Live Video Monitoring Catches: Real Footage of Crimes Stopped
Live video monitoring catches criminals before they finish what they came to do. These aren't staged demos or animated explainers. Every video on this page is real footage from Valley Alarm's ValleyGuard system — captured at real properties across Greater Los Angeles, with real U.S.-based operators intervening in real time.
ValleyGuard combines AI-powered detection with live human operators who see, speak, and act the moment someone crosses your perimeter. When our system flags a threat, an operator verifies it on camera, issues a live voice warning through on-site speakers, and dispatches police with video evidence if needed. That's why remote video monitoring catches what traditional cameras miss — it doesn't just record crime, it stops it.
Below, you'll find our latest verified catches — updated regularly as new incidents are documented.
This is what real-time security intervention looks like.
Every incident below was stopped before theft, damage, or liability.
Live Monitoring Catches Roof Intruder at El Monte Construction Site — October 2025
Saturday afternoon, October 19th. Our operator spotted someone walking across the roof of a nearly finished commercial building in El Monte. Multiple live audio warnings were issued through the ValleyGuard trailer’s speakers. The intruder fled within seconds of the final warning. The property owner was notified by 1:42 PM and LA County Sheriff dispatched by 1:44 PM. No theft, no damage, no loss.
Location: El Monte, CA (San Gabriel Valley)
Fence-Climbers Stopped at East Hollywood Commercial Property — September 2025
Just after midnight on September 15, a man and woman attempted to break into an East Hollywood commercial property. The man crouched down and lifted the chain-link fence for his partner to crawl underneath, then started climbing over himself. ValleyGuard’s AI analytics flagged them the second they touched the fence.
LED deterrent lights snapped on and our operator issued a direct warning — identifying them as intruders in a secure area and informing them police would be dispatched. When the climber kept going, our operator doubled down with a second, more specific warning. Both trespassers turned and left. This wasn’t the first incident at this property either — a previous intrusion had been stopped at the same East Hollywood site just weeks earlier.
Location: East Hollywood, CA
Live Monitoring Catches Intruder at Gardena Storage Facility — September 2025
At 1:46 AM on September 3rd, ValleyGuard's AI detection flagged an individual approaching a box truck at a vacant property in Gardena. Within 38 seconds, a U.S.-based monitoring operator issued a live audio warning through on-site speakers — calling out the intruder's physical description, including their hot pink hair, and warning them they were being recorded.
When the individual remained on-site, the operator escalated to the Los Angeles County Sheriff's Department with video verification and secured a patrol dispatch. The property manager received a voicemail notification before 2:00 AM.
Location: Gardena, CA
Multiple Intruders Attempt to Disable Cameras at North Hollywood Property — August 2025
Less than 24 hours after the August 12 incident at the same North Hollywood vacant building, two guys showed up at 2:39 PM on August 13. This wasn’t random — they came with a plan. ValleyGuard’s pole-mounted surveillance detected both individuals at roughly 110 feet out. Our monitoring team watched them slip through a hole someone had cut in the rod-iron fence and head directly for the camera equipment.
When they started tampering with the cameras, the system detected that the camera views had changed from what it had learned. Our operators issued live warnings before the intruders could finish their sabotage attempt. Both abandoned their plan and fled. No equipment damaged, no theft completed.

Trespasser Stopped at Vacant North Hollywood Property Near Railroad Tracks — August 2025
A vacant building near the railroad tracks in North Hollywood had been dealing with repeated trespassing attempts. At 1:08 AM on August 12, another intruder tested their luck. ValleyGuard’s solar-powered pole-mounted surveillance detected movement the moment someone stepped onto the property and fed live video to our monitoring center — no electrical hookups or internet needed.
Our operator tracked the trespasser across multiple camera angles and delivered a direct voice warning through on-site speakers. The intruder stopped, looked around for the source of the voice, and quickly left. Our team completed a full perimeter sweep to confirm the site was clear. Total intervention time: under three minutes.

Intruder Stopped at Hollywood Development Site at 1:30 AM — July 2025
At 1:30 AM on July 25, a man in a red hoodie hopped a fence onto a vacant Hollywood development property — likely looking for materials to steal or access points to exploit. ValleyGuard’s solar-powered vertical surveillance unit had already detected movement and fed live video to our monitoring center.
Our operator activated deterrent speakers with a description-specific warning: clothing color, pants, and confirmation that police had already been dispatched. The intruder realized he was being watched in real time, knew exactly what he was wearing was being described, and left immediately. No tools stolen, no copper pulled, no project delays the next morning.
Location: Hollywood, CA
Trespasser Caught on Camera at Pomona Renovation Site — July 2025
A Pomona property owner had been dealing with repeated break-ins at a renovation site. We installed a solar-powered mobile security trailer on July 11. Seven days later — just after dark on July 18 — our monitoring team caught someone approaching the site perimeter.
The trailer’s cameras picked up the movement immediately. Our operator watched the situation develop, then activated deterrent systems and issued a direct voice warning through the speakers. The intruder stopped, looked around for the source of the voice, and left. Total time on-site: under four minutes. No theft, no property damage, no disruption to the renovation schedule the next morning.
Location: Pomona, CA
Trespasser Removed from Pasadena Commercial Property — June 2025
A woman living out of her car pulled into a Pasadena commercial property and parked overnight. She got out and started walking the lot, initially staying out of the main camera angles. ValleyGuard’s operators were tracking her movement across multiple camera zones. When she came back into clear view, our monitoring specialist issued voice warnings through the property’s speakers.
Multiple attempts to get her to leave voluntarily — she ignored every one. The property’s security guard approached her directly, and that’s when things got tense. She became confrontational and refused to comply. The guard backed off — the right call for his safety. Our operator contacted Pasadena Police and maintained close monitoring until officers arrived and removed the trespasser. No injuries, no property damage, no liability exposure.
Location: Pasadena, CA
Dealership Break-In Prevented in San Fernando Valley — March 2025
At around 3 AM, a grey sedan pulled up next to a San Fernando Valley auto dealership lot. Two individuals jumped out and walked straight toward the front entrance — armed with tools, ready to smash through the glass doors. They began breaking the glass, hoping to access vehicle inventory or sensitive customer information inside. Our monitoring operator spotted them the moment they stepped onto the property. A voice cut through the night air with the first warning: all activities were being monitored live.
The suspects paused and looked around the lot, but they weren’t done yet. Our operator delivered a second, more direct warning commanding them to leave the property immediately. Both guys ran back to their car and drove away. The dealership had to replace the front glass doors, but the alternative could have been far worse — stolen inventory, customer data theft, and weeks of insurance paperwork.
