Security cameras started in wartime labs, moved into banks and businesses, and now live on our phones. The very first closed-circuit system appeared in 1942 for rocket testing. Commercial units reached the public in 1949, and adoption snowballed from there.
When Did Security Cameras Come Out? 🕒
The earliest known CCTV was deployed in 1942 to monitor Germany’s V-2 rocket launches. In 1949, the first commercial CCTV system became available for civilian use, initially in industrial sites, banks, and government facilities. Through the 1960s and 1970s, analog cameras and tape recorders pushed CCTV into retail loss prevention, then by the 1990s digital recording and multiplexers made multi-camera installs practical at scale.
Why This History Still Matters Today
Knowing where CCTV began helps you choose smarter today. Early cameras recorded low-resolution analog footage on tape. Modern systems deliver 4K clarity, color night vision, and AI motion alerts on your phone. That jump changes how you place cameras, how many you need, and what you can prove when something happens.
-
Better optics and higher resolution let you identify faces and plates instead of just “seeing motion.”
-
Solid-state storage means months of continuous recording without juggling tapes.
-
Mobile apps give instant alerts and two-way audio so you act in the moment, not after the fact.

The Milestones That Shaped CCTV
The path from lab experiments to doorbell cams came through five practical shifts: purpose, storage, optics, networking, and intelligence.
-
Purpose: from monitoring to evidence
The 1940s and 1950s focused on live monitoring. As video recorders matured in the 1960s, footage became evidence, not just observation. -
Storage: from reels to SSDs
Open-reel and cassette recorders demanded daily swaps. DVRs in the 1990s cut labor. Today, NVRs with terabytes of storage and cloud archives make retention policies easy to enforce. -
Optics: from tube sensors to high-def CMOS
Analog tube sensors struggled in low light. Now, back-illuminated CMOS, wide dynamic range, and IR LEDs make night scenes usable. -
Networking: from coax to PoE and Wi-Fi
Coaxial cable ruled for decades. Power-over-Ethernet simplified wiring and scaling. Wi-Fi brought DIY convenience, though PoE still wins for reliability. -
Intelligence: from motion to smart detection
Crude pixel motion triggers created false alerts. Today’s onboard analytics recognize people, vehicles, packages, and zones.

Practical Placement That Actually Works
-
Front entry at head height so faces are not shadowed by caps.
-
Driveway with a plate angle of 20–30 degrees to read plates at night.
-
Backyard corners for cross-coverage instead of a single center post.
-
Inside, aim down hallways where people must pass rather than wide open rooms.
Tip: Use one camera optimized for faces at the door and a second for plates at the curb. Trying to cover both with one lens usually fails when you need evidence.

Storage That Matches Reality, Not Hopes
-
Retention target: Most homes want 14–30 days. Businesses often need 30–90.
-
Resolution math: 4K consumes more storage, but newer codecs like H.265+ help.
-
Smart recording: Schedule business hours continuous, off-hours motion or AI events only.
-
Redundancy: Mix onboard SD cards for short-term failover with NVR and optional cloud.
Simple estimate: For 6 cameras at 4K with moderate motion, a 4–8 TB NVR often delivers 2–4 weeks. If you add a busy street cam, budget more.
Audio, Apps, And Alerts People Actually Use
-
Audio: Check state laws and site notices. If permitted, enable doorbell or porch audio for deliveries and confrontations.
-
Apps: Prioritize human or vehicle detection and quick clip sharing.
-
Zones: Mask sidewalks to cut false alerts.
-
Shared access: Give temporary app access to contractors and revoke on finish.

Which Option Is Best For You Right Now?
Apartment or rental
Pick Wi-Fi cams with privacy shutters and local microSD so you are less dependent on subscriptions. Use reversible mounts.
Starter home or townhouse
Go PoE 4K for door, driveway, and backyard. Add a compact NVR and enable cloud clip backup for incidents.
Larger house or small business
Deploy a PoE switch in the comms closet, 8–16 channels of 4K cams, and an NVR with RAID or redundant disks. Separate “face” and “plate” roles for critical entries.
Warehouse, yard, or parking lot
Use multi-sensor or PTZ for coverage, plus fixed 4K for evidence. Consider color night vision and white-light deterrence schedules.
Real-World Examples You Can Copy
-
Package theft reduction: A homeowner placed a 2.8 mm door cam for faces and a 6 mm curb cam for plates. With AI person alerts, they cut false notifications by blocking the sidewalk zone. When a package went missing, clear facial and vehicle detail resolved the claim the same day.
-
SMB after-hours break-ins: A shop owner scheduled continuous recording 8 a.m. to 8 p.m. and person-only events overnight. Storage covered a full month with a 6 TB NVR, and cloud clips preserved incidents for insurance without handing over the entire archive.
-
HOA parking control: Fixed cams watched entrances while a PTZ toured high-risk rows. License plate snapshots during the PTZ’s dwell spots produced enforceable logs without recording every lane 24x7.
Common Pitfalls To Avoid ❌
-
Mounting too high. Ten-foot soffit cams look impressive but fail to capture faces. Stay near eye level at entries.
-
One camera for everything. Use specific roles. A plate cam should be narrow FOV.
-
Wi-Fi only for large properties. Use PoE for reliability.
-
No signage. Proper notice may be legally required and also deters incidents.
-
Ignoring uplink. Remote streaming needs upstream bandwidth. Balance clip length and quality.
Cost And Value: Spend Once, Not Twice
-
Entry kits: 2–4 PoE cameras with 2–4 TB NVR start in the low hundreds.
-
Mid setups: 6–8 cameras with 6–8 TB NVR land in the mid range.
-
Pro installs: 12+ cameras with RAID NVR and mixed optics cost more up front but prevent replacement cycles.
Money saver: Go 4K where evidence matters and 2K in low-risk zones. That spreads the budget without losing what counts.

Frequently Asked Questions
When did security cameras become common?
They became widely common in the 1970s and 1980s as analog cameras paired with time-lapse VCRs and multiplexers, which finally allowed multi-camera recording on a manageable budget. Earlier decades focused on live monitoring in banks and government. By the 1990s, DVRs reduced labor and improved reliability, accelerating adoption in retail, parking, and campuses. The 2000s brought IP cameras and PoE, which pushed CCTV into mainstream homes.
Did they have security cameras in the 70's?
Yes, the 1970s saw practical analog CCTV with VCRs used for retail loss prevention and facility monitoring, though image quality was limited and tape swaps were frequent. Time-lapse recorders stretched tapes to cover longer periods. Systems were expensive and not yet common in homes, but banks, casinos, and factories relied on them for incident review and policy enforcement.
Were security cameras a thing in the 80s?
Absolutely, the 1980s expanded CCTV with multiplexers and switchers that handled multiple camera feeds, which meant broader coverage of malls, parking garages, and public spaces. Cameras became smaller and more reliable, cabinets held coordinated recording gear, and security rooms standardized on several monitors. Although still analog, operational scale and deterrence value both grew significantly in this decade.
Were there security cameras in 1999?
Yes, by 1999 many businesses and public agencies had transitioned to early DVRs and better optics, making it easier to search archives and produce usable evidence. Multiplexed views and PTZ control were normal in control rooms. Residential systems remained less common due to costs, but convenience stores, banks, and campuses widely used fixed and PTZ analog cameras feeding DVRs.
Were there security cameras in the 90s?
Yes, the 1990s were a turning point with digital video recorders replacing tape and improving retention and search. Image quality improved, and multi-site monitoring began to resemble modern workflows. PTZ domes appeared more often in public spaces, and long-run coax infrastructure matured. By the decade’s end, IP experiments laid the groundwork for the 2000s PoE boom and the smartphone-first experience we expect today.
