Where is a reputable consulting unit for installing home and business cameras? Join SECOM to find out now through the following detailed article.
Learn about what a surveillance camera system is?
With the ability to continuously monitor 24/7, the surveillance camera system is considered a powerful “assistant” to help ensure safety and security for individuals and organizations. To better understand the outstanding features of this device, let’s explore the detailed content below with SECOM.
Concept of surveillance camera system
Born in Germany in 1942, the surveillance camera equipment system is known in English as Closed-Circuit Television (CCTV), meaning “closed circuit television system”. Specifically, this system will record images/videos, process data, and transmit them to the monitoring screen so users can capture activities taking place in the monitored area.
Currently, CCTV systems are often used in agencies, businesses, factories, private homes and public areas to enhance security.
What is the role of CCTV surveillance camera system?
With comprehensive monitoring and effective storage capabilities, installing a system of camera equipment brings many benefits and plays an important role in many aspects such as:
- Enhance area security: Cameras are often used to monitor and record the activities of individuals and vehicles in areas such as homes, industrial facilities, stores, offices, schools, and hospitals. hospital to ensure safety and minimize crime-related risks in the area.
- Traffic monitoring: Not only serving security, surveillance camera systems are also widely installed to observe traffic situations such as: detecting individual violations, managing vehicle traffic and improving traffic conditions. Improve traffic network safety.
- Infrastructure management: In large-scale industrial and infrastructure facilities, security camera installation services are used by many business owners to monitor production processes and manage equipment.
- Data analysis: Not only has a simple storage function, data collected from security camera systems also plays an important role in the field of analysis and research such as: analyzing human behavior, analyzing Criminal psychology analysis, trend forecasting,…
Advantages and limitations of security surveillance cameras
Advantage
- Detect criminals quickly: With a fast motion sensor system, surveillance cameras have the ability to record images and detect suspicious movements, helping managers limit the risks of break-ins or break-ins. property theft.
- Monitor the general situation: With the ability to “observe” extensively, security cameras can monitor all activities in many different areas such as homes, businesses, schools,…
- Evidence storage: Not only recording images, surveillance cameras also provide data storage functions, creating useful records and evidence for investigating and handling violations.
Defect
- Invasion of privacy: Using the camera for the wrong purpose can lead to invasion of personal space, making them feel uncomfortable and overly controlled.
- High cost: High-end surveillance cameras often come with high initial investment costs and operating costs, especially when deployed in large-scale enterprise environments.
- Easily affected by weather: Cameras installed outdoors are often exposed to rainy and windy weather, causing wear and tear and reducing performance over a long period of time.
Operating principle of surveillance cameras
Surveillance cameras have a fairly simple operating principle. First, the camera lens will capture images and sounds from the surrounding environment through image sensors and microphones, then pass this data through internal processing steps.
In the processing step, data is transmitted to a recording device, called a video recorder (DVR or NVR). This allows users to view live images, playback recorded videos, or access remotely via mobile devices or computers.
Through this process, surveillance camera systems not only provide monitoring functions but also allow data to be stored for future review, thereby improving the safety and security of the monitored area. close.
What does the security surveillance camera system include?
If the user decides to install a system of specialized camera equipment, learning details about the components in the system is an extremely important step. Accordingly, the necessary components for a home camera system and business security camera system will fully include the following equipment:
Camera recorder
This is an important part that plays the role of gathering and processing images from surveillance camera systems, then transmitting data to devices such as phones and computers via the Internet for users. Besides, the recorder also supports many useful features such as image analysis, motion recognition, warnings when detecting problems, and other timer settings.
Camera lens (Camera eye)
The camera lens, or “magic eye”, is one of the most important components of a home security camera system. Accordingly, the quality of the camera will directly affect the quality of the image, resolution and color nuance of the entire observed picture you receive.
Hard drive or NAS Server
Hard drives or NAS (Network Attached Storage) Server are two devices specifically designed to store images and videos from video recorders. Specifically, the capacity of the hard drive or NAS will directly affect the recording time that can be stored. With larger capacity, users will be able to store images and videos for longer periods of time and can retrieve data from many days ago easily.
Power for the camera
Currently, popular cameras such as IP cameras, Analog cameras and WiFi cameras are often supplied with power via a 12V 1.5A adapter. With the power of this power supply, the security camera system can maintain continuous and effective operation even in low-light environments such as night.
Camera sources usually have two main types:
- 12V separate source: This is a single source, with 220V input and 12V DC output with 5.5mm male jack. This type is popular for plugging directly into the camera without needing any wiring.
- 12V total source: Also known as honeycomb source, has input of 220V AC and output of 12V DC, usually wired by hand. There are many types with different capacities such as 5A, 10A, 20A, 25A, 30A, 40A, 50A, suitable for all types of camera systems that require large power sources.
Power supply cord
For 12V honeycomb power sources (with capacities from 10A, 20A, 30A…), supplying power to the camera location is usually done using a 12V power supply cord. For a single 12V 1.5A source, the power supply method is usually to use a 220V power supply cord at the location closest to the camera. Normally, security camera systems for households will use Cadivi wires with a diameter of about 1.5mm to avoid voltage loss and minimize the risk of causing a fire.
Signal cable
The signal cable in the camera system helps transmit signals from the camera to the video recorder (DVR or NVR). There are currently two popular types of cables used in home and business camera systems: Coaxial cable with 2 conductors and CAT5 or CAT6 network cable with 8 conductors. Both types of cables play an important role in transmitting video signals from the camera to the recorder, helping the system operate stably and effectively.
Signal jack
Different from Signal Cable, Signal Jack is used to connect signal wires in recorder devices and camera systems. Accordingly, using appropriate signal jacks between the camera and video recorder is a mandatory step to ensure a solid connection and stable signal transmission between the two devices.
Internet cable
As part of the important components of the security surveillance camera system, Internet cables are used to connect the video recorder (NVR or DVR) to the modem or Internet source of the network operator such as Viettel, VNPT, FPT, etc. .. Specifically, this Internet cable is responsible for transmitting video data so users can access images from recorders on phones, laptops and tablets.
How many types of security surveillance camera systems are there?
There are many different types of security camera systems on the market today. Therefore, to choose the right camera type for their needs, users can refer to the following 5 types:
Wired surveillance camera
A wired surveillance camera is a type of camera that uses a CCD sensor to record images. Accordingly, wired surveillance camera systems provide high quality images, good security and stable data transmission speed. Thanks to the use of direct signal transmission cables, this camera is suitable for monitoring important areas such as offices, warehouses, or public areas.
Wireless wifi camera
Wireless wifi cameras are surveillance cameras that are quick to install, convenient, easy to use and are increasingly popular when installing home camera systems. Wireless cameras are often equipped with many smart features such as: 2-way conversation, motion alerts, 360-degree rotation,… Thanks to these features, wireless cameras help prevent theft effectively and very effectively. suitable for night surveillance.

Currently, there are many different types of Dome Cameras such as wired, wireless, for outdoor or indoor environments.
Infrared surveillance camera
Infrared surveillance cameras are designed to withstand environmental impacts such as sun, rain, snow, dirt, etc. Thanks to that, this camera system is very suitable for monitoring factories and parking lots. , front door area or any place where security and safety monitoring is needed.
New technology surveillance cameras
New technology cameras are characterized by very high image quality and low latency, often widely used in television stations, banks, factories and other locations that require high accuracy in monitoring. However, this system has quite expensive equipment costs and users need to find a truly professional security camera installation service to install and manage easily.
What technology does the surveillance camera system use?
Currently, camera system installation services often provide a variety of different technologies for customers to choose from, including:
Analog surveillance camera system
Analog CCTV systems are the traditional approach to monitoring and recording images. The cameras in this system will convert images into Analog signals, then transmit via coaxial cable to a recording device or display screen. Although low cost and easy to install, Analog systems are often limited in features and image quality. However, this is still a popular choice for basic surveillance applications such as home camera systems.
IP surveillance camera system
Unlike Analog, IP camera systems use conversion and digitization methods directly on the IP camera lens. Then, the signal is transmitted through data recording devices and network cable or fiber optic cable systems. From there, the data is sent to the storage device and the signals are transmitted to the terminal device such as a phone screen or laptop computer to display to the user. IP security cameras are currently more popular due to their clear image quality and high resolution.
Camera system combines Analog and IP
This is a flexible solution for surveillance when combining both traditional Analog surveillance cameras and modern IP cameras in the same system. This allows users to take advantage of both technologies, from the high resolution and intelligence of IP cameras to the simplicity and low cost of Analog cameras. This solution is especially suitable for large businesses, restaurant chains, healthcare systems, schools,…
Devices that support camera viewing
To conveniently monitor and manage home and business camera systems, users can combine one of the following 4 devices:
TV or LCD screen
Used to connect directly to the recorder, helping users view images from the camera system directly on site. TVs or LCD screens are often placed in common locations such as family living rooms, security rooms, and offices to ensure clear visibility for monitoring.
HDMI or VGA cable
HDMI or VGA cable is used to connect the signal between the recorder and TV/LCD, helping to transmit images from the security camera system to the display screen.
- For new generation TV/LCD: use HDMI cable to view images with maximum Full HD resolution, ensuring clear and detailed image display.
- For older generation TV/LCD: use VGA cable to connect, allowing viewing images with maximum HD resolution. Although it does not achieve the same high resolution as HDMI, VGA still provides good quality images for monitoring and observation.
Mobile devices
Typically, remote monitoring via mobile devices is done via cloud code or domain address provided by the manufacturer or camera system installation service. This allows users to access the camera system from anywhere to control the security situation in the most convenient way.
Remote monitoring software via the Internet
Currently, each security camera company usually has its own software for users to access the camera system such as:
- KBVision company: uses KBView Lite software (for Android phones, iPhones) or KBiVMS (for PCs, laptops).
- Dahua brand: use iDMSS Lite software (for Android phones, iPhones) or SMART PSS (for laptops or PCs).
- Hikvision: use Hik Connect software (for Android phones, iPhones) or iVMS-4500 (PC, laptop).
