Please follow the below steps to connect your camera wirelessly with Wi-Fi Protected Setup (WPS):

Note: If you haven't done so, it is highly recommended that you use the setup wizard for your camera first for initial setup and registration with mydlink service.

Step 1: Press the WPS button on your camera for 3 seconds. The WPS LED on your camera should start blinking blue.

Step 2: Within 60 seconds, press the WPS button of the router that you want to connect.

Step 3: The WPS LED on your camera will automatically configure its wireless settings, and the WPS LED will turn solid blue, then your camera will reboot and connect to your wireless network.

Note: If your router does not have a physical WPS button, you may need to activate WPS through its web interface. Refer to your router's manual for more details.

If black screen appears in monitoring picture, please check whether the video signal of video server is normal or not.

If the selection of N systematical and P systematical is incorrect, the image will be black and white. 

If no image after installation, please check the power supply and make sure the video cable is workable.

No, because under strong light conditions is dangerous for the sensor it will harm.

IP surveillance technology becomes the new trend in security & protection industry. Nowadays, it's so convenient to buy IP surveillance equipment for ultra HD video surveillance system whatever for monitoring residential or business. Unlike the traditional cctv system, IP surveillance equipment rely on network for video transmission. Herein we provide some useful information about the connection of IP camera and NVR.

use IPC::System::Simple qw(capture); and then use the "capture()" command just like you'd use backticks. If there's an error, it will die with a detailed description of what went wrong.

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.

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.

The IPC Action Plan lays out the strategic framework and road map to achieve clear and measurable results in the next three years. The IPC Action Plan interlinks global and regional activities with associated budgets to support the implementation of the IPC in the 51 targeted countries. It is also the basis for the Programme's performance monitoring system, which enables to translate it into tangible outcomes.

The IPC focus action areas (2014-2018) are presented in the following section. Within the overall framework,Communication and Outreach is a cross-cutting area to leverage the IPC Action Plan results at all levels.

The protocol, baud rate, or address is incorrect. Please change the protocol, baud rate, and address in the web management system to those used by the PTZ or dome.

The signal cable is not properly connected. Please check the signal strength and connect the signal cable properly. 

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.

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.

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.

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.

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.

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.

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.

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.

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.

 

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.

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.

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.

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.

Manufacturing tolerances often result in subtle mismatches between camera bodies and lenses, resulting in poor autofocus performance. This can cause your images to be softer than they should be.

8. Screw the CS-mount lens clockwise back. Unscrew a little and plug the CS-mount lens cable to the socket. Repeat this till the IP camera display the image properly.

 9. Once the IP camera has detected the image, use the L-type hex wrench slightly secure bolt underneath the IP camera. [Note] Do not fully tighten bolt underneath the IP camera for it may damage the CS-mount ring.

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.

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.

The wireless security camera systems are new high performance digital wireless security camera transmission systems. These are our most popular and most recommended systems. These wireless systems offer exceptional video data transmission using 5.8Ghz frequency. They are made for long distance outdoor use with a direct line of sight between the transmitting and receiving antennas. Click here to read more about wireless camera systems or scroll down lower on this page. We also have some images available to view here of real wireless installations

Independent of main stream and sub stream, supported resolutions include all resolutions of main stream and sub stream. The encoding parameters can be configured individually. Given the network conditions and the terminal display capabilities, third streams is optional for remote live view: HD with full frame rate, HD with low frame rate and SD with full frame rate, respectively. Together with SVC and target cropping, third stream provides better live view performance. Also third stream offers users an alternative to select data streams.

Television lines (TVL) is a specification of an analog camera's or monitors's horizontal resolution power. It is alternatively known as Lines of Horizontal Resolution (LoHR) or lines of resolution. The TVL is one of the most important resolution measures in a video system.

The IPC analysis process by digitizing the IPC tools needed to implement the IPC four core functions: Building Technical Consensus; Classifying Severity and Causes; Communicating for Action; and Quality Assurance.  the  mirror  is to increase transparency and accountability, and enables historical review of IPC analyses conducted at national and regional levels.    

In this case Verify the file path locations and Ensure the paths exist, are correct, and Log Server has permission to write to them.  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.

If you don't hear sound when playing files:
• There may be problems with the particular file you are playing,
• There may be problems with your system's sound configuration, or
• The sound card drivers are out-of-date.

To resolve this problem, you may need to check and adjust the system volume, play other files, check the sound card for device conflicts, close other programs, or update your sound card drivers.

A power supply (PSU) is an electronic device that supplies electric energy to an electrical load. The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters. Some power supplies are discrete, stand-alone devices, whereas others are built into larger devices along with their loads. Examples of the latter include power supplies found in desktop computers and consumer electronics devices.

1. DVR upgrade errors caused by system software are corrupted.

2. DVR boards fault, contact the vendor maintenance.

3. A hard disk malfunction, replace the hard disk.

To have multicast routing in a working configuration, you must enter each interface and configure the PIM on those interfaces. To enable PIM on an interface, you use the ip pim command, which accepts either a dense-mode or sparse-mode option.

To configure channel-zero encoding:

    1. Access the Live View Settings interface. Menu > Configuration > Live View.

    2. Click the Channel-Zero Encoding tab.

    3. Select the Enable Channel Zero Encoding checkbox.

    4. Configure the Frame Rate, Max. Bitrate Mode, and Max. Bitrate.

    5. Click the Apply button to save the settings.

Use this tool to determine how much hard drive storage space you will need for your network IP surveillance system.

Note: Additional factors may influence an NVR’s hard drive storage capacity as well as the number of days the NVR will store information. Common factors that affect the NVR’s storage capacity include: video compression (codec), resolution, and motion detection recording.

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.

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

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.

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.

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.

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.

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.

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

• Linking to the camera can be done in a couple of minutes.
• QR code scanning for convenience in linking.
• Complete protections and privacy with encrypted video streaming
• As server pings the camera, its easy to know when the camera is offline or unreachable.

In this case Verify the file path locations and Ensure the paths exist, are correct, and Log Server has permission to write to them.  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.

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.

If your dvr/nvr cannot find hdd .in this case firstly you check your hardware connection Check the master/slave jumpers and the cable/power connections. After that proper format hard disk's.
