How do IP Cameras work?

Use Single/Multiple Wired/Wireless Cameras. Monitor/Record on any computer locally. Remotely view any camera on the laptop, mobile phone or PDA.

Why do you need IP Cameras?

IP Camera systems are replacing Analog CCTV systems. You should use an IP Camera System if IP CCTV: You need install cameras on your site and record the activities locally on your premise. You want to install a single camera or multiple camera and monitor all the activity through a single screen and record all the video centrally for future viewing. You want flexibility in the time span you want to record your video/audio and an easy playback facility with date & time. Remote Surveillance: You want to monitor and control these cameras online from anywhere in the world. Not only that you want to receive audio and control the camera and other devices connected to the camera. Central Monitoring: You have multiple sites which you want to view from a central location. Wireless: The only recommended way for wireless video will be using IP Cameras. Exisiting LAN Network: If you have an existing LAN network then you don’t need to do any cabling. You can just plug your IP Camera’s into your existing network.

What is an IP Network Camera ?

A network camera (also referred to as IP camera) can be described as a camera and computer combined in one unit. It captures and transmits live images directly over an IP network, enabling authorized users to locally or remotely view, store, and manage video over standard IP-based network infrastructure. A network camera has its own IP address. It is connected to the network and has a built-in web server, FTP server, FTP client, e-mail client, alarm management, programmability, and much more. A network camera does not need to be connected to a PC; it operates independently and can be placed wherever there is an IP network connection. A Web camera, on the other hand, requires connection to a PC via a USB or IEEE1394 port and a PC to operate. In addition to video, a network camera also includes other functionalities and information being transported over the same network connection: i.e. video motion detection, audio, digital inputs and outputs (which can be used, for example, to trigger alarms or turn on lights), serial port(s) for serial data or control of pan/tilt/zoom mechanisms. Image buffers within a network camera can also save and send images that were collected before an alarm occurred.

Comparing a network and an analog camera

In recent years, network camera technology has caught up to the analog camera and now meets the same requirements and specifications. Network cameras even surpass the performance of analog cameras, by offering a number of advanced functions. In short, an analog camera is a one-directional signal carrier which terminates at the DVR and operator level, whereas a network camera is fully bi-directional, and integrates with and drives the rest of the system to a high degree in a distributed and scalable environment. A network camera communicates with several applications in parallel, to perform various tasks, such as detecting motion or sending different streams of video.
The IP Way – Livedarshan has made a switch from Analog to IP Cameras. A growing number of organizations, small and medium sized businesses, and home users throughout the world use Networked IP Surveillance now.  IP cameras are the way of the future.

What is POE ?

Power-over-Ethernet (PoE) or “Active Ethernet” eliminates the need to run 110/220 VAC power to IP Cameras and other devices on a wired LAN. Using Power-over-Ethernet system installers need to run only a single CAT5 Ethernet cable that carries both power and data to each device. This allows greater flexibility in the locating of IP Cameras and Network devices and significantly decreasing installation costs in many cases. All the cameras can then also be supported through a single UPS in case of power failure.

What is a Wireless IP Camera?

Wi-Fi cameras are a cross between IP cameras and regular Wireless Cameras. They mostly operate on Wifi 802.11 b/g networks. However, they do not need to be connected via a CAT 5 (LAN) Network cable (although they can if required). Instead, they are extrememly versatile and can be placed anywhere within a WiFi network at home or in the office and the data is transmitted wirelessly and digitally to your wireless access point, router or modem. It allows the flexibility of an IP camera as it allows videos to be streamed across the Internet while also offering the versatility of a Wireless installation. Our WiFi cameras come packaged with security software to allow motion detection (and automatic recording) as well as email alerts when movement is detected. WiFi cameras have a better operating range and are more reliable than standard wireless cameras. They can be used for setups from 10 meters to 50 km along with external equipment.

What are Advantages of a Network camera over a PC-based camera ?

With a built-in Web server, a network camera do not need a direct connection to a PC or any other hardware or software to capture and transfer images. It operates as a stand-alone unit and requires only a connection to the network.
 
True Network Camera
PC-based Camera
 
 Flexibility
Place it anywhere. You can connect the network camera to the network, modem, cell phone or wireless adapter.
The PC-attached camera needs to be within 3 meter (10 feet) of the PC.
 Functionality
Everything needed to stream live video over networks is included in the network camera.
You will need 3 components: Web camera, PC and PC software.
 Installation
You set the IP address and you’re up and running.
The installation of drivers and software on the PC is complicated.
 Ease of use
You can administer and view the images using a standard Web browser on any PC.
You will need specific software and remote administration will not be possible.

What is the advantage of a Network camera over an analog camera-based system?

 Network Camera-Based   System
Analog Camera-Based System
 Access
As open or closed access as needed. Remote access to live images and remote administration of a network camera are possible from anywhere using a standard Web browser on any PC.
Closed circuit. No possibility for remote access.
 Ease of use
You can administer and view the images remotely using a standard Web browser on any PC. – Images can be recorded on a hard disk, enabling easy search possibilities, easy storage and no image degradation or wear. – The hard disk can be located at a remote location for security purposes.
Remote administration or monitoring is not possible. – Images must be stored on video tape cassettes, which require constant changing and lots of storage space. The quality of recorded images deteriorate over time. – The video cassette recorder must be located near the camera. This could potentially enable unauthorized persons to have access to the video tape.
 Quality
Digital images do not lose quality in transmission or storage. A digital picture is created using Motion-JPEG. Once created, the image is free from degradation. Each frame within a video stream is sharp.
Image quality is lost when using long cables and the resolution of a magnetic tape is normally quite low. In addition, the quality of the recorded video deteriorates over time.
 System requirements
Everything needed to stream live video over networks is included in the network camera. Simply connect the network camera to a network. View, record and administer from any networked PC (located anywhere).
Connection to a coaxial cable, to a multiplexer, to a video or time lapse recorder, and to a locally placed CRT (cathode ray tube) monitor.
 Installation
Simply connect a network camera to the nearest network connection and assign an IP address.
Attach a coax cable to each and every camera and connect to the multiplexer.
 Cabling
network_cable One standard UTP (unshielded twisted pair) network cable can forward images from hundreds of network cameras simultaneously.
coax_cable One cable can transport video signals from only one camera at a time. If you have two cameras, you have to have two cables. This often means large cable trunks filled with thick and sensitive cables that are connected to a locally placed control room.
Scalability
Adding more network cameras to the system is easy.
Very difficult. Each analog camera requires its own cable. Image quality is lost when using long cables.
 Cost
A high quality network cable typically costs 50% less than a standard coaxial cable. A network cable can also support hundreds of network cameras and other devices. An IP-based network infrastructure is often already in place, which means the cost is reduced to only that of the network camera(s).
Expensive coaxial cables. A classic RG59 75 Ohms coaxial cable typically costs 50% percent more than a high quality network cable. In addition, more cable is required. Each analog camera requires its own cabling. High labor and maintenance demands, plus cost of the analog camera(s), video tape recorder and video tape cassettes.

What is Video Motion Detection (VMD)?

Video motion detection (VMD) is a way of defining activity in a scene by analyzing image data and differences in a series of images. The functionality can either be built-in into a network video product or made available with video management software. In-picture alarm programming allows you to define areas of a screen where you want to detect any visual changes.

VMD in DVR (Digital Video Recorder) systems

In such a system, cameras are connected to a DVR, which performs the VMD on each video stream. This allows the DVR to decrease the amount of recorded video, to prioritize recordings and to use motion in a specific area of the image as a search term when searching for events. The downside of this method is that performing VMD is a CPU intensive process and performing VMD on many channels puts a heavy strain on the DVR system.

VMD in network video systems

This alleviates the workload for any recording devices in the system and makes “event-driven surveillance” possible; that is, unless activity is detected in the scene, no video (or only video with low frame rate) is sent to the operator or recording system. If motion is detected, you may request a number of things to be done automatically; e.g. 1)Save images before, during and after the event (called pre- and post-alarm image buffering) 2)Start sending images for recording at specified destinations 3)Send alerts to specific individuals via e-mail or SMS to a mobile telephone, activate lights, turn alarm on or off, open or lock doors, control temperature levels etc. VMD data with information about the activity can also be included in the video stream to simplify activity searches in recorded material. Advantages of local VMD in the “endpoint” (network camera and video server compared with systems using central analyzing such as DVRs)
– Conserves bandwidth
– Reduces CPU load on recording server
– Saves storage space
– The camera can interact with others systems using I/O Ports (for example triggering alarms)

Can I use IP cameras with a dialup Internet account?

You can view live video from a dialup Internet account. You can use the wireless reliance data card or any other Wireless Data card to view the video live from your laptop/computer. However you cannot upload video from a dialup Internet account.

What is the difference between "static" and "dynamic" IP addresses?

A “Static” IP address is similar to your home telephone number. Your Internet provider assigns you an IP address that remains with you for the duration of your account. A static IP address also means that your Internet Service Provider (ISP) designates and maintains your connection regardless of the time you actually use it. This type of connection is more common with DSL access.
A “Dynamic” IP address system assigns you a new IP address each time you log on to your Internet account. If you stay connected 24 hours a day, the IP address will periodically be renewed (changed.) This method frees up IP addresses that are not in use for the Internet provider. Today, more and more ISP’s are changing to this system.You can use a free Dyndns service to have a static name which automatically maps to the changed IP.This name can be programmed into an IP Camera.

How many days of Video Recording can I have?

You can decide how many days of video you want to record at the onset. Accordingly we can plan the Harddrive space required by you to record video. There is no limit to the number of days you can record. You can either set the software to automatically delete the recorded video if the hard-drive is full and recycle video or you can stop the recording once the hard drive is full. Video can also be backed up on another hard-drive , CD or DVD for future reference.
