Specifications
| Camera registration monitoring | |
|---|---|
| No. of registerable camera units |
Up to 64 camera units. Note that the actual number of registerable camera units varies depending on the performance of the PC used. |
| Camera image view | Sequential display, Up to 16 multi-camera display, full screen display, layout change |
| Image display size | Automatically adjusted to match the camera layout. |
| Camera setup | Each camera can be set up individually (camera name,resolution, image quality setting, recording format, timer setting, etc.) |
| Selected camera image display |
Automatically adjusted to match the camera layout. |
| Image zoom in/out | None (Automatically adjusted to match the camera layout.) |
| Camera control | Control of basic camera functions (pan/tilt/zoom, brightness,resolution, image quality, sound level). |
| Preset | Preset functions set in cameras can be used |
| Recording | |
| Recording file format |
Original file format: Images and voices are recorded continuously in a moving image file. |
| Recording media | Hard disk, network dirive*1 |
| Recording resolution | 5 sizes (160 x 120 to 1280 x 1024)*2 |
| Image quality (JPEG only) |
Favor clarity, standard, favor motions |
| Recording interval | Not specified (based on camera's image update interval), specified: 5 images/second to 1 image/hour Recording interval designation and sound recording can be done simultaneously. |
| No. of camera units for simultaneous recording |
Dependent on camera type and performance of PC. See the hardware specifications below. |
| Recording capacity limit function |
Maximum recording capacity value can be set for individual camera units (whether to save new data by overwriting or to stop recording when the set capacity is reached can be selected). In addition to a capacity limit for each camera, there is also a capacity limit for the entire storage media. |
| Motion detection recording (JPEG only) |
The unit can be set to activate recording when motion is detected (sensitivity and threshold value can be adjusted) or to record for a certain time length before and after motion detection.*3 Motion detection can be disabled in specified areas. Motion detection can be confirmed on-screen. |
| Timer recording | Programming of start and stop schedules based on day of week and time. Key word can also be set for recording. (10 schedules can be registered per camera). |
| Alerm recording (JPEG only) |
Recording is triggered by the reaction of a sensor mounted to the camera. A certain time length before and after the sensor reaction can also be recorded. |
| Disk capacity limit function |
Monitors the free space on the specified recording disk, and stops recording when the free space becomes smaller than the set value. |
| Image operation | |
| Continuous play back | Playback of images with voices, playback of image files. Playback speed can be varied. Playback in reverse is possible. Simultaneous playback of images from multiple cameras is also possible. |
| Recorded image view | A list of recorded image files, or a graphical list can also be displayed. |
| Operation of recorded images | Recorded images can be copied or deleted. |
| Format conversion | All or part of the recorded images can be converted to MPEG-1, MPEG-4, or JPEG format files, or only the audio portion can be converted to WAV files. |
| Image search | |
| Recorded image search function |
Search recorded images in 1-day units using the recording time,
or using a key word set before recording. Searching can also be done for particular, desired folders. |
*1-1 Folders on the network allotted to the drive can be specified for saving data.
*1-2 When a network drive is specified as a folder for saving data, the amount of data flowing over the network increases. This may remarkably degrade the operating performance for watching or recording camera images, watching previously recorded images, etc., and may also result in errors.It is recommended that a folder on a local disk be specified for saving data.
*2 MPEG-4 camera using an MPEG-4 connection: 640 x 480, 320 x 240, 192 x 144 MPEG-4 camera using a JPEG connection: 1280 x 1024, 640 x 480, 320 x 240, 192 x 144
*3 The detection level varies depending on the camera resolution, image quality setting, subject conditions, network conditions, etc.
System Requirements for your PC
| Item | Description |
|---|---|
| OS | Windows®XP(32bit)/ Vista(32bit) |
| Web browser | Internet Explorer 6.0 or later |
| File system | NTFS (NT File System) recommended |
| Hardware specifications | |
| Recording condition |
· When 10 network camera units are connected CPU: Intel® Pentium® 4 3GHz or greater, or equivalent compatible processor, RAM: 1024 MB or more* · When 2 network camera units are connected CPU: Intel® Pentium® 4 2.6GHz or greater, or equivalent compatible processor, RAM: 512 MB or more* |
| Voice | Audio output function (including speaker or headphone) |
*This specification is required for using all network cameras to simultaneously record at a resolution of 320 x 240 in standard image quality, while monitoring with all registered cameras at a frame rate of 2 fps.
Still and motion image data size
JPEG Data size for 1 image frame (image only), Data format: JPEG
| resolution (dot) | size(KB): favor clarity |
size(KB): standard |
size(KB): favor motion |
|---|---|---|---|
| 1280 x 1024 | approx.100 | approx.77 | approx.60 |
| 640 x 480 | approx.50 | approx.35 | approx.27 |
| 320 x 240 | approx.25 | approx.16 | approx.10 |
| 194 x 144 | approx.10 | approx.7 | approx.5 |
| 160 x 120 | approx.7 | approx.5 | approx.3 |
The approximate recording capacity is calculated by using the following formula:
Size (KB) x Frame rate (images/sec) x Recording time (sec)
Example
- The calculation for a 1-hour recording of 640 x 480 resolution images at a frame rate of 5 images/sec in Favor Clarity mode is as follows:
50 KB x 5 images/sec x 3,600 sec (1 hour) = 900,000 KB ≒ 879 MB - In case of images with voices, 4 KB is added per each second:
900,000 KB + 4 KB x 3,600 sec = 914,400 KB ≒ 893 MB
MPEG-4 Data size for 1 second of motion images (images only), Data format: MPEG-4
| resolution (dot) | MPEG-4 bit rate* |
|---|---|
| 640 x 480 | 768kbps |
| 320 x 240 | 384kbps |
| 194 x 144 | 128kbps |
* MPEG-4 bit rate: This depends on the value set at the camera for MPEG-4 bit rate for image distribution.
The approximate recording capacity is calculated by using the following formula:
MPEG-4 bit rate (Kbps)/8 bits x time (sec).
Example
- The calculation for 640 x 480 resolution images at an MPEG-4 bit rate of 768 Kbps is as follows:
768 Kbps/8 bits x 3,600 seconds (1 hour) = 345,600 KB ≒ 337.5 MB - In case of images with voices, 4 KB is added per each second:
345,600 KB + 4 KB x 3,600 sec = 360,000 KB ≒ 352MB
