Ten Reasons to Buy a Network Camera or what your analog camera vendor won’t tell you
Focus 10 of the most important functional differences between analog and network cameras
1 – End to interlace problems
1 – End to interlace problems Interlaced scan Each image formed from two interlace fields Blurriness from capturing moving objects, even when connected to a DVR Crystal clear images even with a high degree of motion in the scene Entire image captured at one time Progressive scan Benefits Superior image quality Full image details Precise, accurate information
1 – End to interlace problems One complete frame using progressive scan En komplett bildruta med progressiv scan
1 – End to interlace problems Interlaced scan Progressive scan
2 – Power over Ethernet increases savings and reliability
2 – Power over Ethernet Not available Benefits IEEE802.3af No need for power outlet at camera location ONE cable for video data & power IEEE802.3af IEEE802.3at (Hi PoE) Industry standards Enables heating and cooling Benefits Cost savings Reliability with centralized power backup Simple & cost-efficient installation
2 – Power over Ethernet Both network cameras with and without built-in support for PoE can take advantage of a UPS device
3 – Megapixel resolution & HDTV capabilities
3 – Megapixel resolution & HDTV capabilities Stuck with NTSC/PAL resolution 0.4 Megapixel at 4CIF and 0.1 at CIF Limited image details Many resolutions, higher resolutions Different aspect ratios 1 megapixel is 10x the resolution of CIF, 2 megapixel is 20x! Exceptional image quality Benefits More details, easier identification Digital PTZ, higher reliability and simultaneous pan/tilt
3 – Megapixel resolution & HDTV capabilities CIF Megapixel
3 – Megapixel resolution & HDTV capabilities Resolution comparisons Aspect ratios HDTV 1280 x 720 HDTV 1920 x 1080
3 – HDTV image quality & HDTV capabilities SMPTE HDTV standard guarantees: Resolution 1280x720 in 16:9 format, SMPTE 296M (720p) 1920x1080 in 16:9 format, SMPTE 274M (1080p/i) Full frame rate 25/30 and/or 50/60 fps Wider color spectrum than standard TV Better color representation Guaranteed resolution Enables heating and cooling Wide screen format
4 – Intelligence at the camera level
4 – Intelligence at the camera level Not available Initiates recording, alarms or other action Purpose-built, highly integrated hardware Intelligent Video Automatic analysis, detection & alerts Benefits More productive and effective means of surveillance Event-driven – relieves burden from operators Scalable systems – efficient monitoring of large systems Lower costs – network, storage and staff
4 – Intelligence at the camera level Included Excluded Included Excluded Hallway Door
4 – Intelligence at the camera level – examples Active Tampering Alarm Detects re-direction Detects blocking Detects covering and spray-painting Accidental or intentional disruption IP Network Camera Active Tampering Alarm! Automatically alerts the operator when normal camera operation is disrupted
4 – Intelligence at the camera level – examples Auto-tracking, enables a camera to automatically follow moving object People counting, object counting License plate recognition Virtual fence, line-crossing Audio detection Face recognition, gender recognition and much more to come
5 – Integrated PTZ input/output control
5 – Integrated PTZ input/output control Cabling separate from the video signal Costly and cumbersome Integrated I/O can trigger anything and be triggered by anything PTZ commands sent over the IP network PTZ control over the same network that transports the video Benefits Less cabling, cost savings, increased functionality and integration potential
5 – Integrated PTZ input/output control Example: Typical I/O use – integration with alarm
6 – Integrated audio
6 – Integrated audio Only possible with separate audio lines to the DVR Two-way audio (duplex, half duplex, simplex) Synchronized with the video Audio captured at the camera Can be integrated into the same video stream Benefits Many possibilities: simplex, half duplex, full duplex Synchronized audio and video Easy to install, cost savings
6 – Integrated audio Entrance control Listen in on remote sounds Remote dialog and gate/door control Listen in on remote sounds Audio surveillance Provide audio feedback to surveillance scenes Audio can also be used to trigger recordings, alarms, etc. Example: Communicate and open a door remotely
7 – Secure communication
7 – Secure communication No encryption No authentication Anyone can tap into the video or replace the signal from a camera with another video signal Privacy Authentication using encrypted certificates Video encryption Authorization: to verify and approve the identity of the device Benefits Secure image capture & transmission Standardized authentication, IEEE802.1X Evidence trail secured
7 – Secure communication Examples of achieving privacy VPN SSL/TLS (HTTPS)
8 – Flexible, cost-effective infrastructure choices
8 – Flexible, cost-effective infrastructure choices Expensive coax, proprietary fiber, wireless Distance affects image quality Adding power, I/O and audio further complicates this situation A single network wire = hundreds of simultaneous full frame rate video streams Digital images = no quality reduction IP = established, standardized, interoperable. Fixed and wireless. ONE cable for video data, audio, PTZ control and power. Benefits Image quality, flexibility, scalability, future-proof Resulting costs comparatively low Standardized fixed and wireless infrastructure
8 – Flexible, cost-effective infrastructure choices Based on open IP standards Easy integration with available IP systems Utilization of standard IP components Fixed or wireless networks IP in security IT – Security convergence IP in Building Management Systems The IP way IP in Industrial Solutions IP in Voice Over IP
9 – True digital solution
9 – 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 No image degradation Stay digital Images digitalized once No unnecessary conversions Benefits Superior image quality
9 – True digital solution
10 – Lower total cost of ownership
10 – 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 break-even, if no infrastructure 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 non-quantifiable advantages for network video Flexibility, scalability, image quality, future-proof, etc.
10 – 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
