Most security camera footage is stored for 30 to 90 days. This is true for hotels, retail stores, supermarkets, and even construction companies. Banks keep security camera footage for up to six months to comply with industry regulatory requirements.

You have the right to request CCTV footage of yourself. You need to make a request to the owner of the CCTV system. You can do this either in writing or verbally. The owner’s details are usually written on a sign attached to the camera, unless the owner is obvious (like a shop).

Go to the location and ask nearby stores or ask the property management company if they have surveillance of the area. The Freedom of Information Act can also make obtaining video from government-owned cameras obtainable. Getting to the scene early is imperative.

Most home security cameras are motion-activated and will record when they detect motion, as well as send you an alert. Some can record 24/7, which is known as continuous video recording (CVR).

Accidental damage may have been caused to the DVR or the security camera feed. Video footage can be deleted automatically by the DVR itself. This operation is expected, as a security DVR only has a finite amount of storage.

How long can a HDD record for your DVR/NVR?

180 hours

How much can you pack onto a 2 TB drive? About 34,000 hours of MP3s, 80 days worth of video, 620,000 photos, 1,000 of high-definition movies. In a press release, Kingston claims it can carry 70 hours of 4K video.

three to five years

Generally speaking, you can rely on your hard drive for three to five years on average. They found that 90% of hard drives survive for three years and 80% for four years. But this number varied across brands. Western Digital and Hitachi hard drives lasted much longer than Seagate’s in Backblaze’s study.

Causes. There are a number of causes for hard drives to fail including: human error, hardware failure, firmware corruption, heat, water damage, power issues and mishaps. On the other hand, a drive can fail at any time in many different situations.

It is good if you have a backup of your important data. However, if you do not make a backup in advance, and find the components in your drive are still functioning, you can recover data from the dead hard drive with bootable CD/DVD of data recovery software – EaseUS Data Recovery Wizard WinPE Edition.

How much does it cost to recover data from a hard drive? Basic hard drive data recovery costs average between $100 and $700, based on these factors. This price typically depends on the severity of damage and what is required to reach the point of data extraction.

You can also try pulling the hard drive and connecting it to another computer. If the drive has partially failed, you may be able to copy a few important files off it. You may also be able to use a tool like Piriform’s Recuva, which promises “recovery from damaged disks”.

around 10 years

Of course, SSDs mean that most people have to make do with much less storage space. A 1TB hard drive stores eight times as much as a 128GB SSD, and four times as much as a 256GB SSD. The bigger question is how much you really need. In fact, other developments have helped to compensate for the lower capacities of SSDs.

One of the first signs of SSD failure from bad blocks is if your computer takes a very long time when attempting to retrieve or save a file. Unfortunately, no matter how long you try, those attempts will end in failure, because your SSD is suffering from bad blocks. Frequent errors are another sign of bad blocks.

SSD Reliability Factors to Consider. Generally, SSDs are more durable than HDDs in extreme and harsh environments because they don’t have moving parts such as actuator arms. SSDs can withstand accidental drops and other shocks, vibration, extreme temperatures, and magnetic fields better than HDDs.

All in all, SSDs are a great option for day-to-day storage over HDDs, yet, SSDs are not best long term data storage of power off. Anyhow, with the development of new technology, SSDs may be the best option for long-term storage both in use and without usage!

SSDs in general are more reliable than HDDs, which again is a function of having no moving parts. SSDs commonly use less power and result in longer battery life because data access is much faster and the device is idle more often. With their spinning disks, HDDs require more power when they start up than SSDs.
