The LDR (Low Data Rate) transmitter from Cobham Surveillance

is a long-range digital video transmitter with domo

technology at its core. The LDR transmitter sends

informational quality video at reduced frame rates,

compressed to very low data rates (typically 30kb/s),

to an LDR receiver. This high level of compression

and reduced data rate means that the LDR

transmitter can send images over very long

distances. The LDR transmitter occupies at least

50kHz of bandwidth, and can therefore be used

more easily at UHF frequencies. Housed in a

robust, water sealed enclosure and consuming

only 3W, the LDR transmitter is ideal for long-

term outdoor deployments.

Security is ensured with optional AES128/256

bit encryption.

The LDR transmitter is available in a variety

of frequency bands from 300MHz to 1GHz, other

frequencies are available on request.

The LDR transmitter will transmit images in a non-line of sight

environment up to 2km, and line of sight to 20km depending on

mode and frequency - further range can be achieved with the

optional clip-on booster PA.
