This article reviews the important camera specs, and how to avoid being fooled by specsmanship (from the marketing department). A variable lens can be manually adjusted through a range of angles. “Back focus” is not part of the lens, but is usually listed with the lens specification. IP cameras are Digital and connect via Cat5 (Networking) Cable or WiFi. The 1080p HD camera has at least 1080 vertical pixels (or horizontal lines). The f-number will also appear as part of the minimum illumination spec. The iris affects the depth of field. The Microsoft sample capture program AmCap can be used to test general connectivity with webcams and analog camera cards and devices (not network cameras). At night it opens the iris and when there is bright sunlight it closes the iris. After identifying them, you can mount the camera and junction box, please note that some cameras may have a deep base for cable management, but this particular camera needs a junction box to hide cable connections like RJ45 connectors and power leads. The minimum illumination is the lowest light level that provides a reasonable image from the IP camera. P-Iris lenses are similar to the DC auto iris lens, except they add additional intelligence to the lens opening. Does DVR/NVR Use a Lot of Electricity. The resolution of a camera is defined not only by the sensor, but also the lighting, lens and the electronic circuits. We are an engineering and consultation company that sells complete IP security solutions at the very best prices. The relationship between the horizontal and vertical pixels is called the aspect ratio. Today resolution is defined by the total number of pixels in the sensor or the horizontal and vertical pixels. The minimum illumination level is also determined by the lens. The most important aspect of installing a CCTV camera … Combining low-light monitoring capabilities and high-definition recognition, Hikvision smart IP cameras can easily meet the requirements of enterprise projects.
