Product Overview

For those who demand ultimate peace of mind, Defender's 16-Channel Smart Security Cameras are designed to protect your home or office, keeping your building safe and crime-free. This system includes a 1TB HDD to provide up to 4 years of recording and advanced IR image filtering for color accuracy. The patented sleek, modern appearance of Defender cameras is complemented by its durable, vandal-resistant design that ensures hassle-free installation and functionality. Defender systems are ideal for protecting a wide range of outdoor applications and larger locations including building perimeters and parking lots.

  • 1TB HDD allows for continuous monitoring and can store over 4 years’ worth of recorded footage, maximizing available memory with motion-activated recording and H.264 compression technology
  • DVR alerts activate to notify user when HDD is full so you can backup and transfer footage to USB flash drive or external hard drive
  • Ultra hi-res, crisp, color-enhanced imagery with 600 TV lines of resolution; when lighting conditions are unfavorable, the advanced IR filter automatically activates to purify reds, greens, yellows and blacks that may otherwise appear washed out or faded
  • 110 ft. of hi-res night vision at zero lux; camera automatically activates infrared illumination with 38IR LEDs for clear identification of objects in complete darkness
  • Weather-tight design with IP65 rating means camera is completely protected from dust and typical adverse rain conditions; a sleek sunshade also protects from additional glare that can affect image quality
  • Adjustable anti-vandal wall mount allows installation at almost any angle for the best view; Allen keys enable secure adjustments so that vandals, elements or time cannot readjust the set angle
  • Anti-vandal bracket protects wires from damage or vandalism by ensuring no part of the wire is exposed when installed directly into the wall; if you experience video loss, an audible alarm will sound from your DVR
  • Meets general building codes and insurance requirements with fire-rated cables; each camera includes 65 ft. of pro FT4 rated black cabling for direct installation to walls and framework (please check local building code requirements and insurance policy)
  • Monitor remotely with Internet connection up to 7 secure user profiles may be created for your staff or loved ones enabling live viewing anytime, from anywhere via internet, smartphone and tablet with the Defender DVR
  • Review previously recorded footage from any computer with an Internet connection; email alerts with photo can be sent when unexpected motion is detected
  • 16 cameras let you customize each area and custom-name individual channels to easily identify the location; a masking feature lets you block out a portion of the scene from an individual camera such as a cash register or safe while still seeing activity around the masked area
  • Covert feature can protect an entire channel from public or user viewing so only authorized viewers can see activity in that location; other viewing options include full screen, quad screen, 9-channel view, 16-channel view and sequence switching; each recorded area is complete with time and date stamp so you can search by event
  • Ready to connect with up to 16 surveillance cameras for maximum monitoring both indoors and out; DVR is also compatible with PTZ camera
  • Easy to set up and use with menu that provides prompts and coaching to customize settings, while mouse or remote lets you navigate icon-based menu; it’s so simple it will begin recording as soon as it’s plugged in
  • Lifetime live customer support can be reached by phone, email and live web chat, available in English, Spanish and French
  • 1-Step Remote Viewing software application (available as a free download for PC and Mac) auto-networks your DVR in less than 5 minutes; simply input your DVR’s IP address (found in the menu) into the connection program on your computer, click “Sync to Router” and 1-Step will automatically do the rest

Customer Questions & Answers

Will this DVR work with the Night Owl 900 TVL Security Bullet Camera - Audio Enabled?

I would like to have at least one audio-enabled camera. Will this DVR work with a competitor's product (Night Owl Security Camera - Audio Enabled) or does it only allow to connect the cameras that are included in this set? If the Night Owl camera does not work, does Defender manufacture an audio-enabled camera that will be compatible with this product?
Asked by: Archer01
Hello Archer01, thank you for your inquiry. As long as the audio-transmitting camera has a BNC type connection for the DVR, you should have no issue with the connection. Defender does not manufacture a camera with an audio-pickup. Please check with your local regulations regarding the recording of audio. If it is prohibited in your area, any recording you make with audio attached could be rendered inadmissible if needed for legal purposes.

Would you, or Home Depot, come an install it in my house?

Rated 5 out of 5 by from Great Service: I had an older 8 channel dvr with 4 camera. It was nice and did the job. I added 4 more camera. I saw a friend of my who had the 16 channel system an the new iPhone alp for viewing: so I upgraded to a 16 channel system with a 2 TB hard drive and 8 camers. I can now review the camera recording from the phone. I had a problem and called Defender I got hold of Michel and explained the problem I was having. He had the problem resolved in about 10 min time. In the future If I have any problem I will ask for him, because it was like he was sitting next to me when he told me what to do.

Rated 5 out of 5 by from great system ! this is the best ! I got this system 7 months ago and how nice. Picture is so clear and great night vison also. Very easy to install and I'm just so happy with it. i have installed 5 of these for my friends also and tell people to only buy defender. This model is so good because having 8 camera's now and can add up to 8 more if needed. Every home is not the same so you can add camera's to cover all areas. the price is so fair for all you get. Just so happy with defender and this system.

Rated 4 out of 5 by from Works great! I bought this a couple of months ago and have enjoyed the benefits greatly. I started with the original 8 cameras and have since added a few inside as well. I now know that my pup sleeps the day away. The quality is good and the only downside is it was a bit tricky to upload footage.
