Both the mounts are the same height. Could it be a spare mount?

H.265 Medium bit rate
Front cam: 2560×1440 30fps – Overall bit rate: 23.7 Mb/s. 170MB per 1min file.
Interior cam: 1920×1080 30fps – Overall bit rate: 10.3 Mb/s. 73.8MB per 1min file.
Rear cam: 1920×1080 30fps – Overall bit rate: 10.3 Mb/s. 73.9MB per 1min file.

H.265 High bitrate
Front cam: 2560×1440 30fps – Overall bit rate: 27.8 Mb/s. 199MB per 1min file.
Interior cam: 1920×1080 30fps – Overall bit rate: 14.6 Mb/s. 104MB per 1min file.

Rear cam: 1920×1080 30fps – Overall bit rate: 14.6 Mb/s. 1049MB per 1min file.

The H.265 encoding is a hidden mode in the T3. To enable it, stop recording and hold the mic button on the T3. An SD card icon will appear on the left side of the screen to indicate using H.265.

Using H.265 will save some space on your micro SD card but do take note that currently not all devices are able to play H.265 properly as it requires more processing power to decode during playback.



Parking mode

There are 2 parking modes available – Timelapse 1fps & Low Bitrate recording. Zenfox hardwire kit is required to use the parking mode.

The Zenfox app is very easy to use. Streaming using Zenfox app is very quick and no noticeable lag was encountered.

The Zenfox app can configure most of the settings of the T3 except the Infrared settings which can be configured physically on the T3.


Test setup

I will be using a 128GB Netac Pro microSDXC V30 card for the recordings.

Interior cam has 3 modes for the infrared – On, Off & Auto.


Final thoughts
The T3 3H is a must-have for those driving ride-sharing as it covers the front, rear, and interior of the vehicle.

The Zenfox app is very easy to use and can stream the videos without any noticeable lag via the 2.4GHz or 5GHz.

If you have the top black tint on your front windscreen like me, you won’t be able to stick the T3 higher up on the windscreen as the black tint will block some of the front cam’s angle.

Hi,

I have a couple questions.

1. Is the Rear Camera mounted on your windshield via the 3m adhesive or to a suction cup? It appears the rear camera isn't sitting flush against the glass in your videos?

2. Is the Front Camera flush against the glass via 3M mount or a suction cup?

Night time video seems a bit washed out on front + rear but it could be your choice of mounting? Or are your windows heavily tinted?

Front and rear using tape mount. The rear cam got the shade I'm using there is pushing the cam a bit and it's not at the center. More to the right side of the car.

Front cam is also more towards the right side of the car due to the top black tint.

My car is tinted with LLumar Diamond 6.

I have 80% tint on my front an 20% on rear. So will be interesting to see how well it can see at night. My camera got delayed. Should have tomorrow or Wednesday.

I enable WDR on my Viofo just to see out the back window "somewhat" at night. Tint definitely adds challenges to a camera's ability to capture images clearly due to the lesser amount of light.
