2. HOW TO POSITION A LPR CAMERA<br />

Digital Security System<br />

Some steps must be followed to achieve greater results from the LPR Module.<br />

2.1 Streets, Avenues, roads and highways.<br />

Reading of vehicles in motion, without a trigger.<br />

<br />

Ideal <strong>Camera</strong> <strong>Positioning</strong> is at approximately 3.5 to 4.8 meters high. <br />

The camera mounting pole should be installed next to the curbside. <br />

Install the pole at an approximate distance of 15 to 20 meters from the point of the<br />

license plate reading for vehicles in motion. <br />

Use a 50 to 80 mm lens for a good focus of the plate area without a lot of "visual<br />

pollution" (other scenes apart from the front or rear of the vehicle). <br />

Work with a Frame Rate of 20-30 fps. <br />

Use cameras with high power shutter for vehicles in motion. <br />

Use image quality from CIF to 4CIF under MPEG-4 or H.264. <br />

For vehicles in motion, consider maximum speeds of 150 km/h. <br />

2.2 Shopping Centers, parking lots, supermarkets, condominiums and other places with<br />

tollgates.<br />

Reading of vehicles in motion, without a trigger, with speeds under 30 km/h.<br />

<br />

Ideal <strong>Camera</strong> <strong>Positioning</strong> is at approximately 1.5 to 2 meters high. <br />

Install the camera at an approximate distance of 4 to 7 meters from the point of<br />

reading. <br />

Use a 12 mm lens for good focus of the plate area without a lot of "visual pollution"<br />

(other scenes other than the front or rear of the vehicle). <br />

Work with a Frame Rate of 20-30 fps. <br />

Use cameras with high power shutter for vehicles in motion. <br />

Use image quality from CIF to 4CIF under MPEG-4 or H.264.
