RAID (originally redundant array of inexpensive disks, now commonly array of independent disks) is a data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance improvement, or both. Data is distributed across the drives in one of several […]

A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas. The most common principles for CO2 sensors are infrared gas sensors (NDIR) and chemical gas sensors. Measuring carbon dioxide is important in monitoring indoor air quality, the function of the lungs in the form of a capnograph device, and many […]

Smart Baby monitor, also called Smart babymonitor, is an electronic device that belonging to the wireless home security system for active babies sleep quality testing and so on. It belonging to the wireless home security system and consists of two parts, baby monitors side or baby unit and the control side or parents unit. Put it in the baby's room […]

Near-infrared light is one kind of electromagnetic waves in the range of visible and infrared light which cannot be perceived by human eyes. Near IR Cameras were developed on the basis of this, they refer to cameras with NIR sensors. Compared with DSC, Near Infrared Industry Camera has stable and reliable performance, is easy to install. Because of […]

Video management system (VMS) currently divided into two categories, one is VMS platform hardware manufacturer launched, and the other is VMS software of the software vendor developed. Video management software is typically used to record and manage video surveillance installations. Video management software runs on a computer and allows users to […]

Outdoor TV is built to withstand the ever changing temperatures and lighting conditions of the great outdoors. The easy day/night dimming adjustment adapts to any lighting condition, from the brightest mid-day sun by the pool to the darkest night under the cabana. The TV panel offers a scratch resistant, anti-glare surface to provide a bright, […]

A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to an analog or digital code. There are two main types: absolute and incremental (relative). Absolute rotary encoders provide a distinctly coded numerical value for each shaft position. In positioning tasks […]

A time switch is a device that has a built-in mechanical or electronic timer that turns an electrical circuit on and off at certain times of the day. The electrical current typically is used to perform a task that otherwise would be done by a person. Time Switch work in a variety of areas, such as irrigation or other water pumps, indoor or outdoor […]

InGaAs image sensors are image sensors that contain a CMOS IC readout circuit for easy signal processing. They operate in charge integration mode that accumulates the generated charge to increase the output signal making them ideal for low-level light detection. Applications include photometry in the near-infrared region up to 2.6 μm, such as in […]

Sealed Lead Acid (SLA) Battery, also called Valve Regulated Lead Acid (VRLA) Batteries, are a lead acid battery that has the sulfuric acid electrolyte coagulated (thickened) so it cannot spill out. They are partially sealed, but have vents in case gases are accidentally released for example by overcharging. Sealed lead acid batteries are one of […]
