Physical Security

• The methods for securing access to digital and physical environments continue to evolve.
• Two traditionally distinct areas of physical security which are door access and video surveillance are not immune.
• They’re not only being moved away from strictly on-premises solutions, but are now being integrated to provide a modernized, scalable, and highly secure approach to safeguarding entryways.

What Are the Benefits of an Integrated Access System?

1. Instant Visual Evidence:
   • Immediately see and access footage for events happening at any door, in any location, shortening the time to investigate and resolve security incidents.
   • If available, facial recognition capabilities can help you identify people on camera through the management console.
     
     
2. Always in Sync:
   • When reviewing security footage, precision is non-negotiable.
   • Integrated access systems run events on the same system clock—for both door security and video surveillance ensuring video and access events line up to the millisecond.
     
     
3. Enhanced Visibility:
   • Some integrated systems provide enhanced visibility of door-based activity, so that controllers see who was there, how they accessed the door, including the ability to review footage and dig deeper into user activity.
     
     
4. Proactive Insights:
   • The ability to react to incidents is one thing, but preventing incidents before they happen is essential.
   • Proactive notifications, for example, when occupancy levels reach a certain threshold, suspicious activity occurs, or a person of interest appears allow for immediate action and quick communication with first responders.
     
     
5. Ease of Access:
   • Access control management is about end-user experience, too.
   • Integrated systems make it simple to add or remove users, assign, or deactivate the swipe cards, key cards, or fobs used in conjunction with readers installed at each door.
   • In terms of management, each swipe sends valuable data to the central location to fuel incident response and proactive insights.
     
     

While these benefits of integrated access control certainly impact security management and broader organizational strategies, they help deliver on a fundamental need: safer buildings for employees, occupants, and all visitors.

CCTV

What’s CCTV?

• CCTV means “closed-circuit television” and is commonly known as a video surveillance technology.
• “Closed-circuit” means broadcasts are limited (closed) to a selected group of monitors, unlike “regular” TV, which can be received and viewed by whoever sets up a reception device.
• CCTV networks are commonly employed to detect and deter criminal activities and record traffic infractions, but they also have other uses.

Types of CCTV

1. Dark Fighter Technology Cameras

• These cameras can pick up coloured images in very low-light conditions.
  
• Dark fighter technology can be used in the day and night and offer optimal performance thanks to its wide range of capabilities.
• They are equipped with 1/2" CMOS progressive scan sensors which allows the device to pick up high-quality images and doesn’t require an extra light source – which makes the perfect nighttime security surveillance camera.
• Other benefits of dark fighter technology cameras include:

1. • Smart features: line crossing, audio, and face detection
   • Can be used for a multitude of purposes.
   • High definition

• For example:

• • The new DarkFighterX camera employs 1/1.8” sensors to raise resolution to 4 megapixels.

  • This ‘beyond-HD’ image carries twice the amount of information as 2 MP models.

  • The camera can also deliver full colour images at light levels down to 0.0005 Lux.

  • This also means that, in the future, facial recognition could be possible, even in dim light, thanks to powerful imaging ability and beyond-HD resolution.

The camera has been equipped with an auto wiper to guarantee a better image on rainy days. This function is secured by a rain-detecting sensor on the head of the surface.

Other features include:

• 120 dB WDR, 3D DNR, Chromatic Defog
• Supports H.265+/H.265 video compression
• Rapid focus
• Up to 250m IR distance with Smart IR

3. Internal and External Dome Cameras

• The dome camera is one most commonly used for indoor and outdoor security and surveillance.
• The shape of the camera makes it difficult for onlookers to tell which way the camera is facing, which is a strong piece of design, deterring criminals by creating an air of
  uncertainty.
• Other benefits of internal and external dome cameras include:
  • Ease of installation
  • Vandal-resistant features
  • IR night vision
• For Example:

• • Hikvision DS-2CE55A2P(N)-IRP is a true day/night indoor IR dome camera with 700 TVL horizontal resolution.
