Whether you're upgrading an existing video recorder or thinking of purchasing a whole new Analog HD system, this latest 4K Ultra HD digital video recorder by Lorex meets all the demanding needs of modern-day security. Features such as 4K recording resolution produce visually accurate video footage with exceptional detail. Along with 4K recording, advanced person/vehicle detection and smart home compatibility, this DVR combines active security with the convenience of hands-free voice control.
Advanced motion detection Be alerted when motion is detected on your property with advanced motion detection capabilities. This system features person/vehicle detection on 4 channels to reduce unnecessary alerts and false alarms. Important motion events that are recorded can easily be found using the Smart Search feature, which organizes events by type (e.g. person/vehicle motion vs. general motion, etc.).
Panic button This DVR brings your security camera system to the next level with an easy-to-use panic button located on the front of the recorder. By pressing and holding this button you can activate all lights and sirens on your compatible Active Deterrence cameras at one time to deter potential intruders.
Remote viewing from your mobile with Lorex Home™ This feature-rich system is designed for use with our innovative, hassle-free Lorex Home™ app. Using Lorex Home, you can quickly and easily view your security system remotely from your smartphone or tablet and control active deterrence features. Simply download the free app, scan the QR code on the DVR and your cameras will appear for you to monitor (or review footage). You can also program the app to send you motion-activated push notifications and email alerts with screenshot attachments straight to your phone to keep you connected to your property at all times.
See the world in 4K 4K is the highest quality available for home security systems and this powerful DVR can record 4K (8MP) resolution video on all channels. The higher pixel count, when compared to 1080p, results in superior detail and definition with realistic color representation, so that objects in video are clearly outlined and easily identifiable, no matter how big or small.
Smart Search Find what you are looking for quickly with Lorex's Smart Search. Select an area of interest and automatically playback any video footage showing scene changes in that area. Ideal for doorways, drive ways, etc.
HEVC / H.265 video compression This DVR is able to receive HEVC (High Efficiency Video Encoding) or H.265 video compression files. This type of encoding can save up to 40% more space when compared to H.264 Advanced Video Coding. Please note that security cameras with HEVC video compression are required to take advantage of this feature.
Reliable security grade hard drive with no hidden storage fees DVRs such as this are capable of working 24/7 without a break. Thankfully, so is the 1TB hard drive within it. Lorex uses security certified hard drives that are manufactured specifically to meet the high workload demands of continuous security monitoring. This means that you can rely on this professional grade hard drive to safely store weeks (or even months) of security footage. It is also possible to manually upgrade the hard drive within the DVR to a hard drive up to 8TB in size. There are no surprise fees or monthly cloud subscription necessary because all recorded footage is safely stored on the built-in hard drive. Local storage also means that all your recordings are secure since only you can access your footage.
Automatic overwrite You don't have to worry about storage management with this DVR. It is designed to automatically overwrite the oldest data with the newest data when the hard drive becomes full. This means that you will never run out of storage space. Just make sure to save any important footage before it gets overwritten.
With or without the internet This DVR can be used without being connected to the internet. This means that your data can only be accessed directly from your DVR. However, an internet connection is required to enable remote viewing, motion push notifications, and to download the latest firmware updates.
 | The hard drives are designed to work in a security environment, including simultaneous recording & playback from various streams. |
