INDUSTRIAL/COMMERCIAL CCTV-CAMERA & DIGITAL VIDEO RECORDING SYSTEM |
|
General surveillance/security CCTV covers a
broad range of commercial, industrial, and governmental applications.
Systems can range from a single fixed camera and monitor system to several
hundred cameras controlled by a computer-based automated control system with
a matrix video switcher, a series of joystick controllers, a range of
monitors, and possibly several control stations. Systems are normally used
to monitor parking lots, work areas, employee entrance areas, high security
areas, building perimeters for governmental complexes, campuses, airports,
correctional facilities, and the like. Volume production, major advances in technology and growing demand for ever more sophisticated applications have led to some exciting developments in CCTV systems - along with lower prices! |

What are the advantages? |
There is no doubt that a quality CCTV system, when properly installed for an appropriate application, can be an invaluable aid to any organization, and Insights' carefully selected products offer excellent value for money and hassle free performance. . . |
Burglar Alarms |

| There are a number of advantages to remote monitoring. First of all is the cost of security and it solves problems of protection. | Remote CCTV monitoring adds visual verification to alarm calls helping reduce every Police Officers nightmare false alarms. | ||

Conventional CCTV is great until something happens, its then you find yourself looking through hours of video tape only to find a masked intruder happily waving at your camera as he vandalizes your premises. Remote Monitoring adds teeth to CCTV it lets us react immediately stopping damage before it happens. |
Can only be in one place at a time, they need breaks and they can be threatened or bribed and suffer from all the normal human failings | ||

What is Remote CCTV Monitoring? |
What do you do if someone is seen? |
||
|
A very simplified explanation would be, it is CCTV Cameras combined with alarm sensors which are used to protect property When a sensor is activated the system using telephone lines brings up live pictures in our Control Room of events as the unfold. Our Controllers can then take full control of the cameras zooming in on suspects and following them. The Control Room can also dial in to the system to carry out patrols, escort late working staff to their cars or over see deliveries, etc. |
If an intruder is seen we will immediately contact the Police giving them a running commentary, intruder do not know we are watching so the odds of catching them are high, we also record close up images. The Police response to our calls is excellent, we put a bit of excitement back in to their job, by having visual verification of someone on site. 94% of burglar alarm calls they attend are false. False alarms involving employee’s are eliminated by the use of pin numbers and detailed site instructions. |

| Image Compression Algorithm |
-File size increases when input images are transformed into digital
images -Data compression technology used to improve recording speed storage capacity |
|
| DCT (Discrete Cosine Transform) Method |
-CODEC (JPEG, MPEG1, MPEG2, H263, etc.) -Supports a broad range of end users -Flexibility of saved data -Disadvantage - 8X8 Mosaic Block Noise from image restoration -Difficult image restoration when compressed data is damaged |
|
| Fractal (Chaos) Method | -Use special area (high compression rate & low processing speed) | |
|
|
||
| Image storage |
-24 hours operation, 16 cameras produces 15
GB of images |
|
|
|
||
| Motion Detection |
-Software based without external sensors -Recording begins when the camera detects motion |
|
|
|
||
| Overlay | -Video display without external equipment | |
| Scheduled or continuous video recording advantages | -Utilizing high compression techniques | |
| Display | - High resolution display | |
| Back Up System | - Multiple back-up options (CD-ROM, DVD, ZIP Driver, etc.) | |
|
|
||
| Convenient system |
- Handle up to 4 or 16
color cameras in real time - Multiple camera views simultaneously on the screen |
|
| Monitoring |
- Remote surveillance
monitoring and recording |
|
| Motion Detection | - Motion detection capability (High detection/Event recording) | |
| Key Advantages of DVR | -Stability (No bugs, Auto
reconstruction capability, System protection) -High image quality -High recording speed -High speed detection capability.. ex) 30 frame/sec - Convenience |
