In today's world, an IP surveillance camera system may be the smart solution to security issues as terrorist becomes more sophisticated in devising new methods in carrying out there attack more people are turning to video surveillance to help identify threat and monitor events. In today article we will analyze the advantage of this equipments and how implementing it can proffer solutions. In a home, business, or other establishment. Compared to traditional security cameras, IP or Internet protocol has its advantages. As more and more people switch to IP surveillance system as against the old CCTV, ease of installation and higher resolution of video, CCTV (closed circuit television) and DVR methods are quickly becoming obsolete because IP allows business owner, law enforcement officers, etc to view video from anywhere with an Internet or network connection. With a wide market out there, some business owners may feel a little overwhelmed, but by configuring some key simple features one can relax and be rest assured that the desired solution will be achieved.
What is an IP Camera
An IP camera captures and sends video footage over an IP network, allowing users to view, record, store, and manage their video surveillance images either locally or remotely over the network infrastructure. The camera can be placed wherever there's an IP network connection. It has its own IP address and unlike a webcam, doesn't require a connection to a PC in order to operate.
Along with streaming video footage, network cameras can include a number of additional functionalities, such as pan/tilt/zoom operation, motion detection, audio surveillance, integration with alarms and other security systems, automated alerts, intelligent video analytics, and much more. Many IP cameras can also send multiple streams of video, using different compression technologies for live viewing and archiving.
IP cameras offer flexible installation, ease of use, higher-quality images, stability, and scalability as new cameras can be added to the network at any time.
Types of IP Cameras
The variety of network camera models available from: Axis, Panasonic, Sony & Mobotix, allows users to install video security solutions fit for any surveillance application. Here are some of the more common IP camera types.
Fixed IP Cameras
Fixed network cameras are the ideal choice for those who wish to monitor a very specific area and also intend to have the camera, and the direction it's pointing, clearly visible. Once the camera is focused on a location, it's set to view only that area. Most fixed cameras support interchangeable lenses and housings for various environments.
Fixed Dome Cameras
Fixed dome cameras are often small and discreet, with a fixed camera installed inside a dome housing. The camera can be pointed in any direction and then set in place to target a specific area. Fixed domes can provide unobtrusive surveillance, and the housing helps to conceal which direction the camera is aiming.
Unlike fixed cameras, PTZ network cameras allow the user to control pan, tilt, and zoom functions in order to monitor wider areas and zero on specific individuals, objects, or activity. In a retail setting, for instance, surveillance operators can control a PTZ camera to follow a suspected shoplifter. Most PTZ cameras offer both manual and automatic PTZ control.
Network Dome Cameras
The advantage of network dome cameras over PTZ cameras and fixed IP cameras is they can pan up to 360 degrees and support continuous "guard tour or patrol" operation. Guard tour / patrol functionality enables a single network dome camera to automatically move between presets in order to cover large areas that would typically require multiple fixed cameras.
Video motion detection is a useful tool that allows you to program your network camera to begin recording, and perform other functions such as sending automated email alerts, when movement is detected within a scene. The functionality comes either built-in with your IP camera, or through video management software.
There are a number of advantages to using motion detection. Since you can limit recording to situations when activity is taking place, motion detection helps to conserve bandwidth, saves storage space, reduces CPU load on recording servers, and also allows for integration with other systems such as alarms and access control systems. The system can be set up so that unless movement is detected, no video is being recorded. It can also be programmed to send video at a low frame-rate until motion is perceived.
A number of actions can be triggered using motion detection. Examples include: saving images before or after an event, delivering video images to specific locations for recording or monitoring, sending email and phone alerts, activating door locks and lights, sounding alarms, and more.
Many IP camera models offer audio support. Some feature built-in microphones that allow operators to listen in on areas under surveillance, while others provide for two-way audio communication using a microphone and external speaker. Audio is transmitted across your network the same way video footage is, so setting up a surveillance system that captures audio is as simple as hooking up your cameras. Using either a built-in or external microphone, the camera captures the audio, integrates it into the video stream, and streams it over the network for monitoring and recording.
Just like network video, audio footage can be accessed from remote locations. Users can monitor and listen in on areas within range of the cameras, and with a two-way audio setup can even talk to those under the camera's watch. The cameras can also be programmed to deliver recorded messages informing possible perpetrators that they're under watch. Another useful function is audio detection. This is the process where a network camera is set to record when the audio level reaches a certain mark. Audio detection can also be used to trigger alarms and send alerts.
Video analytics are sophisticated applications and software algorithms that perform analysis of surveillance video as it's being captured. While there are many potential benefits to using video analytics, the main aim of the technology is to enable surveillance systems to not just capture video footage for post-event investigation, but to actually detect suspicious activity as it happens. In that sense, video analytics serve to provide a form of preventative surveillance.
Some of the more common surveillance applications that fall under the video analytics umbrella include advanced motion detection, facial recognition, behavioral recognition, audio detection, license plate recognition, and the ability to detect very specific events such as a person leaving behind an object, or acts of graffiti and vandalism.
Video analytics can either be built into the network camera, or work as part of a video management software platform. With the introduction of megapixel IP cameras, this technology has become increasingly popular and effective. While the technology is applicable to a range of applications, it's most commonly used for surveillance in high-security locations such as banks, airports, and government facilities. Some banks, for instance, now use facial recognition to identify individuals suspected of check fraud and other criminal activities.
Since the technology is relatively new, the various impacts of video analytics are still being weighed. As the technology improves, and more options become available, we can expect to see different forms of video analytics used for everything from preventing crime and speeding up response times, to reducing false alarms and optimizing video storage space.
Power over Ethernet (PoE)
Power over Ethernet (or PoE) is a technology that allows LAN-enabled devices, such as network cameras and IP telephones, to be powered over an IP network infrastructure using standard Ethernet cabling. In the case of an IP-based surveillance system featuring PoE cameras, each individual camera transmits data and receives power via a single Ethernet cable, eliminating the need for complicated and expensive cabling because the system operates along an existing network.
Power over Ethernet allows for flexible camera installation as cameras can be placed in areas where power outlets aren't readily available. This means users can actually install the cameras where they're needed, not just where the AC sockets are. Power is supplied directly from the data ports that the cameras and other network devices are connected to. Users can also install Wireless LAN access points for even greater flexibility.
Another benefit of PoE technology is it enables easy installation of UPS (uninterruptible power supplies) for video surveillance applications requiring 24-hour surveillance that will continue even during power outages.
Existing wireless mesh network can integrate this solution to cover a vast area providing online real-time live video surveillance feed in high resolution, wireless mesh node from Firetide works seamlessly in providingsolution.Wireless network cameras are primarily used in situations where the installation of extra cabling in a building could cause damage, or in locations where cameras need to be frequently repositioned. Basically, we're talking about video surveillance installations where a wired solution is impractical, or installations requiring the mobility that a wireless solution provides.
The most common modes of wireless communication are wireless LANs and wireless bridges. A wireless LAN is just what it sounds like – a wireless local area network. Wireless LANS are typically setup indoors and cover short distances. The standards for this type of wireless network are usually well defined so products from different vendors can operate together on the same network.
Wireless bridges are used to connect buildings or multiple sites together using a point-to-point data link that allows data to travel long distances at high speeds.
Video Surveillance Management
The network camera is only one piece of the IP surveillance puzzle. Because network cameras transmit data digitally over an IP network, new worlds are opened up in terms of video management. Users can access their cameras from anywhere using a standard web browser, and are provided with advanced tools for monitoring and recording with IP video management software
Video management software like Milestone, is a key component of any video surveillance solution. It's the software that provides the tools for monitoring and analyzing surveillance footage, as well as recording. While a standard web browser often allows for remote viewing, dedicated video management software is required for viewing and managing multiple cameras at once.
The most basic IP video software provides live viewing, recording, and retrieving of video footage. More advanced NVR software platforms offer simultaneous viewing of multiple cameras, and multiple recording modes (including continuous, scheduled, and triggered recording). Other features may include the ability to handle large image files with high frame rates, fast search capabilities, pan/tilt/zoom control, audio support, and remote access via web browser as well as cell phones and other handheld devices. Some software programs also support intelligent surveillance using sophisticated video analytics such as facial recognition and advanced motion detection.
Digital Input & Output
Digital input and output ports are available in various network video products, including many IP camera models. Digital input/outputs (or digital I/Os) allow you to connect the camera to external devices such as motion and sound detectors, smoke detectors, doorbells and door locks, glass-break detectors, and of course alarm systems. Communication between the network devices can be managed remotely from a PC with network access, or automatically using the camera's built-in features.
Digital I/Os can help to limit video transmissions so that video is sent over the network only when one of the network devices is triggered by an event such as motion detection, audio level, or the opening of a door. This process optimizes bandwidth usage and conserves storage space. Digital I/Os also allow for the automatic triggering of specific actions such as capturing and saving images, sending automated alerts via email or phone, and activating lights, alarms, and door locks.
The main function of an IP camera's input port is to support devices such as sensors and detectors, while the output port allows the camera to trigger external devices and activate specific actions, for instance sirens, alarms, and event-
Security Camera Housings
A variety of IP camera housings are available to ease installation and to help protect network cameras from tampering, vandalism, and harsh conditions such as extreme cold, humidity, dust, moisture, and more.
For IP cameras placed in vulnerable areas, vandal-proof housings are an excellent option. They're available for both indoor and outdoor surveillance applications, and typically feature sturdy metal construction, an impact-resistant dome or window, and tamper-resistant screws.
Fixed IP Camera Housings
Designed to offer protection for fixed network cameras, these housings are available for indoor and outdoor surveillance setups. They work to protect and cover network cameras, and come in various forms for mounting on ceilings and walls.
Outdoor network cameras housings are built to be weatherproof, resistant to moisture, and sometimes even feature built-in fans and heaters for both cold and hot environments. The housings come in different sizes to handle different camera types such as fixed IP cameras and PTZ domes, and are also available in vandal-proof versions for hostile environments.
As with any video surveillance system, privacy and security are important factors to consider when setting up an IP-based video solution. Users want to be assured that no one can tap into their video feeds. Those concerns are understandable, but with IP network cameras, it’s quite easy to protect your files from unauthorized viewing and tampering. In most cases, the network camera encrypts the surveillance video before sending it over the network. This helps to ensure that only authorized viewers can access the camera feeds. Most systems also include password protection and different levels of authentication that work to prevent hacking and outside access.
Benefits of Network Video
IP-based video surveillance has improved the effectiveness of video security by leaps and bounds over the analog CCTV equipment we've grown so accustomed to over the years. Today's IP video surveillance solutions use an IP network, rather than complicated cabling setups, as the backbone for delivering information. This allows for flexible, cost-effective installation, remote video monitoring, improved storage, and a host of other benefits.
Remote Video Monitoring
With an IP-based surveillance system, users can view live network camera feeds in real-time from any computer with Internet access. Network cameras can capture and transmit high-quality video images over any IP network or the Internet, where the footage can be viewed remotely using a computer or, in some cases, cell phones and other handheld devices. Additionally, the recorded surveillance footage can be stored at remote locations.
Expanding a network surveillance system is as simple as connecting additional IP cameras to the IP network. IP cameras can be placed anywhere along the network, and there's no need for expensive and complicated cabling. Simply connect the camera like you would any other network device.
Improved Storage Capabilities
Since network cameras capture digital video images, large amounts of footage can be stored on servers and network video recorders, where archived video can be quickly accessed and searched. Compare this type of setup to analog systems where video was stored on VHS cassette tapes, and it's easy to see the benefits of a digital surveillance system.
Network Camera Considerations
A network camera is essentially a camera and computer in one. These cameras capture and transmit video across an IP network, which allows for both local and remote viewing and video management. IP cameras connect to your existing IP network just like any other network device. The advantages of network cameras over analog equipment include remote monitoring, digital storage, cost-effective installation, flexibility, and scalability should you need to install additional cameras down the road. IP cameras are available in countless makes and models offering limitless surveillance possibilities. Choosing the right network camera depends on your security need and area of interest above what you want to accomplish.
