It will then combine these exposures to balance the lighting in both areas.

It does this by creating different exposures - over-exposed and under-exposed. The HDR feature will try to compensate for this to allow for some visual details outside without affecting the interior lighting. On one hand, the inside of the building will be appropriately exposed, but on the other hand, a window in the background will be completely over-exposed (or vice-versa - the camera will be able to see slight details outside, but the interior will be too dark). A typical example of when this technology is especially useful can be usually found when using a security camera indoors.

Cameras with this feature use a special HDR software to help balance these differences. The difference between the brightest section and the darkest section of the scene is referred to as the dynamic range. really bright areas and really dark areas in the same scene). The purpose of HDR technology is to compensate for high contrast lighting issues (i.e. This allows you to choose either a wide angle view, which will let you see most of the scene in front of the camera, or a narrow, zoomed in view of one area in particular (like a cash register). On the other hand, our motorized varifocal cameras can adjust their field of view anywhere between 2.8mm (wide) and 12mm (narrow). For example, our ultra-wide security camera uses a 2.6mm fixed lens. A shorter focal length will have a wider field of view while a longer focal length will appear more narrow and zoomed in. The focal length (measured in mm) determines the field of view. A further important distinction between different types of lenses is the focal length. Fixed lenses cannot change their field of view while varifocal lenses allow for field of view adjustments within a range. In general, lenses can be classified as either fixed or varifocal. Some varieties of security cameras will use one type of lens, while another variety will use a completely different type. There is no standard lens for our security cameras. If more distance is needed (especially outdoors) Lorex offers range extending antennas that can boost the signal up to 800ft. Indoors, on the other hand, is much less (around 165ft), since the signal will have to pass through walls and other materials. As a general guideline, we state that in ideal conditions (outdoors, with a clear line-of-site) the maximum wireless range of wireless security cameras is 500ft. Factors such as building materials and the amount of other devices using the same wireless frequency (WiFi routers, cordless phone systems, etc.) can affect the strength of the signal significantly. The distance for wireless security cameras and their DVR or wireless transmitter isn't as strict as MPX and IP cameras. For more distance, you will need to purchase a PoE switch, which can extend the range another 300ft. Similarly, IP cameras can be installed up to 300ft away from the NVR.

It is possible to extend this video range further, but you may start to encounter some signal degradation. For cameras over that distance, you can still run a BNC cable up to 800ft, but the camera will need to be plugged in near the camera. This set-up allows you to plug your MPX cameras in close to the DVR, since power for the camera is carried over the Siamese cable.

The Siamese BNC cables used with analog DVR systems can be used up to 300ft. The distance that a security camera can be installed from the DVR or NVR varies.

If not, you will have to pair the camera through the mobile app. Wire-Free cameras typically come pre-paired with the DVR. They are installed by attaching the wireless transmitter to the BNC ports on the back of the DVR. You can then run the single Siamese cable to the MPX security camera. To connect this cable, you will have to connect one end of the cable to the DVR (Digital Video Recorder) and the other to the included power adapter (which can be plugged in beside the DVR). This type of cable splits into two ends, one for video and one for power. MPX systems, on the other hand, use RG59 Siamese BNC cables. This cable provides video transmission and power to the camera thanks to Power-over-Ethernet technology. Digital IP security systems use a single Cat5e Ethernet cable to connect the NVR (Network Video Recorder) and security camera up to 300ft. Lorex offers four different types of systems - Digital IP, Analog MPX, Wireless, and Wire-Free. Installation depends on what type of security camera system it is.
