  • What's Included
  • The 21305 Sentinel Pro from DEFENDER is a professional quality security monitoring system for a home or office that can be installed by a DIY'er. It features a four channel DVR (digital video recorder) with a built-in 1TB HDD (hard disk drive) and four wireless 520TVL (TV lines) cameras. Each wireless camera pairs to a DEFENDER wireless receiver and each receiver will pair with up to two cameras with a communicating range up to 750 feet. Upon setup of the system you will have access to a variety of viewing options giving you full access to see your property whether you're home or away. Through DEFENDER's remote viewing software you can network the DVR to the internet so that you'll be able to view live camera feeds, watch recorded footage and receive motion activated email alerts from a smart device or computer anywhere in the world, provided an internet connection is available. Additionally, the DVR can be connected directly to a monitor or TV for viewing with the ability to custom name channels, view picture-in-picture, full screen, quad screen, zoom or set sequence switching. Setting up and navigating the system is quick with the included USB mouse or via remote control.


    Cameras

    The four wireless PHOENIX cameras included with this system are 520TV Line resolution cameras that will provide a clear picture of whatever is being monitored. Each camera is weather-resistant and IP65 rated to protect the camera from the elements year-round if being installed outdoors. Built-in to the cameras are 24 IR (infra-red) LEDs, per camera, which allow each to see up to 100 feet away in complete darkness. The infra-red LEDs do not emit a visible light either so while they're monitoring your property at night they will also stay completely hidden and out of sight. Vandal-resistant mounting hardware is also included with each camera which allows for a secure mount on just about any indoor or outdoor installation.


    Receiver Included with this system are two PHOENIX wireless receivers that connect with up to two wireless PHOENIX cameras a piece. The PHOENIX receiver has a transmission range up to 450 feet and an optimum transmission range up 150 feet allowing for a large radius in which connected cameras can be setup and still communicate with their respective receiver. LED status indicator lights on the front of the unit will let you know if the receiver has power and the receiver will also provide out of range alerts if it is no longer receiving a signal from a connected camera.


    DVR The brain of this system is the DVR which records footage of all the connected wireless cameras and allows for live viewing of each camera feed. This high-powered DVR has a large 1TB hard drive which gives it the ability to store up to four years-worth of video footage that can be easily played back if ever needed. Setup of the DVR is quick. It connects to a monitor or TV with a VGA or HDMI cable and then lets you customize the system to your needs via a remote control or included USB mouse. The system provides options such as setting up email alerts upon motion detection, event searching and area masking (blurring out of faces or objects such as the combination lock to a safe). Once connected to a monitor or TV, a handful of viewing options will also be at your disposal such as picture-in-picture, full screen of a selected camera, quad screen, eight channel view, zoom and sequence switching. Included 1 Step remote viewing software will also allow for viewing of live camera feeds, watching saved footage and receiving of email alerts from a computer or smart device with an internet connection.
