The VN-H257VPU advanced full HD network outdoor dome camera from JVC is capable of producing rich color images in light as low as 0.5 lux (50-percent video level, without slow shutter) and generating up to 1920x1080 resolution. The system supports ONVIF and PSIA standard protocols for cross-vendor interoperability. It is compatible with H.264, Motion JPEG, and MPEG4. It runs at a 30fps frame rate and can be powered by 24VAC or PoE (48VDC). Other features include audio and alarm in/out, vandal protection, motion detection and privacy mask, active tamper detection, SD card recording, and an integrated lens. The VN-H257VPU can be fitted with a recessed ceiling mount, wall mount, or hanging pendant mount. Embedded Clear Logic Video Intelligence (C.L.V.I.) image processing provides wide dynamic performance, back light compensation, edge enhancement, and anti-fog capabilities.
Capable of producing 720p images at up to 30fps, the Panasonic WV-SC385 Super Dynamic HD dome network camera runs on PoE IEEE 802.3af while providing color images down to 0.5 lux and monochrome to .06 lux. Panasonic equipped the unit with a 36X optical zoom and 1.3 megapixel double speed MOS Sensor in an ONVIF-compliant system. Multiple H.264 and JPEG streams allow simultaneous realtime monitoring and high-resolution recording. H.264 and MPEG-4 are selectable for system migration, and the camera includes privacy masking for up to eight separate areas. Alarm functions include a terminal, browser indication, and email notification along with JPEG-image-compression switching to produce higher resolution as an alarm response. There is also a SDHC/SD memory card slot for manual recording, alarm recording, or backup upon network failure.
Intended for security monitoring and surveillance, the Pelco Spectra IV IP H.264 Series network dome system allows simultaneous IP and analog monitoring and control while providing H.264, MPEG-4, and MJPEG compression. The series includes three autofocus high-resolution integrated camera/optics packages with auto-tracking, multilevel password protection, horizontal zone and window blanking for up to eight zones, and the 35X models have a sensitivity figure down to 0.00015 lux in PAL. The ONVIF v1.02-compliant systems provide bi-directional full duplex audio, web browser control and viewing for up to 16 cameras per network, 512MB RAM, password protection, 256 presets, and seven alarm inputs. Up to eight movement patterns may be programmed, and the scan speed can be varied from 1 to 40 degrees per second.
The POL-331PW wireless indoor/outdoor PTZ camera from Polaris USA has a built-in heater and fan for operation in extreme temperatures and it features dual codec H.264/MJPEG encoding, 704x480 resolution, client CMS (Central Management Software) or IE browser-based control, a 33x optical zoom, and a polycarbonate dome cover. The system supports a wireless 802.11 b/g connection, two-way audio transmission and alarm I/O. The 3.3-99mm auto focus zoom lens can be positioned in any of 128 preset positions and produce images with lighting down to 0.02 lux. The included CMS software has the ability to stream the video of all the cameras directly to a computer hard drive incorporating many network video recorder functions. The unit runs on a local 24VDC power supply.
Samsung designed the SCP-2370RH to capture details very clearly at night for up to 328ft. using its 37X optical zoom and built-in IR LEDs along with the embedded Samsung W-5 chipset. It offers SSNRIII (Samsung Super Noise Reduction, 3rd generation), a heater, and a fan incorporated into the IP66-rated housing. The imaging system provides 600 TV lines resolution in color and 700 in black and white with illumination down to 0.2 lux (color), 0.02 (B/W). Controllable on RS-485, it includes motion detection and runs on a local 24VDC power supply.
Fitted with a 20X optical zoom lens, the EVI-H100V uses a DVI-I connector to send both digital and analog systems a 1080p/30 video signal. Sony included a 1/2.8-type Exmor CMOS sensor for performance down to 0.5 lux in high sensitivity mode. As is typical with Sony PTZ cameras, units can be daisy chained for VISCA RS-232 control by setting the address on each housing or run on RS-422 straight to a computer. The camera is locally powered on 12VDC and can be locally controlled with the handheld IR Remote Commander. Features include image flip, automatic and manual exposure control with priority control for shutter or iris, six presets, up to 100-degree-per-second pan, and 90-degree-per-second tilt speed. The EVI-H100S is a similar model substituting composite and HD-SDI video outputs.
