Hikvision Monitoring Protocol: A Comprehensive Guide17

Introduction

Hikvision Monitoring Protocol (HMP) is a proprietary protocol used by Hikvision surveillance equipment to communicate with central management systems (CMS). It is a closed protocol, meaning that it is not publicly documented and can only be used by Hikvision devices. HMP is used for a variety of purposes, including video streaming, device management, and event notifications.

Protocol Structure

HMP is a packet-based protocol that uses a request-response model. Each packet consists of a header followed by a payload. The header contains information about the packet type, the message length, and a sequence number. The payload contains the actual data being transmitted.

HMP supports a variety of packet types, including:

Video stream
Audio stream
Device management
Event notifications

Video Streaming

HMP supports a variety of video streaming formats, including H.264, H.265, and MJPEG. The video stream is typically encapsulated in a Real-Time Transport Protocol (RTP) packet. The RTP packet contains a header and a payload. The header contains information about the packet type, the timestamp, and the sequence number. The payload contains the actual video data.

Audio Streaming

HMP supports audio streaming in the G.711 format. The audio stream is typically encapsulated in a RTP packet. The RTP packet contains a header and a payload. The header contains information about the packet type, the timestamp, and the sequence number. The payload contains the actual audio data.

Device Management

HMP supports a variety of device management commands, including:

Get device information
Set device configuration
Upgrade device firmware
Reboot device

Device management commands are typically sent using the HTTP protocol. The HTTP request contains a header and a payload. The header contains information about the request type, the URI, and the HTTP version. The payload contains the actual device management command.

Event Notifications

HMP supports a variety of event notifications, including:

Motion detection
Video loss
Alarm input
Device error

Event notifications are typically sent using the HTTP protocol. The HTTP request contains a header and a payload. The header contains information about the request type, the URI, and the HTTP version. The payload contains the actual event notification.

Security

HMP supports a variety of security features, including:

Encryption
Authentication
Authorization

Encryption is used to protect the data transmitted over the network. Authentication is used to verify the identity of the devices and users. Authorization is used to control access to the devices and data.

Conclusion

HMP is a versatile and powerful protocol that can be used for a variety of purposes. It is a closed protocol, but it is well-documented and supported by a wide range of Hikvision devices. HMP is an essential protocol for anyone who wants to manage and monitor Hikvision surveillance equipment.
