For indoor surveillance applications under a wide range of lighting conditions, Acti Corp. offers the ACM-8211 1.3-megapixel IP PTZ camera featuring 1/3in. Micron progressive scan CMOS, day and night function with a mechanical IR cut filter, selectable MPEG-4 SP/M-JPEG compression, and multistream capability with variable frame rate in the same compression. The camera supports twoway audio and provides hardware three-window motion detection and digital input/output. Power may be supplied by an external 12VDC source or applied via PoE IEEE 802.3af. In low light conditions less than 4 lux, color mode is automatically switched to black and white. The ACM-8211 provides a number of preset, automatic, and manual white balance settings; pan speed range of 20 degrees per second to 120 degrees per second; and a tilt speed range of 15 degrees per second to 70 degrees per second.

The Q6034-E day/night camera from Axis Communications combines an 18X optical and 12X digital zoom with autofocus and a 16:9 aspect ratio along with SMPTE 269M-compliant 1280×720 resolution. The model’s support for high power over Ethernet (IEEE 802.3at) allows it to use a single cable for power, video, and PTZ control. The Axis Arctic Temperature Control allows the camera to be used at temperatures down to -40 degrees Fahrenheit, and it has a built-in SD/SDHC card slot for local storage. The camera includes the Active Gatekeeper function to automatically move the shot to a preset position when motion is detected in a predefined area and the subject on video is tracked. The video output is H.264 motion JPEG from a 1/3in. progressive scan 1.3-megapixel CCD.

Canon USA BU-51H

Canon USA designed the BU-51H 3CCD camera system for a wide range of indoor applications including surveillance, stage IMAG, videoconferencing, studio, and house of worship. Using a 20X zoom lens with 2X digital extender, the unit has adjustable night mode shutter speed, a builtin microphone, pan/tilt/zoom/focus position information output, and multiple video output formats. The outputs include uncompressed SD/HD SDI and an SD composite signal that can be simultaneously output and used for monitoring. Genlock is also available for video synchronization through a BNC connection. Focus may be either auto or manual, and gain is adjustable from 0dB to 36dB in six steps. The camera also features optical-shift image stabilization; auto, manual, and night shooting modes; and both auto and manual iris operation. Dustproof and waterproof efficiency is rated at 45IP.

For indoor monitoring and surveillance, Compro Technology markets the IP750P with the capability for continuous movement in 340-degree pan and 100-degree tilt. The camera has a 12X auto focus optical zoom, a built-in IR function and IR LEDs, 1280×1024 HD resolution, a built-in microphone, and two-way audio. It can output video in H.264, M-JPEG, and MPEG-4 with dual streams support along with micro SD/SDHC local storage for video and snapshots. Additional features include motion detection and 30 shot presets with one preset sequence. The IR LEDs turn on automatically under low light and turn off when light level returns to normal. With the optional WL 150 USB module, the unit can operate via 802.11b/g/n wireless LAN.

The ElmoPTC-400C 1/4in. CCD camera produces 360 vertical lines of resolution with internal synchronization and features a 12X optical and 16X digital zoom, maximum 100-degree-per-second pan/ tilt speed (eight auto/manual speeds), day/night function, image flip, two alarm inputs, 16 shot presets, and remote control via IR and RS-485. With the remote controller, up to nine cameras may be simultaneously operated, and through an RS-485 daisy-chain connection, up to 223 cameras may be used. The unit runs on 12VDC and uses 12W power. Picture adjustments include hue, AGC gain, detail compensation, and high-speed shutter with auto/ manual focus and white balance. The camera also has a power save mode, and each preset shot can be labeled with up to 10 characters.


Designed to be flexible in maintenance as well as in operation, the VN-685U PTZ network dome camera from JVC can be swapped out with another one without removing the base. This preserves all presets and other programming and applies it to the replacement camera. Equipped with a 27X optical and 34X digital zoom, the unit can output MPEG-4 and M-JPEG VGA full-frame dual-stream video and has several AGC modes to operate in a wide range of lighting conditions. It has 100 presets, motion detection with intelligent auto tracking, and privacy mask. The camera can silently pan at speeds from 0.04 degrees per second to 400 degrees per second and position with an accuracy of 0.03 degrees. With optional mounting gear, the camera can be ceiling-pole mounted, wall-mounted, or flush-mounted into the ceiling. It uses 24VDC power over Ethernet and two alarm inputs and outputs.

Panasonic i-Pro SmartHD WV-SC385

Using Panasonic’s UniPhier LSI chip, the i-Pro SmartHD WV-SC385 provides 720p video at up to 30fps and outputs multiple H.264 and JPEG video streams. The camera entered the market last November, and it has a new 1.3-megapixel MOS image sensor for high sensitivity using less power. For flexible network integration, it is Open Network Video Interface (ONVIF) compliant. Offering up to 64 preset positions, the unit also has an auto flip function that enables panning from 0 degrees to 360 degrees, and this is combined with auto tracking using four detection areas, 15 sensitivity steps, and 10 steps of detection size. When used with Panasonic’s WV-CU950 universal system controller, the camera moves with 256 speeds.

Pelco Spectra HD

With wide dynamic range capability, the IP-based Spectra HD from Pelco can compensate for shots in which there is a high contrast between background and foreground illumination, and the unit features automatic cut filter removal for day/night operation. Digital Slow Shutter (DSS) enhances camera sensitivity to improve low-light performance. Additional features include image stabilization and motion detection. An integrated scheduler allows preprogramming of alarms, preset shots, and relay contact closures. Pan speeds range from a very slow 0.1 degrees per second up to 400 degrees per second, and the optional Remote Monitor Kit connects to the RJ-45 port to allow video viewing, control, setup, and system upgrades from the controller. Transmission on single-mode or multimode fiber can be done with the attachment of PelcoFiber modules. The system can simultaneously output streams in dual MPEG-4 at 30fps and scalable M-JPEG.
