Toshiba IK-WD12A

Toshiba IK-WD12A

The IK-WD12A indoor IP mini dome camera from Toshiba uses a 1/3 2in. image sensor to provide a 2-megapixel maximum 1600x1200 resolution through a varifocal lens with 3X optical and 4X digital zoom. With quad streaming motion JPEG and MPEG-4 image compression, the system delivers a wide range of image sizes and frame rates, and adds a true day/night IR cut filter along with motion detection and a privacy mask using up to five windows. The unit supports a variety of protocols, supports both IPv4 and IPv6, and includes an SD card slot for video recording at the camera. On the audio side, it features a built-in microphone and two-way audio with a mic input and line output.

With the capability to send high-quality video signals over secure wireless connections, the TRENDnet TV-IP422W has night visibility up to 16ft. along with day/ night recording operation, motion detection, and two-way audio. The software allows email alerts and scheduled recording of MPEG-4 and M-JPEG from 1fps to 30fps with five compression ratio settings. The camera’s advanced encryption modes include WEP, WPA-PSK, and WPA2-PSK. A 3X digital zoom teamed with automatic exposure control, white balance and gain control, and a maximum 640x480 video resolution provide good picture quality and flexible configuration. Along with adjustable brightness, contrast, and saturation, there are eight position presets and a wide range of networking protocols are supported.

Vaddio ClearView HD-20

The new 3.27-megapixel ClearView HD-20 camera from Vaddio features 20X optical hyper-zoom lens and imaging sensor technology comparable to a 3-chip camera. The multi-element motorized zoom lens and new slip-clutch robotics system enhance performance with smooth pan/ tilt operation for accurate camera movement and control. The HD-20 is built around a 6.49mm diagonal (1/3-type) Sony Exmor sensor, which adopts the Column-Parallel A/D Conversion technique. With a lux rating of 1.6, the HD-20 also achieves improved picture quality in very low light environments. Control runs via VISCA command protocol or the IR remote that is supplied. The camera outputs HD video in both analog component (YPbPr) and HDMI formats in resolutions of 1080p, 1080i, and 720p. There are optional video output cards available.

Vivotek PZ7111/PZ7112

Vivotek PZ7111/PZ7112

Available in two variants, the PZ7111/PZ7112 from Vivotek offers built-in WLAN connectivity with the PZ7112 and IEEE 802.3af PoE-compliant operation with the PZ7111. Both models offer a 10X optical zoom lens, 10X digital zoom, realtime M-JPEG and MPEG-4 compression in dual streams, 3GPP mobile surveillance, HTTPS-encrypted data transmission, a digital I/O function for external sensors and triggering external alarms, and two-way audio using SIP protocol. In low-light mode, the camera can produce images in light levels down to 0.05 lux. Image size, quality, and bit rates are adjustable, and the unit features time stamp and text caption overlay. Additional image adjustments include saturation, sharpness, white balance, and flip/mirror functions.
