Professional Surveillance Camera Installers in GTA
IP Camera has taken over the world of CCTV cameras over the last few years. IP Cameras provide clear high resolution video footage compared to analog cameras.IP Cameras are popularly used for surveillance . They are called IP cameras because they use internet protocol for communication. IP Cameras come with many advanced camera features. Following are some of those features.
Focal length
Selecting the right focal length for the camera will decide how large the objects will appear in the camera footage and what viewing angle is visible. Most common focal length is 2.8mm and it gives approximately 90 degrees viewing angle. Higher focal lengths gives narrow viewing angles but objects appear large and closely.
PTZ stands for Pan-Tilt-Zoom. Pan, tilt & Zoom functionality is achieved through the video recording software or by using a joy stick. While pan and tilt physically moves the camera in different directions to survey the area around the camera and Zoom helps to focus in on an object detected by the camera. These features are very useful when monitoring a large area such as a parking lot outside a building.
Frame Rates
Frame rates measures how many video frames are captured by the IP camera in one second. A
frame rate of 40 means , the video camera captures 40 video frames every second when it records video. If the monitoring area has fast moving objects it is desired to set the frame rate to high. High frame rate and the resolution will
need more storage space for the recorded video. High frame rates also need higher bandwidth for sending the video images to the Network Video Recorder (NVR).
Power over Ethernet (PoE)
With power over Ethernet, single network cable (I.e CAT6) is used to send power to the camera and for network connectivity. This feature is very useful in places such as warehouses, manufacturing floors where it is difficult to install electrical wiring.
HD Resolution
High definition (HD) cameras generate detailed images. Helps to identify details such as faces, vehicle number plates, small objects etc. IP cameras can record full HD video (1080P) or better. In pixel terms it is 1920 X 1080.
Camera types
Different IP cameras have their own use cases. IP camera installers need to select the correct type of camera for use cases. Most commonly used IP camera types are
Dome Cameras
Most commonly used in indoor applications. Most dome cameras have night vision capabilities too.
Turret Cameras
Most commonly used for outdoor surveillance applications. Typically they with stand weather changes and also has good IR capabilities for night vision.
PTZ Cameras
Provides pan tilt & zoom capabilities in the camera. These IP cameras are equipped with a motor. They can also be powered with PoE .
Bullet Cameras
Used to view a specific area with better focus. Generally provides narrower viewing angle compared to Dome type cameras. Can be used in both indoor and outdoor applications.
Video Compression
Video compression also referred to as codec compresses video files stored on Network Video recorder (NVR). Commonly used compression schemes are H.264 , MPEG compression and MPEG4 compression. H.264 is the newer technology that is most efficient compared to other two codecs. Compressing video files help to reduce the bandwidth usage and the storage space used for video recording.
Latest in Video coding is High Efficiency Video Coding called HVEC. HVEC is also referred to as H.265. This coding standard helps with latest 4K camera deployment to transmit more data using the same network
