This version outperforms all previous PKI A/V recording systems. This PKI 4950 A/V Long Term HD Camera is only possible thanks to the additional rechargeable Li-ion battery of 3.7 and 18Ah power. The use of the 32GB micro SD card enables 90h of A/V surveillance and this with the smallest possible dimensions of 51 x 31 x 11mm, without external battery as it can be separately installed via the 1 m cable. All A/V information is stored on the micro SD card. For A/V playback, it can be taken out and be analyzed using a computer, i.e. A/V recordings can be watched and listened to. It is also possible to connect the PKI 4950 A/V Long Term HD Camera to the computer using a cable.
