Here are some frequently asked questions that we receive about LPR cameras.
What is an LPR camera?
An LPR camera is a specialized type of video surveillance camera that is designed to capture the numbers and letters of license plates on moving vehicles.
Which is better? The IP LPR camera or the CCTV LPR camera?
The Viewtron IP camera LPR system (LPR-IP7) is the best choice by far. It is best because it uses AI software to automatically detect the license plates and numbers and letter on them using ANPR (automatic number plate recognition). We recommend the LPR-AHD5 CCTV LPR camera to customers that already have coax cable in place and do not want to re-wire their system for IP cameras. The LPR-AHD5 does do an excellent job of capturing license plates in clear video. There is just no automatic plate of number recognition.
Why are overview cameras recommended with LPR cameras?
Most LPR cameras are tuned to capture ultra high contrast video in black and white. This is great for capturing license plates but not very good for capturing an overview the the vehicle. Also, LPR cameras are typically focused on a small area (about the width of a single lane of traffic), so that the plate is clearly in focus. It is nice to have a color overview of vehicles and a clear capture of their plate.
The above surveillance image was captured using a license plate capture camera. As you can see the camera is configured to capture the license plate effectively, but does not provide any overview of the vehicle. This is the same type of result that you can also expect from our
HD CCTV LPR camera that runs over coax cable.
What type of DVR is used with CCTV LPR cameras?
CCTV Camera Pros recommend using a DVR or NVR that is capable of recording at least 30 FPS (frames per second) at the resolution of your LPR camera. For example, this
LPR-AHD5 camera is capable of 1080p / 2 Megapixel HD resolution. We highly recommend the Viewtron surveillance DVRs that we supply for use our BNC / Coax cable LPR camera. Because the LPR-AHD5 is compatible with AHD, HD-TVI, HDCVI, and analog CCTV (CVBS) video formats, it is compatible with CCTV DVRs from all major manufacturers including Swann, Samsung, Night Owl, Lorex, QSee, Defender, Digital Watch Dog, and just about all others. If you need help determining compatibility with your DVR, please email CCTV Camera Pros here.
How can I monitor the gated entrance of our HOA?
Monitoring a traffic gate at a residential HOA community typically requires an LPR camera and an overview camera for each lane of traffic that you want to monitor. Many HOAs use a license plate camera for both incoming and outgoing traffic. Please take a look at these
LPR systems for gated entrance HOAs.
What is ANPR software?
ANPR software stands for automatic number plate recognition software. ANPR software is OPTIONAL to use with LPR cameras. ANPR software uses optical character recognition to identify the numbers and letters on license plate, then takes some sort of action such as logging the plate to a database or automatically opening a security gate. Viewtron IP camera NVRs have built-in ANPR software. Please take a look at this
Viewtron ANPR camera system that includes a Viewtron NVR, VIewtron LPR camera, and one overview camera.
Please watch the below video demos to learn about our best selling Viewtron license plate reader system.
LPR ANPR Camera System
Watch this video to see the Viewtron IP-LPR7 LPR camera used with (2)
Viewtron AI security cameras to provide a complete LPR / ANPR camera system. Check out this video to see the different ways to search & playback recorded LPR video footage.
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-IP7 license plate reader camera captures 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-A4BZ 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.
LPR System Demo
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 AI camera connected to a
Viewtron IP camera NVR. 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.
Watch the Viewtron license plate recognition system 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.
In addition to detecting license plates, the LPR-IP7 is also an ANPR camera (automatic number plate recognition). Number plate recognition and license plate database applications are possible when you connect a LPR-IP7 to a Viewtron NVR. The above ANPR 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 AI functions.
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. This video shows how well the LPR-IP7 compensates for headlight glare. 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. Only Viewtron NVRs have the automatic number plate software built-in.
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.
Watch this video to see Mike review the various ways that recorded LPR video surveillance footage can be searched for and played back on Viewtron NVRs.
LPC vs LPR vs ANPR Explained
Watch this video to hear Mike explain the differences between LPC (license plate capture) vs LPR (license plate recognition) cameras. Mike also discusses ANPR (automatic number plate recognition) software.
CCTV Camera Pros supplies this
wireless camera system as an add-on for IP cameras. Watch the above video to see the LPR system installed at CCTV Camera Pros warehouse in West Palm Beach, Florida. We are using the WIFI system to transmit HD video from 3 security cameras mounted on a pole behind our building. This system is working great. This was an important demonstration because license plate recognition requires high quality video and frame rate. The fact that we are able to do this over WIFI is important to document for our customers. Please note, we ALWAYS recommend hard wiring camera systems. Wireless is ONLY recommended as a last resort if hard wiring is not possible. Wireless is NOT as reliable as a hard wired surveillance system.
Watch the above video to compare the video captured by a license plate recognition camera versus a traditional security camera (non LPR) in a moving vehicle traffic application.
License Plate Capture
CCTV Camera Pros license plate recognition (LPR) system, provides high-resolution video monitoring and recording. Our License Plate Recognition (LPR) system is an effective video
surveillance and parking lot monitoring solution. Many parking lots have a high security risk rating. It is difficult for security personnel
to monitor isolated areas or levels of large lots. Most lots need an effective digital surveillance system to provide live monitoring
and continuous recording. These video surveillance
systems provides protection and reassurance to customers and
employees.
The license plate capture system activates the LPR recognition
process in two ways. The first is via software video motion detection,
which detects vehicles passing through the camera and illumination zone.
The second is by input / output activation, which triggers recognition and
recording upon I/O activation. The system supports both camera overview
and picture-in-picture modes with ease of monitoring.
