The Viewtron LPR-IP4 is an LPR camera (license plate recognition camera) with built-in ANPR / ALPR software, IR night vision, motorized varifocal lens, and PoE. The LPR-IP4 is a 4 megapixel IP camera with power over Ethernet support. This license plate recognition camera is enclosed in a IP67 rated weatherproof housing so that it can be installed in wet and cold climates. The built-in IR LEDs provide infrared illumination up to 300 feet. This is our
best LPR camera by far.
The 8-32mm motorized zoom / vari-focal lens provides an adjustable 18° - 46° field of view. This enables effective license plate capture between 7 to 30 meters (21 to 90 feet)
. The auto-focus motorized zoom lens can be adjusted from the NVR or mobile apps (iPhone and Android). The tri-axis bullet mount gives installers a lot of flexibility to adjust the angle of the camera. This IP security camera is ONVIF protocol compliant so that it can be used with any ONVIF compatible NVR, however in order to use the LPR software, you must use a
Viewtron IP camera NVR or configure the AI software functions by directly logging into the camera through a web browser.
When this LPR camera is used in conjunction with a
Viewtron NVR (network video recorder), it is capable of automatic license plate recognition (ALPR). This specialized software automatically detects and matches all of the numbers and letters on plates. CCTV Camera Pros is currently designing most of our LPR camera systems with this camera and a Viewtron NVR. It is the best solution that we currently offer, and by far the best value.
LPR camera system video demo to see how well it works. We also have these image snapshots captured from the Viewtron NVR that we used for testing. You can learn more about best practices for installation here.

The above image shows the dimensions of the LPR-IP4 in millimeters. For reference 100.3mm = 4 inches. 88.9mm = 3.5 inches. 279.5mm = 11 inches.
This is an IP67 rated security camera. The weatherproof housing provides 100% protection from dust and 100% protection from water intrusion. This camera can safely be installed outdoors in areas that have a extremely heavy rain and high humidity. It can also be installed in very cold climates and along ocean coasts where there is salt water in the air.
The camera body is made with high quality, corrosion-proof alloy aluminum. Stainless steel mounting screws are included for installation. CCTV Camera Pros highly recommends IP67 security cameras for outdoor installations. You can learn more about
IP67 cameras here.
Junction Box Mount Option
VT-J302 security camera junction box is an optional installation mount for the LPR-IP4. There is a bottom and side cable inlet and the cable leads from your camera can neatly be concealed inside this weatherproof enclosure. When the bottom inlet is used, the inlet plug can be moved to the size inlet. This junction box can be used for vertical or horizontal installations.
Here is the LPR-IP4 installed on a pole using the optional VT-J302 junction box. Pole installations are extremely common for LPR cameras. CCTV Camera Pros recommends using the junction box for almost all installations.
Please note that a lot of our
LPR camera videos were made with the 2 megapixel model (LPR-IP7). This was before the LPR-IP4 (4mp LPR camera) was available. The 4mp LPR-IP4 has all of the same automatic license plate reader functions.
The difference is that the new LPR-IP4 is a 4 megapixel resolution IP camera and it has a larger lens, 8 to 32mm instead of 7 to 22mm. It also has a higher powered infrared night vision so it is capable of capturing plates up to 30 meters / 90 feet away (using best installation practices). The IP67 weatherproof housing is the exact same as the 2mp model.
License Plate Detection Software
This video was recorded using the latest LPR-IP4 camera (the new 4mp model on this page). In this video, CCTV Camera Pros demonstrates the license plate detection software with the camera's lens set to the widest angle. The license plate detection zone is setup on the NVR from to 25-40 feet in front of the camera. The motorized vari-focal lens of the LPR-IP4 is set to the 8mm setting. The license plate detection software works excellent with these settings for both front a rear license plates, as you can see in the video.
Automatic License Plate Recognition
Here is another video that was recorded using the latest LPR-IP4 camera (the new 4mp model). In this video, CCTV Camera Pros demonstrates the automatic license plate recognition software with the camera's lens set to the the most narrow / zoomed in angle. The license plate detection zone is setup on the NVR between 85 and 110 feet in front of the camera. The motorized vari-focal lens of the LPR-IP4 is set to the 32mm setting. The license plate recognition software works excellent with these settings for both front a rear license plates, as you can see in the video.
Viewtron LPR Demos
Here are some additional video demos using the LPR-IP7. The LPR-IP7 uses the exact same ALPR software as the LPR-IP4. The LPR-IP7 is a 1080p / 2mp IP camera vs the LPR-IP4 which is a 4mp IP camera.
Viewtron license plate recognition cameras (LPR) are designed to detect when vehicle license plates enter a defined area. The LPR system tested in the above video used a Viewtron
LPR-IP7 license plate recognition camera connected to a
Viewtron IP camera NVR. The LPR-IP7 is the 2mp version of this camera. When a plate is detected, the event is bookmarked, a snapshot is taken, and video is recorded on the NVR's hard drive. Thumbnail images can be displayed on the live video view (like you see above) for easy access to playback the recorded video of the license plate capture.
License Plate Reader Camera + AI Vehicle Detection
Watch this video to see how CCTV Camera Pros used our the license plate reader camera in conjunction with one of our Viewtron AI cameras to detect when people are illegally dumping in our garbage dumpster. The AI camera is setup to detect people and vehicles around the dumper after hours and trigger a bookmarked event on the NVR. The LPR camera captures all license plates.
Here is a picture of our ALPR camera system setup on the pole behind our warehouse. The camera mounted down low on the pole is the LPR / APLR camera. And, the two cameras installed up high on the pole both this model
IP-A8BL bullet AI camera. We use both of those cameras as overview cameras to cover both directions of traffic around the bend. You can click on the image for a large view.
Here is a snapshot that we captured of the night time license plate recognition testing with the LPR-IP4. The license plate detection that you see above was done with the LPR-IP4's IR night vision on. We will be uploading the video tests as soon as possible. Until those are done, please check out the night time LPR video below that was captured with the LPR-IP7 (1080p version of this camera). Please click on the image for a larger view.
In this video, watch the LPR-IP7 camera capture plates at night time in a very dark environment. After watching the above video, you will better understand why it is important to install an LPR camera with at least one overview camera. This
4mp IP camera with AI is what was used as the overview camera in that video. CCTV Camera Pros sells this complete license plate recognition system that includes both cameras and the NVR.
Front License Plate Capture
Here is another night license plate capture recording. Except this one demonstrates capturing the license plate mounted in the front of the car. Also, in this video the LPR-IP7 camera is connected to a
Viewtron hybrid security camera DVR that also supports IP cameras. This is also known as a hybrid BNC DVR. Hybrid DVRs allow customers to use BNC security cameras and network IP cameras on the same recorder.
The one downside to using a Viewtron DVR vs NVR is that the DVRs do not have the ANPR software built-in. What does this mean? Basically, the camera and DVR will be able to record license plates clear enough for a human to read, but the DVR will not automatically identify the license plate and specific numbers automatically.
How-to Playback Recorded Video
Watch this video to see Mike review the various ways that recorded LPR video surveillance footage can be searched for and played back on a
Viewtron IP camera NVR.
License Plate Database
Watch this video to learn how-to create an authorized vehicle database using our Viewtron license plate reader camera and
Viewtron IP camera NVR. License plates can be added to the database via the following methods.
- Manual data entry on the NVR.
- CSV file import on NVR (comma separated value). You can download my CSV import file template here.
- Using existing license plate capture records on the NVR.
Here is a screenshot captured directly from the NVR that shows the live camera view with the real time license plate capture event thumbnails displayed on the left. You can click on these images for a full sized view.
In addition to detecting license plates, the LPR-IP4 is also an ALPR camera (automatic license plate reader). Number plate recognition and license plate database applications are possible when you connect a LPR-IP4 to a Viewtron NVR. The above ALPR database screenshot was captured from a Viewtron NVR. Please note that Viewtron BNC hybrid DVRs do not support LPR and other AI functions.You must use a
Viewtron IP camera NVR for all license plate recognition functions.
The LPR-IP4 has alarm input ports and alarm relay output ports. Installers can easily connect external alarm devices such as
magnetic door sensors / widow sensors and passive infrared motion detectors to the alarm input port of this IP camera. Ports 3 and 4 on the terminal block are the input ports.
The alarm relay output ports can be used to connect external alarm devices such as strobe lights and audio sirens. Ports 1 and 2 on the wire terminal block are the alarm relay ports. You can watch this video to learn
how-to connect an alarm light to the alarm relay output port of an IP camera.
Intelligent Video Analytics
The LPR-IP7 is has built-in software for advanced video analytics. The following Intelligent Video Analytics are supported by this camera.
- License Plate Recognition (LPR) / License Plate Capture (LPC) / Automatic Number Plate Recognition (ANPR)
- Video Tampering
- Scene Change Detection

Please use these recommended best practices in order to plan a successful
license plate capture camera installation. It is important to mount the camera so that the camera view width is 16 feet or less at the point where plates will be captured. License plate cameras can not monitor wide areas also capture small details like the numbers on a license plate. These are extremely important concepts to understand when planning a successful license plate capture system.
Watch this video to see Mike discuss all the the best practices that he recommends when it comes to installing a
Viewtron LPR camera system.
Horizontal Mounting Angle
LPR cameras should not be mounted at a distance to the left or right side of the viewing area at an angle greater than 15 degrees.
Vertical Mounting Angle
In order to capture the numbers and letters on a license plate, LPR cameras cannot be mounted at a height that creates an angle greater than 30 degrees. The less of an angle, the better when it comes to license plate capture.
Image Capture Width
It is also important to plan the cameras field of view carefully. LPR cameras are not designed to capture a wide field of view. They are designed to monitor a focal width approximately equal to a single lane of traffic (about 16 feet). Because the LPR-IP7 is 1080p HD resolution, you can go slightly wider than this in some cases (as long as the vertical and horizontal mounting angles are minimal).
The following guidelines should be used when installing this LPR camera.
- Mount between 3 and 16 feet high (not to exceed a 30-degree angle). The less of an angle - the better performance.
- Mount between 12 and 50 feet from the area where vehicles will be passing so that the area of capture is about 16 feet wide.
This LPR-IP4 can be used for stationary, slow moving, and fast moving license plate capture applications. It has been tested successfully up to 75 MPH / 120 Km/H. Please note that the higher the quality of the installation, the more realistic that higher speed license plate capture is.
