Operating instructions

SD Advanced

Unset/Set/Override Normal Shows the recording prole used by the camera if no Timed

Schedules are applied and the camera is operating under Normal

(non Event) conditions. Refer to ‘Schedule’ for further information.

Unset/Set/Override Event Shows the recording quality that will be used by the camera

during an Alarm or Event. Note that Set and Override schedules

will be used only when Timed Schedules are applied. Refer to

‘Schedule’ for further information.

Note: When Turbo mode is selected, there will be only ONE congurable Record Prole

across ALL cameras. The unit then matches the live transmission rate to the congured

record rate. This enables a ‘doubling’ of performance. Only the ‘Low’ and ‘Medium’

Live Transmission proles are available for conguration (Network Settings->Live

Transmissions). Low and Medium transmission settings are congurable to allow video

streaming over low bandwith IP connections and are limited to CIF for this purpose.

Note: Unset, Set and Override modes can be given more recognisable titles i.e. Day, Night,

Weekend via the Schedule menu (Record Settings->Schedule).

Comp Select image compression format (MPEG, JPEG, H264).

Res Select image resolution format (QCIF, CIF, 2CIF or 4CIF).

Rate_kbps If MPEG4 is selected, the gure entered here will be the bit rate

allocated. A higher bit rate will provide better quality. MPEG bit

rates can be entered within the range of 45-2500K bits/second.

IMPORTANT: The bit rate allocation here will be limited to a maximum rate (limit dependant on

model). For 8 and 16 channel units, the limit is 2048 per camera. For 32 channel

units, the limit is 1024 per camera.

Size If JPEG is selected, the gure entered here will be the size of the

JPEG transmitted (in Kbytes). JPEG le sizes can be congured

within the range of 5-45Kbytes.

PPS Select the number of pictures recorded per second.

GOP If using MPEG4 recording, select the number of images

recorded within a GOP (Group of Pictures). A GOP consists of

an I-Frame (keyframe) and following P frames.

Note: The GOP is also the rewind interval and stop interval for MPEG recording playback.

Note: An MPEG I-frame is considerably larger than a P-frame. Therefore the lower the GOP

ratio, the higher the disk space required to store recorded images.
