Motion Detection, Alers, and VCA

Motion Detection, Alerts, and VCA

This Admiral NVR is a motion detection NVR. Feel free to read more about these features by clicking on the link, but here's a quick synopsis:

Alerts and Notifications:

Get email alerts of motion detection alerts or VCA events

Set a schedule to get emails only on the hours of the day you want.

Get Push Notifications to the SCW Go Application for Android and iPhone.


Create your own customizable record schedule, including recording based on the day of the week, hours of the day, or even choose not to record for periods of time. Set constant recording during business hours and only motion during closed hours.

Motion, VCA, or 24/7 Recording - Record based on motion detection, VCA (video content analysis), or set the system to record 24/7. You can even record based on alarm inputs!

Motion Detection You Can Use in Court - If your system is set to record based on motion or VCA events, you can have a 60 second pre-event buffer to grab footage prior to the detection. You can also set the system to record up to 10 minutes after an incident is detected. Motion detection footage does not "time out" and stop recording mid scene. Motion Clips cannot be deleted by employees or other users.

Customizable Motion Detection Recording through VCA events:

VCA features vary by camera model, and can include:

Intrusion Detection - Monitor areas with precision, define zones, set time thresholds, and sensitivity.

Line Crossing - Create virtual lines to detect people or objects crossing doors, entrances, and more.

People Counting - Determine how many people are entering and exiting. Keep and review daily logs.

Audio Detection - Listens for Rises or falls in volume, and sudden loud noises.

Vandal Detection - Get alerts based on tampering detection, defocusing, or any dramatic scene changes.


Smart Search - Quickly review footage by filtering by motion detected in specific areas of the screen, by the face captured, by intrusion into certain areas, or by line crossing

People Counting Statistics - view traffic stats on your NVR or download a CSV file

commercial grade

Commercial Grade Features

This Admiral 4 Channel NVR is part of our commercial grade NVR line. Feel free to read more about these features and what commercial grade means to us, but here's a quick synopsis, as to how it relates to NVRs:

Surveillance Rated Hard Drive - NVRs need Surveillance Rated Hard Drives, as PC drives will overheat and fail.

Store 40% more data with H.265 video compression or switch back to H.264, if you need H.264 third-party integration support.

Passes vibration and surge testing up to 6,0000 volts - SCW NVRs can withstand vibration and surges up to 6,000 volts.

Cyber Security Protections - hackers can't easily see SCW cameras because they run on a special, isolated network created by the NVR. (For more information and a history of some of the larger cyber security attacks that have affected the industry, please see our guide on best practices for preventing IOT hacks.)

4K at 30 FPS Capable - Sufficient Bitrate (processing power) to Record Smooth Video

Easy 1 Click Firmware Update Process - Maintenance made easy.

750 Foot POE Extended Transmission: the old 300 foot limitations are a thing of the past.

No Recording Delay - Even when recording on motion.

ONVIF compliant - this NVR complies with the open industry standard ONVIF for both Profile S (video & audio streaming) and Profile Q POE ports (you can plug-and-play with other Profile Q compliant cameras).


3 or 5 Year Warranty

The Admiral 4 Channel NVR comes with a 3 year warranty. This warranty can also be upgraded to a 5 years. We recommend doing so for commercial clients.

SCWGo Smartphone and Tablet Apps

SCWGo is availible for both Android and iPhone/iPad.

vga output


This recording device has VGA Out.

You can plug this recording device into any VGA enabled monitor.

Q: Do I have to use a monitor?

A. No, you can use either a monitor or a TV, as explained below. But, you don't actually have to use either. You can manage nearly all your settings remotely via our PC or Mac apps or via the web-interface. Quite a few of our customers hide their recorders or put them in a safe with a cable pass-through, to prevent them from potential theft. This is a perfectly fine solution. You will probably want to plug a monitor in to make your initial setup easier.

hdmi output


This recording device has HDMI Out.

You can plug this recording device into any HDMI enabled television. This means that you don't need to purchase a monitor unless you want to; you can connect a monitor with either HDMI or VGA cable.

Q: What if I plug in both the HDMI and VGA? Can I watch on two screens?

A. On the Admiral 4 Channel NVR HDMI and VGA can both be used at the same time. Both outputs will display the same (mirror) image.

Please note that although our NVRs can all do 1080P and 4K output, all of them ship with 720P as the default. This is to prevent display issues for people who have older TVs or monitors that don't support 1080P or 4K. To change the output right click and then go to configuration.

American-Based Technical Support after the sale. For FREE. Forever.

Real review from Fransisco, who had this to say:

The most important part of a purchase like this is the support for technical assistance when there is a question or when there is a problem, and they always exceed expectations!

All of our equipment comes with Free Technical Support that is US based (Our Warehouse and Staff are located in Asheville, NC). We're happy to help you via chat, email, screenshare / remote support sessions, and phones. Our number is 866-414-2553 and we're open from 9-7 M-F (EST).

UL Listed

UL Listed and FCC Certified

This product is UL Listed and FCC certified

UL is a safety consulting and certification company headquartered in Northbrook, Illinois and provides safety-related certification, validation, testing, inspection, and auditing of SCW products.

The Federal Communications Commission has certified that the electromagnetic interference from the device is under limits approved by the FCC.

Not Sanctioned. On Oct 7th 2019, The US government placed sanctions on major providers in the industry for human rights abuses. Some or all Honeywell, Hikvision, Dahua, Lorex, Swann, LTS, Annke, Alibi, Laview, WBox, Interlogix, Flir, Bosch, ICRealtime, QSee, Panasonic, ADT, Indigo Vision, Montavue, and many more security products are included. SCW's Admiral and Imperial line equipment is not sanctioned.

These sanctions prevent these companies from using US technology or standards in future software or firmware releases and from using US patents in future hardware models. This means that they are going to face a situation where they either don't update firmware for cyber security concerns or lose ONVIF compliance or features when their firmware is updated. For these reasons, we recommend staying away from these brands.

For more information and full documentation, please see our article on NDAA and US Sanctions of Hikvision, Dahua, and their OEM brands.

NVR Mounting Options

nvr on desk

Shelf / Desk Mounting NVRs

This is what most people do: just put it on a shelf or desk. This makes it easy to connect to a TV/monitor and use the mouse (included) to control the NVR.

nvr in rack mount

Rack Mounting NVRs

Companies often want to put the NVR in their server rack room. People who do this often to control the NVR only through our apps or web browser. Most of our NVRs (8 channels and up) are wide enough to be rack mounted in a standard 19" server rack. We carry two options: the 9U Rack Mount Cabinet and the 12U Rack Mount Cabinet.
Our smaller NVRs can use our Cantilever Rack Mount Shelf.

nvr in wall mount

Wall Mounting NVRs

Many people choose to mount their NVR vertically on a wall near a TV. To do this for the Admiral 8, 16 (standard), or Corporal models, you will want to purchase a 1U Vertical Wall Mount Rack that matches the height of your NVR. You will also need to purchase the 1U Rack Mount Ears for these models.
The Admiral Pro 16, 32, and Imperial 32, 64 channel units have a height of 2U, and can be wall mounted with the 2U Vertical Wall Mount Rack. The 2U Rack Mount Ears are included with these models, but additional pairs may be purchased here.
The Imperial 128 channel is 3U. NVRs are heavy and you will want to make sure your wall can support the weight.
Our 4 channel NVRs cannot be wall rack mounted with a tray.

nvr in attic

Mounting NVRs behind a Wall / in an Attic

People who are afraid of the theft of an NVR often place it behind a false wall or in an attic. People who do this control the NVR only through our apps or web browser. Be aware: Not all attics are insulated well enough to be within the temperature requirements of the NVR. Temperature range is listed on each NVR's technical specs tab.

nvr in lock box

"NVR" Lock Boxes

There's a few companies advertising "NVR Lock Boxes," but any Server Rack or Computer Rack will do. Most Server Racks or Mounts have locks on them already. This picture is of a Tripp Lite Server Rack with Lock It houses a 32 channel NVR, two of our POE Switches, and a router, but there are tons of companies selling small server racks online.
