Hidden screen-camera communication emerges as a key enabler for the next generation videos that allow side information, such as TV commercials, augmented contents, and even the video itself, to be delivered to machines during normal watching. To guarantee imperceptibility to human eyes, existing solutions have to sacrifice data rate and reliability enormously. This paper presents AIRCODE, a hidden screen-camera communication system built upon invisible visual and inaudible audio dual channel. While ensuring great unobtrusiveness, AIRCODE achieves robust communication at a remarkably high rate of 1Mbps, for the first time, enabling imperceptible transmission of not only texts but also videos. AIRCODE makes two key technical contributions. First, AIRCODE takes the complementary advantages of video and audio channels by exploiting the reliable yet low-rate inaudible audio link as the control channel while the unreliable but high-rate visual link as the data channel. Second, AIRCODE incorporates visual odometry to accurately identify and track the captured screen, regardless of dynamic video contents and surrounding interference. Experiments on commercial monitors and smartphones demonstrate that AIRCODE significantly outperforms the state-of-the-art system, yielding a remarkable data rate of 1069 Kbps while with BER of 5%.

Again, I understand that it is doable to use the flip screen tucked in against the body, just that in order to save a bit of time and make one less thing to have to concentrate on, it would be nice if I were able to use the flip-out screen in the flipped out position.

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.

If you want a compact camera that produces great quality photos without the hassle of changing lenses, there are plenty of choices available for every budget. Read on to find out which portable enthusiast compacts are our favorites.

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.

I would certainly like to see this also. Could essentially turn SBP into a full screen sketchpad on a Cintiq Companion.

Though it would be better as an addition to the current full screen implementation which I use a lot.

But the most viewing is from the nest hub in our bedroom at night, which for obvious reasons, we leave streaming until the morning. We did this for around 7 months with no issues. However, over the past few weeks we have woken with the nest hub screen black. The camera is working fine, as I can quickly view the feed on my phone.

We worry we may miss our son crying, if the device was to "black screen" whilst we are asleep, fortunately this hasn't happened yet. But would like to remove any potential for it to do so in the future.

The screen will be out of focus, like the above poster said, straight on is best, not an angle. To add to that, if you have to put it behind the screen, try and get it as close to the screen as you can. I know you said only for day, but if you happen to use it at night, the IR bounce back would I think be pretty narly if used.

I have a couple V2 cameras sitting in a bay window. The cameras shoot through double pane glass and outside of the glass was a screen. It was horrible. I moved the cameras to the upper part of the window that does not have a screen. Much better. Of course I have to leave the IR light off.

Measure and mark the vertical distance from the ground to the center of the camera lens. The assumptions in these measurements are that the vertical and horizontal dimensions are in the same units and that the horizontal and vertical are reasonably level and plumb.

I am not so sure that the camera must be aimed directly at the screen. Even when the camera is aimed directly at the screen, only the light rays emanating from the center of the field of view are square to the screen. All other light rays are passing through the screen at ever increasing oblique angles.

My V2 Wyze cam has been mounted in my sun porch behind sliding glass door and screen door for about 2 years. The picture I get is fine. I have the IR turned off with outdoor lighting on at night and picks up fine behind glass and/or screen door.

I have a dslr camera which does not have a flip screen. So in situations where i want to take a shot from very low angle, It is very hard, compared to the flip screen available situation. Is there any tips or tools which helps me to handle this situation ? May be i can connect my camera to my phone and use the phone as the screen with the help of some app ?

The flip screen, usually called rotating screen is a liability. Even tilting screens are more fragile than a fixed one, so your camera is tougher for the matter. This constraints flexibility of composition but it is usually easier to keep things level when using the viewfinder, even if you have to crouch. There are a few things you can do to help with that:

They just clip onto the viewfinder where the little rubber eyepiece goes. Generally they rotate left and right a bit to give you a bit of flexibility in how you position yourself, and you get to physically see through the lens which can be better than using the live view image on a screen.

Not every camera that has been used effectively in the past had a way of seeing the exact scene immediately prior to taking the image. Many historically and artistically significant images were made without a real time view of the camera's field of view. Even focusing was a guessing game assisted by aperture and distance scales on lenses.

The next time you watch the end of a major sporting event or the circus outside a courtroom as a high profile personality is going to or from the trial look at all of the news pros (stills and video) in the shoulder to shoulder crowd shooting blind with their cameras held high over their heads. Very few of the still cameras have movable screens because not only are the screens themselves more fragile but they also make it more difficult to seal the camera body from weather and other harsh environments.

In "pre-digital" days you only had 24/36 frames until your "buffer" was full for a 35mm SLR. You had even less if you were shooting 120 format roll film in a Speed Graphic. Nobody shot 1000 images of anything. Sure you may take a couple of extra safety shots, but you had to learn how to point the camera without having your eye glued to the viewfinder.

There were, however, motor winders that attached to the bottom of the camera that allowed shooting at a blazing 2 fps! And you could get a film back that could hold a roll about 100 shots long. But those things were way too heavy and bulky to use free hand over the head.

Here's a friend of mine shooting the football game for a local newspaper. (He's had hard news images published in the NY Times. He's had a photo essay shot entirely on a smartphone about small town youth league baseball published in ESPN the Magazine.) When the play started the line of scrimmage was 30-40 yards up the field from his shooting position so he was shooting with a long lens. As the play developed and a pass was launched to the side of the end zone right in front of his position he put down his long body and began raising his wide angle body just in time to catch several frames as three players and the ball arrived simultaneously. The shot he grabbed a split second after the time I captured the image below was published as the lead image on the sports page in the next morning's print edition that went to press barely an hour after this happened. (Yeah that's me way in the background.) He still didn't have the camera up to eye level in my frame taken after the shot published at the link above. In the online photo gallery for the newspaper's coverage of the game he published a total of four images (#'s 1, 2, 11, and 12) captured between the time the football was knocked away (as shown from a different angle by my first image above) and when the ball hit the turf barely one second later (my first image is timestamped 20:04:39, my last image is timestamped 20:04:40).

Some cameras had no way to see through the lens prior to taking the shot. A cursory viewfinder was attached to the side of the camera or, if you had a deluxe model, to the front standard that held the lens. No accommodation was made with such viewfinders for lenses of varying focal length. The photographer just had to know how wide the angle of view for the lens being used was. Focus was set by estimating or measuring the subject distance and lining up a mark on the lens to a scale with that distance. Aperture and shutter speed were also set manually with no metering built into the camera. Some of those cameras used roll film with anywhere from 6-12 shots per roll. Others used sheet film that had to be changed after every exposure. The latest versions of such press cameras were still being used by local press photographers in my hometown as late as the early 1970s.

Reviews on the Android store suggest mixed results, but I successfully used it both from Android devices and my Windows laptop. WiFi connection was provided by a TP-Link MR3040 router with a custom Firmware that can be downloaded from the DslrDashboard website, plugged into the camera USB port. 006ab0faaa
