Coax-over AI with HDCVI 2023

Issue 4 2023 Surveillance, Products & Solutions

Dahua Technology has launched its HDCVI 2023 as a continuation of its expansion of analogue technology into the high-definition era, providing global customers with AI-powered over-coax technology.

High Definition Composite Video Interface (HDCVI), is an over-coaxial-cable video standard that enables long-distance HD transmission (up to 1200 m) of four signals (audio, video, data, and power) with just one coaxial cable connecting the camera and XVR. This year’s HDCVI 2023 offers intelligent functions that allows installers and users to achieve one-step HD monitoring without additional configuration.

Real 5 MP 2.0

Real 5 MP supports 16:9 aspect ratio, more vivid colours and better image sharpness. This year, Dahua is launching the Real 5 MP 2.0 mode (available on XVR5000-I3 series), allowing users to achieve real 5 MP resolution at a reasonable price. Its Real 5 MP Mode and 5M-N Mode can be flexibly switched to meet different resolution requirements.

In addition, HDCVI 2023 also offers two 5 MP Solutions (5 MP Pro and 5 MP Value) to meet the different needs of customers (the 5 MP Pro solution is recommended for users that require more powerful performance).

Smart dual light

The Smart Dual Light feature of HDCVI 2023 records full-colour videos and information of key events in the monitored scene. It switches between warm light and IR light when a target is detected, effectively reducing light pollution. It accurately detects real targets and filters out false alarms using a deep learning algorithm from AI XVR. With one-click function on the DMSS app, it offers flexible configuration to switch illumination modes. It also supports the Illumination By Schedule function to customise user’s security, based on their time preferences.

PT camera

HDCVI 2023 offers a new PT camera that features compact design and supports horizontal and vertical rotation, enabling wider area coverage from a single camera without dead angles. Its IP66 protection rating ensures flexible usage in indoor or outdoor scenarios. It adopts quick-to-install design (suitable for wall mount and ceiling mount) that allows for quick and convenient installation to save installation time.

It is also equipped with Smart Area Lighting technology that enables the camera to automatically adjust the brightness and intensity of the exposure, achieving the best filling light performance, and restores more details of the monitored scene.

S-XVR

The final key element in HDCVI 2023 is the S-XVR. In the past, XVR was required to store video information on the HDD. But HDDs have limitations; they do not have capacity options below 1 TB, the price is more expensive, and selection is difficult. The newly released S-XVR has an internal SSD, offering various benefits to installers and users, including:

Cost-saving: It helps save up to 15% of storage costs than normal HDD solutions.

Smart: Its AI Coding in S-XVR focuses on human and vehicle targets while encoding, ensuring the target's image quality while saving 50% bandwidth and storage costs compared with H.265. It has SMD Plus that can recognise human and vehicle figures based on motion detection, which significantly helps reduce false alarms. It also offers Quick Search function (with options for human and vehicle trigger types) that greatly improves searching efficiency.

Stable: The Dahua SSD is equipped with superior 3D TLC NAND FLASH and self-developed D.L.B.A. (Dynamic Load Balancing Algorithm), ensuring stable operation, excellent product performance and longer service life.

Sustainable: In scenarios that require 24/7 constant operation, S-XVR can save at least 38 kWh of power per year, which is equivalent to the power consumption of a 3 W LED light for about 3 years. It has superior power saving advantages compared with HDD solutions.

Simple: The pre-installed SSD of Dahua S-XVR can significantly reduce installation time, saving customers time in choosing hard disks, calculating hard disk capacity, and considering compatibility issues. Dahua also provides customers with SSD compatible programs. Users only need to purchase Dahua SSD and upgrade their traditional XVR.
