U-838 HD Video Camera User Manual

The inexpensive HD video camera that works great on model rockets!

Operation Guide

1. Charging the Battery

A) The battery in the U-838 HD video camera is a built-in lithium rechargeable battery. You should recharge it before using the camera. The method for charging is: Connect the U-838 HD video camera to your computer using the USB plug on the end of the unit.

B) During the charge cycle the indicator light will illuminate with a red light. When it is fully charged, the light will turn to blue and remain steadily illuminated.

Notice: When battery power is too low, the camera will enter into protection mode. In this state, it can-not be turned on. It should be recharged for video operations.

2. Turning ON the U-838 HD video camera

Press and hold the “ON/OFF” button for 3 seconds. The indicator light will illuminate steadily for about two seconds, then flash once, and return to a steady light. It has now entered its stand-by mode. While in stand-by mode, the indicator LED will be a steady blue light.

If the indicator continues to flash and then turns off the Micro SD card is not being detected or has not been inserted properly. Pull the Micro SD card out completely, and reinsert it fully.

3. Turning OFF the U-838 HD video camera:

Stopping recording video will put the U-838 HD video camera into standby mode.Then press and HOLD the “ON/OFF” button for a minimum of two seconds. The indicator LED on the U-838 will quickly blink 5 times and then the light will become steady as you hold the button. As soon as you release the button, the U-838 HD video camera will be off.

The video is automatically saved to memory during shut down.

4. Recording Video

While the U-838 is in stand-by mode (indicated by a steady blue LED light), press the video stop/start button. The LED will blink two times, and go out. The U-838 HD video camera is now recording video.

There is NO light to indicate that it is taking video. Why is that? Because this was originally intended as a spy camera. A light would give away that you were taking video. We’re not the manufacturer, so Apogee has no control over the lights on the camera.

The lens is not designed for close-up videos. You’ll need at least 50cm (about 20in) between the lens and the subject for proper focus and to allow sufficient illumination.

We’ve been told that the U-838 writes a file to memory every 5 minutes while it is recording. If by chance you leave the camera on by accident or take a long time to retrieve your rocket it will continue to record 5 minute videos till the memory card fills up and then it will start over-writing the cool video you just took.

Video files created are named “PICTxxxx.AVI” (where ‘xxxx’ is an incrementing sequential integer value, beginning at 0001, and sequentially inclusive of other file types previously recorded). They have a resolution of 1920 x 1080 pixels, a frame rate of approximately 30 fps, and contained a single channel of (mono) audio.

5. Pausing Video Recording

Press the start/stop button to pause recording. Any video you paused is saved as a separate video file in the memory.

When in pause mode, the indicator light will illuminate a solid-steady blue color.

To resume recording, press the Start/Stop button.

6. To Take Still Photos

While the camera is on (in stand-by mode, as indicated by a solid/steady blue LED light), momentarily press the “REC/PHO” button. The LED light will flash off, and the camera will then take a single photo. The photo is automatically saved to memory, and then the LED light will come back to a solid/steady light, indicating the U-838 is back in standby mode.

Photo files created in this mode are named “PICTxxxx.JPG” (where ‘xxxx’ is an incrementing sequen-tial integer value, beginning at 0001, and sequentially inclusive of other file types previously recorded). They have a resolution of 4032 x 3024 pixels, and contained EXIF metadata indicating the camera maker as “Syntek” and the camera model as “USB Camera”.

7. To make a Voice Memo

Recording audio sound (without video) is possible with the U-838 device. When the camera is turned on (in stand-by mode, as indicated by a solid/steady blue LED light), press and hold the “REC/PHO” button for three seconds. The LED light will long-flash twice, and then go out (off). The U-838 will now be recording sound, but without video.

Again, the device is recording with the LED off, because it was originally intended as a spy camera, and you don’t want to give it away that it is recording by having a light on.

To stop recording sound, momentary (quick) press the “REC/PHO” button. The LED will return to a solid/steady light, and the U-838 is back in stand-by mode. The file is stored to memory as a .WAV file.

To reenter the audio recording, you have to press and hold the “REC/PHO” button for three seconds. If you do a momentary press, it will just take a still photo.

Audio files created in this mode are named “PICTxxxx.WAV” (where ‘xxxx’ is an incrementing sequen-tial integer value, beginning at 0001, and sequentially inclusive of other file types previously recorded).

8. To Turn On and Off the Infrared lights

While the camera is on (in stand-by mode, as indicated by a solid/steady blue LED light), start a video recording (see step 4 above). While it is recording video, momentary press the “REC/PHO” button. To turn them off, again momentary press the “REC/PHO” button.

To be honest, the infrared lights are useless. For one thing, you can’t see that they are on; they are outside of the visible spectrum of light. It is like the infrared light on the remote of your television. The only way to tell that they are on is to look at the camera with a different camera which can detect the infared spectrum of light. I use the built-in webcam on my computer to verify that they are on, since it can sense infrared light.

The infrared lights are supposed to illuminate a night-time scene. But they are too small to make any dif-ference in the picture quality. You might as well leave them off for model rocketry purposes.

9. Motion Detection

The purpose of motion detection is to save memory by only taking video when something is moving in the view of the camera. Motion Detection mode creates only 1-minute videos, which are activated by some sort of motion past the lense of the camera. That makes this feature useful for capturing wildlife, like deer eating at a feeder, but not so much for model rocketry.

Be careful when using this mode for model rockets flights. There could be a slight lag in activation and it might miss the initial movement of the rocket as it takes off the pad. Be sure to test the camera if you want to use this feature.

To activate motion detection, once the camera is on, hold down the VIDEO (start/stop) button for 3 seconds and the LED will start to blink. You can then release the button. The LED will blink 5 times, then turn off. You are now in motion sensing mode. Remember that the camera will only record in one minute clips. It starts each clip if there is motion present. Each time motion is detected the blue light will flash and start another 1-minute long video.

It will exit motion detection mode when you press the VIDEO (start/stop) button for 3 seconds, the same as with the continuous recording mode.

10. Webcam Mode

When the camera is plugged into a computer, a short press of the REC/PHO button should cause the camera to appear to the computer as a camera, allowing the computer user to use the camera as a web-cam. This was not tested by Apogee Components.

11. Setting the Time Stamp

A. Using a text editor such as Notepad, create a simple text file named “time.txt” and save it in the root directory of the micro SD memory stick. The file should have one line only, containing the current date and time in the following format:YYYY.MM.DD HH:MM:SS X, where “X” determines whether you want the timestamp to appear on the video images.

Use ‘Y’ to include the time in the video/photo images.Use ‘N’ to prevent the time from being recorded on the video/photo images.For example, the following will set the camera’s clock to January 5, 2016, 5:25:35 PM, and have the timestamp displayed in the bottom-right corner of each photo and video:2016.01.05 17:25:35 Y

B. Once the file has been saved to the root directory of the micro SD memory stick, unplug the camera from your computer, turn the camera on and it will read the “time.txt” file, make the appropriate chang-es, and then delete the file.

12. Connecting to your computer

When the U-838 video camera is connected to your computer using the USB socket, your computer

should recognize it just like a simple USB memory stick. While connected to your computer, the illumi-nation light will be a steady color.

You should see several folders on the “removable drive.” The folder called “DCIM” contains the videos and the photos you have taken. Open the folder, and copy the files you wish to view to your computer. It is better to copy the files before trying to play them, as they will play with less choppiness.Use your computer to delete the video files from the T/F card to free up memory space to take more videos. The camera can also be used as a memory disk to hold and transfer files.

13. Mounting Options

Because it is such a lightweight camera, you can use strong electrical tape or duct tape to hold the U-838 HD video camera onto your rocket. Be sure not to cover up the operation buttons or the lens of the de-vice. On small rockets, mount the camera closer to the front of the rocket to keep the Center-of-Gravity forward of the Center-of-Pressure. On bigger rockets, you can move the camera rearward to get a more unobstructed view of the ground during launch.
