T24: Hemispheric IP Video Door Station

Better Overview, Increased Security, More Possibilities

Door stations with integrated cameras have been around for years. They are almost always based on analog TV technology that is over 60 years old and, because of the system involved, can only deliver very low image quality. Such systems only enable limited two-way communication. The station is installed using a complex cabling and power supply system.

The new T24 IP Video Door Station from MOBOTIX offers a modern, powerful solution that is easy to install and that has never been available to the market until now.

Hemispheric HiRes Camera

Thanks to the Fisheye lens with its 180° image angle, the camera records the entire entrance area without mechanical panning or tilting – without any blind spots, from wall to wall, floor to ceiling. It is not possible to "sneak past" this camera. The current image section can be switched in seconds on the monitor located at the remote station: from a close-up of the visitor all the way to an overview panorama.

The T24 has an integrated high-performance computer, just like the MOBOTIX security cameras used in banks and airports. This enables the IP Video Door Station to start recording video and sound automatically when motion is detected while sending a message to the property owner or security company via text message or email.

Superior Overview Increases Security

The Fisheye lens of the camera records the entire hemisphere of the scene in front of the lens without any blind spots and displays this image in the first step as a 360° full image. For technical reasons, the geometric shape of the objects is heavily distorted, particularly at the edges of the image, making them difficult for the human eye to evaluate. For this reason, the camera uses its integrated software to correct the images

already in the live view so that it can deliver user-friendly images at the remote video station. The images can now be digitally tilted, panned and zoomed into from the comfort of the remote station.

Perfect Overview
The T24 enables a hemispheric 360° Panorama view. The camera records the entire entrance area in wide range and without any blind spots. The fisheye effect, which is typical for this lens, can be switched off digitally in the live image.

180° Image Angle Coverage With No Blind Spots

Conventional door cameras have a standard 90° lens, meaning that they are only able to record visitors if they stand directly in front of the lens. However, often times the door station cannot be mounted directly next to the door and is therefore offset to the visitor at the door (see drawing below). But even in this case, thanks to its 180° image angle, the T24 delivers perfect images.

Direct Views Up And Down

The Hemispheric camera can do much, much more: it can record the area on the floor in front of the door, the often overlooked area directly underneath the door station. The T24 does all of this using only its software – without any mechanical moving parts or motors, silently, discreetly and without making the visitor feel "observed from bottom to top."

Also, this quick look down is incredibly practical when checking, for example, whether the daily paper is already in front of the door. Of course, it is also possible to look upwards up to under the ceiling as well.

Virtual PTZ (vPTZ)
The image sections displayed here are corrected by the integrated image correction software. The virtual PTZ feature allows you to enlarge or move the image section just like a PTZ camera, but without the need for mechanical moving parts.

Based On Internet Technology

The T24 door station from MOBOTIX uses standard network technology and has a microphone and speaker. When the doorbell rings, a connection is established with an IP video phone or a standard computer via the network. Not only can you access the video and sound from the door station from every room in the house, you can also access the camera from anywhere in the world. And most importantly, visitors and property owners can both speak at the same time with the best possible sound quality thanks to the echo elimination and digital signal processing.

As Many Remote Stations Needed

Thanks to the use of network technology, the T24 is not bound to just one expensive, manufacturer-dependent remote station. Upon request and depending on your particular needs, the door station can be operated and controlled using a standard computer, an IP video phone or a tablet computer.

Simple Use With MxEasy

The convenient MxEasy software was customized by MOBOTIX especially for simple and user-friendly operation of the T24. This free-of-charge program, which is available for download on the MOBOTIX website, turns any computer (Macintosh or Windows) into a multifunctional T24 remote station with a graphical, intuitive user interface in no time at all.

Overview And vPTZ Simultaneously (Live And Search)
The user interface software MxEasy delivers a live video image with two windows as a standard. While the top window remains unchanged and continues to focus on the visitor, the image section in the bottom window can be changed as desired.

A Practical Example

With the T24, the Wiseman family from Frankfurt am Main, Germany, always have a clear picture of who is at their door. They installed a modern IP video phone on the ground floor of their house as a remote video station. Using the buttons on the phone, they can quickly and easily control the camera, change the image section through digital panning, tilting and zooming functions, open the door, switch on the light and call up recorded images.

Mr. Wiseman has also set up an additional remote station on the computer at his office in Wiesbaden, Germany. A connection, which includes live video, is established automatically via the Internet whenever someone rings the doorbell and no one is at home. This way, Mr. Wiseman can see the visitor even from his office and speak with him or her, click a button to open the door to let the person inside, for example, if his children have come home from school earlier than expected.

In addition, the family uses a tablet PC, which they leave on the table next to the couch in the evening, allowing family members to speak with the visitors at the door from the comfort of their living room. The family also brings the tablet PC along on vacations so that even from New York, they can communicate live with the visitors at their house in Frankfurt.

Multi-Purpose Video Phone (video: H.264, sound: G.711)
The T24 can be connected to any suitable video phone in the world. In addition to supporting the intercom feature with video and sound, these devices support additional features such as door/light control, image search, quick recording and PTZ functions.

Camera-Internal Memory Up To 32 GB

The T24 saves high-resolution video with lip-synchronous sound directly to the integrated MicroSD flash card, without requiring an external storage device or PC, therefore using no additional network load. Old recordings can be overwritten or deleted automatically after a specified period of time.

A 32 GB MicroSD card can record up to 400,000 Panorama images or 33 hours of video. Flash storage is a mature semiconductor memory technology without any moving parts (and without a mechanical hard drive), and its reliability, simple operation and low costs have made it the storage medium of the future. The MOBOTIX FlashFile system (MxFFS) prevents unauthorized persons from reading or transferring the internally stored data, even if the card is stolen.

Full Image Recording Independent Of Live Image

The Hemispheric T24 has a virtual PTZ feature (pan/tilt/zoom). The live image from the Hemispheric camera can be smoothly enlarged, and you can simultaneous zoom in on any section of the image using a joystick, for example. This is similar to a mechanical PTZ camera, but without the maintenance and wear.

While the live image is zoomed in on a particular area of the image, the camera will continue to record the full image at the same time. This is not possible with any motorized PTZ camera in the world. But it is extremely important for a later research in the recorded events ("Look, there was someone below by the door as well!")

Choose Your Storage Location
Each T24 can be configured so that the camera records either to the internal MicroSD card or to an external network using secure encryption. You can also select the normal hard drive of the PC as the storage location for the camera.

Automatic Event Recording

As the leading manufacturer of high-resolution IP security cameras, MOBOTIX has integrated all of the necessary features also into the T24 door camera. The recording function must be switched on and off manually for standard cameras, whereas MOBOTIX cameras work with intelligent sensor technology and store data efficiently. An automatic recording is started only when, for example

Playing Back Recorded Events

You can use an IP video phone or a computer to call up the events from the camera memory. It is not necessary to install any additional software on the video phone itself. The camera displays a basic operating menu created specifically for telephone keypads directly in the camera image. When using a PC as a remote station, MOBOTIX offers the free-of-charge MxEasy software for convenient setup and operation of the complete T24 system.

Keeping Track Of All Alarms
The alarm search feature combines a host of functions that make it much easier to find specific events. You can also conduct searches using automatically synchronized time tracking. The event that triggered an alarm can be analyzed in more detail in the event view.

Contactless RFID Technology With Transponder
RFID facilitates the automatic identification of visitors and makes it easier to record and save data. An RFID system consists of a transponder (for example, card or key tag) as well as a device for reading the transponder ID (T24 keypad).

Keypad With RFID Technology

Who is authorized into the building and when? The MOBOTIX key module can be used in many different ways. The module is weatherproof in accordance with IP65, meaning that it can be used along with the T24 for professional access control in outdoor areas. The key module enables access via key codes or keyless access using a transponder (for example, as a check card or integrated into a mobile phone). The module communicates directly with the security door opener via MxBus and can be programmed with a time control in MxEasy using the calendar function. It can also be used as an individual module for securing adjoining rooms such as warehouses or VIP areas.

Indoor Security Door Opener

The T24 door station should always be coupled with the MOBOTIX security door opener with decentralized access code memory because they make it impossible to open the door by forcibly removing it and bypassing the connection cable of the T24. The integrated battery (kept fully charged by the T24 using an MxBus cable) ensures that the door can be securely locked and unlocked, even in the case of a power failure. Indoors, the door opener can be on-wall or flush-mounted and thanks to the integrated speaker, it can also be used as a doorbell.

The device is equipped with two colored LEDs for displaying the doorbell and door status (door contact, lock). It can be operated using two buttons: mute button for the doorbell (e.g., during vacations) and release button for the door lock.

Securely Locked Doors
The door openers are normally supplied with power by the outdoor station. By sending signals directly to the electromagnetic door lock, they are not tamper proof. With the MOBOTIX door opener, it is not possible to bypass the connection cable.

Notices Of Absence

The MOBOTIX IP Video Door Station makes your day-to-day activities easier with its integrated message function. The property owner can leave an audio message that is played back automatically when a visitor rings the doorbell. This works just like a telephone answering machine that only plays the audio announcement and does not enable recording.

An example: Mr. Wiseman works as a freelancer, so he meets with clients on a regular basis, also in his office. On busy days, he uses the message function on his MOBOTIX door station so that he doesn't lose clients – especially unannounced and potential new clients – right away. Each visitor who rings the doorbell receives the message that Mr. Wiseman is currently out of the office but that he will be available again on the following day at 9 a.m.

Answering Machine

Alternatively, the property owner can choose to give his or her visitors the option of leaving a video message with sound at the door station. This function also works like a telephone answering machine but you can record a message. In addition, it also plays back a short message automatically when a visitor rings the doorbell. The message will indicate that the visitor can leave a video message with sound by pressing the button with the symbol of a letter.

An example: Now the delivery person or mail carrier can easily let the Wiseman family know that someone stopped by and that the package was left with the neighbors.

Message Box

An additional, especially intelligent message function offers visitors the opportunity to leave a personal message for a particular person. This message is played back once that person enters their authorization via access module of the T24.

An example: Sometimes Mr. Wiseman would like to leave a message for his cleaning staff before someone cleans his offices. No problem: the T24 can play a message specifically for the card holder when the door is opened using the transponder code card.

Multifunctional Keypad
The convenient message function does not have to be ordered separately. This feature comes with each keypad as a standard. The speaker, microphone, camera and memory of the T24 door camera are cleverly used as part of this system.

Playing Back Messages
If a visitor has left a message for the property owner, it will be indicated by a flashing LED on the T24. The message can be played back at the door station after the appropriate person has entered the security code. Video messages can be played back at any of the remote video stations.

T24: Build A Network Quickly, Easily And Cost Effectively

What does a typical system look like and what kind of cabling is needed? The system image shows the schematic structure of an access control system with the T24 including the Hemispheric camera, keyless entry, info module and an additional security door opener from MOBOTIX for inside installation next to the door. The T24 network connection and power supply are supplied via an Ethernet cable (PoE technology) or alternatively using the Mx2wire expansion set via a two-wire bell wire. This way, the existing doorbell or simple door intercom system can be replaced by a versatile access control system with a high-resolution MOBOTIX door camera with little extra effort or cost.

Fast, Simple Installation
In new constructions, MOBOTIX recommends connecting a CAT7 cable directly to the door station. In renovations of older buildings, the existing bell wires can be used further together with the Mx2wire technology (also with Siedle Vario).

Simple Connection Of Individual MOBOTIX Modules

The T24 outdoor station requires just one cable for data and power (via a CAT cable or two wires with Mx2wire) to connect to a PoE switch and thereby to any expandable Ethernet network. In addition to the outdoor station, you can also install additional modules indoors that can connect to the T24 over the network via a switch or MxBus. In this way, the keypad is also the perfect access module for adjacent spaces or rooms. Or you can use a transponder card to switch the alarm system in the building on and off. Additional MOBOTIX modules are currently in development.

Info Module With Mx2wire Technology (Renovation/Older Buildings)

The MOBOTIX info module for the T24 outdoor station is not only a weatherproof module with a backlit house number field lit by economical, long-lasting LEDs. It can also be ordered with an optional Mx2wire unit. This unit is needed if the T24 is to be connected to the PoE switch with an existing bell wire via a second Mx2wire unit instead of directly using an Ethernet cable.

The Mx2wire technology was developed by MOBOTIX and is characterized by the fact that it is able to transfer data and power simultaneously using two-wire cables such as bell wire, coaxial cable, etc.

Hemispheric Video For Siedle Vario

The T24 modules were engineered by MOBOTIX to be retrofitted into the Siedle Vario module system at little additional effort and cost. The individual Siedle modules are integrated into the system using a specially-developed MOBOTIX IO terminal board that can be clicked directly into the Siedle module located directly below the MOBOTIX camera module. MOBOTIX offers the modules in four Siedle colors.

T24 Camera Fits Into The Siedle System
The camera module of the T24 IP Video Door Station physically fits into the Siedle Vario module system and can be used with most modules such as doorbell keypads, motion detectors or lights via a special terminal board.

Custom Modular System

The T24 is based on a modular system that can be adapted to suit the customer’s individual desires as required. Because of this, the T24 system is suited for both private and commercial use. This highly robust and weatherproof outdoor station (IP65, suited for -30 to +60°C, or -22 to +140°F) is available in four attractive colors: white, silver, dark gray and amber.

The Hemispheric T24 camera module with compatible installation frame is an affordable, ready-to-use starter door station, thanks to its integrated doorbell and light buttons, the high-quality microphone and the powerful speaker. MOBOTIX offers solutions for one, two or three modules in flushmounted or on-wall models. The sturdy frame can be ordered with an optional integrated anti-theft device that prevents the modules from being removed easily.

Standardized Network Technology
Connection to the T24 is established using a normal computer network and not using a video cable. This has the advantage that access can be granted from anywhere in the world using affordable standard fiber optic, copper and wireless IT components.
