5 Reasons to Choose High-Resolution GigE Vision Cameras

At higher image resolution, GigE Vision Cameras with a digital zoom can be made to a frame or video without having a considerable loss of quality. For example, if you zoom in on a fullHD image, you’ll be lucky if you see anything in detail. However, you will have excellent quality if you do it from a GigE Camera.

1. Comparison of sizes and image resolution

One detail to remember is that the higher the resolution of the GigE Camera, the more space the recordings take up, whether on a recorder or an SD card. Therefore, it is crucial to assess the recording quality, the amount of time, memory capacity, etc. Below you have details about this.

• Vision angle

Similarly, you have to pay attention to something significant: the viewing angle of GigE Vision Cameras. What is the field of vision? Therefore, the entire area to which the camera lens has access will reflect in the image. This is extremely important. We will be interested in a wide or narrower viewing angle, depending on what we want to record.

Examples:

GigE Vision Cameras in a factory corridor, which measures 2 meters wide and 20 long. In this case, it is not interesting to have a wide-angle camera since we would see more of the wall on the sides than the corridor. It is more interesting to have a camera with a narrower angle, for example, 45 degrees.

• Expressed in millimeters

Typically GigE Vision Cameras manufacturers help us choose by giving the degrees of opening in their description. But, most professional equipment will leave a number written that corresponds to the depth of field and the degree of an aperture of the lens. This feature is expressed in millimeters; the shorter the distance, the greater the field of view. The lowest is probably 1.4mm, which corresponds to 180. 1.8 mm is 140, 2.8mm is 108, and 3.6mm is 90.

GigE Vision Cameras on the ceiling provide a full 360 view or a panoramic view.

Store the video on a VCR

It is a good option if you have chosen an analog or IP camera connected to a DVR. Storing video on a device like this has several advantages:

• It allows you to record more time, but keep in mind the maximum of 30 days.
• You can access recordings remotely and locally and download them to a flash drive without hassle.
• Access for viewing images remotely carries a compression process that allows less bandwidth to be used both for uploading and downloading.

The calculation can be made as follows: 1Tb of hard drive for 4 cameras at 2MP gives storage for approximately 20 days. It can vary a lot, depending on the recorder’s video compression and the movement the surveillance cameras receive. So it is always better to go on top to avoid getting your fingers caught.

However, almost all modern recorders allow you to install two HDDs inside, so if you want to make an expansion, you can.

• Record IP camera video to SD card

If you opt for this option, you must consider several factors: the size of the microSD memory and the amount of recording time. Many GigE Vision Cameras have a maximum supported memory depending on camera location, quality, etc. We may reach the limit of that capacity in a relatively short time. Therefore, the best thing to do is to configure it so you can save as much memory as possible.

• Recordings of images in the Cloud

Following the constant increase in the quality of GigE Camera, the demand for cloud storage has increased. The operation is the same as if you try to access a video recorder remotely but without having it physically. If you have to put a downside, it would be the cost of this service, since it is paid. But in return, you completely forget about maintenance, security, and storage.
