DTC Video Receivers

DTC designs and manufactures a wide range of video receivers, from an open frame “brick receiver” designed for our OEM market, to a five receiver, briefcase diversity system with recorder and monitor. Currently we offer standard products in L and S band, with C band products being developed. Most of the products described below are available “off the shelf” in low volumes.

The Vortex™ Series of receivers are ideal for low cost, point-to-point links. The open frame version is a light weight board level assembly, with no external packaging. A rugged, fully enclosed version is available as well. Both feature ten user programmable video channels, each with two user programmable audio sub-carriers. Received Signal Strength Indication is available either as an analog voltage level, or may be interrogated via a serial port. Encryption using Ovation Micro-ViewLock II™ is available as an option, and mounts internal to the unit.

The Vortex™ Diversity Series receivers are ideal for mobile applications, or where there is significant movement of objects in the environment, such as vehicles. All DTC diversity receivers use true diversity, meaning multiple antenna/receiver pairs are used to evaluate one transmitted signal arriving via different RF paths. The best signal is selected and switched to during the horizontal retrace, or over 15,000 times per second. The Vortex™ Diversity Series uses two receivers and two antennas, which may be located remotely from the receivers. They are available as open frame or packaged units.

The MiniPIX™ Series of briefcase receiver/recorders provides an ideal receive platform in law enforcement and military applications. Two receivers are mounted in a briefcase, with two antennas mounted in the lid. DTC’s proprietary VideoVoter™ diversity logic board is used to select the best received signal. The unit operates off AC, DC or internal, rechargeable batteries.

Three recorder/monitor options:

• The MiniPIX™ MPX-800 uses a Sony GVD-800 with Super8 recording format and a 4” color monitor
• The MiniPIX™ MPX-1000 uses a Sony GVD-1000 with MiniDV recording format and a 4” color monitor
• The MiniPIX™ MPX-123 uses a 10” monitor in the lid, and offers an optional Sony GVD-200 recorder using the Super8 recording format

Note: Briefcase receivers are not shown for security purposes.

Choose the solution that best fits your need.

The SplitPIX briefcase and rack mount units feature cross band diversity operation. You have your choice of operation using two receivers in a “high” band, or two receivers in a “low” band. The active band is selected by a switch on the panel. In effect, you get the performance of two complete MiniPIX™ systems in one unit. This flexibility is ideal when you have transmitters operating in multiple bands.

The SuperTRIAD and VR-450 provide additional performance capability by offering up to five receiver/antenna pairs. Antennas may be located up to 100’ from the receivers. The rack mount SuperTRIAD is ideal for surveillance and command vehicle operation. The VR-450 briefcase version is perfect for portable operation where you have time to set up antennas, which are connected via the exterior of the case. Having more antennas allows you to place antennas over or around obstacles, generally improving your video quality.
