Ten Reasons to Buyy a Network Camera OR WHAT YOUR ANALOG CAMERA VENDOR WON’T TELL YOU AND THE EXPERTS AT TRIAD SECURITY SYSTEMS WILL!
Triad Tidbit Focus This presentation will reveal 10 of the most important functional differences between analog and network/digital cameras
10 – End to interlace problems • Interlaced scan • Each image formed from two interlace fields • Blurriness from capturing moving objects, even when connected to a DVR
Progressive scan
Entire image captured at one time
Crystal clear images even with a high degree of motion in the scene
• Benefits • Superior image quality • Full image details • Precise, accurate information
10 – End to interlace problems
One complete O o p frame using progressive scan
10 – End to interlace problems Interlaced scan
Progressive scan
9 – Power over Ethernet • Not available
IEEE802 3af IEEE802.3af IEEE802.3at (Hi PoE) Industry standards
ONE cable for video data & power
Enables heating and cooling
No need for power outlet at camera location
• Benefits • Cost savings • Reliability with centralized power backup • Simple & cost cost-efficient efficient installation
9 – Power over Ethernet
Both network cameras with and without built-in support for PoE can take advantage of a UPS device
8 – Megapixel resolution & HDTV capabilities • Stuck with NTSC/PAL resolution • 0.4 Megapixel at 4CIF and 0.1 at CIF • Limited image details Many resolutions resolutions, higher resolutions
Different aspect ratios
1 megapixel megapi el is 10x 10 the resolution of CIF, 2 megapixel is 20x!
Exceptional image quality • Benefits • More details, easier identification • Digital PTZ, higher reliability and simultaneous pan/tilt

• Full frame rate 25/30 and/or 50/60 fps • Wider color spectrum than standard TV Better color representation t ti
Guaranteed resolution
Full frame rate
Wide screen format
7 – Intelligence at the camera level • Not available
Intelligent Video
Purpose built highly Purpose-built, integrated hardware
Automatic analysis, detection & alerts
Initiates recording, alarms or other action
• Benefits • • • •
More productive and effective means of surveillance Event-driven – relieves burden from operators Scalable systems – efficient monitoring of large systems Lower costs – network stoarage & staff

7 – Intelligence at the camera level – examples
Active Tampering Alarm Detects re-direction Detects blocking Detects covering and spray-painting Accidental or intentional disruption
Automatically alerts the operator when normal camera operation is disrupted
IP Network Camera
7 – Intelligence at the camera level – examples Auto-tracking, enables a camera
to automatically follow moving object People counting, object counting License plate recognition Virtuall ffence, lline-crossing Audio detection Face recognition, recognition gender recognition and much more to come
6 – Integrated PTZ input/output control • Cabling g separate p from the video signal g • Costly and cumbersome
PTZ control over the same network th t transports that t t the video
PTZ commands sent over the IP network
Integrated I/O can trigger anything and be triggered by anything
• Benefits • Less cabling, cost savings, increased functionality and integration potential
6 – Integrated PTZ input/output control
Example: Typical I/O use – integration with alarm
5 – Integrated audio • Only possible with separate audio lines to the DVR
Audio captured at the camera
Synchronized with the video
Can be integrated into the same video stream
Two-way audio (duplex, half duplex, simplex)
• Benefits • Many possibilities: simplex, half duplex, full duplex • Synchronized audio and video • Easy to install install, cost savings
5 – Integrated audio • Entrance control • Remote dialog and gate/door control • Listen in on remote
sounds •
Audio surveillance
• Provide P id audio di ffeedback db k
to surveillance scenes • Audio can also be used to trigger recordings, alarms, etc.
Example: Communicate and open a door remotely
4 – Secure communication • No encryption • No authentication • Anyone can tap into the video or replace the signal from a camera with another video signal Video encryption
Authentication using encrypted certificates
Authorization: to verify and approve the identity of tthee dev o device ce
Privacy
• Benefits • Secure image capture & transmission • Standardized authentication authentication, IEEE802 IEEE802.1X 1X • Evidence trail secured
4 – Secure communication • Examples p of achieving gp privacyy • VPN • SSL/TLS (HTTPS)
3 – Flexible, cost-effective infrastructure choices
• Expensive coax, proprietary fiber, wireless • Distance affects image quality • Adding power, I/O and audio further complicates this situation IP = established, standardized, interoperable. Fixed and wireless.
Digital images = no quality reduction
ONE cable for video data, audio, PTZ control and power power.
A single network wire = hundreds of simultaneous full frame rate video streams
• Benefits • Image quality, flexibility, scalability, future-proof • Resulting R lti costs t comparatively ti l llow • Standardized fixed and wireless infrastructure
3 – Flexible, cost-effective infrastructure choices • Based on open IP standards • Easy E integration i t ti with ith available il bl IP systems t • Utilization of standard IP components • Fixed or wireless networks
The IP way
2 – True digital solution • With every conversion image quality is lost: • Analog signal digitized in camera’s DSP • Digital signal converted back to analog for transport over coax • Signal once again digitized at the DVR for recording
Images digitalized once
Stay digital
No unnecessary conversions
No image degradation • Benefits e e ts • Superior image quality
2 – True digital solution
1 – Lower total cost of ownership Independent study in 2008, based on real RFPs shows that: The total cost to acquire, install, and maintain a 40 camera system is 3.4% lower than an analog solution 32 cameras is the h b break-even, k iff no infrastructure f is previously installed
From 16-32 cameras, the costs are similar
Always lower total cost for an IP-based system if the
infrastructure already exists Many y non-quantifiable q advantages g for network video
Flexibility, scalability, image quality, future-proof, etc.
1 – Lower total cost of ownership COMPARE The cost per channel Flexibility and performance CONSIDER Back end applications and storage Industry standard, open-system based servers vs. proprietary hardware like a DVR Infrastructure used
Can it be leveraged for other applications?
Possibilities to integrate with other systems/applications
