Decoding is the opposite of encoding in that it describes the process of unpacking a video file and presenting it to the user, such as when playing back on an NVR or DVR. Decoding capabilities vary between devices as some may only support playback of H.264 video whereas others may support H.265 & H.264. Resolution is also important when taking into account the capabilities of a device. If the resolution of the video file is higher than the device can support, then it will not be possible to view the video.
Encoding describes the process of converting a given video input into a digital format. During this process the video is compressed using a codec code such as H.264 or H.265 which is a large factor in the overall size/bandwidth of the final video files. This process occurs wether video is being recorded by a cctv camera or captured by a smartphone.
Many Dahua cameras have a built-in video analysis based on intelligent algorithms which can be configured to trigger events based on Tripwire, Intrustion & Abandoned/Missing. These events can quickly and accurately detect targets in a specific area, enhancing monitoring efficiency. Also available is the ability to support face detection, this can quickly capture a face and create an event on an NVR. In addition the camera also supports intelligent tamper detection, through dramatic changes in the scene it will send out warning information to ensure effective monitoring. Smart features include; defocus, facial detection, intrusion detection, scene change, ROI (region of interest) & tripwire detection.
Intelligent Video System
Some Dahua cameras also support more advanced intelligent features such as peope counting and heat map in addition to basic Ultra Smart Functions.
People counting can be used to monitor the amount of people entering & exiting an area. Reports can be run daily, weekly, monthly or even yearly to provide the best analytical information available. Heat Map can be used by analysing a scene for movement over a long time period, the result of which is a overlayed heat map which indicates the busiest areas on the image. This feature can be used a powerful analytical tool for businesses such as shops & supermarkets
When encoding video, advanced algorithms are used to compress the video file and store it on a digital medium such as a hard drive. The main differences between the various compression standards is efficiency, with each new standard requiring less bandwidth than it’s predecessor.
Remote Connectivity Including Smart Phone Access
You can view your IP camera anywhere in the world using a PC or on your smartphone, including viewing live and recorded footage.
Power Over Ethernet (POE)
Power over Ethernet (PoE) allows power to be delivered via the ethernet cable, removing the requirement for dedicated power supplies. Many NVRs, switches, IP cameras and PTZ's support PoE, allowing these devices to be powered via the network infrastructure itself. Many PoE standards exist today (model dependant).
PoE (802.3af) provides 48v DC up to 15.4 watt with a maximum transmission distance of 100m.
Poe+ can provide almost twice as much power over a single ethernet cable than PoE, providing up to 56v DC up to 25.5 watts with a maximum transmission distance of 100m.
Hi-PoE allows for a significant increase in capabilities of cameras and other devices, leading to a more powerful and effective security solution. Hi-PoE provides 56v DC up to 60 watts, twice the capacity of PoE+, with a maximum transmission distance of 70m.
ePoE has been developed by Dahua Technology to allow for long distance PoE transmission of up to 800m at 10Mbps. When two Dahua ePoE devices are to be connected to each other, this greater transmission distance can be taken advantage of.
