Frequently Asked Questions

DOES DEFENDER PROVIDE FREE SHIPPING?

We are proud to offer free ground shipping to our customers across the 10 Canadian provinces with no minimum purchase required. Free shipping is not available for the Canadian Territories and select areas considered remote by our shipping partners. Shipping fees will be calculated at the Checkout. Estimated delivery is 3-7 business days.

WHAT IS THE RETURN POLICY?

Not what you were expecting? Our no-questions-asked return policy makes it easy for you request a return within 30-days of placing your order. Please Note: Original shipping charges will not be refunded and return shipping costs are the responsibility of the customer.

WHAT IS DEFENDER'S PRICE MATCH GUARANTEE?

See a lower price on this item from an authorized retailer? Contact our Support Team here or chat live Monday to Friday from 8am-4pm EST with a link and screenshot to the advertised price and we will match it! Conditions apply. Learn more here.

ARE THESE 4K SECURITY SYSTEMS WIRELESS?

No. As most of our 4K security systems have more than 4 cameras, if they were to be wireless there would likely be interference and lag issues. To ensure an interference free experience and give you the option not to use W-Fi, our 4K Security Systems are a wired connection between the cameras and DVR.

WHAT IS THE DIFFERENCE BETWEEN 4K (8 MEGAPIXEL) AND 2K (4 MEGAPIXEL)?

8 megapixel, also referred to as 4K resolution, is double the clarity of a 4 megapixel (2K resolution) security camera! By investing in 4K resolution, the amount of pixels in your image is doubled, which gives you superior detail and allows for a higher quality, undistorted zoom.

CAN I ALLOW OTHER PEOPLE TO VIEW MY NVR REMOTELY?

Yes. You can share your Defender Empower App access with up to 20 additional users. Each user must download the Defender Empowerment App and create their own account before sharing access.

CAN I VIEW MY LIVE OR RECORDED FOOTAGE FROM A WEB BROWSER?

No. We do not offer web viewing. You can view the footage from the free Defender Empower App with compatible iOS/Android smart phones/tablets, and through a TV or monitor connected to the NVR.

CAN I EXTEND MY CAMERA’S ETHERNET CABLE?

Yes. You can extend each camera to a maximum of 180 feet. We recommend using Defender’s certified authentic and genuine Ethernet cable when doing so.
