First, you need to remove the DVR hard drive. So you need a small screwdriver. Then remove the screws. Keep the screw safe for reuse. Encryption is the process of taking readable text or data and encoding it using a key—a random string of bits, generated by an encryption algorithm—so that only someone in possession of the key can decrypt it. Most mainstream encrypted SSDs and hard drives provide what's known as AES 256-bit hardware-based encryption, while most hyper-secure keypad-accessible drives utilize XTS-AES 256-bit hardware-based encryption. During video surveillance planning stage, we often face a question – how many HDDs should I use for my video surveillance system. Estimating or calculating the required video storage can be quite simple by using the formula, or it can be complicated when considering many factors including resolution, frame rate, video compression, and bitrate settings. We herein provide you a freeware which can calculate the video storage requirement of the camera based on many these variable parameters. Using this calculator you can roughly estimate how long can a HDD record in your computer/DVR/NVR. How much HHD space you will need depends on how long you like to store your data as well as your surveillance system area. You may lose your important video due to the shortage of storage capacity. Then carefully remove the hard drive from the DVR by using a screwdriver and keep the screw safe for reuse.

We suggest that you use an exclusive surveillance or professional class hard drive for your surveillance system. Use a DVR embedded with a surveillance hard drive for the scale of a video surveillance system that is equipped with a few HD cameras.

Why A Surveillance System Hard Drive is needed For The Surveillance Security System

Today our technology has developed and now we use very upgraded technology for our surveillance system. The trend for IP cameras is now being observed due to developing technology. The manufacturer replaced the analog cameras with an IP camera that helps to integrate both hybrid NVRs and video management systems. A good hard drive that is specially designed for a surveillance system can record 24/7 nonstop in your DVR/NVR system. Traditionally a desktop hard drive is made to operate for around 8 hours. So the overall workload will be around 10%-20%. It is a low-moderate performance. Maximum 180TB/year workload rating—3× the workload rating of desktop drives—for reliable performance in write-intensive surveillance systems A surveillance hard drive can record 24/7 nonstop. While some other hard drives aren’t able to do this.

A: Yes, you can connect one or a couple of external hard drives to a single DVR. It will increase your recording storage and provide you with long time storage capacity. If you require more than 15 cameras then go for an IP camera and utilize an NVR which will be better to upgrade the system in the future. A normal hard drive has a minimum 45000 hours lifetime but a surveillance hard drive can be used long term. It allows double or triple power-on hours capability, which means it can last for a long period and much longer than any other hard drive device. A: Yes, DVR comes with an internal hard drive. You can also add or replace the hard drive in the DVR system. It is very easy. Read the DVR Hard Drive Replacement for details.If you are using a CCTV hard drive of 2TB, or a CCTV hard drive of 4TB, and you want to replace them and install an 8TB surveillance hard drive. Follow the below instructions to replace the hard drive in your surveillance DVR: There have a few things that must be considered before buying a hard drive for your surveillance system.

A solid-state drive (SSD) uses different technology to remove the spinning parts while a traditional hard drive also has spinning disks. SSD has no moving parts and will last longer. A better brand’s hard drive provides you with better service. So you should choose the best brand that can supply you with a great surveillance system hard drive. We recommend Western Digital. WD is a well-known brand all over the world. Another feature that drive-makers tout and clients covet is the inclusion of a Common Criteria EAL5+ (hardware-certified) secure microprocessor. Such a device, through a combination of true random number generation and built-in cryptography, further protects against drive tampering. Running this simple software, you can instantly estimate the total video storage for your desired storage (number of days) per network camera. Additionally, you can use the formula as below:A surveillance system has to store large amounts of data. It runs intensive management software. It is very important to choose a surveillance system hard drive. Selecting hardware that is professionally designed is the best for your surveillance system. It can eliminate the chance of hardware failure. IP cameras are also better for large areas of installations like airports, shopping malls, and bus stations.
