Bangladesh has seen a rapid expansion of surveillance technologies in recent years under the banner of strengthening public security. CCTV networks, facial recognition systems, phone signal tracking devices and biometric databases are gradually becoming integrated into state operations. Yet little is publicly known about how these tools are used, who controls the data, or what legal safeguards exist to prevent abuse.
Thousands of cameras have already been installed across Dhaka and other major cities. Officials often highlight their benefits in crime prevention and traffic monitoring. However, there are also indications that many of these systems are being upgraded or prepared to be upgraded with facial recognition capabilities. Questions such as where the footage is stored, how long it is retained, and who can access it remain largely unanswered. As a result, it is becoming harder to draw a clear line between legitimate security measures and potential intrusion into citizens’ private lives.
Beyond visible cameras, more discreet surveillance technologies are also making inroads. International reports indicate that law enforcement agencies in Bangladesh have procured mobile phone interception and Wi-Fi sniffing equipment. Devices such as IMSI catchers can mimic cell towers, tricking nearby phones into connecting to them. This allows authorities to collect device identifiers, movement patterns and location data often without the user’s knowledge. Experts warn that such tools, if not strictly regulated, can easily be used to track activists, journalists or social media users who express critical opinions.
Biometric data collection has also become widespread across multiple sectors. Fingerprints, facial photos and iris scans are now routinely taken for national IDs, passports, SIM card registration, bank accounts and even school admissions. However, there is no publicly available framework outlining how many biometric databases exist, whether they are interconnected, or what level of consent citizens have in providing such information. While technological capacity is expanding, the mechanisms for data protection and accountability remain unclear.
Observers argue that surveillance technologies are not inherently incompatible with democratic governance, but their use must be transparent, legally defined and subject to oversight. Otherwise, they risk shifting from tools of safety to instruments of control, enabling the state to not only monitor crime but also influence behaviour and suppress dissent.
Bangladesh still lacks a comprehensive assessment of how far its surveillance apparatus has spread. Yet procurement records, import data and local field evidence suggest that a digital monitoring infrastructure is steadily taking shape. Without clear legal boundaries and public scrutiny, this evolution may soon become one of the country’s most consequential debates on freedom, security and the right to privacy.
