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.
