There is a growing trend in IP video surveillance market of having cameras with built-in local storage that can host the video clips and snapshots captured by the camera.
While the traditional analog camera systems had to rely on DVR to convert the analog video to digital and compress it before saving, the IP cameras directly produce compressed digital video which gives the possibility to save the digital video right inside the camera itself or by using NVR over the IP network.
When speaking about using camera’s local storage in real surveillance applications, one would have many questions: What is the role of camera’s local storage in the surveillance solution architecture? What are the advantages of local storage? Is it safe to rely on camera’s local storage? What are the limitations of local storage? How to use ACTi cameras’ local storage?
This article gives the answers to all these questions.
