’s not really possible to give an information of distance coz it dΓ©pends also of type of antenneas, polarization, location… and some other factors. But I can say we have a -90dBm for the VR007 versus -95dBm for the EV800D… more the antenneas offer a +2dBi (dBi <> dBm) versus a classic cloverleaf. So I will say in openfield condtions you can expect to double the FPV range with the EV800D.

    • Krotow says:

      Depends from antenna type and configuration of obstacles in your flying spot. From personal experience in open field with 200 mW VTX and 5 dBi cloverleaf RHCP antenna it was no problem to receive clear picture without noise in 500m range. Didn’t tried farther so far because didn’t wanted to fell into living houses beyond mentioned distance. Stick antenna from TX03 AIO cam in 200m range worked as well too. 25 mW VTX is visible in around 100-120m range. Wet trees and bushes in middle between VTX and you may cut receiving range to half or more so always pay attention to VTX RSSI indicator – small green antenna level picture at top left side. It display FPV receiving status quite precise.

    I bought one after viewing your review πŸ˜‰

  • Anonymous says:

    Nice article! But the connector type is SMA here, not RP-SMA. Thanks.

  • Geo says:

    Do you prefer these or eachine Goggles two? Image quality, signal perception comfort. Which one is better?

    • SeByDocKy says:

      In term of image quality and HDMI connexion, the goggles two us better but a wide screen can be very tiring for eye too. In this way, the EV800D is better. Another point, the Eachin goggles 3 with a builtin DVR will be probably introduced very soon too.

      • Geo says:

        thanks. in terms of comfort and signal perception?? if you had to choose between those, which one would you buy?? maybe goggles three will be better of all but would cost around 140 euros too..

        • SeByDocKy says:

          Yes I think the Goggles 3 will be around 140-150$ …. Hard to choose between both. Is HDMI, inpoutting HD sources important for you ?

  • Ben says:

    Does anyone know if I can I use a 2s battery for back up? Or just 3s

    • Krotow says:

      You definitely can use 2S battery as backup or even two 1S batteries connected in serial connection πŸ™‚ However you must have adapter from 2S balance male connector to 3S balance male connector. Or from two 1S to 3S (1S side depends from connectors on batteries which you have). For mine EV800D I soldered 2S to 3S adapter and 1S+1S (red JST and white WST) to 3S adapters by myself. Works like charm.
