Terms Used in these Operating Instructions
HDD
Refers to a hard disk drive (mass storage medium). The unit records camera pictures on a hard disk rather than on video tape.
Recording rate (ips, I-Frame)
Refers to the unit that determines the smootheness with which the recorded images are played back. "ips" is used to express the number of frames recorded per second. The higher the number, the smoother the movement, but the available recording time becomes shorter.
Resolution
Resolution refers to the degree of fineness and quality of the camera pictures recorded by this unit. This unit dis- plays the resolution in number of dots. For example, if the number of horizontal dots is 720 and the number of verti- cal dots is 480, the display reads 720 x 480.
M-JPEG
A video codec that compresses video fields from the camera into independent JPEG images sequentially by query from the unit.
Network load will be reduced comparing with the method that obtains JPEG images independently from the camera. However, the transmission rate will fluctuate depending on the state of the camera.
Some cameras phrase this video codec as just "JPEG".
Manual recording
Function for starting and stopping recording manually by clicking the recording button or recording stop button.
Schedule recording
Function for starting and stopping recording automatically at a preset time.
Event recording
Function for starting recording automatically when an event occurs.
Event recordings are divided into pre recordings (pictures before the event occurs) and post recordings (pictures after the event occurs).
Emergency recording
Function for performing priority recording in emergency situations, etc. through an external switch connected to the unit.
SD memory recording/SD memory data
Function featured in some Panasonic’s cameras that saves images on the SD memory card on the camera when communication with the camera failed in the period set for the schedule recording of this unit. Images saved by the SD memory recording are described as "SD memory data" on these operating instructions. The recording time of SD memory data will be displayed based on the clock of the camera.
