I am aware that the timestamp of the SensorEvent is the nanoseconds since the operating system started (uptime).On the other hand the getTimestamp of the Image (that comes from the ImageReader) is measured in nanoseconds but the timebase depends on the source providing the images (Camera, CameraDevice, etc). In my case I am using the CameraDevice (camera2) but I haven't found what is the timebase of the CameraDevice.
UNKNOWN: "Timestamps from android.sensor.timestamp are in nanoseconds and monotonic, but can not be compared to timestamps from other subsystems (e.g. accelerometer, gyro etc.), or other instances of the same or different camera devices in the same system. Timestamps between streams and results for a single camera instance are comparable, and the timestamps for all buffers and the result metadata generated by a single capture are identical."
But the timestamping is often not very accurate (meanining, off by several milliseconds), which is why these devices report UNKNOWN, since the timestamp accuracy is not high enough to reliably correlate to other sensors' timestamps.
No, you will also connect the hotshoe adapter to the time mark input on Reach. Timestamps will be in the raw data logs, you process the logs with RTKLIB and get a list of coordinates for the timestamps.
These two models of Sony cameras have been used successfully at 12 to 14 m/s, Sony A6000 and Sony QX1 using this trigger cable trigger cable, both cameras using the Sony 16mm fixed focal lens for 2cm GSD and higher at 100m, triggering at 1 sec intervals. The Sony A6000 has a hot shoe, and the hot shoe adapter from Tuffwing or make your own, will capture the shutter activations, and long the activations to the Reach unit.
Timestamp camera: Auto Date Time Stamper App is a free multimedia application developed by Susamp Apps for Android devices. This app allows you to add date and time stamps to your photos easily. You can also add custom stamps like signature, location, logo, sequence, tag, altitude, and speed to your photos.
With Timestamp camera, you can protect your photos by adding watermarks and captions. You can select the format, size, style, position, and color of the stamps. The app also offers a unique feature where you can add a logo image wherever you want on the screen.
Additionally, Timestamp camera has a geotagging feature that allows you to add GPS geolocation (current or custom stamps) to your pictures. You can turn on location on your Android cell phone, and this app will become a GPS map camera for you.
Overall, Timestamp camera: Auto Date Time Stamper App is a user-friendly app that offers a variety of options to customize your photos. It is perfect for those who want to keep track of their life's important events with exact dates and times.
It's not possible to do what you're asking with 100% certainty. Pretty much everything we're going to be able to come up with can be spoofed or tampered with. I don't have details on this specific case, but it may be possible that you're just over thinking it. First, will the accused even be smart enough to challenge your evidence with a plausible scenario as to how it would have been tampered with? Probably not. Second, will the court even care if they did? I think in most cases, the standard for evidence is much lower than what you're expecting. Simply keeping detailed records with video and a simple on screen timestamp may be enough.
As several people above referenced, the threshold for good evidence is not as high as you think. Andrew2836's advice to farm out the set up is an excellent one. While plenty of TV and movie plots use tampered photo/video evidence as a focal point, it really is rare. My BS is in criminal justice so I have a very good level of knowledge in regards to evidence, procedure, etc. Another thing that would help bolster your evidence is to enclose the system. Make it so access was view/read only. Very good, very legitimate convictions can be made on evidence far less verifiable than video. A simpler way is, again, as referenced by Andrew 2836. My only additional piece of advice would be find out what, if any, videotaping laws may apply in your area. Depending on what you are taping and where the camera and the area viewed are located, you might have to post that cameras are active, or have permission from the owner of the physical sites themselves (not sure about your details). These things are far more likely to create issues than a legal challenge of the veracity of a time/date stamp. Good hunting :)

Timestamp Camera is an interesting application that enhances the realism of smartphone cameras. It has user-friendly but comes with flexible AI customization to bring users many impressive improvements. This application provides additional information such as location, and shooting time, and maps into the image in a detailed and neat way in the form of text printed on the photo or video like the way digital cameras often do. In short, the application helps users to have good quality photos but also helps to display important information about the geographical location and time of each photo or video.
The enhancements allow users to produce the most immersive and vibrant photographs possible. Besides, the artificial intelligence will automatically modify the perfect colors and brightness based on a pre-setting, which will provide them with more creative ideas for producing artistic content. We are lucky that the upgrade system for the camera allows for a great deal of customization so that every user can change or modify their photography.
However, your camera will record the time and date the image is taken in a data section of the image file. Many photo-editing programs can read that date and time information and place it as text in the displayed image. The exact procedure for doing this depends on the individual piece of software, so you will have to read the manual or help file for the software you have.
The LowePro PhotoSport Outdoor is a camera pack for photographers who also need a well-designed daypack for hiking and other outdoor use. If that sounds like you, the PhotoSport Outdoor may be a great choice, but as with any hybrid product, there are a few tradeoffs.

What's the best camera for travel? Good travel cameras should be small, versatile, and offer good image quality. In this buying guide we've rounded-up several great cameras for travel and recommended the best.
Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.
On newer Motorola phones like the Moto G series, there is an option in the camera settings to add a timestamp over the photo when taken. It is often the easiest option if your smartphone has the timestamp feature.
Android does not usually have the option to superimpose a timestamp on your taken photos, but some phones offer it. As previously mentioned, Motorola G series phones (and probably other models) let you add a timestamp, and some people report that select Samsung phones do, too. To see if your phone has a photo stamp option, do the following:
Automatic time stamping is essential to many Android users. Fortunately, there is a wide selection of free apps for this purpose. For those lucky enough to have the option built into their phone (rare), like with specific Motorola or Samsung phones, you do not need to add more apps and consume more space. Of course, you may want additional features that a third-party camera app provides.
This happens to me as well. Why is this camera so expensive but missing the most simplest function of have the video time stamped??? isn't that the point of a security camera, to capture an event and show when this event happened?
AGREED! And how about adding the ability to download a custom clip of you're choosing! PLUS, you can only do it from your PHONE, not a computer! I just bought a Gen 2 camera and a doorbell only to find I can't get the timestamp showing on downloaded clips unless I use special software! It's the most frustrating thing and I think I'm going to return them and switch to Ring.com. I NEED A CLIP FOR LEGAL REASONS AND I CAN'T GET IT SHOWING THE TIMESTAMP!!!! DO YOU THINK A JUDGE WILL SIT DOWN AND FIGURE OUT HOW TO TURN ON SUBTITLES TO GET THE HIDDEN TIMESTAMP!! ITS RIDICULOUS!
