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
