What is a dome camera

A dome camera is named for its shape, which is a hemisphere. Due to its small size and beautiful appearance, the dome camera is suitable for indoor places, cars and places with high-grade decoration. Its interior is a dome camera composed of a camera, an automatic iris manual zoom lens, a dome cover with excellent sealing performance and a precise camera mounting bracket. Its biggest feature is its compact design, beautiful appearance and easy installation.

The image generation of the dome camera is mainly from the CCD dome camera chip. CCD is the abbreviation of charge coupled device. It can convert light into electric charge, store and transfer the electric charge. It can also take out the stored electric charge to change the voltage, so it is ideal. The CCD camera chip is widely used because of its small size, light weight, not affected by magnetic fields, and anti-vibration and impact.

One of the main differences between a dome camera and a normal one is the type of lens used. A dome camera has a lens with variable focal length, which allows the user to adjust the monitoring distance. Most dome cameras are capable of monitoring up to 100 feet away. The lens on an exquisite camera can rotate 180 degrees and can rotate both horizontally and vertically.

Some dome cameras rotate 360 degrees and are equipped with a fisheye lens that provides an incredibly wide surveillance field. Most dome cameras are ceiling mounted, but there are also some models that rotate around 360 degrees.

How does dome camera work

The working principle of the dome camera is roughly as follows: the optical image generated by the object through the lens is projected onto the surface of the image sensor, and then converted into an electrical signal, which is converted into a digital image signal after analog-to-digital conversion, and then sent to the image sensor. It is processed in the digital signal processing chip , and then transmitted to the computer for processing through the USB interface, and the image can be seen through the display.

Why install dome camera inside the vehicles

Why install a dome camera? Because it can effectively improve driving safety. When the dome camera is installed on the console as a dash camera of the bus, it can take real-time pictures of the road traffic information. When an accident occurs, evidence can be provided to divide responsibility. When installed above the driver’s position, it can monitor the driving area and the information of passengers getting on the bus.

When the dome camera is installed in the front of the bus, it can take a panoramic view of the bus. If there are special circumstances in the bus, the background system personnel can keep track of the situation in the bus at any time.

When installed in the middle position above the exit door, it can monitor the information of the passengers getting off the bus, and transmit the information to the monitor to make the driver to open and close the door.

When installed on the top of the rear of the bus, during driving or reversing, the signal of the camera will clearly display the monitoring situation around the rear of the bus on the reversing monitor, and the driver can easily grasp the situation at the rear of the bus at any time.

Advantages of dome camera

One of the main advantages of dome cameras is their versatility. They come with a variety of features, including HD and SD video recording and IR vision of up to 20 meters.

Another advantage is that they have a compact design that allows them to fit in tight spaces. This makes them convenient for a variety of security and surveillance needs. You can easily install these cameras yourself.

What’s more, most dome cameras have waterproof housings and are resistant to rust and corrosion. Others feature bullet-proof glass coverings and steel cages that protect the camera’s dome fixture.

A dome camera’s image quality varies depending on its features and price. A more expensive camera will most likely have a clearer image. Consider the camera’s zoom capabilities when evaluating your options.

How to install dome camera

There are a few steps to installing a dome camera, and they can all be done by one person.

1. Research product performance

After getting the dome camera, the engineer and the user should be familiar with the technical parameters of the product, such as the input voltage and the power. These are the first things that users need to figure out when installing the camera. After understanding these parameters, the following installation can be carried out smoothly step.

2. Check the function

Before installation, the dome camera should be inspected and adjusted. Once there is a problem, it should be adjusted in time to ensure that the camera is in normal working condition before the official installation can begin.

3. Installation method

Before construction, installation can be carried out according to the environment and the monitoring needs of users.

4. Installation angle

The different installation angles will directly lead to the transformation of the camera range. Therefore, in the actual installation, it is necessary to carefully select and adjust the installation angle, and at the same time, avoid the situation that the camera is in the backlit shooting situation.

How much does a dome camera cost

If you’re deciding between dome and box cameras for your security needs, you’ll need to decide which features you really need. While box cameras can be a cheaper alternative, they are less discreet than dome cameras. Box cameras often have more advanced features such as noise reduction and auto white balance. They can also be installed over cable connections. If you need a camera that can monitor a larger area, you may want to choose a dome camera.

A basic dome camera security system costs between $150 and $1,200 for end users, but if you need more than one camera, you can hire a security professional for installation. Prices vary by region and number of cameras. Generally, an 8-camera system will cost about $500.

How to find reliable dome camera manufacturer

Different industries have different requirements for suppliers. How to choose a suitable supplier for the automotive electronics industry? Knowing the following points can help you.

1. Qualification of suppliers

Any supplier should have a clear legal status, and some specific commodities should have corresponding production and operation licenses or certifications. For example, suppliers producing explosion-proof cameras must obtain product explosion-proof certification.

2. Management and technical level

The management level of suppliers is directly related to the quality and ability to provide products and services for enterprises. For example, whether the management level has passed the IS09000 quality system certification, and whether its quality level meets the requirements specified by the internationally recognized IS09000. Whether the technical level of the supplier meets the requirements. Enterprises should choose suppliers with complete qualifications, high management level and technical level that can meet the requirements.
