Features:

Adopting an integrated structure design, the portable host integrates network switching functions, integrates 4 switching network ports, and supports POE power supply.

Support the access of 720P/1080P high-definition network cameras; support the adjustment of SD and HD modes of high-definition cameras. Provide portable temperature and humidity probes, support real-time display of temperature and humidity information, and use USB interface to insert and integrate. It can be automatically superimposed into the video without special access settings, and the superimposed picture and position can be adjusted arbitrarily;

Support picture-in-picture synthesis encoding, support H.264 video encoding format, encoding resolution support 1080P/720P/4CIF/CIF/QCIF, video frame rate not less than 25 frames/sec;

Support G.711 audio encoding format;

Supports encryption of the code stream during the encoding process to ensure information security during transmission and storage. The encrypted code stream must pass through a dedicated player and verify the password before it can be decoded correctly;

The device has the function of CD synchronous burning, and the burned CD has its own player, which can automatically run on the PC and play the video;

When the system performs simultaneous recording and recording, you can choose 2 recordings, 1 recording and post-recording and other modes.

Support to replace the new disk halfway after burning the full disk, and the video in the new and old disk can be guaranteed to be continuous and complete;

The recording status can be displayed on the client in real time, and the recording status includes the remaining capacity of the disc, disc error information, etc.;

Supports backup recording of the video in the hard disk of the host;

Possess 4 USB2.0 ports, used to connect mouse, U disk, mobile hard disk;

With audio input and output interfaces;

With the video recording function, support the input of key marks, the player can quickly locate the corresponding recording time according to the key marks during playback.

Seamless disc changing function, during the interrogation recording process, the interrogation disc changing function is supported, and the videos of the front and rear two discs are not lost.

The system uses a slot-in DVD drive, supports simultaneous burning of dual discs, burning encryption, and password verification is required when opening the disc.

System design The dual cameras have built-in omnidirectional pickups to ensure dual-channel sound collection. The dual cameras can perform redundant protection for the built-in pickups. The built-in pickups use AGC automatic gain circuit and DSP noise reduction.

After the system is connected to the AC power supply, it will charge the battery pack. In the event of an unexpected power failure, it can be used as a UPS power supply. The smart battery can display the charging status and remaining power.

The system has integrated electronic transcripts and file data management functions, without the need for additional equipment to install interrogation software to achieve this function.

The system supports business-based data authority management, and only interrogation-related users can access data such as cases, ledgers, and videos;

The system can manage departments, users, roles, equipment, interrogation rooms, permissions, logs, etc.;
