Ten Reasons to Buy a Network Camera or what your analog camera vendor wont 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 >Benefits –Superior image quality –Full image details –Precise, accurate information Crystal clear images even with a high degree of motion in the scene Entire image captured at one time Progressive scan

1 – End to interlace problems En komplett bildruta med progressiv scan One complete frame using progressive scan

1 – End to interlace problems Interlaced scan Progressive scan

2 – Power over Ethernet increases savings and reliability

2 – Power over Ethernet > Benefits –Cost savings –Reliability with centralized power backup –Simple installation >Not available No need for power outlet at camera location Industry standard IEEE802.3af

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

3 – Megapixel resolution >Stuck with NTSC/PAL resolution >0.4 Megapixel at 4CIF and 0.1 at CIF >Limited image details Many resolutions Different aspect ratios 1 megapixel is 10x the resolution of CIF, 2 megapixel is 20x! Digital PTZ > Benefits –More details, easy identification –Digital PTZ, higher reliability and simultaneous pan/tilt

4 – Intelligence at the camera level

4 – Intelligence at the camera level >Not available Intelligent video Purpose-built, highly integrated hardware Intelligent features: Built-in VMD, Alarm management, Image enhancement Intelligent algorithms: Number plate recognition, People counting > Benefits –More details, easy identification –More productive and effective means of surveillance –Event-driven –Scalable systems

4 – Intelligence at the camera level Hallway Door Excluded Included

5 – Integrated PTZ input/output control

5 – Integrated PTZ input/output control >Cabling separate from the video signal >Costly and cumbersome > Benefits –Less cabling, cost savings, increased functionality and integration potential 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

5 – Integrated PTZ input/output control Example: Typical I/O use – integration with alarm

6 – Integrated audio

6 – Integrated audio 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, cost savings >Only possible with separate audio lines to the DVR

6 – Integrated audio >Entrance control –Remote dialog and gate/door control >Listen in on remote sounds –Audio surveillance >Provide audio feedback to surveillance scenes 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 Video encryption Authentication using encrypted certificates Authorization: to verify and approve the identity of the device Privacy > Benefits –Secure image capture –Secure transmission –Evidence trail secured

7 – Secure communication >Examples of achieving privacy –VPN –SSL/TLS (HTTPS)

8 – Flexible, cost-effective infrastructure choices

> Benefits –Image quality, flexibility, scalability, future-proof –Resulting costs comparatively low >Expensive coax, proprietary fiber, wireless >Distance affects image quality >Adding power, I/O and audio further complicates this situation 8 – Flexible, cost-effective infrastructure choices IP = established, standardized, interoperable Digital images = no quality reduction Many streams transmitted over the same line A single network wire = hundreds of simultaneous full frame rate video streams

8 – Flexible, cost-effective infrastructure choices IT – Security convergence IP in Industrial Solutions IP in security IP in Voice Over IP IP in Building Management Systems The IP way

9 – True digital solution

9 – True digital solution >With every conversion image quality is lost: –Analog signal digitized in cameras DSP –Digital signal converted back to analog for transport over coax –Signal once again digitized at the DVR for recording > Benefits –Superior image quality Images digitalized once Stay digital No unnecessary conversions No image degradation

9 – True digital solution

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?
