There are many details to consider when the declaration of the corresponding system of CCTV cameras. Professional Video Surveillance is not an economic effort and a budget presentation and the best system should be considered. This guide will help beginners review CCTV coppercamera and recording system for their CCTV and video surveillance needs.
The first task of a successful CCTV project, CCTV is the key to clarify the objectives.
o How many cameras are required?
o What are the main FOV (Field of view (s))?
o What are the entry requirements?
o What are the lighting conditions at each location camera?
o How should I use for monitoring live video or other video screen?
or untilVideo files need to maintain?
Camera There are special cameras to be selected by the field of view, lights, and the mounting position of the camera. There is no such thing as a one size in the successful CCTV project. It 'important to see that everywhere camera and the camera is more suitable for the selected location.
Answer the following questions:
Within or without the O?
or light (during day and night)?
Or Installationelse?
Indoor Dome Camera
The inner dome camera is used in 90% of the total in the programs. It comes in a variety of configurations, including standard color, day / night, and infrared versions. Can be mounted on a horizontal or vertical, but is typical ceiling mounted. Choice of Camera Lens Dome programs can reduce its use in some as little more than a 20mm video lens. 'D Indoor Dome is a primary choice in camerapositions.
Digital Camera
A camera box is a standard camera can be mounted alone or in a room. The camera uses a separate box lens that screws onto the surface and provides flexibility for different requirements FOV and sold without a lens. An auto-iris lens, a small cable that connects to the camera for iris control in various light conditions.
Outside the Cathedral
Outside the cathedral is usually difficult to draw tag vandal intestine, which offerssame versatility in a variety of lens options. Day / night, with no dome cameras are widely used in applications requiring input and output with limited lighting at night.
Day / Night Camera
The day / night camera is the best choice for low light conditions. The cameras are standard color during the day, day / night shifts or mechanically from a digital camera on a low-lux mode B / W.
Infrared
During conditions of no-light, infrared cameraswith infrared illumination of the FOF and monitor areas without electricity. Te IR LEDs lit and the camera automatically turns B & W low lux camera mode with views of total darkness.
PTZ Camera
Pan-Tilt-Zoom lets you see in all directions and the optical zoom if necessary. PTZ cameras including standard color, day / night mode, and some IR PTZ cameras have been introduced recently. The operator CCTV PTZFOVS different cameras to automatically rotate. Options include Auto-tracking applications that dynamically objects in defined areas.
About Room Technology
Sony CCD is the dominant element in the video security cameras now. Sony makes some cameras, but just the CCD market. Do not think that Sony makes the camera as "Sony 1 / 3" Super HAD Camera "as many manufacturers advertise their cameras, the camera has a Sony CCD sensor. But the camera is Sonyand almost every camera brand there. Important factors affecting the quality of the lens, and vari-focal auto-iris capability, the quality of the camera housing or enclosure, and the optical lens is the difference between a professional CCTV camera.

Camera Enclosure
Box cameras can be mounted in a variety of fields. Outside the camps in cold climates need a block heater / fan that keeps frost and condensation on the lens and the camera. Heater / fan are commonly 24VAC and should be considered in the choice of power supply of the CCTV system.
Location Room
Camera mounting position is crucial for successCCTV project. Cameras should be mounted as close as possible to the visual field is necessary, and as the camera to the subject, the better identification of the subject will be. Proper lens selection than the location of the camera and the required FOV is critical to image quality.
Digital Video Recorder
DVRs are an important part of the success of any draft resolution closed circuit. Video gets bigger, faster recording acceleratedvideo and data compression is to reduce the file size of video data. terabytes of storage is increasingly common in many CCTV applications. Network or remote control of CCTV video is standard in all professional DVRs on the market in 2007 and video distribution over LAN, WAN and Internet, DVR a new market outside of video security, known as monitoring systems' business activity as a management company to monitor specified key questions, 24 hoursOne day. Not only a security video recorder, DVR, is a management tool for remote control applications.
To correct for any DVR application to select the following questions must be answered.
o How many channels (cameras)?
or that the recording speed is needed?
o How long Size) for storing video files (Hard Drive?
o What features are important to the program?
o Where will DVR systemlocated?
or remote control requirements?
When choosing the right DVR for your CCTV application, ensure that the required quantity cameras now and in the next 24 months supply. DVRs are available in 4, 8, 9 and 16 channel stage and this election is critical because adding cameras above the DVR channels available will add a DVR, not just additional channels. DVR systems in large plants are divided into units of 16 channels and monitored andcontrolled by a central management system.
The speed of the investigations are critical to many CCTV applications. 30 fps (frames per second) are considered as real-time video, to obtain 480 fps 30 fps for the application of 16 channels and 240fps for 8 channels are required. CCTV provides many applications in real time (30 fps) live viewing of video channels and 7-15 fps for recorded files. And 'acceptable to 7-15 fps for recorded files in many programs, butDVR technology has driven real-time video to the masses and 30 fps recording will soon be standard recording for all channels available today.
File preservation of view is much easier and profitable in 2007 than in the past. level of DVR storage terabytes are common and run faster and more reliable service. Storage of video data file can be managed by corporate IT departments, like all critical enterprise data and storage network drive are common. All top DVRs have USB ports for external storage devices and video servers are common LAN. A key component of any DVR system is the ability to access video files. The DVR software manufacturers are owned by the DVR and the ability to receive files in chronological order or according to certain security events is essential for the product DVR.
Standalone DVR PC-based vs.
Standalone DVR, most ofvideo equipment on the market sold for 2006. DVR-based computer has become increasingly popular due to the cost and features provide the latest generation of DVR cards on the market in 2007. Windows XP PC, is that the reliability and performance in today's DVR systems, security systems, required for mission critical video. The DVR PC-based open systems architecture can be easily integrated into the corporate network and technology upgradescomponent level. Software upgrades and hard drive storage additions are far cheaper than the DVR ownership. Standalone DVR integrated recording systems usually work with the Linux operating system. The DVRs are widely used in independent security retail sites and provide reliable video recording for 4-16 channels. Most DVRs on the market offer network remote access and CD-R / W archiving.Computer-based DVR systems are reliable, fast, and has many advanced applications not availableindependent systems.
Video Compression
MPEG4 and H.264 video compression elections in 2007. In short, a good MPEG4 and H.264 is better. The key to video compression is the resolution and video size. A high-resolution video files are monster size files and video compression for storage and streaming is critical for all video applications. Major advances in video compression will be seen in 2007and H.264, the codec choice for DVR manufacturers.
H.264
It uses the latest innovations in video compression technology to provide high-quality video at high resolution of the smallest amount of video data is necessary. Smaller files and save storage costs of bandwidth than previous generations of video codecs. H.264 delivers the same quality as MPEG-2 to third to half the data rate and up to four times the size of MPEG-4 Part 2 ofsame transmission rate. H.264 is used in the video-art equipment for high-definition video equipment, DVD and Blu-ray should be considered for any professional CCTV project.
Access to the Network and Remote Viewing
Network access is the ability to remotely monitor a video server network, WAN or Internet. A very important question for any DVR system is the ability to monitor and direct access to recordings remotely. Most days a DVR LAN RJ45connection that allows video recorder to be connected to the LAN like any other computer in the office.
DVR Advanced Features
Many CCTV systems are available with advanced security and special software to improve security. These include:
or object when
O POS Integration
O PTZ Auto-Tracking
O Face
or integration of access control
Act V cables and system layout
When choosing a DVR Locationoptimal position for the DVR system, consider the access area of centralized management and security of the area. DVR is the heart of the CCTV system and to be protected to ensure it is safe from theft or damage. If security problems include the theft of the DVR component, all the tests, conducted under the arm of the thief. And the thieves know this, then set the DVR system is in a "lock-box or a place of safety.
Camera power supply
Everyprofessional camera is either 12VDC or 24VAC. Both power options are acceptable and some CCTV systems require both. Central power supplies are available in 4,8,16 and most channels.
Cable Options
Traditional video cable is RG59 coax cable. Conjunction double cable is generally used to attract RG59U with a pair of wire 18 meters of the camera may require. The two cables can run a cable to each camera for both video andflow.
Cat-5 Options
UTP (twisted pair) cables are still popular with Cat-5e/Cat-6 cables used in networks. CAT cabling is lighter and less expensive coaxial cable and connectors, video balun to match the impedance of the country. Coax and UTP connections to1000 feet are acceptable. A balun is used for impedance on Cat-5 connections on the DVR and camera connections to adapt.
