AHD Camera 1080p – What Is The Difference Between 720p And 1080p?
AHD camera 1080p uses the same coaxial cables as traditional analog CCTV cameras and can operate at the same max distance. This makes it ideal for upgrading an existing system.
Watch the video below to see how HD surveillance footage compares to standard analog CCTV. Be sure to adjust the YouTube video player to 720p resolution for a more accurate comparison.
720P Resolution
720p is the high definition resolution for video surveillance cameras. This resolution is higher than the 960H standard definition analog CCTV camera and can capture clearer and sharper images. It is important to consider the resolution of your security camera when making a purchase decision. Your specific needs will determine whether a 720p or 1080p camera is more suitable for your application.
The pixel count of a video camera refers to the number of pixels in each vertical line. It is important to look at the pixel count and not just the manufacturer’s claims of “high definition.” For example, some manufacturers claim that their cameras have a 1.3 mega pixel sensor, but it is actually only 720p. Rather than trust these manufacturers’ claims, you can verify the actual resolution of your camera by using a video quality tester card.
It is also important to note that a higher resolution camera requires more storage space for recording. For example, one hour of HD footage will use up to 675 megabytes of memory. This is a big difference when considering how much space you will need for storing and watching security footage in the future. Choosing a 720p resolution camera will save you memory and will allow for faster streaming of real-time video. This is a great option if you are concerned with the cost of storing and accessing your security footage.
IR Cut Filter
When a camera is used indoors, it must be protected from the sunlight. This is why a camera with an IR cut filter is important. It will block out the unwanted infrared (IR) light that can cause color distortion. This means the recorded video will be clearer and more detailed than if the camera was not using an IR cut filter.
The IR cut filter also helps ahd camera 1080p to protect the image sensor from damage during daytime use. The IR light can cause interference with the image sensor, and this can lead to a blurry picture. The IR cut filter will prevent this by blocking the IR light during the daytime and turning it to black-and-white at night.
AHD CCTV can offer up to 450% more resolution than standard analog CCTV cameras. This allows you to see more detail, and even zoom in and identify faces. It is also more reliable than traditional analog CCTV.
AHD is a new HD analog surveillance technology that uses existing coaxial cable to transmit HD data. It is an alternative to the existing HD-SDI and HD-TVI standards. According to NextChip (Korean chipset manufacturer) and Eyenix, AHD is capable of high-resolution data transmission over long distances while minimizing signal loss. However, it is currently limited in both camera compatibility and configurability.
Wide Dynamic Range (WDR)
When a camera is faced with areas of extreme dark and light, this can make it difficult for the camera to interpret the image; especially if the camera is capturing video. WDR technology helps the camera by balancing out the difference between these extremes.
The way it works is by capturing two frames of an image, one with a short exposure time and another with a longer one. The camera then combines the two to produce an image with high dynamic range. This allows the camera to better wholesale smart camera distinguish objects in the image and avoid them being washed out or rendered too dark.
This is especially important for areas of the camera where there are large windows or glass doors that can cause glare. Cameras installed in lobbies or boutiques may have this problem, and without WDR the glare would wash out everything around these panes of glass.
WDR technology is also helpful in situations where a person is being illuminated by passing headlights from cars or other vehicles. The lighting on the vehicle can be intense and can produce a lot of static, or noise, in the picture. With WDR, the imaging system can correct this by adjusting the intensity of the backlight on the subject, which gives the camera more power to discern the shape and characteristics of that object.
Motion Detection
When you think about it, motion detection is one of the most important aspects of any security camera. It’s what makes the DVR alert you when something moves in front of it, and is how your home is protected from intruders. Unfortunately, the majority of cameras on the market only offer 720p resolution, making it hard to see any details in the footage.
The good news is that ahd camera 1080p is an excellent choice for upgrading your old analog system to high definition video surveillance. The difference is significant: 1080p footage is 225% larger in size compared to analog D1 or 960h resolution. It’s also possible to zoom in on objects or faces, allowing you to identify any suspicious behavior in detail.
You may feel confused about the different HD-over-coaxial technologies (AHD, CVI, and TVI) available in the market, which are often promoted as “the best” in comparison to each other. This article will help you make an informed decision based on the facts.
Unlike IP cameras, AHD cameras use an analog signal which means they can only be connected to CCTV DVRs using coax cables, and can’t be accessed remotely (over the internet) like IP cameras. However, they are still an excellent choice for customers without any networking experience or who want a simple installation process.
