The MA9321-EHTV from Vivotek is a 20 Megapixel Day/Night Outdoor Network IP Dome Camera, 3.7-7.7mm Lens. The new MA9321-EHTV is the most versatile product offering to date from Vivotek. The MA9321-EHTV provides high resolution images through four independent sensors, and remote focus lenses. By having each sensor independent of each other, the MA9321-EHTV can view four different regions simultaneously and therefore reduce the total number of cameras needed for surveillance, helping to lower total installation time and costs. Featuring four independent 5MP CMOS Sensors, the MA9321- EHTV network camera can provide the most flexibility in surveillance monitoring. Each sensor utilizes a 3.7 to 7.7 mm remote focus lens and 3-axis design along a circular track to enable full 360° coverage. This enables the MA9321-EHTV to capture every angle for comprehensive video coverage from a single IP address, making this camera ideally suited for surveillance in areas such as hallway intersections, building corners, parking garages/lots, and shopping malls. The MA9321-EHTV is equipped with a removable IR-cut filter and WDR Pro technology, enabling the camera to maintain optimal image quality and unparalleled visibility in high contrast lighting environments. Furthermore, the MA9321-EHTV employs Vivotek's Smart Stream III technology and H.265 compression codec, reducing bandwidth more than 90% while still maintaining excellent image quality compared to traditional H.264 without smart streaming. In addition to its versatile coverage, the MA9321-EHTV is armed with a robust IP66 and IK10-rated housing to enable the multidirectional camera to withstand rain and dust as well as to protect against vandalism or tampering.
