Pain Points:

.

 Different installation requires different brackets. Typically, only wall brackets are included in the product accessories; the ceiling mounting brackets need to be purchased separately. Agents must store both of these brackets, which occupies significant warehouse storage space and incurs more transportation cost. Installers need to confirm the installation position first to be able to select a suitable bracket type.
 Installation of dome camera is complex. When installing dome cameras. Installing a ceiling-mounted dome camera generally needs to disassemble the cover, fix the equipment with the top wall using screws, and then and fix the ball cover. This with no doubt takes a long time to complete. What's more, water vapors may enter the device during installation, making the video blurry and unclear.

.

Solutions:

.

 2-in-1 Bracket. It supports both ceiling and wall mounting, reducing warehousing and transportation costs and enabling installers to install PTZ cameras using just one bracket regardless of the application scenario.
 Quick-to-Install Structure. The quick-to-install metal plate and fastener eliminate the need to disassemble the dome cover, reducing installation steps, increasing work efficiency, and reducing the risk of having water vapor inside the camera.
 Remote Adjustment. The PTZ system supports remote camera adjustment for optimal monitoring range. No need for manual angle adjustment on site.

Pain Points:

.

 The structure of certain products require relatively more manpower to install. Inflexible structural design may consume more installation time. Also, cameras used in special scenarios cannot be adjusted in three axes and are not adaptable for various mounting planes.

.

Solutions

.

 Quick-to-Install Eyeball Structure. It offers a fastener design that does not require additional screws, and a clip design that prevents the camera from falling during installation. It is also equipped with a tightening screw that can be used to fasten the camera enclosure, camera body and base structure together, which helps stabilize the device and prevent unnecessary movements. In addition, with just a single tightening screw, the entire camera can be locked to the quick-mount panel base to prevent it from being stolen.
 IP Adjustable Three- Structure. The body of the camera presents a spherical design, enabling it to be flexibly adjusted through tilt and rotation. Also, the circular design of the enclosure can be adjusted through unlimited pan direction. Overall, the camera is adjustable in three axes, enabling it to be easily installed in a wide range of complex and uneven mounting planes.

.

.

Pain Points:

.

 High Labor Cost, High Accident Risk. Conventional bracket structure requires at least two people to install; one to hold the camera and one to install it. This incurs more labor cost and presents high accident risk when installing from high spots.
 High Material Cost. Installers will need a ladder and other equipment just to install the camera.
 Long Installation Time. A traditional bracket usually takes around 30 minutes to install.

.

Solutions:

.

 Quick-mount Structure Design. It has a quick release plate that can be attached to the camera to make it more secure. Its snap joint design does not need additional screws and another person to install the device. One person can install it in no time. It also offers two screw spindles for flexible angle adjustment and a load capacity of 10kg, making the installation more stable and less wobbly. It significantly reduces installation time by 60%.

 xxQ (Lite & Pro) Quick-to-Install Eyeball Camera. It is equipped with a thin quick-to-install panel separated from other components. Only two steps are needed when installing: fix the quick-to-install panel in place and attach the other components.
 Cooper-U Series Quick-to-Install Eyeball Camera. The inside of the outer cover is formed by molding one piece to form the sphere wrapping cavity and the shell disassembling button. It only needs two screws to fix the quick-to-install panel in place.
 Universal Joint Bullet Camera. It significantly eliminates the hassle of constantly adjusting screws and camera angle when installing the device.
 Quick-to-Install PT Camera. The original product package contains two quick-to-install panels (wall mount and in-ceiling mount), providing multiple installation options. Through the DMSS app, the Pan & Tilt function (Pan 0-355° & Tilt 0-90°) enables the user to remotely adjust the camera angle for optimal monitoring coverage.

What is Symmetric Encryption Algorithm?

.

In the modern stage of cryptography, the concept of key secrecy was introduced, giving rise to a new encryption algorithm paradigm called symmetric encryption algorithm.

.

Symmetric encryption algorithm, also known as single-key algorithm, is characterized by the use of an identical key for both encryption and decryption. They can be broadly classified into two major types: sequence ciphers (also known as stream ciphers) and block ciphers.

.

The core of stream cipher encryption is the key (also known as the seed key) that goes through a key stream generator to produce a key stream. This key stream is then XORed with the plaintext byte stream to obtain the ciphertext byte stream, encrypting one bit or one byte of the data stream at a time. The encryption process is illustrated in Figure 1.

.

.

Figure 1: Steam Cipher Encryption/Decryption Process

.

The core of block cipher encryption is to divide the plaintext data into fixed-length blocks and encrypt them using a key, resulting in ciphertext blocks. The plaintext is encrypted on a byte-by-byte basis. The process is illustrated in Figure 2.

.

.

Figure 2: Block Cipher Encryption/Decryption Process

.

Block cipher encryption is achieved by grouping the plaintext. To enhance the security in the encryption process and facilitate grouping, two key points are usually considered: encryption modes and padding modes. As for the specific selection of encryption mode or padding mode, it often depends on practical application scenarios, required security strength, and other factors.

.

The introduction of encryption modes mainly considers whether there should be any correlation between different blocks or whether each block should be encrypted independently. Different encryption modes represent different iteration methods used in the encryption process of plaintext blocks. Table 1 provides the advantages and disadvantages of using different encryption modes.

Table 1: Comparison of Several Encryption Modes

.

The introduction of padding modes mainly addresses the issue of plaintext that is not a multiple of the specified block size. In such cases, the remaining bits need to be padded to match the algorithm's specified block size. During encryption, the plaintext is padded, and during decryption, the padding needs to be removed according to the same padding mode. Table 2 presents several common padding methods in block ciphers.

.

Padding Mode

Padding Method

Remarks

PKCS#7 Padding

If a block represents a data unit of length n bytes, and the original plaintext length is not a multiple of n, padding is added to make it a multiple of n. The padding value used is the length of the padding itself. If the original plaintext length is already a multiple of n, an extra block is added with a padding length of n, and the padding content is set to the length of the padding.

Recommended

PKCS#5 Padding

Similar to PKCS#7 Padding, but with a fixed block size of 8 bytes, the plaintext is padded to a multiple of 8 bytes. If the original plaintext length is n, the required padding length is 8-(n % 8), and the padding content is set to the length value of the padding.

Recommended

ISO 10126 Padding

Padding is applied to make the data size a multiple of the block size. In this case, the last byte of the padding content represents the number of padding bytes added, while the other bytes are filled with random values.

For CBC mode only

No Padding

No padding is used, and the plaintext must be a multiple of the specified block length.

Not recommended

Zeros Padding

The plaintext is padded with zeros to make it a multiple of the specified block size.

Not recommended

Table 2: Comparison of Several Padding Methods

.

Symmetric encryption algorithms encompass various algorithms, such as RC4 and ZUC for stream ciphers, and DES, 3DES, and AES for block ciphers. They are mainly used to address issues related to secure transmission, secure storage, and have a wide range of applications. However, these algorithms also have drawbacks, such as difficulties in key distribution and the inability to provide non-repudiation, which restrict their application in certain scenarios.
