Many businesses employ CCTV camera systems as a primary tool to monitor staff and visitor movements and to prevent crime. A CCTV, or Closed Circuit Television, is a system of surveillance cameras, data networks and display devices that detects and deters possible criminal activity.
Security camera systems are beneficial for public and private sectors, including homes, healthcare facilities, schools, shopping centres, industrial plants, parking lots and other spaces. In the past decades, the fundamental shifts in gathering, storing and analyzing digital data have significantly transformed the capabilities of modern surveillance cameras.
Integration is one of the prime features of the most up-to-date CCTV systems. In this article, we assess ONVIF integration options offered by Pelco, a global leader in the development and manufacture of video security solutions.
ONVIF stands for Open Network Video Interface Forum. The security industry created an ONVIF open standard protocol to facilitate camera communication with network recording devices and with each other. ONVIF standard has various versions of compatibility defining which features could be included in the system.
Thanks to ONVIF specifications numerous manufacturers ensure a consistent way for their security devices to work together, even where they would not have been able to previously. These ONVIF standards function as a common language for communication between all devices.
One of the common misconceptions is that ONVIF and RTSP are the same things. However, these notions are of a different order. RTSP (Real Time Streaming Protocol) is a protocol for video and audio streaming, whereas ONVIF is a security standard. The ONVIF standards determine how a protocol RTSP will work to make products across brands work and interface seamlessly.
There are multiple profiles (ONVIF A, C, D, G, M, S and T) that make it easy to understand how clients and devices are compatible with one another. An ONVIF profile has a particular set of features that the conformant device and client must support.
Profile A applies to access control devices providing an opportunity to configure access credentials, rules and schedules.
Profile C applies to door control and event management. Its conformant clients and devices support alarm management, site information and configuration.
Profile D supports interfaces for access control peripherals such as token readers (keys, cards, mobile phones), keypads, biometric readers, CCTV cameras (face or license plate recognition), and sensors (temperature or motion).
Profile G applies to IP-based CCTV systems. A device with Profile G protocol can record video data on its own or over an IP network. A client, for instance, a video management software, can request, configure, and control video recording over an IP network from a conformant device.
This profile supports information query and analytics configuration for metadata, streaming and filtering. Profile M provides interfaces for specified metadata (geolocation, license plate, vehicle, human face and body) and generic object classification.
A Profile S video encoder or IP network camera can send video data over an IP network to a client supporting Profile S. The client can request, configure, and control video streaming from a Profile S device. Additionally, Profile S supports ONVIF specifications for audio in and PTZ control for conformant devices and clients.
Devices and clients use Profile T protocol for advanced video streaming features such as Bi-directional audio, imaging settings, alarm events and the use of H.264 and H.265 video compression. Pelco Fisheye and Sarix Multi ProIn-Ceiling Mount cameras are examples of Profile S, G and T-compliant devices.
Integrating your business CCTV helps get more out of your security investment. Pelco cameras utilize an open platform. Thus, they can flawlessly integrate with any third-party VMS (Video Management System). Pelco surveillance camera integrations to Genetec and Milestone are certified. Furthermore, all CCTV cameras are Profile S and T compliant, whereas cameras with local storage are G compliant, and some are M compliant.
