Hardware is used to capture the lecturer's voice along with the video of the lecturer. Sometimes, the lecturer may use visual aids to support their speech, such as slide shows, which are presented to the public with some kind of projector; in this case such slide shows can also be recorded. Once captured, the data is then either stored directly on the capture hardware or sent to a server over a LAN or the Internet. After some processing to adapt the video formats to the desired distribution mechanism, codecs, etc., viewers are then able to remotely access the recording, either in real time or ex post facto.
The recording of a lecture or presentation may use any combination of the following tools:
Software is used both on the capture hardware, the viewer's computer, and the production server. Software ranges from simple web browsers and video players to stand-alone software programs made specifically for viewing lectures. The viewer's as well as the presenter's software must be compatible with the software on the server which receives the content from the capture hardware, produces it, and sends it to the viewer's computer on-demand.

- Traditional Classroom Replacement - Some institutions may use lecture recording as a means to replace the traditional classroom with an online classroom.
- Supplemental Educational Resource - Some institutions may use lecture recording to create reference material as a means to supplement the in-class lectures.
- Non-Traditional Uses Outside the Classroom
- Advertising - Allows for sales and marketing department heads to disseminate information to staff as well as department staff using the technology as a means of reaching their customers.
- Collaboration - Meetings and conferences can be recorded for future reference, dissemination to those not in attendance, and archival.
- Training - New employees, students, and others could be trained using recorded trainings

- Security - Security issues could include deciding who is responsible for housing the lectures, who may be allowed access to the lectures, and for how long that access may remain available.
- Copyright Law - Copyright law originally dictated that copyrighted material could be used for instructional purposes at nonprofit educational institutions but only for face-to-face teaching. However, with the addition of the TEACH Act, this fair use applies to digital lectures as well.
- Classroom Attendance - One major issue facing professors, instructors, and educational institutions at-large is the possibility of classroom attendance plummeting with the advent of lecture recording. Studies show an overwhelming number of students believe the recorded lectures, when used in environments where traditional face-to-face learning is practiced, is not used as a replacement. Students believed the notes taken during class could not be replaced with a recorded lecture but rather the recorded lecture was used for areas of the lecture that needed reiteration.
Lecture captures are becoming increasingly popular especially with advent and rapid growth of MOOC sites like Coursera, Udacity an edX. However, not much research has been done to provide guidelines for recording and presentation of lectures which would be useful for learning.
REC:all (Recording and Augmenting Lectures for Learning) is transnational learning technology project supported by the European Commission under the Life Long Learning Programme, it aims to explore new ways in which lecture capture can become more pedagogically valuable and engaging, and is investigating a variety of learning design, technical and legal issues.

Built-in automation and integration capabilities make Echo360 easily adjustable for any type of environment: from one single class room, an entire school campus, or multiple campuses regardless of location. The software solution allows instructors to record their lectures from anywhere. Professors can lecture from classrooms, offices, or their own homes. EchoSystems requires that special software be installed on each computer used for capturing lectures. Echo360's solutions allows users to capture lectures through any camera, microphone, or sympodium.
The latest version of the EchoSystem Server (ESS) is 5.4. This version allows users to view lecture from any computer as well as from an iPhone or iPad. All lectures can be recorded in HD with high quality audio. A new feature called lecture collaboration allows users to take notes on the lectures, as well as join discussions with classmates. Lecture collaboration creates a collaborative online experience for all of the users. Students can use this tool to ask the professor any questions they might have about the lecture.
The EchoCenter is where users login to access the material. From the center each lecture is shown in a playlist organized by the date a lecture was uploaded. This center allows professors to follow class discussions and track all of their captured lectures. The ESS enables a central IT department to support a single backend server infrastructure to cover the entire campus. This allows separate departments within an organization to decide if and how to implement this system.
Echo360 is also able to combine with other software. Echo360 and CaptionSync were combined to create a seamless software used by many universities. This version is able to view handwriting inputted by a tablet computer or other touch device and posts the writing under each lecture. This allows Echo360 to be used for math and science classes where there are calculations.

The Galicaster Project is an open initiative, supported by Teltek Video Research (a start-up company born at the University of Vigo, focused on providing open IT-media solutions for Academia) to provide a flexible, state-of-the-art solution for recording educational multimedia contents like lectures and conferences. This solution basically consists on a Linux-based application and a set of hardware recommendations for the computers to be running such application. Some important features Galicaster provides are:
- Live visual feedback of what is being recorded, including a vumeter for audio monitoring.
- Remote monitoring of the recording, via VNC.
- Ability to browse, play, delete or download finished recordings (also in an Opencast Matterhorn-compatible format).
- Recording may be triggered automatically or manually.
- Basic recording controls (start, pause, stop…)
- Compatibility with Opencast Matterhorn schedule and ingestion services.
- Touchscreen interface.
Galicaster supports two operation modes:
- Galicaster Class: Works as an automated recording system for classrooms and unoperated conference halls. Recordings can be scheduled and they will start and stop automatically at the configured times. Lecturers/teachers don't need to interact with the recording if they don't want to, however they have access to a restricted interface that allows them to pause, resume and stop the recordings, even those started automatically. Media browsing and reviewing capabilities aren't enabled in this mode, so that the interface remains as simple as possible.
- Galicaster Mobile: All the Galicaster features are enabled, so that the user can manually start/pause/stop recordings, edit their metadata, review recorded media, etc. This operation mode is intented for video operators that need a simple yet versatile mobile unit to record in unequipped halls or classrooms.
It is based on cognitive learning theories and the concept of rich lecture captures. Its aim is to compensate for intrinsic deficiencies of lectures as a teaching tool and to present recorded lectures in a fashion that supports learning congruent with cognitive learning theories.
LeCTo offers a simple recorder able to record desktop activities and virtually unlimited number of (external) video devices. Each video is stored in a separate file. Videos recorded by other tools can be used as well.

The Opencast Community is a collaboration of individuals, higher education institutions and organizations working together to explore, develop, define and document best practices and technologies for management of audiovisual content in academia.
The Opencast community also supports community-driven projects to solve common issues in management of academic audiovisual content as identified by the community. The most prominent of such projects is Matterhorn: a free, open-source platform to support the management of educational audio and video content. Institutions will use Matterhorn to produce lecture recordings, manage existing video, serve designated distribution channels, and provide user interfaces to engage students with educational videos.
As of 2012, Panopto offers two units of software—Focus and Unison. Focus is software that records and live-streams presentations, lectures, demos, and so forth, and then stores them in the Panopto video content management system. Unison is software that imports existing videos into the Panopto video CMS. Both Focus and Unison come with the web-based content management system, a web-based media editor, the ability to search within videos, and developer APIs for integrating Panopto with existing content- and learning-management systems.
In 2010, Learning Valley a startup company born at Wageningen University in the Netherlands did research together with University of applied sciences Utrecht into 'Live Tagging' applications in combination with rich media weblectures. This enables students to make online tags (notes) on mobile devices such as iPhones, iPads or netbooks, etc. during a lecture. Using clever, innovative technology, the positions of these tags are accurately linked to the teacher’s presentation slides. When the lecture is over, the notes can be seen on the time-line for the web lecture or webcast recorded using Presentations 2Go. This enhances and enriches the content.
With the new release of Presentations2Go, teachers and students can now also add notes retrospectively when viewing a web lecture. Presentations 2Go makes a distinction between ‘moderators’ (teachers) and ‘audience’ (students). Moderators have extra possibilities. They can introduce command ‘tags’ which can be responded to. In this case, the video recording pauses and an optional link automatically opens in a separate window. The ‘assignment tags’ that are handed in are only visible to group moderators. It’s also possible to enable students to react to each other’s notes. When watching the web lecture again, notes can be filtered using keywords and downloaded in HTML format. This means they can be utilised usefully within existing learning environments or locally.
