What is network video surveillance

MegaPixel IP SurveillanceVideo Explained

by Exacq-VideoSurveillance.com

Resolution

• MegaPixel Technology allows for detail that was once un-imaginable

VGA Analog vs MegaPixel

• A (1) one Megapixel Surveillance Camera has the resolution of 4 VGA quality Cameras and up to 8 CIF Analog Cameras

Camera Inputs and Outputs• Focus and Focal length adjustments are the key to

clear video• Built in microphones, 2 way audio and I/O ports

are additional benefits

Pixels Per Foot Calculations• Axis Camera Configuration tools provide accurate px/ft

calculations• 160 px/ft is a European Standard admissible in court for

identifying a face.

Edge Storage

• Edge Storage enabled security cameras allow memory cards to store recorded video.

• ExacqVision offers management solutions to optimize recorded video with minimal storage

• Some video recording tools include: recording on motion, triggers, video masks, scheduling, frames per second, resolution, multi-streaming and virtual cameras.

Security Gate Example for Edge Storage

• Security Gates do not normally have internet access and Edge storage provides a way to record the video on a SD Card

• The 32GB SD card will write over itself within a set number of days.

• Below are 2 scenarios, one camera is set to record for 14 days on 32GB Memory Card. The second camera will write over itself every 7 Days. The difference is the Frames Per Second, % of motion and the resolution.

Popular MegaPixel Cameras

• Axis M-1054 & Axis P-1344

20 MegaPixel 180 Degree Camera

• Potentially replaces 5-10 analog cameras

Video Encoders

• Take advantage of analog infrastructure already installed and covert them to IP with a video encoder

Management Software

Fixed Dome & PTZ Surveillance Cameras

• Axis Communications Product line has a camera for every situation

PTZ

Wireless

• Wireless IP Cameras are just beginning to come in 1 MegaPixel and above resolution

• H.264 video compression allows for high definition video to be streamed a wireless router

Network Video Recorder• A NVR is a IP Camera storage device with a set amount of Hard

Drive Space• Depending on the amount of cameras being recorded, Frame Rates,

amount of motion, and resolution a NVR is built to accommodate any number of Days of recorded video.

Depth of Field• Understanding your target depth of field should help you choose the correct IP

Camera• Use Axis Configuration Calculator for each camera to help

Event Triggers• Event triggers are either notifications or actual actions

the video management system can command
