Just as with their view of the world, PTZ cameras seem to have gotten a piece of the action from every direction with each new wave in technology. Even back in the days when coax, power, and separate control lines had to be strung to their mounts, the usefulness of these gadgets was never questioned. High-definition video and improvements in optics have brought amazing clarity, while IP transmission and compression advances have enabled the higher data rates to be carried over a worldwide span. Now, Power-over-Ethernet (PoE) in its increasingly capable iterations has applied more juice for more features such as two-way audio, multiple event triggers, and IP notifications from and to anywhere. They have brought economical video production to churches, security to homes, and videoconferencing to businesses and schools. The models we’ve gathered here are typical of the usefulness in application and creativity in design that the world of PTZ cameras has enjoyed.
Designed by Acti Corporation with a 1/4in. interlaced scan CCD, two-way audio, and video motion detection, the ACM-8511 IP PTZ camera can provide video with lighting down to 0.07 lux at F1.8. Equipped with a 10X optical zoom and selectable MPEG-4 SP or MJPEG compression, the camera does 25/30fps at full D1 resolution and incorporates auto iris, auto focus, and a horizontal viewing angle from 48 degrees to 5 degrees with a signal to noise ratio of more than 44dB. It can pan from 20 to 90 degrees per second and tilt from 20 to 70 degrees per second. Class 3 PoE powers the ACM-8511 and features IP address filtering, HTTPS encryption, and password protected user levels, along with an alarm trigger and alarm response.
The P5544 PTZ dome network camera from Axis Communications is IP51-rated for protection against dust and dripping water and provides a 360 panoramic view with 18X optical zoom for monitoring large indoor areas. Equipped with Automatic Gatekeeper, the camera can detect motion in a predefined area and respond by moving to a preset position. With an optional multi-connector cable, the unit can provide two-way audio, audio detection, and input/output for external devices. A single camera uses two separate lenses. The zoom lens provides normal PTZ coverage, but the camera can also tilt straight down and shoot through a wide-angle converter for a 360-degree panorama. A mouse click on any spot in the panoramic view zooms the camera to that spot for a close-up.
Featuring Intelligent Video Analysis (IVA), the Bosch AutoDome 800 series HD PTZ camera can detect and analyze moving objects as well as loitering, multiple line crossing, and trajectories. It also supports Birds Eye View (BEV) people counting. Using 1080p resolution and sensitivity to below 1.0 lux, the camera supports 99 preset positions and two types of guard tours: preset and record/playback. Its pan/tilt speed ranges from a slow crawl at 0.1 degree per second up to 120 degrees per second, and the controls include Autoscaling (proportional zoom) and Autopivot. The video system uses H.264 encoding for streaming bandwidth efficiency, and there is support for a range of resolutions and frame rates. The ONVIF conformant system is interoperable with those of other manufacturers.
Canon designed the XU-80 HD remote control PTZ HD camera for indoor or outdoor use in generating a 16:9 aspect ratio using a CMOS HD 2.1 megapixel imaging sensor. The camera has a Canon 20x HD zoom lens and it incorporates several broadcast features, including a genlock input and HD-SDI output. These broaden the unit’s application range from surveillance to Internet streaming and venue IMAG. It can pan up to 60 degrees per second, and the housing is IP55 rated to be waterproof and dustproof. The XU-80W model adds a wiper and a servo operated neutral density (ND) filter. The black and white mode allows the system to shoot in near darkness, and dynamic range compensation makes better images in high-contrast environments. Users can select either 1080i or 720p HD output.
Longtime leader in document cameras and other imaging devices, Elmo designed the PTC-400C PTZ camera with 270-degree tilt and 250-degree pan flexibility with eight selectable speeds and a maximum pan/tilt speed of 100 degrees per second. This can be controlled either through an RS-485 daisy chain by setting the unit to one of 223 addresses or through the IR remote for up to nine cameras. The IR sensor on the front of the camera mount can detect control signals at 60 degrees to either side of center and between 10 degrees above and 30 degrees below the mounting location. The unit uses a 1/4in. color CCD to generate 470 TV line resolution with a 12X optical zoom at a minimum light level of 1 lux. Features include backlight compensation, auto iris, auto/manual focus, area masking, and image flip. Users can adjust AGC gain, hue, detail compensation, and high-speed shutter.

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.

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.
