AE Specification SDN-520

1.0 Description.

The Day / Night video camera shall be a Samsung Model number SDN-520P or equivalent. The sensor technology shall be 1/3” EX-VIEW HAD IT. The camera shall incorporate Infrared Cut -Filter Removable (ICR) technology, to facilitate automatic switching between colour / monochrome operation. The camera described shall be engineered to industrial grade and provide high sensitivity, high-resolution, and full functionality. The camera will be a true Day / Night camera with Digital Signal Processing (DSP).

2.0Tender Specification.

2.1.0 Sensitivity, Resolution and Signal to Noise Ratio (SNR)

The camera shall have a minimum sensitivity of 0.5lux at F1.2 (colour) and 0.01 lux at F1.2 (monochrome).

The camera shall incorporate a 1/3” interline transfer charge coupled device (CCD) with approx. 470,000 picture elements (795H x 596V), the minimum active picture elements being 752H x 582V. The camera shall produce a picture with more than 480TV lines horizontal resolution in colour and 520TV lines horizontal resolution in monochrome mode. The camera shall have a signal to noise ratio (SNR) greater than 48db. The video output level shall be 1.0 Vp-p (75 ohms PAL composite) with a BNC type connection.

2.2.0ICR Switching, Spectral Response and Lens Connections

The mechanical ICR will have a MTBF rate of 7000 operations (minimum). The camera shall have ICR colour / monochrome adjustable level switching control. The camera shall incorporate electronic filter technology allowing for light sources above 800nm.

The spectral response of the camera will ensue that a picture is produced where no “visible” light is available (greater than 930nm).

The camera shall be CS-mount as default and C-mount selectable with the aid of C-mount adapter (supplied as standard). The camera shall have auto iris facility allowing connection of Direct Drive DC iris control (galvanometric without amplifier) lenses, and Video Auto iris control (lenses with inbuilt amplifier) lenses.

The camera shall include 1 x ¼” – 20UNC mounting plate which can be attached to either the top or bottom of the camera.

2.3.0Motion Detection, White Balance, RS232, OSD

The camera shall offer a user definable motion detection zone, with an alarm output and on-screen (text) annunciation on breach of alarm.

The camera shall have multiple white balance settings (ATW,AWC, and Manual) to allow for white balance correction under a varied range of ambient light sources, with differing colour temperatures.

The camera shall be capable of RS232 control, allowing all menu options (functions) to be accessible and programmed remotely.

The camera shall have an On Screen Display (OSD) screen set-up menu.

2.4.0Mechanical, Electrical and Conformance

The camera dimensions shall not exceed 55(W) x 57(H) x 135(L) mm and weigh approximately 400g(without lens and camera mounting plate). The camera casing will be constructed of a durable metal cabinet and shall be magnetically and electro statically shielded. The camera will feature solid-state components to resist shock and vibration. Low voltage dual supply (12vdc and 24vac) and mains voltage (230VAC) models being available. Power requirements for the cameras shall be 12VDC (3.5W) / 24VAC (3.8W) and 230VAC 50Hz (4.0w).(without lens connected)

The camera shall be ISO9001 certified and CE listed.
