Network POE Switch

A Network POE switch is a network switch that has Power over Ethernet injection built-in. Simply connect other network devices to the switch as normal, and the switch will detect whether they are POE-compatible and enable power automatically.

Cat5e VS Cat6

Short for Category 5 Enhanced, Cat-5e network cabling is used as a cabling infrastructure for 10BASE-T (Ethernet), full duplex 100BASE-TX (Fast Ethernet) and 1000BASE-T (Gigabit Ethernet, or GbE) networks. The Cat 5e standard provides performance of up to 100 MHz and can be used up to a maximum length of 100 meters.

As with Category 5 (Cat-5) cables, Cat 5e cables typically consist of four unshielded twisted pairs (UTP) of copper wire terminated by RJ45 connectors. Cat 5e is distinguished from the original Cat 5 standard primarily in its performance requirements. Cat 5e has stricter specifications in a number of areas, including Near-End Crosstalk (NEXT), Power Sum Equal-Level Far-End Crosstalk (PS-ELFEXT), attenuation and return loss.

Category 6 cable, commonly referred to as Cat 6, is a standardized twisted pair cable for Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards.
Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for crosstalk and system noise. The cable standard also specifies performance of up to 250 MHz compared to 100 MHz for Cat 5 and Cat 5e.[1]

Coaxial Cable

Coaxial cable, or coax (pronounced /ˈkoʊ.æks/), is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English engineer and mathematician Oliver Heaviside, who patented the design in 1880.[1] Coaxial cable differs from other shielded cables because the dimensions of the cable are controlled to give a precise, constant conductor spacing, which is needed for it to function efficiently as a transmission line.

Hard Disk Drive Storage

Hard Disk Drive Storage is a data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile storage, retaining stored data even when powered off.

Camera NVR

A camera NVR is an NVR-based camera system. A network video recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware.

Camera NVR can record video streaming transmitted through a network cable. IP cameras can connect to an NVR through internet or LAN network. There are instances when, without the use of NVR, end-users can still use IP cameras and installed VMS or video management software to setup their IP surveillance systems.

Camera DVR

A camera DVR is a security system which links one or more cameras to a digital video recorder. It's main advantage is that it can record for much longer periods without the need to change tapes.

Camera DVR has a performance similar to a video en-coder which works solely with an analog surveillance camera. This also receives an analog video signal and compresses with H.264 standard and records to an HDD or hard disc drive. Connection between an analog camera and DVR makes use of the coaxial cable. With analog technology seeing rapid developments, there are now a lot of HD analog technologies introduced in the market. The latest HD-CVI and HD-SDI recorders, HD-CVI an HD-SDI DVRs have the ability to record analog videos in high definition resolution which include 1080P and 720P format.

Camera Hybrid NVR/DVR

Camera Hybrid NVR/DVR can be standard analog cameras or IP/network cameras that uses Hybrid video recorders (HVR). The HVRs can be a little misleading at first. An 4, 8 or 16 channel Hybrid aren't really 4, 8 or 16 channel video recorders. You’ll want to double check, but most sellers of these recorders advertise them in the same way. The channel quantity that’s listed is almost always the channel quantity for each type of camera the recorder is compatible with. What we mean is that an 8 channel HVR is actually 16 (8 analog and 8 IP). If I’m still doing a bad job of explaining this, you’re getting twice as many channels as is being advertised in most cases.
