What is CCTV?
CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.

How does CCTV work?
CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private Coaxial or Cat 5 cable runs, Wireless or Internet communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.

CCTV Technology:
Older CCTV systems used small, low-resolution black and white monitors with no interactive capabilities. Modern CCTV displays can be colour, high-resolution displays and can include the ability to zoom in on an image or track something (or someone) among their features. Talk CCTV allows an overseer to speak to people within range of the camera's associated speakers.

CCTV is used for a variety of purposes, including:

Maintaining perimeter security in medium- to high-secure areas and installations.

Helping with home care for the elderly.

Observing behavior of incarcerated inmates and potentially dangerous patients in medical facilities.

Traffic monitoring.

Overseeing locations that would be hazardous to a human, for example, highly radioactive or toxic industrial environments.

Building and grounds security.

Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls (for example, in a diamond cutting or sorting operation; in banks, casinos, or airports).

CCTV is finding increasing use in law-enforcement, for everything from traffic observation (and automated ticketing) to observation of high-crime areas or neighborhoods.

CCTV Applications:



Private Places:

• Less use of white light means less light pollution.
• Active Deterrence: Warn off intruders during the intrusion.
• App Alert: Notification if movement detected.
• Colour Monitoring: Presents colour alarm videos.
• Scenarios: Homes, Shops, Factories, Warehouses, etc.



Public Areas:

• Active Deterrence: Customized sounds and light alarm to warn the target in the area.
• Accurate Detection: Focuses on human and vehicle targets to accurately identify real targets.
• Ecosystem: One-tap disarming with alarm-in port or DMSS.
• Scenarios: Fire exits, emergency exits, etc.

We at Grange can provide the solution for your problem with simple systems for your home or more sophisicated requirements in the workplace and public areas:

We can offer Dahua's TIOC (Three in One Camera) Solution.



Smart Dual Light:

• IR Mode (Optional): Only the IR illuminator is ON. It is suitable for scenes where supplementary warm light is not required, significantly reducing light pollution.

• Warm Light Mode (Optional): Only the warm light is ON. It is suitable for scenes that require color video footages.

Voice Catcher Technology:

• Newly-designed Dual Mic Array intercepts external circuit interference.

• Audio pick-up distance is increased by 7 meters compared with the previous version of TiOC in a lab environment.

• The Dahua VoiceCatcher reduces noise and extracts audible audio signals.

Better Image:

• First Dahua camera powered by OPC (Optical Path Technology). It corrects the refraction angle of different light path. With F1.0 large aperture lens, it outputs brighter and clearer black & white images.

• 4K Real-time: Smooth 4K real-time images at 30 fps even when AI is enabled, with high brightness using F1.0 large aperture.



AI Features:

• With upgraded AI capabilities, the SMD function filters out irrelevant objects in the scene. Equipped with new deep learning algorithm, SMD 4.0 is optimized to filter out small and large animals in the scene to avoid triggering false alarms.

• The perimeter protection function based on tripwire and area intrusion sends an alarm only when unwanted movements triggered by human or vehicle targets occur, saving users from unnecessary actions caused by false alarms.

• The Dahua AI SSA (Scene Self-adaption) technology is based on deep learning algorithm that can intelligently identify multiple scenes and adjust to their optimal images.

Auto Tracking:

• Smooth Tracking Process - Combined with PFA 3.0 algorithm (a deep fusion of intelligent algorithms and focusing algorithms), it realizes touchless focusing during the tracking and capturing process.

• Long Tracking Distance - With the Automatic Tracking 2.0 algorithm as its foundation, the requirements on the tracking size of the target are further reduced, making the target size smaller and the tracking distance longer. The tracking distance of Automatic Tracking 3.0 can reach up to 870 meters.

To deter burglars who dont want to be seen Security Lighting is installed, but when installed they are also an aid to visitors approaching your property in the hours of darkness.
