CCTV | Different File Formats for CCTV Footage

 


The CCTV footage format management is essential for maintaining the integrity and accessibility of surveillance data. It’s important to understand the storage needs, that's why it is important to choose a more tailored solution, and follow the best practices to keep your data safe and ensure that the CCTV system remains a reliable and valuable tool in security strategy. Robust storage infrastructure, efficient compression techniques, and prioritization of data security is important to safeguard CCTV footage and to comply with legal requirements. 

The first adopted digital video file format was Microsoft’s ‘AVI’ format, released in 1992. AVI is a versatile, AVI is a container format; meaning it has a standard file header, but the actual data can be encoded in any way desired. All it needed is a codec – a small piece of software installed.

With Digital Video Recorders it was left to the manufacturer to decide how to actually encode and store the video data. With no proper industry standard to follow, each manufacturer create their own file format, and made players to accommodate the format.

Here are some common formats for storing CCTV footage:

AVI, MOV, and MP4
These are universally accepted video formats that are compatible with many media players and video editing software.

H.264
This video format can reduce the size of a video by up to 80% compared to MJPEG and 50% compared to MPEG-4. 

MKV
This video file format is becoming more popular and can include audio, video, subtitles, metadata, and menus. 

WMV
This format offers good video quality but has a large file size. It was developed by Microsoft for Windows Media Player.

Countries with a more robust internet infrastructure can choose to store CCTV footage in the cloud, which can provide ample storage space for large amounts of data. 

Video compression is a process that reduces the size of the original video file and changes the file to another format so it can occupy less storage space and transmit more quickly.

Video bit-rate is the amount of video data that can be recorded at a given second, measured in megabits per second (Mbps). The higher the bitrate, the higher quality video, but the shorter the amount of recording time you get. A full HD video camera offers 1920 x 1080 resolution, but not all full HD cameras record at the same bit-rate. One may record at 15 Mbps, and one may record at 24 Mbps. The one that records at 24 Mbps has a higher video quality, but the file will take up more storage space.

To make CCTV footage easier to retrieve, you can label it with key information like the date, time, and location of the recorded event.

Why do the Philippines have slow internet?

  It isn't that the country's regulatory landscape makes it difficult for internet service providers to put up the necessary infrastructure.  Actually the approval of electronics systems designs and plans in the city and municipal areas isn't difficult, it was most likely because they could not enforce the law. And also corrupt government officials exploit this lack of enforcement to steal money from the telecommunication companies. The Department of Interior and Local Government (DILG), Department of Public Works and Highways (DPWH), Department of Information and Communications Technology (DICT), has released memorandum circulars on RA 9292, Electronics Engineering Law of 2004 regarding its implementation. The Local Government Units should already have a guide in formulating a unified and defined set of procedures in the releasing electronics permit and in the checking and approving of electronics system plans and designs. The country's regulatory landscape NEVER make...

The Distributed Antenna System

A distributed antenna system is most often used to distribute cellular network coverage to heavily populated buildings, such as offices, high-rise apartments, shopping centers or sports stadiums. The Telecommunication facility is one of the major parts of the building utility to provide communications. The building owner shall provide space to house the telecommunication facility of the building. The distributed antenna system is part of the telecommunication facility of the building. The distributed antenna system, is an in-building solution comprising of a number of pico cells to provide wireless coverage and services using 2G. 3G, 4G, 5G, and even 6G wireless access technology. Definite number of antennas constitutes one single sector; this means that these set of antennas are strategically installed inside a building / compoun...

An electronic engineer in the renewable energy sector

Examples of renewable energy sources include wind power, solar power, bio-energy (organic matter burned as a fuel) and hydroelectric, including tidal energy.  Renewable energy engineers develop and design systems to use energy from renewable resources, such as the sun, wind, and water. Renewable resources are energy sources that are naturally and continually replaced. They are alternatives to nonrenewable resources such as coal, oil, and natural gas that do not replenish themselves, and are environmentally destructive. It's crucial to gain specialized expertise. Focus on understanding the electronic components that are vital for renewable energy systems, such as inverters, which convert direct current (DC) from solar panels into alternating current (AC) for use in homes and businesses. Familiarize yourself with energy storage systems, ...
