It’s so small but so powerful. That’s the discreet voice activated recorder Cobra DVR-24, which looks just like a typical credit card. Due to its great functionality, excellent sound quality and two very sensitive microphones this spy voice recorder can be classified as a professional ‘top-shelf’ product.
The voice activated recorder in a credit card is an inconspicuous device of with a huge potential. Cobra DVR-24 features excellent sound quality, great functionality and robust design combined with a comfortable and discreet use. The device meets requirements for professional, inconspicuous recorders, and it will be perfect in operational work of law enforcement services or detectives, as well as for anyone who needs an extremely discreet voice recorder, in particular in the business as the form of the device is confusingly similar to a credit card.
The sound activated recorder owes its excellent sound quality to a built-in, extremely sensitive miniature microphone InvenSense INMP441 with a diameter of only 0.3 mm and the advanced microprocessor technology.
After you connect the sound recorder to the computer, a compatible software will ask for the access password. Thanks to this solution no unauthorized person will be able to delete the evidence collected.
Collected evidence is stored in the built-in 2 GB memory. Depending on the settings, that is enough for 12, 18 or 74 hours of recording.
The function of recording upon detecting sound in the vicinity can be adjusted to your personal predispositions. High pitched sounds require one sensitivity, and low pitched sounds and conversations - another.
A very useful function allowing to record in a fixed scheduled mode. The software provides possibility to set a daily, hourly and weekly calendar. It is also possible to record according to the schedule with a VAS function (sound activated recording).
There are no visible power switches or buttons. The device is switched on and off with touch sliders placed just over the chip on the card. To turn the recorder on or off just slide your finger left or right on the card over the chip which serves as a communication port.
The sound activated voice recorder hidden in a credit card is powered by a built-in battery which can be recharged via USB adapter. Thanks to the energy-saving solution recording for up to 135 hours in stand-by mode is possible. To recharge the card, use the USB reader connecting it to a computer.
The sound activated recorder has hidden LED diodes, which shortly signal the start of recording and help in device configuration.
Full functionality is available only after prior complete configuration of the device using Nevo software that is compatible with Windows 7, 8 and 10.
The software also provides automatic and manual sound amplification in the recorded files. In automatic mode the sound in the selected recordings will be amplified at the most, and in the manual mode the use can adjust the amplification to his needs.
The format of the professional voice recorder Cobra DVR-24 matches the standard credit card dimension 85.6×54.0 and thickness 1.6 mm. The card is white as a standard, but on request it can be made with graphics imitating a paying card.
