WV-NP304, 1/3" CCD, 1280 x 960, 30 fps, 1.5 lux Fast Ethernet, PoE Day/Night Network Camera featuring a 1.3 Megapixel CCD for superior image
Equipped with the 1/3 inch 1.3 megapixel progressive scan CCD and the proprietary DSP, The WV-NF302/WV-NP304 provide superior image of 1,280 x 960 pixels, enhancing their identification capability. The progressive scan CCD ensures clear images with less motion blur and no tearing even when the subject is moving. ABS (Adaptive Black Stretch) increases visibility of subjects in dark areas without degrading image quality in bright areas by analyzing the “illumination map/signal level distribution” and adjusting gamma correction for each area separately. A megapixel camera requires a high definition lens whose depth of focus tends to be so shallow that precise focus adjustment is required. Focus Assist function uses an on-screen display to indicate the best focus position making accurate focus adjustment simpler. With a minimum illumination of 0.9 lux in B/W mode 1.5 lux in color (with clear dome for NF302), a clear surveillance image can be captured even in poorly lit, dim conditions.

Megapixel
High Image quality is vital to all surveillance cameras. The i-Pro megapixel network cameras are equipped with a progressive scan 1.3 million pixels CCD and proprietary DSP that delivers outstanding image quality. The image is so detailed that it allows operators to identify subjects on a whole new level when compared to existing analog TV standard systems. Alternatively it can capture an area four times larger while maintaining the same image quality of conventional cameras.

Progressive Video Output
Interlaced video produced by an interline transfer CCD has motion blur and tearing problems. This is caused by the timing difference between odd fields and even fields, which gives the image a jagged appearance. This has been a particular problem with conventional surveillance cameras. The i-Pro network cameras provide progressive video output by using a progressive scan CCD or Motion Adaptive Interlace-Progressive conversion,* ensuring clear images with less motion blur and no tearing even when the subject is moving.

ABS (Adaptive Black Stretch)
ABS (Adaptive Black Stretch) increases visibility of subjects in dark areas without degrading image quality in bright areas by analyzing the “illumination map/signal level distribution” and adjusting gamma correction for each area separately.

Focus Assist
A megapixel camera requires a high definition lens whose depth of focus tends to be so shallow that precise focus adjustment is required. Focus Assist function uses an on-screen display to indicate the best focus position making accurate focus adjustment simpler.

Real Time Monitoring
The i-Pro network cameras can transmit 30 images/second real time video at up to VGA (640 x 480) image size in both JPEG and MPEG-4 mode. They can also simultaneously transmit high frame rate MPEG-4 and high quality JPEG images, making real time monitoring possible while recording high-resolution images.

High Sensitivity
All i-Pro network cameras combine high sensitivity design and electronic sensitivity enhancement functions, enabling them to capture color images even when the lighting is dim. If the situation is too dark, the Day/Night Switching feature* automatically switches the camera from color to B/W.
With a minimum illumination of 0.9 lux in B/W mode 1.5 lux in color, a clear surveillance image can be captured even in poorly lit, dim conditions.

MPEG-4 and JPEG Dual Streaming
The WV-NF302/WV-NP304 allows real time monitoring in MPEG-4 (VGA : Max. 30 ips) while simultaneously shooting high-resolution JPEG (1,280 x 960: Max. 5 ips) images

PoE (Power over Ethernet)
With IEEE802.3af PoE (Power over Ethernet), both power and image data can be transmitted through a single Ethernet cable. By eliminating the need for power cables and supplies when installing cameras or changing layouts, installation and maintenance costs are reduced.

Easy IP Set-up
When the i-Pro network cameras are connected to the i-Pro Network Disk Recorders, their IP addresses can easily be obtained through the Easy IP Set-up features. By reducing the time and labor required for network set-up, Easy IP Set-up lowers installation and maintenance costs.

Flexible Alarm Handling
Various alarm sources including Terminal input, VMD and Panasonic alarm command can trigger actions including SD memory recording, FTP image transfer, E-mail notification, Indication on browser, Alarm terminal output and Panasonic protocol output. The image compression ratio can also be changed in response to an alarm, so that higher quality image can be provided as necessary. With these features, flexible alarm handling can be designed according to the application requirement.

Prioritized stream control
With prioritized stream control, one of the video streams can be prioritized when multiple recorders or client PCs are accessing the camera so that a recorder or a client PC can maintain the frame rate.

User management
User/Host authentication feature includes 3 user levels, Administrator/Camera control/ Live only for sophisticated user management, enabling to block operations from unregistered users and hosts.

Privacy zone
Privacy zone masking for up to eight locations is also available.

SD Memory Backup
Network problems can be an issue with all IP network systems. This is why the i-Pro network cameras are equipped with an SD Memory Card slot, so that when the network experiences a problem, during the data transfer to a FTP server or an i-Pro network recorder, images can automatically be backed up. This prevents image loss and makes it possible to playback and check images captured while the network is down.

Audio Features
Full duplex bi-directional audio allows interactive communication between camera site and monitoring site.
