The following wiring diagram shows that how to connect a PoE IP PTZ camera to the NVR and joystick PTZ controller. Wiring Diagram of PoE IP PTZ Camera to the NVR In other configuration, Red are used as 485+ and Black as 485- OR Blue and Green can be used for positive and negative respectively. The Yellow in RJ-45 Cable is positive “+” while orange is negative “-“. Keep in mind that separate 12V DC power supply is needed to power up the CCTV cameras. The BNC cables are used for video signal transmission while the RS-485 cables are used to control the camera movement and rotation by connecting it to the joystick PTZ controller or DVR system. The following wiring diagram shows that how to connect an analog PTZ camera to the DVR and joystick PTZ controller. Wiring Diagram of Analog PTZ Camera to the DVR Now, lets see how to wire analog and IP PTZ cameras to the NVR / DVR and PTZ controller as follow.

They can cover up to 360 degrees rotation covering a large area but significantly reduce the image quality in case of digital zoom and zoom in as it will enlarge the pixel.

ePTZ or VPTZ CamerasĮPTZ or VPTZ (also known as Virtual Pan-Tilt-Zoom) are cameras that digitally pan, tilt and zoom an image into portions without physical camera movement as ePTZ refers to a software function instead of hardware. The resolution rate is 450% better than the analog cameras. In CCTV cameras, the latest HD-CVI technology uses a single coaxial cables to transmit the control, audio and HD video signals up to 1920 x 1080 “2 Megapixel” (1080p video resolution) between transmitter and receiver. HD– CVI is the abbreviated form of High Definition Composite Video Interface. An optional PTZ controller can be used to control the movement manually by connecting it to the DVR and a router switch through RJ45 Cable. So there is no need to power up the cameras via separate power supply as the cat5 or cat6e cables are capable to provide the power and transmit the video signals from the camera to the NVR. The IP camera can be directly connected to the NVR (Network Video Recorder) through PoE cable from cameras and RJ45, Cat5 or Cat6e cables. For this purpose, a PoE injector can be used to the extend the limit of length to additional 100 meters (300 feet). As power and video signals can be transmitted via single PoE (power over internet) RJ45, Cat5, or Cat6e cable, the length cant be extended without additional devices. IP PTZ Cameras has a range of up to 100 meters (300 feet) due to the slandered networking limitation. RS-485 cable can be used to connect the analog camera to the DVR or PTZ controller to control the movement of camera. In addition, separate power cables are needed to power up the cameras.

after 45m (150ft), a 1 ampere camera can be powered up with 3 amperes (Note: Although, it works perfectly, but not a recommended method to do so and exceed the 45 meter (150 feet) limit).Īnalog cameras use the BNC cable for video signal to send to the DVR (Digital Video Recorder). The voltage drop can be reduced by providing the power separably to the cameras or providing high amperes power supply (e.g. Lets briefly discuss the different technologist used for PTZ cameras.Īnalog PTZ cameras has a range of up to 300 meters (1000 feet) but due to high voltage drop, they can only be powered up to 45 meter (150 feet) for video and RS-485 range. There are four basic types of PTZ cameras as follow:

PAN: A PTZ camera can move horizontally (left and right) up to 360 degrees circularly to cover a wide range of area.Let’s see how PTZ camera panning, tilting and zooming. Related Post: How to Install a CCTV Camera? CCTV Camera Installation with DVR.Latest IP PTZ camera can Pan ( horizontally) up to “ 360°” and tilt up to “ 180°” ( vertically) and having the zoom ability of “ 112°” and the optical zoom range from 3x to 30x without reducing the image quality. These motors are used to move the camera “Left”, “Right”, “Up” and “Down”. A special type of motor known as “ stepper motor” is used in PTZ cameras for movement control which operated in periodic steps.
