Security has risen to the top of the list of crucial global concerns in recent years. Impacted by the pandemic, energy crisis, and economic downturn, the global crime rate, especially violent crime rate surges incredibly. Consider New York, United States, as an example. According to Fox News, violent crimes there have reached unprecedented levels in the last two years. FBI data shows that the number of murders there increased by almost 30% in 2020 compared to 2019. Homicide rates increased by 5% by 2021 in major American cities all over the nation, according to data released in January by the Council on Criminal Justice. As a result, people increasingly prefer a comprehensive home security system. Additionally, the growth of the Internet of Things (IoT) and the incorporation of artificial intelligence both contribute to the rise in home security system adoption. Market research indicates that the size of the global market for home security systems will increase from USD 56.9 billion in 2022 to USD 84.4 billion by 2027, with a CAGR of 8.2% over the forecast period.
Smart Door Lock: The First Line of Defense
Generally speaking, the home security system includes doors, locks, alarm systems, lighting, motion detectors, and security camera systems. Among them, the first guard that protects home and prevents home invasion is the smart lock. A smart lock is an electromechanical lock that can lock and unlock a door using instructions received from a phone via Wi-Fi or Bluetooth. The majority of smart locks are installed on mechanical locks, and they essentially improve the standard lock in terms of functionality. Additionally, it controls access, sends signals for the various roles it oversees, and performs a few other crucial tasks related to the device’s status. A smart lock can protect your home with strict access controls, using an app, PIN code, or fingerprint to open the door instead of fumbling for the physical key to reduce the likelihood of robbery. A smart lock also extends its benefits to the safety of the private property.
Unlike the majority of conventional entry door locks, which are constructed with a mechanism module, smart locks are driven by electronic and drive systems. Shenzhen ZHAOWEI Machinery & Electronics Co., Ltd. (hereinafter referred to as ZHAOWEI), a drive system solutions provider, researches and develops gear motor drive systems for a smart lock. To improve door lock reliability, ZHAOWEI embeds a gear motor drive mechanism into the door lock cylinder system. The system’s unlocking speed, safety, and lifespan are all increased thanks to the benefits of worm and gear set transmission. The micro gearbox employs a multi-stage transmission that goes from Stage 1 to Stage 4 and uses different settings for basic locking. Then, in response to the clutch motor’s driving requirements, the reduction ratio, stator speed, and torque are adjusted. As a result, it is possible to install intelligent gearboxes with small frame sizes, high torque, and efficiency levels. The awkwardness brought on by door locks that won’t open is no longer necessary to deal with.
Security Camera: The Eye to Deter Burglary
“Burglary”, by definition in the Cambridge English Dictionary, is the crime of forcibly entering a building or other site with the intention of committing a crime. Theft is the most common form of the offense. The majority of offenders target residences that appear simpler to enter. According to a recent study from the University of North Carolina at Charlotte, the majority of burglars took into account the existence of deterrents including alarms, outside cameras, and other surveillance equipment while evaluating a prospective home or business target. Before committing a burglary, almost 83 percent of the criminals stated they would try to see if an alarm was present.
Based on years of R&D experience on gear motor drive systems, ZHAOWEI launch solutions for security cameras, which combine the Internet of Things (IoT) with gear motors for security alarm sensors and cameras to help monitor theft and protect the home. In the early stages of development and design, ZHAOWEI employed a complete design platform, achieving automatic structural design with an involute planetary gear system, bevel gear, and face gear. ZHAOWEI has decreased the impact speed of meshing and set a range limit on the ratio of meshing-in impact speed to meshing-out impact speed by optimizing gear parameters including the modification coefficient, tooth coefficient, pressure angle, and center distance. These actions decrease the noise generated during use.
Besides, ZHAOWEI has made optimizations in service life and product quality. During the design stage, ZHAOWEI uses kinematics simulation to verify the smoothness and local interference of the gear pairs. The tooth surface strength of spiral teeth and bevel gears is also examined and tested using finite element analysis technology. During injection molding, variations in cavity pressure are monitored and detected using cavity pressure technology. Gear motors for rotating phone cameras, stepper motors for pop-up cameras, drive systems for conference video systems, gear motors for auto-focus cameras, and other models are available for the gear motors used in the camera drive systems.

In 2020, FBI reports nearly 8.9 million criminal offense, with 60.5 percent of them being reported as crimes against property, 25.2 percent as crimes against people, and 14.3 percent as crimes against society. Burglary, armed robbery, auto theft, and arson are examples of property crimes. Additionally, the availability of video surveillance served as a powerful deterrent. Nearly 60% of the thieves indicated they would take cameras or other video equipment into account when choosing a target, and more than 40% stated that would cause them to select a different target. Consequently, a home security camera can effectively discourage burglars, protect reliable evidence, and react quickly. In partnership with manufacturers, ZHAOWEI is dedicated to making the world safer.
