How to configure motion detection recording parameters using a SD card?

In the Parameter settings, click the Motion Detection page, open the Motion Detection, and set the motion detection area, you can edit the red zone to change the scope of the motion detection area, the value is more large the detection level is more sensitive.

How to configure port forwarding for IPC ?

Typically when one computer communicates with another computer over a network the information is carried using a specific port number. Many ports have specific uses such as email or FTP and a full list of common ports is available on the Internet. It’s not so important to know the full list though you’ll be glad to hear…

You will find that the majority of network devices which are accessible using an Internet browser will be set as standard to port 80, including IP cameras and routers etc. This is due to the standard port for HTTP, or information being displayed through an browser, being port 80.

I would advise that you alter the default port number in the camera to something which is not being used in the list of common ports. We do this for a number of reasons. Like local IP addresses, port numbers have to be unique. If you have your camera on port 80 and your router on port 80 you will only be able to access one of these devices from the Internet using this method. It is also to promote security to your network. It will keep the camera safer if someone was to attempt to maliciously enter your network as it won’t be on the standard port. Don’t worry though, even if someone did find a camera on your network it will be password protected and almost impossible to access without the password.

Remember also that when changing to a custom port number the URL for your camera will change both internally and externally. For example if we changed our camera on http://192.168.0.90 from port 80 to port 4440 we would have to use http://192.168.0.90:4440 to connect to the camera, specifying the port number explicitly at the end of the IP address. This is the same for accessing the camera externally.

How to focus the IPC?

What does 4K mean?

4K UHD is a resolution of 3840 pixels × 2160 lines (8.3 megapixels, aspect ratio 16:9) and is one of the two resolutions of ultra-high definition.

What is counting?

Counting is the action of finding the number of elements of a finite set of objects. The traditional way of counting consists of continually increasing a (mental or spoken) counter by a unit for every element of the set, in some order, while marking (or displacing) those elements to avoid visiting the same element more than once, until no unmarked elements are left; if the counter was set to one after the first object, the value after visiting the final object gives the desired number of elements. The related term enumerationrefers to uniquely identifying the elements of a finite (combinatorial) set or infinite set by assigning a number to each element.

What is ONVIF?

ONVIF (Open Network Video Interface Forum) is a global and open industry forum with the goal of facilitating the development and use of a global open standard for the interface of physical IP-based security products - or, in other words, to create a standard for how IP products within video surveillance and other physical security areas can communicate with each other. ONVIF is an organization started in 2008 by Axis Communications, Bosch Security Systems and Sony.

What is PoE Power Supply?

Power over Ethernet (POE) is a technology that lets network cables carry electrical power.
For example, a digital security camera normally requires two connections to be made when it is installed:

A network connection, in order to be able to communicate with video recording and display equipment

A power connection, to deliver the electrical power the camera needs to operate


However, if the camera is POE-enabled, only the network connection needs to be made, as it will receive its electrical power from this cable as well.

What is Resolution?

In camera, resolution is the number of pixels (individual points of color) contained on a display monitor, expressed in terms of the number of pixels on the horizontal axis and the number on the vertical axis. The sharpness of the image on a display depends on the resolution and the size of the monitor. The same pixel resolution will be sharper on a smaller monitor and gradually lose sharpness on larger monitors because the same number of pixels are being spread out over a larger number of inches.

What is ROI?

ROI (Region of Interest): Maximum 4 regions of interest are configurable for individual streams. Detected faces and license plate can be set as ROI and tracked dynamically. In low bit rate situation the encoding resources would be mainly allocated to the ROI to improve the image quality. The improvements can be controlled through the ROI level. The activation of ROI function would reduce the image quality of other region, while sufficient bandwidth would eliminate the effect of ROI.

What is Rotate Mode? (90°Rotation)

Rotate Mode: Rotate the video image by 90° (anticlockwise), namely switch the vertical and horizontal pixels. For example, the resolution of 1920x1080 is shifted to 1080x1920 after Rotate Mode is turned on.

In Rotate Mode, the resolution in vertical direction is enhanced to adjust to narrow environment such as the corridor, so that further images can be recorded.

Note: In Rotate Mode, the image is rotated by 90° anticlockwise. Thus the camera has to be rotated by 90°clockwise to compensate the image direction.

All the Vantage IPCs support Rotate Mode.

What is SMART Face Detection?(SC)

In digital camera terminology face detection, also called face-priority AF (auto focus), is a function of the camera that detects human faces so that the camera can set the focus and appropriate exposure for the shot automatically. When using a flash, face detection will also usually and automatically correct or remove the unwanted red-eye effect that can often occur when photographing people using a flash.

What is Smoothing?(SC)

Statistical technique for removal of short term irregularities in a time-series data to improve the accuracy of forecasts. It uses moving averages, or fits a curve to the plotted data points on a graph, and is a much simpler (although cruder) method than exponential smoothing.

What is the difference between ICR camera and ordinary camera??

IR cut camera will mostly help your daytime colors in your Place, but it also improves the black and white image at night as well, When the luminance is lower than the threshold set in the OSD menu, the camera will automatically switch to the other filter. However, the ordinary camera uses the same filter all day long.

What is the difference between Smart IPC and ordinary IPC?

Smart IPC™ provides complex equipment manufacturers, operators, and their maintenance service providers with a highly specialized, interactive Illustrated Parts Catalog (IPC) that is easily accessible via a web browser interface.

What is the maximum distance for PoE cable?

Cat6 cable is recommended for long POE runs. For passive POE you should use a 24V power supply. 24V passive POE will power an OM series AP up to about 50 meters or 100-150 feet. 48V 802.3af standard POE can usually go about 100 meters/300 feet.

What is the meaning of PoE indicator lights?

The SYS, ACT, and POE lights refer to: system status, network activity, and power over Ethernet. The lights in the image show that the router’s system is successfully powered on, that there is network activity, and that Power over Ethernet is not activated.

What is the problem about Depth of field?

Depth of field refers to the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance, although print size and viewing distance can also influence our perception of depth of field. This tutorial is designed to give a better intuitive and technical understanding for photography, and provides a depth of field calculator to show how it varies with your camera settings. The depth of field does not abruptly change from sharp to unsharp, but instead occurs as a gradual transition. In fact, everything immediately in front of or in back of the focusing distance begins to lose sharpness — even if this is not perceived by our eyes or by the resolution of the camera.

What is the transmit distance of wireless camera?

Wireless security camera systems from CCTV Camera Pros consist of wireless transmitter and receiver antennas and allow closed circuit cameras or IP security cameras to transmit a wireless signal using a 5.8 GHz signal up to 4 miles. These systems are used in situations where cable dredging is not practical or is cost prohibitive.

What are the common audio coding standards?

Some audio coding formats are documented by a detailed technical specification document known as an audio coding specification. Some such specifications are written and approved by standardization organizations as technical standards, and are thus known as anaudio coding standard. The term 'standard' is also sometimes used for de facto standards as well as formal standards.

What could be some common interfaces?

In Digital Video Broadcasting, the Common Interface is a technology which allows separation of conditional access functionality from digital receiver-decoder (Host) into a removable conditional-access module (CAM). It is also referenced as DVB-CI for Digital Video Broadcast - Common Interface. The host is responsible for tuning to pay TV channels and demodulation of the RF signal, while CAM is responsible for CA descrambling. The Common Interface allows them to communicate with each other

What is H.264+ ?

H.264 or MPEG-4 Part 10, Advanced Video Coding (MPEG-4 AVC) is a block-oriented motion-compensation-based video compression standard that is currently one of the most commonly used formats for the recording, compression, and distribution of video content.

What is Main stream/Sub stream?

Main Stream

This is the primary stream that affects data recorded to the hard disk drive and will directly determine your recording quality. The resolution denotes the image size and quality and is therefore very important and should not be overlooked. The frame rate (FPS - Frames per Second) denotes how many frames are captured each second, with more frames being captured resulting in a smoother, more fluent and higher quality recording - 25FPS = “Real Time”. A higher resolution and frame rate will look best however be aware that it will use up more storage space on the hard disk drive. Setting a higher FPS will also affect your internet bandwidth when viewing a live stream. Users with limited internet speeds may suffer when using higher settings. The bit rate affects both of these settings and is usually dictated by a combination of the above. Lowering the main stream settings is an effective way to increase available recording time.

Sub stream

The sub stream or extra stream is a second codec that runs alongside the main stream. This allows you to reduce outgoing internet bandwidth without sacrificing your direct recording quality. The sub stream is often exclusively used by smartphone applications to live stream however some smartphone applications do allow the user to choose the main stream too. Lowering the sub stream settings is often a common solution to no picture availability on a smartphone. Users with limited internet speeds may benefit most from this setting.

What is NVR?

A network video recorder (NVR) is a software program that records video in a digital format to a disk drive, USB flash drive, SD memory card or other mass storage device. An NVR contains no dedicated video capture hardware.

What is SVC?

SVC (Scalable Video Compression): Analyze the delay and packet loss statistics and self-adaptively extract the frames. Therefore the bit rate is reduced while the resolution is maintained. All the series of Vantage Professional IPCs support SVC.

What is Target Cropping?

Target Cropping: Cropping on third stream video. Available resolutions in

Target Cropping area include all options in third stream resolutions. Users can drag and select a certain area as the Target Cropping area on the image with the maximum resolution. The third stream resolution in Configuration->Video interface would be coherent with the Target Cropping area resolution. The pixel density in Target Cropping area is the same as that in maximum resolution image.

Target Cropping is not supported on products without third stream.

Which kind of IPC could access to cloud P2P?(

P2P stands for “Peer to Peer”. It is a technology that makes it simple to link the camera with a smartphone.

In camera speak, there is a UID (unique ID) assigned to each camera. When the smartphone app is opened, it pings the P2P server which in turn looks for the listed UIDs and where they are located. If the camera can be pinged, it shows as online, others are offline.

Once the cameras are reached, it creates a direct connection between the app and the camera. Just like the popular Bittorent peer to peer file sharing platform.

Peer to Peer based IP cameras

Why failed to create the file path when recording manually?

To solve this problem it is required to lower the custom level, and cancel protection mode in security level configuration in IE browser. Configuration comes into effect after rebooting.

Why is there howling sound during voice intercom?

A intercom has the mic and speaker close together. It eliminates acoustical feedback by using a simple "voice switch" or a complicated digital echo canceller circuit.
The voice switch turns off the speaker when the microphone hears a sound. Then it turns off the mic when a signal comes from the other end of the telephone line.
The digital echo canceller circuit makes a model of the phases and delays in the path between the mic and speaker then cancels it from the speaker's signal.
