Security Bulletin: Laptop Thefts on Campus

Over the past few weeks, we have had an increase in thefts on campus. Since mid-June, five laptops and 10 bicycles have been stolen from campus.

One laptop was stolen from a secured vehicle in the Holliston parking structure; two laptops were stolen from public areas, including from a public event held in Cahill; and two laptops were stolen from offices. Bicycles continue to be a target of thieves, not only on campus, but also around the City of Pasadena.

The incidents on campus appear to be occurring primarily during the week, in the late afternoon and evening hours. Currently we have no suspect description. However, Caltech Security is working with the Pasadena Police Department to locate the stolen items, and with Pasadena Police and Pasadena City College Police to reduce the occurrences on and around campus. Caltech Security has increased both foot and vehicle patrols around campus.

Please contact Security at (626) 395-5000 (or x5000) to report any suspicious activity. Do not confront any suspicious persons on campus. Instead, call Campus Security immediately. Your safety is our primary concern. Items can be replaced so DO NOT attempt to contact or confront anyone you suspect is engaging in suspicious or criminal activity.

As a community we share the responsibility of securing property, doors, and reporting suspicious activity. We are asking for your help in making the campus as safe as possible by taking the following steps:

  • Report suspicious activity to Security immediately.
  • Secure your valuables in locked compartments.
  • Lock your office doors when leaving for any amount of time.
  • Do not leave personal items unattended.
  • Report individuals who “tailgate” or enter secure buildings and restricted areas without keys or the proper credentials by slipping in behind someone else.
  • Do not prop open exterior doors.
  • Trust your instincts. If someone or something makes you feel uneasy, get out or get away and call Security immediately.

If you need emergency help, call x5000 on campus or (626) 395-5000 if you are off campus, or call 911.

—Vic Clay, Chief, Campus Security

Caltech Secure Wi-Fi Project Update

The IMSS Wi-Fi project team is on track to upgrade over 70 buildings and 2 million square feet by summer 2019. With 1,200 additional access points installed so far, more than 6200 devices are connecting to our wireless networks weekly. Apple devices account for 65% of clients connected, and a normal day sees close to 5TB of data delivered. We are currently working in Broad and Beckman Institute.

As we transition buildings from Beavernet to Caltech Secure, our team works with the building manager to make sure the changes are communicated to occupants and provides onsite assistance for those who need help connecting their devices.

One big change is that we now require people using Caltech Visitor to provide their mobile number before they can connect to the wireless network. Individuals enter their U.S. mobile number with the leading digit “1” and then receive a text message with a code they can use to connect. Additional instructions for connecting to the wireless networks can be found here.

We are currently working in Broad and Beckman Institute, and will announce the next buildings once funding for FY2020 has been finalized. For project map and updates on the project schedule, please visit

To connect to the Secure network in areas where it is already active, select Secure and use your Access password. For more information, visit the Caltech Secure and Caltech Visitor information pages.

For help or more information about the project, contact the Help Desk at extension 3500, email, or visit Caltech Help at
