In Februrary INNOVV kindly sent me an K3 for testing and reviewing. And of course I would like to give you all a short review of the K3, combined with a comparison to the K2.
The DVR of the K3 is made of aluminium with a plastic top cover and it is a little bit smaller than the DVR of the K2. The SD Card slot and USB Port are protected by a simple rubber lid, which allows an easy access to both. The cameras, the remote control and the microphone are also made of aluminium and look very sturdy and valuable. All components get connected to the K3 by sealed metal GX9 connectors, which are all color-coded for easy installation. You really don't even need to look at the well-made manual to know where to connect which component. And the fact that all connections are led out of the housing of the DVR makes it easier find a suitable place for the DVR at the bike. The small connectors also makes it easier to edge the cables through holes during installation.
I like the new K3 DVR with its external connectors more than the one of the K2, as it is easier to install. Especially the camera plugs at the K2 takes a lot of space at the side of the DVR.
With the K3, they are much easier to handle.
The mounting accessories consist of plenty of clamps, screws, plates and self-adhesive pads to mount all parts anywhere on your bike. The clamps for the cameras allows to adjust the rotation, direction and tilt level of the camera. So there are literally no restrictions where to mount them on your bike. And the manual clearly explains how to install everything.
While both the K2 and K3 are some kind of "install-and-forget" dashcams, the K3 gives you more feedback and control with its new remote control. You can clearly see if the K3 is powered on, if it is recording and what the status of the GPS is. One click at the remote control protects the current videos (front and rear), a double-click takes a photo on both cams. This works pretty well, even with gloves, as the button gives you a good feedback. The "protect video" function can be essential in coutries where permanent recording is not allowed.
Regarding WiFi, the K3 shows only slightly improvements compared to the K2. Both supports only 2.4GHz, but the transfer speed of the K3 has been increased a little bit to around 3.5MB/sec. That's fast enough for streaming and downloading short clips, but not enough to download a whole trip. Especially as there is no power button anymore, with which you could manually power up the K3 to download videos, like at the K2. But for downloading a whole trip, I guess everyone will simply take out the SD card.
Video quality and sound
The first big improvement for the video quality of the K3 is, that it allows you to adjust the bitrate for video encoding in four steps from low (12 MBit at 1080p / 6 MBit at 720p) up to Maximum (20 MBit at 1080p / 10 MBit at 720p). At the K2, the bitrate is fixed at 12 MBit and you need to install a modified firmware to increase it.
The sharpness of the K3 videos is exactly on point. Sharp enough to record necessary details like number plates, but not too high to get noisy. As the new cameras of the K3 suports a wider dynamic range, the brightness is very good in low and normal light conditions. This is especially at night a real plus.
Only at direct sunlight the videos look a little bit too bright in my eyes. The saturation also seems to be a little bit too high. On some occasion and light conditions, the video got red-tinged, sometimes blue-tinged. But as I already reported this to INNOVV, I am sure they will fix it in future firmware releases. So compared to the K2, the videos of the K3 show much more details.
The K3 cameras also seem to be less prone to vibrations. Though the cameras were mounted at a position where the K2 showed a lot of jello effects, I only got minor jello effects on some occasions when riding at higher rpm. That's another plus.
The K3 features an external microphone with a deadcat, which can be placed anywhere on your bike. For my test rides, I mounted the K3 only temporarily and simply placed the microphone right under the seat. So I can not say much about what could be possible. The sound is better than at the K2, but there still seems to be some kind of gain control, which sometimes reduces the sound to nearly zero. May be that a different position, where the sound is not that deep, would bring a better sound. As soon as the K3 is mounted permanently, I will try to find a better position and alter the gain level by firmware modification ;-)
I made three comparison videos for the K3 and K2, which you can download here.
When comparing to the K2, I have to note that I used my modified firmware on the K2 with a bitrate of 20MBit (default is 12MBit). So it is more a comparison of „how videos of the K2 could look like“ vs „how videos of the K3 does look like“. I decided to do the comparison this way to really only compare the different cameras, eleminating the different compression bitrates.
I really like the K3. It is the consistent further development of the K2 by taking it advantages, but not their disadvantages. Mounting is easier, due to its smaller size and the small GX9 connectors. The cameras of the K3 can be installed as stealthy as of the K2, but their video quality is much better, especially at low light conditions. You can adjust the video bitrate within the app and the remote control always gives you feedback and control of the K3.
If anyone has any questions regarding this review or the K3, just ask.
