In these examples, the recording capacity of the DVR is fully allocated to normal recording, with no reserve capacity for increasing image size and/or FPS rate in response to a motion or alarm event (see next item). Since EverFocus DVRs have the capability to change recorded image size and FPS rate in response to events, it may be advisable to reserve some recording capacity for event response. For example:
2 cameras/4CIF/10FPS plus 5 cameras/2CIF/10FPS plus 9 cameras/CIF/5FPS: 2x4x10+5x2x10+9x1x5= 80+100+45 = 225 allocated with 255 in reserve
Quality: Select an image quality for recording. There are five different qualities available: Superior, High, Standard, Basic and Low. A higher image quality uses more HDD space.
Resolution: Select recording resolution based on video format. NTSC: 704x480 / 704x240 / 352x240
PAL: 704x576 / 704x288 / 352x288
Aud: Check this box to enable audio recording on the DVR.
Ins: Check the box to enable the current camera. To take full advantage of the DVR’s recording abilities, any unused cameras should have this option set to “disabled”.
