Page 8: Getting Started And Basic Operation
Getting Started and Basic Operation 1.1 Which Model do I have? The DropCam is marked with a product code panel as shown below, the panel gives the product code, serial number and bar code. domo SOL4DCAM-P-200250 SN 123456 Made in the UK The domo product code can be referenced in the table below.
Page 9: Controls
Controls The DropCam has dual button control panel, a seven segment display indicator and LEDs. Button 1 is the Control Button and is coloured green. The control button is used to enable the DropCam and allows users to cycle between 8 internally stored configurations.

Page 11 from 1 to 8 and then back to 1, release the button when you have reached the desired configuration. After approximately 10 seconds the display will shut off, the LED will continue to flash once per second to show charging status. To turn off the unit, press and hold the button, the display will show the configuration number and then turn off, as will the LED.
Page 12 Connecting the Antennas The DropCam is supplied with flexible omni directional antennas with a nominal gain of 2dBi. The antenna should be connected to the SMA female connector on the rear of the unit, care should be taken to not over tighten the SMA. The supplied antennas are suitable for all general purpose transmissions, however for longer range transmissions customers may choose to connect higher gain antennas, and domo has a range of...
Page 13 The Camera The DropCam is equipped with a camera module, the module can be connected directly to the DropCam body, or remotely using a cable. DropCam with camera connected directly. DropCam with remote camera The camera head can be removed from the body, by gripping the camera head and pulling firmly away from the body.
Page 14 Sensitivity: 0.05Lux Signal to noise: >46dB The 3.4mm Lens fitted as standard offers a wide field of view, suitable for surveying a room. However the standard camera accepts M12 lenses and is supplied with additional lenses for longer range surveillance. Changing the Lens Interchanging lenses is a user operation, and there is no need to return the equipment to domo to do this.
Page 15 Sensitivity: 60dB +/-3dB Mounting the DropCam The DropCam is a rugged device designed for out door deployment in adverse conditions. The DropCam unit is supplied with a range of mounting options to facilitate easy deployment. 1) ¼ ‘’ threaded tripod mount in the base of the DropCam facilitates the connection to general purpose tripods and camera mounts.
Page 16: Advanced Operation
Advanced Operation 1.1 SOLO System PC Controller Application Software Advanced control of the SOLO4 DropCam system is available by using PC control applications. Typically users may want to customize the default configurations to control settings such as frequency, scrambling keys, modulation parameters, and video resolution.
Page 17 For both controllers, changes can be made to the unit configuration using the drop down and data entry fields. Changes are only applied to the unit when the “Apply” button is clicked. Current values, as running in the unit, can be read using the “Refresh” button.

Page 20 Advanced TX Controller Window Output Frequency (MHz) The transmit frequency can be changed by entering the new desired frequency in this field. Values outside the range supported by a particular transmitter type will be rounded to the highest of lowest supported frequency as appropriate.
Page 21 Link Bitrate Sensitivity 2.4Mb/s -99dBm 1.2Mb/s -102dBm Narrow Band Guard Interval This option applies to SOLO4 transmitters only. The Guard Interval defaults to 1/16. Interval 1/8 is also available for very long range (aircraft downlinks) applications. Narrow Band Modulation This option applies to SOLO4 transmitters only. The COFDM mode can be changed between QPSK and 16QAM.
Page 22 Output Attenuation This control can be used to make minor adjustments to the output power level, but in normal operation should be disregarded. Video Input This control is used to select the composite video input standard. Options are PAL, and NTSC both with and without 7.5 IRE pedestal. The licensed SDI digital video input can also be selected.
Page 23 Horizontal resolution The video coding resolution can be selected from 704, 528, 480 and 352 pixels. Changing the horizontal resolution to lower values will make the coded picture softer. Care should be taken to match the horizontal resolution to the resolution of the camera connected to the transmitter;...
Page 24 Data With this ON / OFF control the user can select whether the transmitter passes serial RS232 data across the RF link to the receiver. Data Baud Rate This field is used to select the baud rate of any RS232 serial data component to be passed from the transmitter to the receiver across the RF link.
Page 25 Serial Number (Status Only) This status information is the electronic serial number of the transmitter PCB. This number can be exchanged with domo to purchase extra licensable features, such as upgrades to support AES encryption. Chaining (Status Only) This field reports the status of the chaining input to the SOLO transmitter, and is not active in current units.
Page 26: Fault Finding
Fault Finding Symptom Suggested Action No RF Link Check a suitable transmitter RF source is active, on correct frequency. Ensure Downconverters are connected. Ensure antennas are connected to downconverters. Ensure there is no interfering signal. Poor link Poor performance of the link can occur for the following reasons. performance Interference.
