Faulty cameras

Corne Delport from CFC Security Projects did a camera system installation for my preschool in March 2022. The installation was great, his team worked well. Since then, there have been continuous issues with faulty cameras. Corne did change them once and since November 2022 when the same issue presented itself with faulty cameras, Corne has done nothing but ignore my calls and messages. I would be very wary using him and his company.
