Edge Technology Options
Server vs. Serverless Recording
Edge recording eliminates the server from the network. This type of edge recording decreases the bandwidth load and saves on hardware. While these benefits do result in several limitations to the capabilities on the camera. This application can also be challenging to implement with legacy devices.
Local recording can be used in conjunction with a video recorder to make the system more robust. A system may have a network recorder and also have edge recording capabilities to provide fault tolerance in the event of a network failure. In an event of an outage, the system would record to the cameras on the edge to avoid losing video completely.
Video Management System (VMS) Software on the Camera
The VMS software can be installed directly on compatible IP cameras. This edge installation saves bandwidth but also retains most of the benefits of a full-featured, sophisticated VMS. High resolution video is recorded directly to an SD card on the camera. See how Illustra Edge using exacqVision Edge VMS software pre-installed works.
Edge technology works best in environments where network bandwidth is constrained or space or budget limitations impact the use of physical recorders. In isolated environments where the network and WAN connectivity is unreliable such as power substations, mobile facilities, edge technology can provide a better way for video security.

SD Card Key Considerations
SD cards come in a variety of types and capabilities. To most effectively store your video directly on the edge remember these key considerations when purchasing an SD card:
- Quality matters: Select high endurance SD cards
- Speed matters: Recommend at least speed class 10 or UHS Speed Class 1 rated cards for full HD continuous recording
- Ensure SD cards are capable of functioning in the camera’s environment
- Leverage record-on-motion features of the VMS software or the camera to maximize the retention of useful video and the life of the SD card
