Kamilion's SmartCam project:


Cost per unit Quantity 1: $100.77 + S&H
Most component modules can be obtained at a discount for quantity 3 or quantity 10+.

I estimate a purchase of 12 units would end up to be around $1200 with discounts and adding S&H.


Revised 12/22/14 from China quotes:
$728.77 Quantity 12 quoted from UCtronics for the above equipment
Of this, $107.70 is for connectors suited for other internal projects.
UCTronics Subtotal: $621.07
Subtotal: $515.87 from Newegg (Quantity 12)
$621.07 + $515.87 = $1136.94
$1136.94 + 145.47 = $1282.41
$1282.41 + 199.18 = $1481.59
Cost per unit (Quantity 12): $123.46

$1481.59 + 107.70 = $1589.29

Cost per unit (Quantity 12): $132.44


SmartCam Capabilities:
sealed Waterproof enclosure, 3 sizes available including heater/forced air cooling.
Enclosure unlatches and opens from rear, exposing all components for easy access.
Only a single cat5e cable goes into weatherproof grommet. Wide voltage input allows sharing big remote power supplies.
Can be upgraded to 802.3AF/AT Power over Ethernet for $10 per unit. Upgrade fits inside existing casing.
Can operate internal DC or external AC/DC IR illuminators up to 1,250 Watts for each of 16 channels, expandable to 48 per camera. (not included)

Standard CS-Mount security camera lens. Easily replacable with Fisheye or motorized zoom lens.
Longer lenses require deeper mounting of camera PCB in chassis, possibly moving from 11" to 14" chassis.
Turn camera module upside down inside the casing and the unit is celing mountable.

Omnivision 5647 sensor with infrared cut-out filter removed allowing IR illumination of environment.
1920x1080P @ 30FPS 2.1 megapixel video recording and live streaming to up to 8 simultanious clients.
Sample pictures at http://www.arducam.com/camera-modules/5mp-ov5642/
2592 x 1944 5 megapixel still pictures at 12 FPS. Can be used for autofocus calibration with a suitable lens attached.
High res 2592 x 1944 sample: http://www.arducam.com/wp-content/uploads/2012/11/OV5642_2592x19441.jpg

700Mhz/1Ghz Raspberry Pi application processor with 3D GPU and HDMI & audio output connectors.
100Mbit ethernet to USB2.0 chip included on "$30" Raspberry Pi B/B+ module.
Less expensive "$20" A/A+ module, would support a single 1000Mbit "ASIX-chip" USB3.0 adapter for $13 in volume.

Can drive an external display via HDMI, USB or SPI serial bus.
Linux operating system, choice of 6 off the shelf software stacks or roll-your-own.
8GB local storage capacity allows package manager based installation and innovative adaption to environment.

Local GPU used for motion analysis of video frames, passed on to server for selective compression.
ESCam's "Privacy Mark" feature could easily be implimented with the above features.
Android and iOS direct streaming of individual cameras or live grids of up to 128+ cameras.


Optional future time-wasters:
Installable applications such as 2-way video chat with voice-dial. Scriptable alarms.
Face detection and identification. Employee path tracking and history.
