CCTV footage has crucial data, and if it is stolen or corrupted, it is a stressful situation. Every footage contains vital evidence. Nowadays, security professionals face this problem. This complete instruction helps you to recover your valuable data.
Understanding the problem: The DVR system composites and records data on a continuous basis. This constant operation leads to power outages, corrupted files, and hard drive failures. In certain cases, there is a chance that you will lose footage forever. Some DVR brands, such as Hikvision and Dahua, use a unique file system. The generic tools fail to recognise the process as the complexity increases in the data recovery process due to variability.
Causes of Corruption
- Power failure can cause damage to the computer system, and sudden voltage issues can harm the hard drives and damage the file system. Battery backups play a crucial role in preventing these problems.
- Physical damage also creates damage to hard drives as they are sensitive and can be corrupted instantly. Water and fire can damage crucial components; water can ruin the electronics, and fire can melt the components.
- Human error also contributes to the various challenges. Files can be corrupted due to improper shutdown, and accidental deletion can cause footage to be lost and data to be erased. The staff should be adequately trained to minimise the risk.
Initial Valuation Steps
- Begin with basics. Keep an eye on the power connection. Precisely check the cables. Go through any physical damage sign and write down everything you need.
- Closely examine the hard drive. Clicking spells trouble. If they crush any noise, it leads to failure. A normal drive works quietly, but a wired sound means a problem.
- Carefully check the DVR and inspect the power on correctly. You should watch any strange behaviour or error message notes to record all the symptoms.
Expert recovery techniques:
- Specialised CCTVs services are available, and they are trained to handle the inspection system carefully. The success rates are high, and the tools are used for professional purposes and are majorly used in critical cases.
- They provide work with expertise and prevent further damage, as they use specialised tools and techniques. They provide valuable expertise.
- The Cost can vary between services. Critical services cost more. Increase in prices due to rush jobs. Regular services will lead to lower costs in the future. The budget can be made accordingly.
DIY recovery Methods
- Software solutions exist. Some require payments, while some are free tools. Research wisely and choose a reputable program.
- First of all, create the exact copies. Working on copies is easier as the original copies are protected. This is the crucial step, and mistakes are less costly in this step.
- To prevent accidents, always use blockers. They protect evidence and maintain integrity. It is helpful in legal cases.
Technical recovery steps
- Take no shortcuts, follow proper safety procedures and apply appropriate power procedures.
- Scan for file and video formats.
- Identify file fragments and recreate them when possible.
- Check the file structure, repair and resolve the issues and maintain the data integrity.
Specialised DVR tools
- DVR examiners have knowledge about all the formats and know how to rebuild video files, but this costs money.
- The recovery of CCTV footage works very well. It extracts video directly, but it focuses on specific brands.
- For example, PC-3000 is a professional grade. It mainly fixes the physical issues. There is a need for training, and it costs thousands.
Preventive Measures
- Always install the UPS System. They help to prevent power issues, allow proper shutdown, and protect hardware.
- Always use backup footage regularly, store the copies separately, and follow the 3-2-1 rules.
