Difference between 1080p and 2160p

Difference between 1080p and 2160p 

1080p

1080p (aka Full HD/ FHD and BT.709) is a set of HDTV high-definition video modes characterized by 1080 horizontal lines of vertical resolution and progressive scan(p), as opposed to interlaced, as is the case with the 1080i display standard. The term usually assumes a Wide screen aspect ratio of 16:9, implying a resolution of 1920x1080 (2.1megapixel) often marketed as Full HD.



2160p
2160p is an alternative name for 4K UHD, a resolution supported by UHDTV products and which offers four times the definition of 1080p. The number 2160 stands for a display resolution which has 2160 pixels along the shortest side, while the letter p stands for progressive scan or non-interlaced. In a progressive image, the lines of resolution of the image go from the top of the screen to the bottom. The only planned higher definition format for television is 8K UHD.

Resolution of Network Camera

Resolution of Network Camera
This time I will try to discuss the resolution of the image of the network camera. Resolution which is the number of pixels (pixel) different in each dimension that can be displayed. The greater the resolution of an image, the more have the number of dots and more detailed image will be displayed.
If you want to buy a camera network device that can display video images are detailed and clear, then you should choose a network camera that has high resolution. Currently network video camera technology has a lot to offer features Full HD resolution (1080p).But perhaps for the people of Indonesia arguably the price is still relatively expensive, because there are around 4 million more.

1080i VS 1080p The Difference

1080i vs. 1080p: What's the Difference?

Progressive (1080p) video is considered better than interlaced (1080i), but it's not always clear why; here's what's actually happening on your TV screen.
Today's HDTVs can display beautiful, 1,920 X 1,080-pixel video, but the actual quality of what you're viewing depends on the source material. A lot of the time, you're not seeing exactly 1080p. In fact, most TVs today have two modes with similar names: 1080i and 1080p. Both have the same screen resolution, so what's the difference between the two? Here are five things you need to know:

1080i video is "interlaced." 1080i video plays back at 60 frames per second, but that's a bit deceptive, because it's actually broadcast at 30 frames per second. The TV then displays those frames twice, the first pass is 1,920 X 540 for the even scan line field, and the second pass is 1,920 X 540 for the odd scan line field. The process by which this occurs is called interlacing. It contributes to a sense of motion and reduces perceived flicker.

1080p video is called "progressive scan." In this format, 1,920-by-1,080-pixel high-definition movies are progressively drawn line after line, so they're not interlaced. On paper, that may not seem like a huge deal. But in the real world, what you end up seeing looks sharper and more defined than 1080i, particularly during scenes with a lot of fast motion.
Sometimes 1080p is termed "Full HD" or "True HD," to distinguish it from 1080i or 720p video. Blu-ray discs contain 1080p video at 24 Frames Per Second, and then, using a method known as 3:2 pulldown, display it at 30 frames per second on screen.
Data compression can confuse the issue. Sometimes cable companies will deliver a 1080i picture, but then compress the data significantly in order to use up less bandwidth. The result can mean smeared details or pixelated color gradations in certain scenes. It's still technically HD, and still looks better than standard-definition cable, but it's not as good as it could be.
This also happens with 1080p streaming Internet video, but in that case, it's usually dependent on the speed of your data connection. In fact, Blu-ray is currently the only practical format for watching lots of pure 1080p content. Even the latest Apple TV, which supports 1080p streaming, does so in a compressed format that loses a bit of quality (although it still looks quite good).

Both formats look similar on smaller TVs. As a general rule, you need a larger TV to notice the difference between 1080i and 1080p. Depending on your eyesight, you can probably pick up the difference on a 32-inch LCD if you're particular about it. But most consumers don't really see a marked difference until at least a 42-inch screen, if not larger. In fact, many people are perfectly happy with 720p HDTV sets even at higher sizes; we recently named one, the 51" Samsung PN51E490B4F, best Choice for budget large-screen HDTVs.

1080p isn't even the best anymore. Technology never stands still, of course. Five years from now, you'll probably just want Ultra High Definition (aka 4K) video instead. (For a closer look at 4K video, check out What is Ultra HD?) But for now, if you're a videophile who appreciates a sharper picture, 1080p is definitely the way to go—both in HDTV capability and in the source material you're viewing.

Seven Advantages of IP or Network Camera Surveillance System

Seven Advantages of IP / Network Camera Surveillance System

IP CCTV stands for Internet Protocol Closed Circuit Television. Furthermore, it is also referred to as network or Power-Over-Ethernet (POE) CCTV. IP cameras are digital devices that capture and transmit video footage over a network.

It offers several benefits over analogue systems, such as higher resolution and scalability – more on this later.

IP/Network cameras offer superior image quality, remote access, advanced analytics (AI), easier scalability/installation (PoE), better security with encryption, flexible storage (cloud/NVR), and seamless integration with other systems, making them more versatile and powerful than traditional analog CCTV for modern surveillance needs.

How to Connect an IP Camera to a Computer

 Here are seven key advantages:

1.        Superior Image Quality: Deliver high-definition (HD) or even megapixel resolution with clearer, more detailed images and better digital zoom capabilities.

IP-based CCTV cameras can capture and transmit higher quality images than standard analogue systems. Furthermore, with IP cameras you can zoom in on your footage with greater clarity.

In context, this is highly valuable to a business, particularly when looking to identify an individual, specific characteristics, car number plates and more.

2.        Remote Access & Monitoring: Remote monitoring is made easier by IP security cameras. For example, you can effortlessly see live footage from your computer, tablet, or smartphone anywhere you are with a wireless IP camera in Dubai. Homeowners who wish to check in on their property while abroad or company owners who need to monitor several sites will find this function especially helpful. View live feeds and recorded footage from anywhere via the internet, offering unparalleled flexibility for home or business.

3.        Advanced Video Analytics: Built-in intelligence for features like motion detection, visitor counting, facial recognition, and anomaly detection, reducing manual monitoring.

Your security camera systems can be set up to detect:

·        Smoke

·        Fire

·        Movement of people

·        Change in temperature

For example, if your security cameras are fitted with movement sensors, you will be alerted if the system detects a threat. As a result, your security team can view the footage in real-time. If a security threat is spotted, the relevant action is taken.

If your CCTV system is monitored remotely, your off-site security team will take charge of the situation.

4.        Scalability & Flexibility: Easily add cameras to an existing network and reposition them, using existing network infrastructure (like CAT5/6 cables).

5.        Power over Ethernet (PoE):  A single Ethernet cable provides both power and data, simplifying installation and reducing cable clutter.

6.        Enhanced Security: The majority of IP cameras come with built-in encryption. This helps to keep your data safer when it is transmitted and stored.

Cyber attacks are becoming more of a threat to businesses, month by month, year by year. Securing your data will help protect it from ending up in the wrong hands.

Digital encryption protects video data from unauthorized access, ensuring privacy and secure transmission.

7.        Smart Integration & Storage: Can integrate with other security systems and offer convenient, secure digital storage (cloud or NVR), making data management efficient.

Frequently asked questions

What is a network video surveillance system?

A system of data transmission from video cameras, which is carried out via the Internet, will be considered a network. In this case, both global networks and local ones can be created.

Mandatory network system design:

·        video cameras (analog and/or IP, PTZ cameras);

·        equipment for data processing and storage of video recordings: recorders, servers, computers, hard drives, switches;

·        special software.

Until recently, it was believed that such an organization of video systems is the optimal solution for continuous monitoring of facilities and events. Many users have chosen network surveillance cameras because of their efficiency and simplicity.

IMPORTANT: Analog, IP and CCTV cameras have a number of differences. CCTV (Closed Circuit Television), as a modern generation closed loop system, is no longer analog equipment, and if CCTV is connected to a DVR, it becomes an IP camera.

What is an IP CCTV system and how does it work?

An IP CCTV system uses digital cameras that transmit video over an internet protocol (IP) network. Unlike analogue systems, IP cameras can stream high-definition footage directly to a recorder, computer, or cloud platform for real-time or recorded viewing.

How is image quality improved with IP CCTV cameras?

IP cameras typically offer higher resolution than analogue, with many supporting 1080p, 4K, or even greater. This results in sharper images, better zoom capabilities, and clearer identification of faces, licence plates, and other critical visual details.

Can I access IP CCTV footage remotely?

Yes. One of the main benefits of IP systems is remote access. Users can view live or recorded footage securely via mobile apps or web browsers, allowing for flexible monitoring from anywhere with an internet connection.

Are IP CCTV systems scalable for growing businesses?

Absolutely. IP systems are highly scalable—new cameras can be added with minimal disruption using existing network infrastructure. This flexibility makes them ideal for businesses expecting to expand or reconfigure their premises.

How is footage stored in an IP CCTV system?

Footage can be stored locally on an NVR (network video recorder), in the cloud, or using a hybrid approach. Cloud storage enables off-site backup and remote access, reducing the risk of footage loss through theft or damage.

What smart features are available with IP CCTV systems?

IP systems often include motion detection, line-crossing alerts, intrusion zones, facial recognition, and two-way audio. These intelligent analytics help reduce false alarms and enable proactive security management based on real-time activity.

How does an IP CCTV system compare to analogue CCTV in cost?

IP systems may have a higher upfront cost, but they offer greater long-term value due to superior image quality, scalability, and advanced features. Over time, they reduce maintenance and upgrade costs compared to ageing analogue setups.

4 disadvantages of the network system

Check out the disadvantages of a network video monitoring system:

1.        Requires technically competent system planning and professional installation. It is necessary to keep in mind the compatibility of equipment, lighting parameters, capabilities of the coaxial cable between the network nodes, height and angle of the cameras.

2.        Video signal delays are possible during data transmission and viewing recordings in real time.

3.        High cost of equipment, including license payment for each camera.

4.        High cost of installation, configuration and regular maintenance of the system (2-3 times more expensive than other video surveillance systems).

What type of network does IP cameras use?

Understanding the concept of what an IP camera is will help you easily choose the appropriate type of network connection. IP smart camera systems can operate on many different types of networks, the most popular are the following three types:

·        Wired network: Connect directly to a modem or broadband router via Ethernet cable (RJ45, CAT5, CAT6). This is the fastest and safest way to connect to eliminate the risk of signal interference and information disclosure.

·        Wireless network: IP cameras use a WiFi router to transmit data to and from a wired modem. Wireless networks have slower data transmission speeds than wired networks and are at higher risk of unauthorized access. However, using strong encryption and network customization can minimize this risk.

·        Cellular network: IP cameras can use cellular connections to transmit data. Although data transfer speeds are typically slower than WiFi, mobile networks are more secure and do not require LAN settings. However, these types of cameras are often more expensive.

Should I install an IP camera system or not?

In addition to understanding what an IP camera is, many users also wonder whether they should install an IP camera system or not. The answer is yes! Installing an IP camera system brings many benefits and is an effective security solution for every home, agency, office, and company. Here are some reasons you cannot ignore installing IP cameras:

·        IP cameras eliminate all old faulty hardware, instead using powerful NVR software, which helps manage data and images effectively.

·        The IP camera line delivers extremely clear HD images with high resolution from 720p, 1080p, compared to PAL, CIF, NTSC standard versions on Analog Cameras. This helps the device record every moment and convert the video into a digital stream before transmitting the signal.

·        IP camera equipment allows simple and easy remote observation and control. You can rest assured about the safety of your home, even when you go on business or pleasure trips.


Installing IP cameras is an effective solution to protect family and property security. However, to ensure the camera system operates effectively and safely, you need to pay attention to the following important issues:

·        Choose a reputable installation unit: Choose a reputable and professional installation unit to ensure the construction work is done quickly, safely and effectively. You need to follow the installation process from start to finish and request instructions on how to use it and change your password login information.

·        Check the installation location: Make sure to choose an installation location so that the camera can observe every corner of the area to be monitored. For infrared IP cameras installed outdoors, you should choose a location that is resistant to water, dust and high temperatures.

·        Ensure stable network source: For wifi IP cameras, it is necessary to ensure fast and stable network speed to avoid affecting image quality and video transmission speed. With wired cameras, use good transmission cables to ensure the system operates smoothly and with quality.
