"A digital video recorder (DVR) from Dahua Technology, Sometimes referred to by the merchandising term personal video recorder (PVR),
is a consumer electronics device or application software that records video in a digital format to a disk drive, USB flash drive, SD memory
card or other local or networked mass storage device. The term includes set-top boxes (STB) with direct to disk recording facility,
portable media players (PMP) with recording, recorders (PMR) as camcorders that record onto Secure Digital memory cards and software
for personal computers which enables video capture and playback to and from a hard disk drive.

A network video recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory
card or other mass storage device. An NVR contains no dedicated video capture hardware. However, the software is typically run on a
dedicated device, usually with an embedded operating system. Network video recorders are distinct from digital video recorders as their
input is from a network rather than a direct connection to a video capture card or tuner. Video on a DVR is encoded and processed at the
DVR, while video on an NVR is encoded and processed at the camera, then streamed to the NVR for storage or remote viewing.[citation
needed] NVR is used in IP video surveillance systems. Hybrid NVR/DVR security systems exist which incorporate functions of both
NVR and DVR; these are considered a form of NVR.[citation needed] NVR home security systems are wireless, tend to be easy to set up,
can be accessed through a web browser, and allow the user to be notified by email if an alarm is triggered."
