With the invention of larger memory cards, like 256GB, you can record for weeks, especially when using motion-activated recording. Many new battery-powered nanny cams can record to a micro SD card that goes into the camera itself no more running wires back to anything! High-resolution recordings in 720P and 1080P HD are now possible. Now you log into your hidden nanny cam via an app on your smartphone to live view your camera from anywhere, playback video, and even save it to your phone! Nanny cameras now record 720P or 1080P high-resolution and live view in 1080P on most models. SD card storage has surpassed the older models that could only use 2,4 or 8 gigs, and now they support up to 256GB cards oh, and let's not forget video resolution. Video files are date and time-stamped so you know when an incident occurred. Some great features that have come out over the years for hidden cameras are that they can be set up to record upon motion or continuously. There was no viable solution for this back then, as internet speeds were too slow (dial-up), so the best you could do for live viewing was plug a TV into the VCR with your hard-wired camera, sit in front of it, and watch the screen all day. One of the biggest requests we would get was the ability to remote view a property and keep an eye on things while at work or on vacation. In those days, this just compounded the issues because cameras only output 420TV lines of resolution. You would have stacks of VHS tapes, or you would reuse tapes and re-record over them, and VHS was not the best format to keep writing over as it would cause degradation of the video playback as you continuously recorded over old footage. The size of the VHS tapes limited you to 4, 8, 24 & 48 hours. But there was a limitation in all of them: you had to run a cable from your hidden camera to a VCR to record video footage.

Back in the day, people needing to covertly capture video of suspected child abuse, drug abuse, infidelity, or theft had several options for different models of nanny cams.

I've been in the spy and security industry for over 16 years, and I've seen many advancements in the field of covert surveillance.

People generally use nanny cams to catch maintenance workers coming into the apartment unannounced, monitor how the nanny takes care of their children, document employee theft, or have a camera for security purposes when a complete hard-wired CCTV system is not possible.

First, I feel that I should provide a nanny camera definition: a video-only device with a camera and a recorder built into a functioning (or non-functioning) decoy items, such as a clock, AC adapter, or the one that everyone knows, a teddy bear.
