Lorex 4KSDAI168 4K Ultra HD 16-Channel IP Security System with 8 Smart Deterrence 4K (8MP) Cameras, Smart Motion Detection and Smart Home Voice Control (M. Refurbished)

The next generation of security monitoring is here. With industry-leading 4K (8 megapixel) resolution, smart deterrence and motion detection, this security camera system from Lorex will bring a whole new level of detail to your security monitoring. It includes our outstanding 4K, 16-channel N861 Series Smart Detection Network Video Recorder (NVR) and eight 4K Smart Deterrence Security Cameras. If you are looking to protect your home, small business or commercial property, this powerful security camera system will have you covered.

4K sharpness gets you the details you need Thanks to the camera's powerful 8MP image sensor, you'll experience the difference that 4K resolution makes when it comes to your security. 4K means there are more than 8 million pixels, and that results in sharper video, realistic color representation and superior digital zoom capabilities.

Person and vehicle smart motion detection Your cameras come with advanced person and vehicle detection on up to 8 channels that helps identify more important objects that enter the camera's field of view. Thanks to this innovative feature, you will only get a push notification and image screenshot to your Lorex Home app whenever a person or vehicle is detected on your property. This effectively reduces the number of unwanted false alerts caused by moving branches or animals. All recorded motion alerts can easily be reviewed by using the Smart Search function in the Lorex Home mobile app.

Stop trespassers in their tracks with Smart Deterrence Super bright LEDs, a remotely triggered siren, and two-way audio make this security camera an extremely valuable asset to your IP security system. For example, the LED lights can be customized to always be on or triggered by motion. You can also choose a strobe light setting, in addition to setting a schedule for when the deterrence LEDs should automate. The remote-triggered siren is also designed to stop trespassers right in their tracks. When motion is detected within the sensor range, the system sends an alert to your Lorex Home app, allowing you to remotely access the camera and set off a loud siren to deter crime.

Listen-in Audio and Two-Way Talk A built-in speaker and microphone allows for crystal-clear audio functionality. Listen-in audio recording will add a whole new dimension to your overall security monitoring, as it can provide additional details (like a voice) should an incident occur. This camera also has a speaker that allows you to communicate with others through the camera through the Lorex Home app. * *Audio recording is disabled by default. Audio recording without consent is illegal in certain jurisdictions. Lorex Technology does not assume liability for any use of its products that fails to conform with local laws.

Capture the best images with HDR These cameras use HDR (High Dynamic Range) technology to ensure every important detail is captured, regardless of the lighting conditions. HDR automatically adjusts the brightness in areas that are either too dark or too over-exposed to decipher details. The result is improved, highly detailed video footage that looks uniform throughout.

H.265 / HEVC encoding Your security camera and NVR are both equipped with High-Efficiency Video Encoding (HEVC) or H.265 video compression. This encoding technology efficiently compresses file sizes. In fact, it can compress file sizes up to 50% more than files using the previous encoding technology (H.264), without any noticeable degradation in quality. HEVC encoding will also save you plenty of bandwidth while watching live or recorded video remotely.

Built for the outdoors While this camera is suitable for both indoor and outdoor use, it has been especially designed to withstand the harsh impacts of nature. It has an IP67 rating, meaning it can tolerate extreme temperatures ranging from -4°F to 122°F (-20°C to 50°C). It also has a durable, all-metal sheath for added protection.

Panic buttonThis NVR 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 system is designed for use with our innovative, hassle-free Lorex Home™ app. With Lorex Home, you can quickly and easily view your security system remotely through your smartphone or tablet. 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. Simply download the free app, scan the QR code on the DVR and your cameras will appear for you to monitor (or review footage).

PoE technology for simple plug-and-play installation Power-over-Ethernet (PoE) technology is an all-in-one solution that cuts cost and installation time. A single cable run between your NVR and IP camera provides both power and video transmission so you don't have to install your camera near a plug.

Area searchFind what you are looking for quickly with Lorex's Area Search. Select an area of interest and automatically playback any video footage showing scene changes in that area. Ideal for doorways, drive ways, etc.

Reliable security-grade hard drive preinstalled A 3TB security grade hard drive (expandable up to 2 × 8TB) comes preinstalled within this NVR. Designed to meet the high workload demands of continuous security monitoring, this heavy-duty hard drive can reliably record weeks (even months) of footage without taking a break. All recorded footage is then safely stored on the hard drive where only you can access it, so there are no surprise fees or monthly cloud subscriptions.

Two storage bays This NVR comes with two separate hard drive bays. Each of which can be upgraded with a hard drive up to 8TB, giving you the potential for a total of 16TB's of storage space. You can also use the second hard drive to record videos in parallel with the primary hard drive. This way, the footage is automatically backed up if the recording hard drive fails

With or without the internet This NVR can be used without being connected to the internet. This means that your data can only be accessed directly from your NVR. However, an internet connection is required to enable remote viewing, motion push notifications, and to download the latest firmware updates.
