Pan Tilt Zoom - PTZ Camera

Pan, Tilt Zoom (PTZ) Cameras, often referred to as dome cameras can be moved 360 degrees and zoom in and out by using a PTZ joystick which can be plugged into a PC based or stand alone dvr. This type of surveillance camera is often found at commercial locations and allow the user to follow a subject or to zoom in on an area of interest.

The ptz cameras can zoom in and out, making it very versatile. These domes can be operated using a ptz controller. Using the keyboard, PTZ domes can be programmed to patrol an area automatically or can utilize alarm triggers to induce movement by the camera. For example, PTZ security cameras can be programmed to patrol a parking lot every 5 minutes. Additionally, triggers such as motion detection can alert the camera to reposition itself.

The total zoom capability of PTZ security cameras is a combination of optical zoom & digital zoom. Digital zoom simply magnifies a picture using the on board software while optical zoom uses the lens itself to zoom in. The picture from the optical zoom of a cameras is always much superior to digital zoom. The total zoom of a camera can be calculated by multiplying the digital zoom by the optical zoom. For example a ptz camera with a rating of 100x is actually 10x actual lens zoom and 10x electronic zoom.

One great thing about PTZ domes is they are often smoked or otherwise obscured, making it hard for people to tell if they are being watched. PTZ domes come in a variety of configurations like weatherproof and day/night. Day/night capability means the security cameras are color by day and black and white at night. Then some ptz cameras are low resolution to some that are very high resolution. After that some ptz dome cameras can rotate  360 degrees while others cannot. A lot of the new ptz cameras have a WDR function built into them, which allows the camera to see 2 different light conditions at the same time.

They can be mounted anywhere using a variety of dome mounts, such as pendant and recessed mounts. A pendant mount allows the camera to hang from the mount arm as a pendant does on a necklace. A recessed mount hides the entire camera except for the dome. Cameras using these mounts usually are mounted in drop or tile ceilings.

PTZ dome security cameras have several advantages over traditional security cameras. PTZ Domes can efficiently move in all directions, including 360 degree rotation and viewing straight down.
