Thank you for choosing our miniature audio video recorder (mAVR)!
µAVR H.264S is an extremely small modern audio/video recorder with a built-in video
camera. The recorder provides recording on SD and SDHC cards and can operate
with a rechargeable battery with a long service life.
Before using, read the instructions carefully.

Overlook
The µAVR-H.264 audio/video recorder is intended for professional recording of
video and audio signals onto ash memory card (up to 32 GB). Then the recordings
can be uploaded onto a computer, decoded (converted), and played back.
The recorder can provide video recording either from the built-in recorder video
camera or from an external source (external video camera, video player, TV video
output, and etc.). Tuning the recorder parameters, you can optimize brightness,
contrast range, saturation, and color.
The recorder can provide audio recording either from the built-in microphone or
from an external one. You can control the microphone amplication manually or by
using an automatic system (mono or stereo).
Along with the information, that all the recorder’s recordings have (the number, the
date and time), you can add additional text (up to 48 symbols) as a note.
Using the recorder settings, you can:
• tune white balance
• reduce ickers with frequency of 50-60 Hz (for instance, from uorescent
lamps)
• set ltration parameters (to reduce small defects in images)
Varying the audio/video quality parameters (compression, bit rate, resolution, frame
size), you can optimize a quality/duration ratio according to your needs.
There exists an opportunity of testing the integrity of video les.
The distinguishing feature of the recorder is a possibility to record an event with its
‘prehistory’ (see Recording with Prehistory).
6
The possibility of working with GPS-receiver as well as correcting recorder’s clock
according to GPS system signal is also preset.
The recorder has an extremely small size and weight, high recording density, low
power consumption, 20 kHz frequency band, and a wide dynamic range up to 92 dB.
The recorder has a built-in clock and calendar with an option to correct their ac-
curacy. With the help of 10 independent timers which the recorder has, you can
set the recording’s duration along with the time, date or weekday when it will begin
automatically.
You can set the recorder’s parameters to start recording when a sound level ex-
ceeds a threshold or when the recorder gets signals from a motion detector.
The recorder LCD shows operating modes and the capacity of recorder’s free
memory space.
You can use the recorder LCD to change the recorder’s settings with the help of the
buttons that are on the front side of the recorder’s case.
Also, you can change the recorder’s settings using the “mAVR_h264_v115.exe”
program.
The recorder can get power supply either from a rechargeable lithium battery or
from an external power source. While getting power supply from the external power
source, the recorder’s rechargeable battery is charging. The recorder can be a
power source for other devices with a 5 or 12 V input (for instance, video camera).

Preparing for Work
Memory Card
To prepare the card for work a card reader is necessary (not available in the ship-
ping box).
For this, follow the next steps:
1. Plug card-reader in and insert memory card
2. Launch “mavr_h264_v115.exe” and select the tab “Setting” in the appeared
window “mAVR-H.264S V1.15 Manager”. Push the button “Setting”
3. In the appeared window “Program Settings” specify memory card path in the
eld “Source data folder” and the path to save the converted video les in the
eld “ Folder for output data”. Press the button “Accept”.
4. Format the card after you choose the FAT 32 le system in Windows or the
µAVR-H.264S Manager program, by pushing the button “Formatting”.
5. After memory card is formatted, specify all the necessary settings and select
“Preparation”. In this case “mavr-h264S_v1.bin” instrumental le will be
recorded on memory card.
6. Insert the memory card into the recorder’s card reader. If you slightly press
for the second time the card will slide out.
Note1: Don’t take the card out while the recorder is scanning or reading it.
Note2: If it is necessary to convert the existing video recording in paragraphs 2 or 3,
specify the path to this video recording
Attention! In case of a changed memory card path (e.g. in case of changing the “let-
ter” of a storage device), it is necessary to specify new path as stated in paragraphs
2 and 3.
