IP Video Management
A network video recorder can serve as a standalone solution for video recording and management because it includes pre-installed video management software. All NVRs support basic software functions such as monitoring live video, recording video, and searching and viewing archived footage. Different categories of NVR solutions are available for IP surveillance systems of varying types, from small systems requiring only basic functionality, to multi-site systems and large-scale surveillance networks requiring fail over and central management.
Basic Software Features
In an IP-based video surveillance setup, software plays a key role in how you manage your cameras and surveillance footage. IP video software provides basic tools for monitoring, recording, and video management, along with sophisticated functions for intelligent surveillance and system integration. The software can be either PC or NVR-based. Let’s take a closer look at some of the basic functions of video management software.
Since a network camera includes a built-in web server, users can remotely monitor the footage in several ways: either with a standard web browser, via IP video software,or, in some cases, with a cell phone or PDA. Video management software offers the most flexibility in terms of monitoring. Typically, users are provided with different viewing modes, and can monitor live and recorded video images from multiple cameras simultaneously. Many software programs also let you remotely adjust camera settings and control functions such as pan, tilt, and zoom commands for detailed monitoring.
With video management software, you usually have several different recording modes to choose from. Examples include continuous recording, scheduled recording, and event-triggered recording. The advantage of recording on a schedule, or having it triggered by specific events, is that storage requirements and bandwidth usage are reduced. You can also conserve storage space and bandwidth by configuring different frame rates for live monitoring and recording. For instance, you can program the system to only use full frame rate during event-triggered recording to guarantee high-quality video footage at the most important moments.
IP video software makes it easy to search and playback recorded surveillance footage on demand. This is one of the key benefits of a digital IP video solution, as archived footage is searchable by date, time, location, or event. With video management software, you can view recorded footage in separate windows, and in many cases, multiple authorized users can access the video images at the same time. The software also provides tools that allow you to zoom in for closer inspection and detailed analysis of your archived video.
If you've ever heard the term “intelligent surveillance,” it’s referring to the use of sophisticated video analytics to detect specific, pre-determined activities. This advanced level of video analysis takes place either at the front-end within the camera, or via IP video software. The goal is to achieve preemptive surveillance, meaning you’re not just reviewing footage after the fact, but actually detecting suspicious activity as it happens.
While the technology is still being developed, it’s already widely used for a number of functions including advanced motion detection, license plate recognition, audio detection, facial and behavioral recognition, and detecting acts of graffiti, vandalism, or situations where an object is suspiciously left behind.
