This CCTV Buyer\'s Guide provides a comprehensive overview of the successful deployment of video surveillance camera systems in your business or home.
This guide contains information that helps design a video surveillance system, selects products that best meet the requirements of the CCTV system, and helps you make critical installation decisions that save time and money.
This information comes from the deployment of 100 CCTV systems and is collected from CCTV call centers that answer questions from commercial and residential customers.
This guide combines data from past CTV projects and provides a head for readers
Starting with a successful CCTV project, there are many details to consider when specifying the correct CCTV camera system.
Professional video surveillance is not a cheap job and should outline the budget and consider the system as good as possible.
This guide will help CCTV novice buyers review the camera and recording system according to their CCTV and video surveillance requirements.
The first task of a successful CCTV project is to outline the key objectives of CCTV.
O how many cameras are needed?
O What is the key FoV (Field of View(s))?
O What is the recording requirement?
O What are the lighting conditions for each camera position?
O where do I need live video surveillance or a second one?
O how long does it take to keep video files?
Depending on the field of view, lighting conditions and the installation position of the camera, a specific camera needs to be selected.
There is no such thing --
In the successful CCTV project, the size is very suitable.
It is important to note each camera position and select the camera that best suits that position.
Answer these questions: indoor or outdoor?
O Lighting conditions (
Day and night)?
Installation location?
The indoor dome camera is used in an indoor application of 90%.
It comes in a variety of configurations including standard color, day/night, and infrared versions.
It can be mounted on a horizontal or vertical surface, but usually on a ceiling.
Lens options on Dome cameras may limit their use in certain applications, such as requiring more than 20mm video lenses.
Dome cameras are the main choice for indoor cameras.
Box CameraA box camera is a standard camera that can be installed separately or installed in the enclosure.
The box camera uses a separate lens that is screwed to the front surface, providing flexibility for different field of view requirements and is sold without a lens. An auto-
Under various lighting conditions, the iris lens will have a small cable connected to the camera for iris control.
The Outdoor Dome camera is usually a hard shell breaker-
The roof housing provides the same versatility in a variety of lens options.
During the day/night, Outdoor Dome cameras are common in the application of limited entry and exit points for night lighting.
Day/night camera is the best option for low
Light conditions.
In daytime conditions, the camera is the standard color and the camera will digitally switch the machine to a low color during the day/nightlux B/W mode.
No infrared camera
In light conditions, the infrared camera provides infrared lighting of the FoF, allowing the monitoring of areas without light.
Te IR LEDs light up automatically and the camera switches to B/W low
Lux mode provides camera views in full darkness. PTZ CameraPan-Tilt-
The zoom camera provides the ability to view in all directions and zoom in optical as needed.
The PTZ camera also includes standard color, day/night mode and has recently introduced some ir ptz cameras.
CCTV operators can set the PTZ camera to automatically rotate to a different fov.
Options include automatic
Tracking applications that dynamically track objects in defined areas.
With regard to camera technology, Sony CCDs is the dominant video element in today\'s security cameras.
Sony rarely makes cameras, but they have the CCD market.
Don\'t think Sony has made a camera known as the \"Sony 1/3 Super camera\" because many suppliers are promoting their cameras.
The camera has a Sony CCD, but the camera is not a Sony one and can be a camera of almost any brand.
Important factors in lens qualityfocal and auto-
Iris capability, the quality of the camera housing or housing, and the lens optics are the differences between professional CCTV cameras.
Facts about the camera: If you buy a $80 camera, you get a $80 perspective.
480 TVL should be the minimum requirement for any professional CCTV project.
The position of the camera and the correct lens are the key to high quality video capture. The camera loves the light, the thief hates the light!
Add lighting wherever it may be installed in various enclosures.
An outdoor enclosure in a cold climate should include a heater/blower to prevent frost and condensation on the lens and camera.
The heater/blower is usually 24VAC and should be considered when selecting a CCTV power supply system.
Camera installation location is critical to the success of the CCTV project.
The camera should be as close as possible to the desired field of view, and the closer the camera is to the subject, the better the subject\'s identification.
With respect to the camera position and the desired field of view, proper lens selection is critical for high quality pictures.
Digital video recording is an important part of any successful CCTV project.
Video resolution is getting bigger and faster, and video data compression is reducing the size of video data files.
TeraByte storage capacity has become more and more common in many CCTV applications.
The network or remote monitoring of CCTV video is the standard of all professional dvr on the market in 2007. It is also a new market for local area network, wide area network and network to provide DVR with a video security, called business system monitoring, allow management to monitor specific key business areas 24 hours a day.
DVR is no longer just a security video recorder, it has become a commercial tool for remote monitoring application management.
In order to select the correct DVR for any application, the following questions need to be answered.
How many channels are there (cameras)?
O what speed does the record need?
O video file retention time (Hard disk size)?
O which features are important to the app?
Where will the DVR system be located?
O remote monitoring requirements?
When choosing the right DVR for your CCTV app, make sure you are determining the number of cameras you need now and within the next 24 months.
The DVR has 4, 8, 9, and 16 channel increments, and this option is critical because adding the camera above the available DVR channel requires an additional DVR, not just an additional channel.
The DVR system in large equipment is divided into 16 channel units and monitored and managed through the central management system.
Recording speed is critical for many CCTV applications. 30 fps (
Number of frames per second)
Considered true.
Therefore, in order to get 30 fps of the application, 480 fps of 16 channels and fps of 8 channels are required.
Many CCTV apps will provide realtime (30 fps)
Live viewing of video channels and 7-
15 fps of the record file.
7-is acceptable.
In many applications, the fps of the recorded file is 15 fps, but the technology in the DVR system drives real-time
Mass time video and 30 fps recording will soon become the standard recording rate for all channels today.
The storage of Vide files in 2007 is much easier and more cost-effective than ever before.
Tb-level storage is common and drives become faster and more reliable.
Since any business-critical data and network drive archiving is common, retention of video data files can be managed by the company\'s IT department.
All top DVR systems have USB ports for external storage devices and LAN
Video-based servers are common.
A key component of any DVR system is the ability to access video files.
The software provided by DVR manufacturers is the proprietary software for DVR devices, and the ability to retrieve files in chronological order or based on certain security events is critical to DVR products. PC-Based vs.
As of 2006, the independent DVRsStandalone DVR system is the majority of the video recorders sold on the market. Computer-
Due to the cost and functionality of the latest generation of DVR cards on the market in 2007, DVR-based DVRs are becoming more and more popular.
Windows xp pc computers provide the reliability and performance of today\'s DVR systems required for mission-critical video security systems.
Open architecture for PC-
The base-based system allows easy integration into the enterprise LAN, with technology upgrades at the component level.
Compared to Proprietary DVR systems, the cost of software upgrades and hard disk storage is much lower.
Independent dvr is usually an embedded recording system running under Linux operating system.
Independent dvr is widely used in retail security places, which is 4-16 channels.
Most dvr on the market offers network remote access and cd r/W archiving. Computer-
DVR-based systems are reliable, fast, and there are many advanced applications that cannot be found on stand-alone systems.
Video compression mpeg 4 and H.
264 is the first choice for video compression in 2007.
To sum up, mpeg 4 is good, H. 264 is better.
The key to video compression is the resolution and size of the video.
High resolution video files are monster-sized files, and video compression for storage and streaming is critical to any video application.
The main progress of video compression will be in 2007 and H.
For DVR manufacturers, 264 will be the preferred codec. H.
264 this uses the latest innovations in video compression technology to provide high resolution video quality from the minimum amount of video data required.
Smaller files will save bandwidth and storage costs compared to previous generations of video codecs. H.
264 provide the same quality as MPEG
2 at the third to half data rate, the frame size is four times that of MPEG-
4 The second part at the same data rate. H.
264 latest video equipment for high definition video equipment, BluRay DVDs, any professional CCTV project should be considered.
Network access and remote viewing network access is the ability to remotely monitor video servers via LAN, WAN or internet.
A very important application for any DVR system is the ability to monitor real-time and access recordings through remote access.
Today, most dvr have a LAN RJ45 connection that allows the VCR to connect to the LAN like any other PC in the office.
Advanced DVR features many CCTV systems release professional software with advanced security and security enhancements.
These include: o object count o POS integration o PTZ Auto
When selecting the best location for the DVR system, consider the access of the area to achieve centralized control and security of the area.
The DVR is at the heart of the CCTV system and should be protected as needed to ensure it is protected from theft or damage.
If security holes include stolen parts, all evidence will be taken away under the thief\'s arm.
The thief knows this, so make sure the system is locked
Case or proper safety area.
Each professional camera requires a camera power supply of 12VDC or 24VAC.
Both power options are acceptable and will be required for some CCTV installations.
Central power supply is available in 4, 8, 16 and more channels.
The traditional video cable is RG59 coaxial cable.
Siam dual cables are commonly used to provide RG59u coaxial cables and a pair of 18-gauge wires for camera power requirements.
Dual cables allow single cables for video and power to run to each camera. Cat-5 OptionsUTP (twisted pair)
Wiring is becoming more and more popular with cats5e/Cat-
Cabling used in the network.
The CAT cable is lighter and cheaper than the coaxial cable, and the Barron connector is required to match the impedance of the video signal.
Coaxial cable and UTP connections up to 1000 are acceptable.
Balun is used to match the impedance on Cat-
