HikVision HiWatch The HWT-B340-VF is a high-quality outdoor technology bullet camera that can be used for home or business security. This analog camera has a 4MP CMOS sensor and can record video at up to 2,560 × 1,440 px at 25 frames per second. The main advantage of this model is the use of a varifocal lens of 2.8 - 12 mm, allowing the horizontal viewing angle to be varied from 108.4 ° to 32.6 °. The great advantage is the presence of night vision - IR illumination, up to 40 m. Another bonus is DNR technology, which filters out unwanted noise in low light. Of course there is IP66 protection, so the camera is resistant to dust and rain.
