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.
H.265 supports resolutions up to 8192x4320, including 8K resolution and has a 50% storage reduction compared to H.264.
Power over Ethernet (PoE) allows power to be delivered via the Ethernet cable, removing the requirement for dedicated power supplies. Many NVRs & Network Switches support PoE allowing these devices to deliver power to PoE capable IP cameras via the network infrastructure itself.
PoE (802.3af) provides 48v DC up to 15.4 watts with a maximum transmission distance of 100m.
Resolution determines the number of pixels within a given video image, which in turn determines the amount of definition possible within the video image.
4K/8MP has a resolution of 3840x2160.
Many devices including cameras and recorders support audio recording using external microphones via an audio input or built-in microphone. Audio can be set to record along with video, offering both audio and video evidence.
Changes HCVRs to XVRs. All of Dahua’s NVRs, HCVRs and IP cameras are ONVIF compliant.
Video Graphics Array (VGA) is a video interface used for connecting to televisions and monitors. VGA refers to the types of cables, ports and connectors used to connect monitors to video cards.
High-Definition Multimedia Interface (HDMI) is an audio/video interface used for connecting to HD televisions and monitors.
