Hard drives — guide & FAQ
Hard drives for video surveillance systems are specialized storage devices created for continuous round-the-clock recording of video streams from cameras. Unlike ordinary computer HDDs, such drives are designed for 24/7 mode and optimized for the constant recording of large volumes of data without performance degradation. You can buy a hard drive for video surveillance in Tashkent in the SAT Solutions catalog - we supply drives with a capacity from 2 to 12 TB, designed for recorders of any scale.
Choosing the right HDD for a security system directly affects the reliability of video archive storage. An incorrectly selected drive - an office drive instead of a specialized one - will fail within a few months under the load of video recording. That is precisely why drives specially adapted for such a load are used for video recorders: they are designed for constant recording, have an increased resource and support simultaneous recording from multiple channels. For facilities in Uzbekistan, where power outages are more frequent, the drive's resistance to sudden shutdowns is also important.
Archive depth is a key parameter when designing a video surveillance system. To store 30 days of recordings from 16 high-resolution cameras, several terabytes of space will be required. The correct calculation of disk capacity depends on the number of cameras, resolution, frame rate and whether recording is continuous or triggered by a motion detector. SAT Solutions specialists help calculate the optimal volume for a specific facility and budget.
How to choose
- Drive capacity: calculated based on the number of channels, camera resolution and the required archive depth. For small systems (4-8 cameras, 14 days) 2-4 TB is sufficient; for large facilities with 32+ cameras and a 30-day archive, drives from 8 to 12 TB or several drives are needed.
- 24/7 operating mode: a mandatory requirement for video surveillance systems. Drives not intended for continuous operation overheat and quickly fail. Look for a "for surveillance" marking or an equivalent one from the manufacturer.
- Compatibility with the recorder: most modern DVRs and NVRs accept standard SATA drives, however some recorders have limitations on the maximum capacity of a single drive. Before purchasing, check the list of compatible HDDs for your recorder model.
- Recording speed: for multi-channel systems with high-resolution cameras, the drive's throughput is important. Video surveillance drives are optimized for sequential recording, which is ideal for a continuous video stream.
- Vibration resistance: at facilities with industrial equipment or a large number of drives in one housing, protection against vibration interference between neighboring drives is important.
- Operating temperature: in Uzbekistan, where in summer the temperature in utility rooms can exceed the norm, drives with an extended temperature range and an efficient thermal mode are preferable.
- Warranty period and manufacturer's reputation: for critical infrastructure, choose drives from well-known brands with an official warranty of at least two years.
Applications
- Office and administrative buildings: recorders with 8-32 channels, storing an archive for 14-30 days, drives with a capacity of 4-8 TB.
- Retail facilities and shopping malls: a large number of cameras, often with analytics, require high-capacity drives - from 6 to 12 TB per recorder.
- Manufacturing enterprises and warehouses: round-the-clock video surveillance, recording without gaps, elevated reliability requirements for drives in conditions of vibration and dust.
- Residential complexes and apartment buildings: systems with a large number of cameras in parking lots, entrance groups and the perimeter, long-term archive storage.
- Banks, gas stations, critical infrastructure facilities: maximum requirements for reliability and archive depth, redundancy with RAID arrays is often used.
- Transport infrastructure: video surveillance at railway stations, bus depots and transport hubs of Uzbekistan with round-the-clock recording.
