Existing real-time CCTV video encryption systems use separate encryption/decryption equipment and have problems such as increased economic costs due to additional equipment, video delay due to encryption/decryption processing speed, and compatibility with existing installed equipment. Overcoming this, the ‘multifunctional CCTV control system for security based on video encryption technology’ is equipped with an encryption module on existing CCTV cameras and recorders, so it does not require separate encryption/decryption equipment, thus securing economic feasibility. It is possible to build an optimized system by solving the image processing speed delay problem using optimized encryption and decryption technology, and it is equipped with an encryption/non-encryption mode that can utilize existing non-encryption equipment as it is, with excellent compatibility, so that sequential system replacement is possible. It is a system that can reduce the initial introduction cost as well.

In addition, this system overcomes various problems of existing commercially available VPN routers and CCTV systems using encryption and decryption equipment, and secures economic feasibility and the best security, 'VPN-based CCTV system and monitoring method using it (Patent No. 10-2277014)' was applied. By using encryption tunneling technology to manage the CCTV system based on encrypted communication, backdoor and hacking damage are fundamentally blocked. In addition, it is a multifunctional CCTV system with a very high security level that can prevent leakage of personal information and industrial secrets.
