CCTV

Sep 02

The rapid growth in global AI demand, especially for training and running large-scale AI models, has significantly increased the need for high-performance and high-capacity storage. This includes technologies such as High Bandwidth Memory, high-speed Solid State Drives, and large-capacity Hard Disk Drives. As major technology companies continue to expand their AI infrastructure, demand for storage has risen considerably, resulting in significant price increases and also issues with sourcing stock availability. Industry forecasts suggest that storage prices are likely to remain elevated and continue rising throughout 2026.

As AI continues to drive demand for higher-resolution CCTV and longer recording times, storage requirements are becoming a growing concern for businesses and security professionals. More cameras, higher resolutions and increasing amounts of recorded data can quickly lead to higher storage and infrastructure costs.

Dahua’s Super AI Coding Technology offers a way to tackle this challenge by intelligently reducing the amount of data generated by CCTV cameras, while still maintaining important image detail. By prioritising areas of the image that matter most, such as people and vehicles, Super AI Coding can help reduce storage requirements and network bandwidth without compromising the quality of critical footage.

Key benefits of Dahua Super AI Coding

  • 30–50% less storage required – Super AI Coding reduces the amount of data that needs to be recorded, potentially allowing you to use smaller HDDs or keep recordings for longer on the same storage capacity.
  • Up to 50% reduction in network bandwidth – Less video data needs to be transmitted from the cameras to the NVR, reducing network traffic and making better use of existing network infrastructure.
  • Maintains important image detail – Rather than simply reducing the bitrate across the entire image, the system intelligently allocates bitrate to important objects, particularly people and vehicles. This helps retain clearer details where they matter most.
  • Better image quality than simply lowering the bitrate – Conventional bitrate reduction can introduce problems such as blocking, blurring, motion trails and other compression artefacts. Super AI Coding is designed to reduce the overall bitrate while avoiding excessive loss of detail on important subjects.
  • Potentially lower system costs – Because less storage and bandwidth are required, the technology can reduce the cost of HDDs, network infrastructure and potentially the overall CCTV system. Dahua gives an example where a system requiring 14TB with H.265 could use 7TB with Super AI Coding for the same stated recording scenario.
  • Particularly useful with today’s higher HDD prices – The idea is especially relevant for larger CCTV systems where storage is a significant part of the system cost. Instead of buying additional HDD capacity to maintain retention periods, Super AI Coding can reduce the amount of storage needed.

In simple terms

Super AI Coding is essentially about getting more CCTV recording out of the same amount of storage and network capacity, without sacrificing as much image quality where it matters.

Instead of treating every part of the image equally, it gives more of the available bitrate to important objects such as people and vehicles, while compressing less important parts of the scene more heavily.

The United Kingdom & Ireland have strict regulations regarding the use of Closed-Circuit Television, especially when it comes to covert surveillance. Covert CCTV refers to the use of hidden or discreet cameras to monitor individuals without their knowledge or consent. These regulations are in place to balance security and privacy concerns. Please note that regulations and laws can change over time, so it’s essential to verify this information with your own research, using up-to-date reliable sources or consulting with legal professionals.

GOV.UK

Guidance on the user of domestic CCTV

Here are some general rules regarding covert CCTV in the UK:

Lawful Basis

Covert CCTV must have a valid legal basis for its use. Achieve this by demonstrating that the use of covert surveillance is necessary for specific lawful purposes. Such as the prevention or detection of crime, safeguarding national security, or protecting the public.

Regulation of Investigatory Powers Act 2000 (RIPA)

The RIPA governs the use of covert surveillance by public authorities. This includes government agencies and law enforcement. It sets out the legal framework and requirements for using covert CCTV for certain purposes.

Human Rights Act 1998

The Human Rights Act incorporates the European Convention on Human Rights (ECHR) into UK law. Under this Act, individuals have the right to privacy (Article 8), and the use of covert CCTV must not infringe upon this right without a legitimate reason.

Data Protection Act 2018 (DPA)

The DPA governs the processing of personal data, including data obtained through CCTV cameras. If Covert Closed-Circuit Television captures images of individuals, it falls under the scope of the DPA, and data controllers must comply with the data protection principles.

Information Commissioner’s Office (ICO) Guidelines

The ICO provides guidelines on the use of CCTV, including covert surveillance. Organizations and individuals using covert CCTV should familiarize themselves with the ICO’s guidance. This will ensure compliance with data protection and privacy laws.

Proportionality and Necessity

Covert surveillance should be proportionate to the purpose it aims to achieve and should not be used unless other less intrusive methods are not feasible or adequate.

Signage and Notification

In most cases, the use of overt CCTV requires signs to be displayed. Therefore, notifying individuals that they are being recorded. However, for covert CCTV, there may be exceptional circumstances where such signs are not required. But the necessity for covert surveillance must be justified.

Confidentiality and Access Controls

Access to the recordings obtained through covert CCTV should be limited to authorized personnel. They should also be kept confidential to protect individuals’ privacy.

Retention and Deletion

Recorded footage retained only for as long as necessary. Footage securely deleted once no longer required.

Consultation with Legal Professionals

Given the complexity of data protection and surveillance laws, it is advisable for organizations and individuals considering the use of covert CCTV to seek legal advice to ensure compliance with all relevant regulations.

    These regulations and guidelines are essential to ensure that the use of covert CCTV respects individuals’ rights to privacy while still allowing for necessary security and surveillance measures.

    OCULi Wireless PIR Camera

    OCULi is a product range of battery powered wireless, PIR motion sensors which have integrated colour/monochrome cameras and infrared illuminators. These products provide rapid video verification of alarm events using the mobile phone 3G network. A dedicated cloud server and web portal provides a full monitoring system as well as an easy way to set up and control the detectors. Alarms and alerts are sent to the OCULi mobile phone app as Push Notification as an alternative means of monitoring.

    System Overview

    OCULi uses the mobile phone 3G network and can be sited anywhere there is a network signal available. Simply sign up to SIM usage on a rolling monthly contract and you are ready to go. (SIM price includes the use of the cloud server). Images are streamed over 3G giving exceptional speed and quality of delivery. Connection time to the network using our roaming SIM is fast and non network specific so the strongest signal will always be used. All video & data is stored on the SD card and cloud server until it is deleted by the user.
