Most Amazing Facts about POE keypads

POE technology has become very popular over the past few years. One reason for its popularity can be fact that it helps to integrate data and power across the network cables. This helps to provide flexibility as the integration can be done over the existing network cables and devices like IP phones, cameras etc. using a single network cable.

In addition, if the network is supplied with uninterrupted power supply then continuous operation can be delivered. The elimination of power interruption also helps to decrease the downtime. The POE keypads also give the ability to install endpoints in any location. This helps to provide flexibility and scalability to the networking infrastructure and helps to maximize the growth and efficiency. A number of options are available that can be availed to make these keypads fully optimum for the required environments.

Most of the keypads are POE enabled, today. They can share the available power across the switch ports. They have small power supply and are also capable of powering the switch. They can provide power over a number of ports. In fact, many devices that do not allow Power over Ethernet can also use these keypads. A Poe splitter can also be used if less than 50 watts is used by the device. It can also be used to connect the keypad to an IP Ethernet network. This helps to separate the power and the data on to two separate cables.

Today’s POE keypads are highly efficient and get easily integrated with the existing networks. They are also called as rugged keypads as they can be installed in all types of climatic conditions. These also allow separation of the power and the data using the wiring closet. This is very efficient and also costs less. These outdoor keypads can be used over all types of networks. That’s why these are also called as network keypads. These can be integrated with the old as well as the new technologies.

Advanced Access Control Keypad Features

The latest advancement in the access control applications is the digital keyless entry system. These are great for single entry point applications. These keypads can be used in wide range of applications like door locks, automatic gates etc. Each individual is assigned a code and he has to enter that code on the keypad to get access. This way only the authorized personnel are able to get access.

Most of these keypad displays have a backlit keypad that illuminates when in use. These keypads have embedded LEDs that provide the incandescent lighting. The duration of this lighting can also be programmed. The number of access codes to be stored in the keypad can also be programmed. The modern keypads also continue to work properly in case of a power loss as well. There is no effect on the state as these have a non-volatile memory that remains unaffected during the power loss as well and hence, no data is lost.

Most of the modern access control keypads also come with other characteristics like:

1. Timer

2. Sound preferences

3. Security responses for invalid code entry

4. Reprogrammable memory

These keypads do not require a separate programmer. Most of the programming is done at the keypad. Some of the keypads are even able to store more than 500 access codes. These can also be called as rugged keypads as these come with a metal housing that protects the keypad. This housing also helps to seal out the moisture. Also, independent output actions for each access code can be programmed. These are also very secure as these have no external wiring that can be cut by intruders. This fact makes these outdoor keypads apt for office buildings, commercial places, apartments, parking, industrial areas etc. These have an auto-relock feature that gets activated as soon as the door is closed.

Serial over Ethernet keypad applications

Keyboards are the most widely used input devices. Despite advancements in the input technology and entry of devices like mice, touch screens, voice recognition etc, these are still used extensively as the human-machine interface. The basic working of all the keypads is same. These have keys that have printed or engraved numbers, symbols, words, letters or images, which when pressed act as switches. These switches send instructions to the machine.

Embedded computers and microprocessors are extensively used nowadays. These use serial ports and support serial communication. These use serial over Ethernet keypads. In microprocessors, serial ports called as UART (Universal Asynchronous Receiver Transmitter) are used. These are used in coordination with a line driver chip. Almost all of the microprocessors have the hardware provisions for serial communications. These serial over Ethernet keypads act as an excellent connectivity option between interface technologies and embedded microprocessors. It helps to make these technologies easy to implement. These have COM ports into which these keypads can be plugged in and used.

Network keypads, serial over Ethernet, outdoor keypads etc. are all on the rise in use. These are used to connect the network devices to the Wi-Fi or Ethernet. Most of these keypads can synchronize with PCs, whole house lightings, iPods etc. The user can connect as many components over the LAN (Local Area Network) as one wants. These components are IP controlled.

The popularity of serial communications is massive and so is that of internet display keypads, serial over Ethernet keypads and access control keypads. Most of the keypads available today in the market are designed to work in the harshest of conditions. These come with a metal housing as well and so are called as metal keypads as well. These are very apt for the outdoor and extensive conditions like military etc. These are also suitable for high security applications and can be used in any system. Their characteristics like vandal-proof, water-proof and weather-proof further increase their applicability. These are apt for all the Ethernet applications as well.

Metal keypad details

Metal keypads are a huge rage nowadays. One reason is that they are highly resistant to harsh conditions, contaminations and liquids. Their front panels are completely metallic. This makes them vandal proof as well. All the electronics are contained inside the housing of the keypad. Some of these may even have volt free relay contacts. This helps in the direct operation without any need to fit additional relay contacts.

These rugged keypads may meet meet the protection classes of up to IP 67 and IK 07. They can provide high operating convenience and also, a pleasant touch. The design options are also very large. They have a robust metal construction. Also, the backlit keys make them easy to use even in low light conditions. They are also used to flash different access permissions.

The installation of all the metallic outdoor keypads is almost the same and fairly simple. It contains several wires connecting it to power supply etc. Most of the cables exit centrally from the back, which makes it very simple for drilling and mounting them. They also contain a terminal strip making it ideal to be connected to the external wiring. The settings and the codes can be programmed via the keypad. Some may also have relay contacts that can be used for triggering devices. Many companies also offer the choice of choosing between metal mounting plate and metal surface mounting box.

Metal keypads are perfect for use in areas that are susceptible to vandalism. The metal housing gives a durability to the keypad that the plastic casing can never give. These are also supplied with security tools that help to prevent these keypads from being tampered. Theses keypads are ideal for use in delivery depots, construction sites, external gates or barriers and other vandal prone areas.
