Frame rate (expressed in frames per second or fps) is the frequency (rate) at which consecutive images called frames appear on a display. The term applies equally to film and security cameras, computer graphics and motion capture systems. Frame rate means the number of frames that your surveillance camera captures per second. Frame is a concrete image within a succession of these that constitute an animation. The continuous succession of these frames produces the idea of movement, what happens because of the minimum differences between them. These have a frequency, which is the number of frames per second (fps) that is needed to get an idea of the movement. Maintain the quality of images while reducing bandwidth by choosing the best frame rate for security cameras. Keep reading to learn how many frames per second is good for a security camera system.
Frames per second, is a way of measuring how many frames your security camera system records per second of video. For example, if your security camera captures 30 fps, it means that it can capture 30 frames in a single second of video. The higher the frames, the smoother the video will be. How many frames per second is good for a security camera? Security cameras with slow speeds (from 1 to around 25 frames per second) appear choppy, however, when presented with speeds of 25fps and higher it’s increasingly difficult to see individual frames. Currently, the industry standard for clear, smooth video even with moving objects, and the best frame rate for security cameras is 30 fps, although the quality of video you're hoping to capture and your network's bandwidth is heavily influenced what frame rate will work best for you. 30 fps is not only the best frame rate for security cameras but, also, the standard rate for your television, since it results in smooth movement of people and objects between frames.
Frame rate also has an impact on the size of your video files. If your storage or bandwidth is limited, by controlling the frame rate you can reduce the bandwidth usage by eliminating unnecessary frames. A common technique is to configure the security camera system in a way in which the speed of the photos is detected movement. Another technique consists of transmitting at a higher frame rate for a local display, and less through the Internet for remote viewing. In many circumstances, a lower frame rate will still record video that is smooth while saving you space and bandwidth.
It is important to know how many frames per second a DVR/NVR plays. For example, a 4-channel DVR that is rated at 60 fps records a total of 60 frames per second. If you connect two cameras to this 4-channel DVR with a capacity of 60 fps, each camera will record at 30 FPS, but if you connect 4 cameras to the unit, each camera will record at 15 FPS. Although this may be acceptable for many, it is not enough to record full-motion video.
Analog Security Cameras capture an analog video signal and transfers it over coax cable to a DVR (Digital Video Recorder). The DVR will convert the analog signal to digital, then compress it and store it on a hard drive for later retrival.Read More
HD-TVI Security Cameras currently support video resolution as high as 1080p by using the same coaxing cabling as Analog Cameras use which, makes it easier for people with old Analog CCTV Systems to upgrade to an HD system.Read More
IP Cameras are able to deliver higher resolution and offer digital zoom and on board digital processing. A higher number of pixels will provide a better digital zoom so you'll see further into the distance without degrading the image.Read More
Megapixel Security Cameras deliver the best image quality available, capturing a super high-resolution image and allowing you to digitally zoom in on specific details with great clarity when reviewing recorded Surveillance videos.Read More
Color Night Vision Security Cameras contain powerful image sensors that are more sensitive to light allowing the sensor to absorb more visible light so the cameras will continue to provide full color video images in low-light conditions.Read More
Thermal Seurity Cameras sense thermal energy instead of using visual light to construct images. Since it doesn't see light, it will see at night as well as it does during the day. It sees through obstructions and its not affected by smoke, dust or fog.Read More
Wide Dynamic Range Security Cameras help to figh natural and artificial lighting. These cameras have a special software which allows them to balance too bright or too dark rooms creating a balanced and high resolution video shot.Read More
Wireless Security Cameras allow you to place them up to 1.5 miles away from your local area network. They use top-of-the-line technology to ensure a secure and reliable connection and offer the same standard features as a wired camera.Read More
Having a security system as necessary as paying for services.The price depends on the features and form factors of the equipment, as well as the amount of devices installed, the distance, whether, and if its a wired or wireless system.Read More
Audio Security Cameras have built-in microphones that allow easy audio recording. Hidden audio security cameras are illegal, so you must get the consent of at least one person in the conversation or hang sign where they are installed.Read More
A Network Security Camera can be described as a camera and a computer combined in one unit. Their significantly high video resolution will allow you to capture more area per camera and zoom-in to enhance minor details.Read More
Image sensor is the element of an electronic camera, which detects and captures the information that makes up the image. This was achieved by converting the attenuation of light waves into electrical signals.Read More
Power over Ethernet (PoE) works by using a single network cable to provide both data connection and electric power over to an IP Security Cameras. This will result in lower cost, less downtime, easier installation and maintenance.Read More
PTZ stands for Pan, Tilt and Zoom. This refers to the capabilities of automated cameras and video recorders. Has the ability to rotate, usually in a full circle, to tilt at different angles up and down, and to zoom in on particular objects.Read More
Video compression techniques consist of reducing and eliminating redundant video data so that the digital video file can be sent through the network and stored. Different compression standards use different methods to reduce data.Read More
Frame rate, fps or frames per second, is the number of frames (images) your camera can take per second. The continuous succession of these frames produces the idea of movement because of the minimum differences between them.Read More
4K security camera is a digital camera with a horizontal resolution of around 4,000 pixels and a vertical resolution of about 2,200 pixels. It is twice as high as the resolution of an existing standard high definition (HD) security camera.Read More
