AP-HLD1004 is RTSP based 4 channel HD DVR display device for network DVR. It can be connected to HDTV as well as support the next generation video codec H.264 with low bandwidth to provide high resolution. It can be used as IP based real time HD CCTV display device for traffic surveillance, environment surveillance, and port surveillance.

The popularity of IP based network DVR has been increasing as much as high interest in HD high performance CCTV. IP based HD NVDR (Network DVR) is hard to approach in spite of its high performance due to bandwidth, network infrastructure, and cost of introduction. IP based HD CCTV solution provides high resolution/low transmit bandwidth at a reasonable price. AP-HLD1004 HD display device is applicable to video surveillance, traffic control, environment surveillance, and port surveillance by combining with various WAN environments such as fast internet, leased line, metro Ethernet. AP-HLD1004 is compatible with various AddPac HD CCTV solutions such as NDVR solution (HD video codec, RTSP distributing server) so that you may build an efficient CCTV environment in accordance with the range of application or the range of field.

H.264 Codec to support HD CCTV Display Solution

AddPac AP-HLD1004 HD DVR is a high quality HD CCTV live display device based on high performance/stable video processor. Video codec supports H.264 codec. It supports component, HDMI interface to connect with HDTV.

Support H1, D1 Multi channel Concurrently

AddPac AP-HLD1004 HD DVR display device supports maximum of 4HD (720P) video images for decoding. It can support D1 (720x480, 1Mbps) concurrently as well as support HD (720P), D1 (720x480) for each channel selectively. Built-in 4 screen splitter supports to look at a screen or 4 screens with full HD (1080i).

Firmware Upgradeable HW Codec

AP-HLD1004 high performance video DSP processor is a programmable structure so that it is capable of improving, modifying, and adding new features constantly. When an additional feature or modification is required, just directly download from the homepage or setting an auto upgrade option. You may use the latest features without much effort.

RTSP based HD Real Time Video Decoder

RTSP protocol is a basic protocol for large scale network DVR system. AP-HLD1004 HD DVR display performs RTSP Client function in input which receives the video bit stream. Output performs the RTSP Server function to transmit the video data to video decoder (RTSP Client) through On-Demand. For the stable packet transmission, transport layer protocol uses TCP protocol as a mandatory. To cope with the various application services such as video decoder in RTSP server output, it is designed to support both TCP and UDP protocol concurrently as an option. HD distributing server is applicable to the various application services. Distributing server output is embedded with RTSP server function to connect with various RTSP client terminals. A hardware based HD video decoder AP-HLD1004 can be a 4 channel RTSP client as well as perform video streaming service in the form of On-Demand.

HD Video Processing (30 Frames per Second)

AP-HLD1004 can process HD (1280X720) image based on H.264 standard (30 frames per second). Depending on the network status, you may specify the frame rate and proper bit rate. You may specify/control the bandwidth of 1M~8Mbps when the broadcasting bandwidth is HD.
