PART 2 – PRODUCTS
2.1	GENERAL
A. 	TKH Security Solutions (www.tkhsecurity.com) is the manufacturer of these rack-mount single channel digital video transmitters and receivers with “up-the-coax” control data.
B.	TKH Security Solutions shall produce this product within a quality system in compliance with the ISO-9001.
C.	All equipment and materials used shall be standard components that are regularly manufactured and used in the manufacturer’s system.
D.	All systems and components shall have been thoroughly tested and proven in actual use.
E.	All systems and components shall be provided with comprehensive repair and spare parts replacement. The manufacturer on warranty and non-warranty items shall guarantee the spare parts and the repair.
F.	Use of substitutions shall void the warranty. 
2.2	Product descriptin
A. 	The 9281D series of transmitters/receivers shall digitize and transport one video plus duplex data in “up the coax”-type camera control systems such as the Panasonic Proteus™, Pelco, TOA and other similar systems over one optical fiber. 
B. 	The available Extended Distance transmitter, when used with a standard receiver, shall buffer data and properly inject it onto the video signal in the subsequent frame, and shall overcome the typical 1.5 km distance limitation of standard copper and unbuffered fiber “up the coax.” 
C.	The units shall also provide:
1.	High quality video ≥63 dBw SNR
2.	Uncompressed 9-bit digitizing, oversampling, and digital filtering for very high transmission performance, exceeding the requirements of the EIA RS-250C medium haul specification.
3.	LED indicators to provide an instant overview of the system status.
4.	Compatibility with Network Management System (NMS).
D.	The system shall be highly suited for use in a wide range of operating temperature and in harsh weather conditions, such as in traffic monitoring, incident management, video surveillance in city centers, and airport security.
E.	Models of this system shall be available as either rack-mount or stand-alone units. 
1.	Rack-mount units shall be compatible with a 9002, 9008, or equivalent, power supply cabinet.
2.	Rack-mount units shall be configurable to stand-alone by using a 9003-2 mini-chassis or equivalent.
2.3	Design and performance criteria
A. 	The 9281D transmitters/receivers shall transport one simplex video signal with reverse direction “up-the-coax” control data over one optical fiber.
B.	The transmitters shall have two sections: a video transmitter section and a data receiver section. 

C.	The video transmitter section shall accept one composite video signal in NTSC or PAL format via the BNC video input port. 
1.	This baseband video signal shall be sampled at a 16 Mhz rate by an analog-to-digital converter operating with 9-bits of precision. 
2.	The resulting digital signal shall be serialized and converted to an optical signal for transmission over the fiber. 
D.	The data receiver section’s “up-the-coax” video sync and PTZ control signals shall arrive via an optical receiver transmitted at a second wavelength on the same fiber. 
1.	The received optical signal shall be converted back into a serial bit stream and demultiplexed to recover the signals. 
2.	These sync and control signals shall be then inserted onto the video input BNC. 
E.	The extended distance transmitter shall include a data buffer that shall store the PTZ control data when received and reinsert it onto the proper horizontal retrace line in the next video field, eliminating the link distance limitations due to the “round trip” data delay inherent in non-buffered systems.
F.	The receiver shall convert the optical signal from the transmitter into a serial bit stream and process it with a digital-to-analog converter to recreate the video signal, which shall be output on the BNC connector. 
G.	The receiver shall also detect the video sync and “up-the-coax” control signals and convert them into data signals that are multiplexed and transmitted optically to the transmitter on a different wavelength on the same fiber.
H.	These units shall include a 4-position MODE dipswitch, for additional flexibility and compatibility with many manufacturers’ versions of “up-the-coax” protocols, including Panasonic, Pelco, TOA, and others. 
I.	The transmitters/receiver units shall come as rack-mount, plug-in cards that occupy one card slot in any compatible card chassis (such as a Series 9000). 
1. 	The rack-mount units shall be optically compatible with the standalone models.
2.	The units shall operate on 6VDC from the chassis power supply.
J.	The units shall operate through a wide temperate range (-40° to +74° C / -40° to +165° F).
K.	The units shall meet UL/cUL, CE and FCC part 15 regulatory requirements.
