' system led to the apprehension of nearly 30,000 suspects

Cameras placed along Texas' 1,200-mile border with Mexico have captured the stream of illegal immigrants sneaking into the country on a daily basis.

The network of more than 1,000 motion detectors, similar to those used to film wildlife, have been placed strategically in areas that have not been secured - where Mexican citizens can cross and evade capture with ease.

They helped border guards apprehend nearly 30,000 suspects and led to 88,400 pounds of drugs being seized in 2014 as part of Operation Drawbridge.

The system has also had a significant impact on Mexican cartels and their ability to smuggle narcotics, people and stolen vehicles between the two countries.

The startling images have been revealed as President Obama continues to fight to push through an executive order to shield illegal immigrants from deportation.

Earlier this month a federal judge in Texas refused to lift a temporary block on a White House immigration plan.

According to the Texas Department of Public Safety, the 'sophisticated' cameras are stationed on ranches and farms on the border.

The turn on when movement is detected and are monitored in real-time, around-the-clock by a number of agencies.

If they think suspicious activity is taking place, they alert law enforcement in a bid to get them to cut them off.

Steven McCraw, the director of the agency, said: 'Every day, sheriff's deputies, police officers, Border Patrol agents and state law enforcement officers in the Texas border region risk their lives to protect Texas and the entire nation from Mexican cartels and transnational crime.

'This innovative use of technology has proven to be a force multiplier in detecting the smuggling attempts along the border, which is critical to interdicting criminal activity occurring between the ports of entry.

'Any time law enforcement interdicts a smuggling attempt, we consider it a significant gain in the fight against the cartels and their operatives.

'The collaborative law enforcement efforts of Operation Drawbridge have bolstered our ability to combat the exploitation of our border by these ruthless criminals.'

In March it was revealed more immigrants are choosing more remote and dangerous crossing points to make it to the United States.

The Border Patrol has responded by expanding its search-and-rescue teams to monitor the area, as a growing number of bodies of suspected illegal immigrants are being found.

Many of the bodies are being discovered just southwest of Mission, Texas, where the fire department's dive-and-rescue team has had a busy winter. In January and February alone, it recovered at least six bodies in the murky canals.

In February, governor Greg Abbot claimed that had 20,000 illegal immigrants had already entered the country since the start of the year.

Some carry guns as they try to cross the border, but agencies have been able to seize larger numbers of the weapons following the installation of the cameras
