While secure and encrypted drives can protect your data from falling into the hands of thieves, scam artists, and other bad actors, rugged drives provide protection from the elements (dust, sand, and water) as well as from tumbles or other accidents. A good percentage of secure drives are also ruggedized; we think of encryption and ruggedization as two sides of the same coin. We have a separate roundup of rugged drives at the preceding link. 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.

After that carefully unplug the SATA cable and power cable from the hard drive. A simple mistake can damage the pin. So be careful when unplugging. Maximum 180TB/year workload rating—3× the workload rating of desktop drives—for reliable performance in write-intensive surveillance systems 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.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.

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. 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.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: A good hard drive that is specially designed for a surveillance system can record 24/7 nonstop in your DVR/NVR system. It is a very essential component for surveillance video storage. 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. There have a few things that must be considered before buying a hard drive for your surveillance system.

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. If you install your surveillance system with less than 10-12 cameras then use the DVR for installation. 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 good hard drive that is specially designed for a surveillance system can record 24/7 nonstop in your DVR/NVR system. 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:
