Product Description

Product Description

View anytime, anywhere with remote viewing via internet, smartphone, and tablet

From the Manufacturer

Trust DEFENDER® to make thieves and vandals think twice about approaching your property. DEFENDER® systems function just like a computer, with a mouse for pointing and clicking and an intuitive icon-based menu for easy set up and use. View anytime, anywhere with remote viewing via internet, smartphone, and tablet and receive email alerts, with photo, when motion is detected on your property. Record over 2 years’ worth of footage on the included 500GB hard drive. Connect up to eight cameras to this 8CH system and monitor your business or home inside and out. Don’t give thieves a chance. Stop them with DEFENDER®!



Extremely easy to set up and use

You’d expect a system that keeps such a close eye over all you hold dear to be complex. You’ll be surprised how easily this DEFENDER® system operates. It functions just like a computer, with a mouse for pointing and clicking and an intuitive icon-based menu that provides prompts and coaching to assist you in navigating the system. It’s even so simple to use it will begin recording as soon as it’s plugged in.

Crisp and detailed video you can rely on

Your security system is only worthwhile if you can actually see the person stealing from you. DEFENDER® DVR records in D1 resolution, which is the equivalent of 720 x 480 pixels or DVD quality. The resulting clear, crisp and accurate video feed will help put the criminal away.


View your camera footage from anywhere in the world

Everyone needs a vacation to get away from it all. With DEFENDER you can enjoy yourself with peace of mind, knowing you can view your camera footage live online, anytime and anywhere. On either a PC or Mac you can use such search engines as Internet Explorer® or Safari®. You can also view footage on almost any smartphone, including iPhone®, BlackBerry®, Android™, Windows Mobile®, or Symbian™, as well as on your iPad® and most major tablets. Whether monitoring your business or home, you will always feel in control.

Two years’ worth of footage storage – and more if you need it

The included 500GB hard drive allows continuous monitoring and recording of over two years’ worth of footage! Your DVR sends an alert when your memory space is full so that you can choose to overwrite old video or stop the unit from recording. The built-in USB port gives you the option of backing up and transferring your video footage with a USB flash drive or external USB hard drive. And if you need to expand your storage even further, you can choose to record only when motion is detected. This DVR uses H.264 compression which maximizes recording time, transfers data more efficiently over the internet and you’ll use 50% less storage space than traditional compressions - MPEG4, MJPEG - while still benefitting from high-quality imagery.

Instant email alerts if activity detected

You will instantly know if any suspicious activity is happening on your property. This DEFENDER® system is designed to send you an email alert, complete with photo, if any motion is detected on your property or if any of your cameras experience video loss. You’ll always be in the know, no matter where you are.

Lifetime Live Customer Support

Our customer support team can be reached by phone or by email and live web chat. You’ll always have access to an expert. Support is available in English, Spanish and French.

Our Windows XP based system was getting a little long in the tooth so it was time to replace it. Replacing the computer with this DVR was essentially "plug and play." As soon as power was applied it recognized the eight cameras and immediately displayed video.

It still requires one to customize their preferences and this takes a couple of hours plus subsequent "fine tuning" to obtain the desired results. For example, adjusting the motion detecting areas and motion sensitivity because bushes blowing in the wind will activate the recording.

The manual is adequate but it is very generic to all of their products but this wasn't a big deal.

I spoke to tech support twice and they were helpful and answered by questions.

It already paid off because someone hit our security gate resulting in more than $1,000 in damages and this person has been identified and has written a check for the damages.

This DVR is reasonably priced and I recommend it.

Well made, nice design, good features but getting through to customer service is difficult. I've been on hold for over an hour both times, but once I get to talk to a live person, they are great. The last time I called, after waiting 47 minutes, Michelle answered the phone. He was great, but, he had to put me on hold and had to transfer me to tech support. After 23 minutes hold time, I had to join life so I hung up and still have unresolved issues. They have training videos on line and documentation, but my issue needs tech support.

I was pleasantly surprised with this DVR. Works like a charm. Although it is very easy to setup, when I had a question and contacted support, their response was immediate and the service outstanding. I would highly recommend the product and the company.
