Features
Remote Video Monitoring / Control Over Networks
The SNC-Z20P is equipped with a 100Base-TX/10Base-T (RJ-45) interface and a built-in web server. This allows a PC running a standard web browser to monitor its live images and control the unit without the need for additional software or plug-ins. Up to 50 users can simultaneously access, monitor, and control the images of a single SNC-Z20P camera.
High Picture Quality and High Zoom Ratio
The SNC-Z20P incorporates a 1/4 type CCD with Exwave HAD technology, offering high resolution images with excellent sensitivity and achieves a horizontal resolution of 460 TV lines.
Built-in auto-focus 18x optical zoom lens
The built-in auto-focus 18x optical zoom lens enables the user to obtain clear images even when enlarged. A maximum 216x zoom ratio is available when the optical zoom and 12x digital zoom are used together. To cover a wide angle of view, an optional VCL-0637H Wide Conversion Lens can be attached.
High Frame Rate
The SNC-Z20P offers a maximum frame rate of 25 fps, allowing clear and smooth frame accurate images to be viewed. The frame rate can be set to a fixed or variable frame rate, which is automatically adjusted according to the available bandwidth.
PC Card Slot
A built-in PC card slot on the front panel of the SNC-Z20P enables you to increase the SNC-Z20P storage capacity for pre/post-alarm recording by adding either a flash ATA memory card or an ATA hard disk drive (HDD) card. IC recording media such as a Memory Stick™ media card with a Memory Stick/PC card adaptor can also be used.
Wireless Network Operation
The SNC-Z20P is compatible with an IEEE 802.11b -compliant wireless PC card allowing wireless network operation.
Day / Night Function
The SNC-Z20P offers a Day / Night function to provide optimised sensitivity in both day and night shooting scenarios. As the scene illumination reduces and the image darkens, the infrared filter is automatically removed and the camera switches to B/W mode, achieving a minimum illumination of 0.01 lx.
Power-over-Ethernet Operation
The SNC-Z20P offers a choice of three different power supplies. AC 24 V or DC 12 V can be supplied through the standard power terminal. Power can also be supplied via an Ethernet CAT5 cable from an IEEE 802.3af - compliant power supply system allowing single cable operation. AC 24 V, DC 12 V, or PoE (Power over Ethernet) is automatically selected according to the power supplied.
Pre- / Post-Alarm Image Storage
With the internal 8 MB buffer or a memory card installed in the PC card slot, the SNC-Z20P can store hundreds of pre-alarm and post-alarm still images at an alarm trigger received either from the activity-detection sensor or the alarm input.
Image Transfer using FTP / SMTP
The pre- / post-alarm images stored at the time of an alarm event can be transferred to an FTP server, and the still image can also be sent to a specified e-mail address as a JPEG attachment, enabling the user to see what happened before and after an alarm occurred.
Compatible with IMZ-RS Series Monitoring software (RealShot Manager)
By installing the optional IMZ-RS Series Monitoring Software, up to 32 cameras can be simultaneously monitored and controlled from a single PC. The images from these cameras can also be recorded to the PC’s hard drive.
Mobile monitoring through PDA
Images can be viewed from a personal digital assistant (PDA) such as a Sony Clie or Pocket PC.
IP Filtering (security)
Using the IP-filtering feature, access to the SNC-Z20P can be restricted to one or more groups of selected users. Up to ten different groups can be established by defining an IP-address range for each group. Setting these groups restricts access to the camera to the defined IP-address range, while denying access to all other addresses.
Password Protection
User names and passwords can be assigned to allow four levels of access. Generally, the administrator has complete access/control of the camera, while the other three levels can be set to limit user privileges to functions such as zoom control, viewing, trigger control, etc.
Selectable Image Quality and Size
The SNC-Z20P gives you the flexibility to select image quality and image size according to your network bandwidth. Employing the industry standard JPEG-compression format, the SNC-Z20P has a selectable compression ratio between 1/5 and 1/60. Also, the image size can be selected from four modes: 736 x 544, 640 x 480, 320 x 240, and 160 x 120.
Slow Shutter
In addition, the slow shutter mode provides a remarkable enhancement in sensitivity by allowing the charge accumulation period of the CCD to be extended to a maximum of 1 second.
Backlight Compensation (BLC)
The Backlight Compensation (BLC) function helps to overcome strong backlighting effects, which often cause the subject of the picture to be cast into shadow. The picture brightness can be adjusted automatically to allow for changes in lighting conditions, optimising the image intelligibility under very adverse lighting conditions.
Alarm Function Activity Detection / Alarm Trigger
The SNC-Z20P is equipped with a built-in activity detection sensor that can be set to trigger an alarm or a switch through alarm-output ports. If a change in luminance level is detected in the field of view, an alarm is automatically triggered. In addition, the camera comes with an alarm input port to receive a trigger from an external sensor.
Analogue Composite Video Output
The SNC-Z20P can output an analogue composite video signal from a BNC connector located on its rear panel. This allows recording or monitoring of the local image by connecting analogue video equipment. Images from the camera can be electrically reversed upside down – allowing the camera to be installed in a variety of locations and positions.
RS-232C Interface (Transparency Function or VISCA™ Protocol)
The SNC-Z20P has a transparency function available via the RS-232C interface. This allows external equipment connected to the RS-232C port of the camera to be controlled from a PC over the network. Also, the SNC-Z20P can be controlled with the VISCA protocol from an external control device, allowing local control of zoom and camera settings.

Benefits
Access your video from anywhere at any time
The SNC-Z20P simply connects to your TCP/IP network allowing you to access the video from anywhere on the network.
Excellent performance under low light conditions
Sony ExwaveHAD technology allows the SNC-RZ20P to give outstanding performance in monitoring and surveillance applications dealing with very low light conditions.
Easy installation
Supporting all standard network protocols, installing this camera is an easy task by simply connecting the Ethernet cable to any TCP/IP Network. The supplied set-up software makes it possible to start monitoring within minutes after you installed the camera. Installation can be made even easier using a single cable for both power and data transmission.
Wireless transmission
More installation flexibility is provided using an optional wireless PC card for wireless network operation.
Capturing all picture detail required
The image quality is extremely high, making it the ideal camera for effective surveillance and monitoring providing you all the detail required even when enlarged using its 18x optical zoom lens.
No bandwidth consumption thanks to local picture storage
The storage capacity of the SNC-Z20P can be increased by adding memory allowing you to store hundreds of images on the unit without having to consume bandwidth on the network.
No separate monitoring software required
Using a standard web browser you can easily access the SNC-Z20P thanks to its built-in home page. This graphical user interface is designed for easy control and quick access to all functions.
Limit camera access to relevant persons only
Security management allows you to limit the access to those who have permission only by password protection and IP-filtering.
Unattended operation
The built-in activity detection function enables you to keep easily track of activity on site while not actively monitoring. The camera can be set to automatically store or send pictures when activity is being triggered.
