SMAC-M is a revolutionary video compression technology developed by TeleEye specially for video surveillance and CCTV application.

SMAC-M is the first video coder in the market that uses a multi-stream coding technology to solve the conflicting requirements of simultaneous recording and remote surveillance.

Superior Compression Performance than MPEG-4 Techonology

• For the same HDD, TeleEye RX Series video recording server incorporated with SMAC-M can record 60% more than MPEG-4 and 4 times more than MJPEG or JPEG2000 at the same picture resolution, quality and frame rate.
• For transmission, SMAC-M is about 50% faster than MPEG-4 under ADSL environment.

(1) Recording Comparison :

	Recording Performance
Coder	Resolution: 720 x 576 ; Rate: 25fps	Recording duration for a 200 Gbyte HDD
JPEG	170 GB / day	1.3 days
JPEG 2000	100 GB / day	2 days
M-JPEG	100 GB / day	2 days
MPEG-4	40 GB / day	5 days
SMAC-M	25 GB / day	8 days
SMAC-M: 40% smaller than MPEG-4

(2) Transmission Comparison :

	Transmission on LAN at 100Mbps		Transmission on ADSL at 640kbps
Coder	Resolution: 720 x 576 Rate: 25fps	Resolution: 360 x 288 Rate: 25fps	Resolution: 720 x 576	Resolution: 360 x 288
JPEG	16 Mbps	8 Mbps	1 fps	2 fps
JPEG 2000	10 Mbps	6 Mbps	2 fps	4 fps
M-JPEG	10 Mbps	6 Mbps	2 fps	4 fps
MPEG-4	2 Mbps	1.2 Mbps	8 fps	16 fps
SMAC-M	1.3 Mbps	0.8 Mbps	12 fps	21 fps
SMAC-M shows superior video transmission performance on LAN & ADSL channels
