Product Overview This device is a four-channel embedded network DVR designed for automotive safety. It uses an embedded processor and embedded operating system, combining video/audio compression/decompression, GPS/Beidou, and car recording. The technology of the instrument and large-capacity hard disk storage makes the system highly intelligent and highly stable, and can be widely used in various fields such as automobiles, ships, trains and the like.
The basic function of the product is the compression mode of the audio and video digital signal. The video data is compressed by ISO14496-10 (H.264), and the compression ratio is large, which ensures the minimum storage space under the condition of better picture quality; the audio is compressed by G711u, and the sound quality is better. The distortion is small.
Audio and video digital signal recording mode storage format 8-level image quality is adjustable:
4-channel 1080P/960P/720P: (stream size: (1.0Mbps-6.0Mbps)/channel) to meet the needs of different customers.
The storage space supports 2.5-inch SATA hard disk, which supports up to 2TB and automatically loops over the storage.
Image quality image resolution monitoring for monitoring, recording, and playback:
4-channel 1080P/960P/720P: 1920*1080/channel; recording: 1920*1080/channel; playback: 1920*1080/channel.
Image frame rate monitoring, recording, playback frame rate of 25 frames / sec or 30 frames / sec.
Monitoring resolution 4 channels 1080P: single channel monitoring resolution 1920*1080.
Playback resolution 4 channels 1080P: single-channel playback resolution 1920*1080.
Total resources 4 channels 1080P/960P/720P:
Support 4 channels of 1080P (1920 * 1080) simultaneous recording, a total of 120 frames;
Support 4 channels of 1080P (1920 * 1080) simultaneous playback, a total of 120 frames;
Video and audio synchronous recording function supports video, audio, GPS/Beidou positioning data synchronous recording. When playing back, the video and audio data can be played back synchronously. When playing back through software, the video, audio, GPS/Beidou can be positioned. The data is played synchronously.
Video and audio intrusion detection function When the device detects the motion of the object in the camera surveillance area after the motion detection recording function is enabled, it can start recording, trigger the alarm, alert the size, position, sensitivity, number of zones, and enter the alert or remove the alert. Other functions can be set.
Video signal loss alarm function When the video signal is lost, the device sends an alarm signal through the network, the response time is ≤ 5s, and the alarm log is recorded. Video signal loss detection is not performed on video channels that are not recorded.
The alarm linkage function supports 8-channel alarm input (high-level trigger (8-36V)), one-channel alarm output (relay output, maximum 500mA current, normally open), when the 8-channel alarm input is triggered, the video and audio recording is started ( 30-330s, can be set), the alarm output closing time can be set (5s-330s), and the alarm signal is sent through the network, the response time is ≤1s.
Alarm pre-recording function In the alarm recording mode, the alarm pre-records more than 5s of video, audio, positioning and other data;
The full-duplex function can retrieve and play back the recorded video and audio data under the condition of full load recording, and does not drop frames; the alarm video file and the real-time video file mark display, easy to view.
The fault alarm function has a fault alarm function. When the host generates a fault, the alarm output is turned on, and the external alarm prompt will continue to work for a duration of not less than 5 minutes.
Operation status self-test and fault recovery function During the running process, the RUN light will flash continuously and continuously detect the running status of the equipment. If the fault occurs, the equipment recovery time is no more than 3 minutes.
Control of the front-end device and multi-channel real-time monitoring and switching function The device can control the camera with the PTZ. The default protocol (RS-485, PELCO-D protocol, 9600 baud rate), 4-channel 1080P/960P/720P : It can realize 4 channels real-time and switch monitoring.
The networking function has a networking function. It can be installed on the computer side to integrate our CMS remote monitoring software with the 3G network integrated in the device to realize remote monitoring of any vehicle.
The data backup can be performed through the USB interface of the host, an external USB flash drive, and the data segment recorded on the hard disk is backed up;
The data segment recorded on the hard disk can be remotely downloaded through the network;
Remove the hard disk box installed on the device, connect it to the computer through the adapter provided by our company, and play and download the data in the hard disk through our special software. You can also use the software to copy the data in the hard disk or The downloaded data is converted into a universal AVI file format for easy playback by other playback software.
Operation authorization, data encryption and data security device operation have a password, the default password is "6666"; the data storage in the hard disk uses a proprietary file system, which has the functions of encryption and data security.
Logs and alarms received by the log function device during operation are generated and recorded in the hard disk. The last 10 log messages can be viewed in the host. The host hard disk can be connected to the computer to view all log information. .
