• ability of <strong>in</strong>stant change of look<strong>in</strong>g direction, OVAD, unlike <strong>in</strong> rotat<strong>in</strong>g cameras<br />

which are limited by drive time of servo-motor, moreover time of change<br />

does not differ<br />

• OVAD can be few times cheaper than rotat<strong>in</strong>g cameras dedicated for <strong>UAV</strong>s,<br />

• absence of mov<strong>in</strong>g elements – utiliz<strong>in</strong>g of rotat<strong>in</strong>g camera may be problematic<br />

<strong>in</strong> difficult weather conditions, such as large poll<strong>in</strong>ation, which may cause<br />

blockage of mov<strong>in</strong>g elements and because of that los<strong>in</strong>g all functionalities of<br />

device. Furthermore, blockage might lead to overheat<strong>in</strong>g of servo-motor, which<br />

eventually may cause irreparable damage,<br />

• huge perspectives on further improvement of device – overall concept is very<br />

adaptable and this feature makes a lot of space for <strong>in</strong>novations , such as extend<strong>in</strong>g<br />

field of view <strong>in</strong>to half-sphere by utiliz<strong>in</strong>g of more cameras or us<strong>in</strong>g digital<br />

cameras (together with FPGA board) <strong>in</strong>stead of analog ones (that would create<br />

a possibility to make device a lot smaller).<br />
