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.

Internet Display buying tips

The popularity of internet display can be summarized from the fact that rate of advertising on these is continuously increasing. While in Europe the increase in the rate has been only 10.4%, the figures are considerably higher in Latin America and Asia Pacific. In Asia-Pacific the rate has been around 33.2% while in Latin America, it has been 48.2%. Apart from internet display, outdoor keypad advertising has also increased by almost 4.3 percent.

Most of the revenue of internet display advertising comes from direct response campaigns. These account for three-quarters of the whole display advertising. In these campaigns, visual advertisements are presented to the target audiences. These advertisements are called “ad”. They help to increase the revenue of short-term sales.

These give great performance when used in control devices. These have both-tactile and non-tactile response. The responses help to reduce the operation time. Other major feature of these keypads is that these have embedded LED’s like the ones used in outdoor keypads. LED’s are light emitting diodes. These LED’s help to give high end visibility during low lighting conditions. This helps to operate these devices efficiently in such conditions.


Before buying an internet network keypad, keep the following points in mind:

1. Always try to get all the information about the brand, before you buy its products. Avoid poor brands
2. Get the basic information of the brand from the website and only buy their products, if you feel that they are true and genuine. You will also get the basic knowledge of the technologies used from their website.
3. Read all the testimonials and the other client’s reviews about the brand. This will help you to know about their service and no way is better than getting information from the other customers.
4. Also, compare the prices of a brand with the prices of the other brands of rugged keypads. This will help you to decide whether the prices of the brand are reasonable or not.

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.

Network Keypads information

Network keypads have seen great advancement in their technology. Modern keypads even come with the ability to audio-video components, PCs, iPods, Whole house lightings, energy management devices etc. These come with the ability to attach as many IP controlled components over the Local Area Network (LAN) as the user wants. The components are controlled by a serial.

These can be used to control the lightening in the whole house. There is no need for expensive black boxes or exotic wiring. The whole lightening can be controlled by a control customized in the form of a URC dimmer or switch. The user can completely control by dimming, brightening or recalling various scenes without the help of any PC or programmer. The settings can be adjusted manually.

In order to enjoy the RSS feeds, the LAN has to be connected to the internet. These keypads can also be used to control a metal keypad device as well. These devices are powered by a PoE injector. In addition, these are provided with slim and narrow, aluminium alloy housing that is most suitable for doorframe mounting. This housing provides durability to the keyboard and resistance to vandalism.

Most of these keypads are vandal resistant and are designed in a way to function properly in the most hostile environments. These can be used as outdoor keypads as well. These are in particular apt for high security applications. These come with an open protocol and can be used in any system. Redundant connections like UDP and TCP are also available with many of these. There is an integrated web server that can be configured and reset.

Many network keypads also come with an optional transmitter. In all, theses keypads let a user to make a local stack of components using a low cost wireless control. These are also compatible with third party access control keypads.
