Ten Reasons to Buy a Network Camera
Focus
10 of the most importantfunctional differences
between analogand network cameras
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 clearimages evenwith a high
degree of motionin the scene

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
Example: Typical I/O use –integration with alarm

Two-way audio (duplex,half duplex, simplex)
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

PrivacyPrivacy
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

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

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
