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
Interlaced scan Each image formed from two interlace fields Blurriness from capturing moving objects, even when connected to a DVR Progressive scan Entire imagecaptured atone time Crystal clearimages evenwith a highdegree of motionin the scene • BENEFITS • Superior image quality • Full image details • Precise, accurate information 1. End to interlace problems
One complete frame using progressive scan 1. End to interlace problems
Interlaced scan Progressive scan Interlaced scan 1. End to interlace problems
2 Power over Ethernet increases savingsand reliability
Not available IEEE802.3af Industrystandard No need forpower outlet atcameralocation • BENEFITS • Cost savings • Reliability with centralized power backup • Simple installation 2. Power over Ethernet
2. Power over Ethernet Both network cameras with and without built-insupport for PoE can take advantage of a UPS device
3 Megapixel resolution
Different aspect ratios Many resolutions Digital PTZ 1 megapixel is 10x theresolution of CIF,2 megapixel is 20x! • BENEFITS • More details, easy identification • Digital PTZ, higher reliability and simultaneous pan/tilt 3. Megapixel resolution • Stuck with NTSC/PAL resolution • 0.4 Megapixel at 4CIF and 0.1 at CIF • Limited image details
3. Megapixel resolution CIF Megapixel
Resolution comparisons Aspect ratios 3. Megapixel resolution
4 Intelligence at the camera level
Not available Purpose-built, highlyintegrated hardware Intelligent video Intelligent algorithms:Number plate recognition,People counting Intelligent features: Built-inVMD, Alarm management,Image enhancement • BENEFITS • More details, easy identification • More productive and effective means of surveillance • Event-driven • Scalable systems 4. Intelligence at the camera level
4. Intelligence at the camera level Included Excluded Excluded Included Hallway Door
5 Integrated PTZ input/output control
PTZ control overthe same networkthat transportsthe video PTZ commandssent over theIP network Integrated I/O cantrigger anythingand be triggeredby anything • BENEFITS • Less cabling, cost savings, increased functionality and integration potential 5. Integrated PTZ and I/O control • Cabling separate from the video signal • Costly and cumbersome
5. Integrated PTZ and I/O control Example: Typical I/O use –integration with alarm
6 Integrated audio
Synchronized withthe video Audio captured atthe camera Two-way audio (duplex, half duplex, simplex) Can be integrated intothe same video stream • BENEFITS • Many possibilities: simplex, half duplex, full duplex • Synchronized audio and video • Easy to install, cost savings 6. Audio • Only possible with separate audio lines to the DVR
6. Integrated audio • Entrance control • Remote dialogue and gate/door control • Listen in on remote sounds • Audio surveillance • Provide audio feedback to surveillance scenes Example: Communicate andopen a door remotely
7 Securecommunication
Authentication usingencrypted certificates Video encryption Privacy Authorization: to verify andapprove the identity of the device • BENEFITS • Secure image capture • Secure transmission • Evidence trail secured 7. Secure communication • No encryption • No authentication • Anyone can tap into the video or replace the signal from a camera with another video signal
7. Secure communication • Examples of achieving privacy • VPN • SSL/TLS (HTTPS)
8 Flexible, cost-effective infrastructure choices
Digital images =no quality reduction IP = established,standardized, interoperable A single network wire =hundreds of simultaneousfull frame rate video streams Many streams transmittedover the same line • BENEFITS • Image quality, flexibility, scalability, future-proof • Resulting costs comparatively low 8. Flexible, cost-effective infrastructure • Expensive coax, proprietary fiber, wireless • Distance affects image quality • Adding power, I/O and audio further complicates this situation
8. Flexible, cost-effective infrastructure IP in Security IT - Security convergence IP in Building Management Systems TheIP way IP in Industrial Solutions IP in Voice Over IP
9 True digital solution
Stay digital Images digitalized once No image degradation No unnecessaryconversions • BENEFITS • Superior image quality 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
10 Lower total cost of ownership
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?
