101AV 5MP 4in1 HD Dome Camera 2.8-12mm Varifocal Lens - Night Vision

In this review the 101AV 5MP 4in1 HD Dome Camera is evaluated for small businesses and homeowners who need a flexible, high-resolution surveillance camera without a complex install. The bottom line: it delivers crisp 5MP daytime images and usable night vision at a competitive price, and its 4 in 1 compatibility makes it a practical choice when integrating into a variety of DVR systems. Setup requires attention to the default HD-TVI mode, but once matched to the recorder the camera provides stable, detailed coverage for entrances, offices, and common spaces.

Key Features

• 5MP resolution: The 1/2.8" 5MP CMOS sensor captures 2592x1944 images for noticeably sharper surveillance video than 1080p options.
• 4 in 1 compatibility: Switchable between 5MP TVI/AHD, 4MP CVI and CVBS 960H to work with most DVRs, reducing compatibility headaches.
• 2.8-12mm varifocal lens: The adjustable lens lets installers choose a wide-angle view or tighter coverage without swapping optics.
• Smart IR 100ft range: Four IR LEDs with ICR day/night filter provide usable night monitoring and clearer details in low light.
• Dual voltage power: Accepts DC12V or AC24V for flexible wiring options in different installations.
• Durable dome design: Vandal-proof and weather-resistant housing allows indoor or outdoor mounting on ceilings or walls.

Who It's For

The camera is a good match for small businesses, retail shops, and homeowners who need a reliable dome camera with high-resolution daytime images and flexible system compatibility. Installers who value a single camera that can be reconfigured to work with different DVR standards will appreciate the 4 in 1 capability and varifocal lens.

Those looking for a plug-and-play IP camera, cloud connection, or advanced analytics should look elsewhere; this is an analog HD line camera intended for local DVR systems and on-premise recording rather than network-first setups.

Pros & Cons

Pros

• 5MP sensor delivers detailed daytime images that improve identification and coverage.
• Switchable TVI/AHD/CVI/CVBS modes make it versatile for mixed systems and upgrades.
• Varifocal 2.8-12mm lens provides useful framing flexibility for entrances and corridors.
• True day/night ICR and Smart IR give solid low-light performance up to about 100ft in favorable conditions.

Cons

• Default HD-TVI mode requires manual switching if your recorder uses a different format, which adds a small setup step.
• Not an IP/NVR camera, so users wanting cloud features or remote management should choose a network camera instead.
