Analog Security Cameras or IP Security Cameras? How to choose the right security cameras system.

Updated: Oct 30

Security cameras are vital to keeping homes and businesses safe.

Until recently, the installation of security video surveillance systems was most often based on analog video cameras. In such devices, the signal from the matrix (image) is supplied in analog format. This signal is digitized and processed by the camera, but for further transmission it is again converted into an analog signal and transmitted via a coaxial cable to a monitor and / or DVR.

In this device, it also goes through the process of digitization and processing, after which it is compressed for storage. In digital video surveillance cameras, the signal does not require reverse conversion, but enters the recorder unchanged.

Information from a digital IP camera can be encoded and compressed to ensure privacy and ease of storage, while the signal is transmitted over a twisted pair cable (network cable).

There are also HD-TVI cameras that do not compress or encode the signal, but use a coaxial cable for transmission. Both types of devices are capable of transmitting a signal via fiber optic cable. Both digital and analog cameras have their strengths and weaknesses.

Analog cameras are characterized by low price, simple network architecture and resistance to network failures, while they require a separate power cable.

IP video surveillance devices have the following distinctive features: camera recording is transmitted using a compressed encoded digital signal, power is supplied via a network cable (PoE technology), and a 2: 1 high-resolution image with a large number of frames per second is transmitted.

It does not require a direct connection with the registrar, it is enough to connect it online or via Wi-Fi networks, which opens up great opportunities when choosing a location for installation and allows you to increase the viewing angle of the camera. In addition, there is no limit to the number of IP devices connected to the registrar.

At the same time, the price of one IP camera is much higher than the analog one.

Due to the compression and digitization technology, the image is transmitted with a slight delay, the system may be subjected to hacker attack or virus infection.

IP devices are difficult to integrate into an existing analog CCTV system.

A feature of digital HD-TVI devices is high image quality, a simpler installation process compared to IP cameras, the ability to connect via coaxial cable and a large distance from the receiver - up to 500 m.

If properly designed and installed, the security cameras system is the best way to protect your property and to deter intruders.

Was your system designed and installed correctly?

Here are the most common mistakes that consumers make while installing their own systems:

1. Make sure to position the camera to cover as much area as possible.

2. The cameras supposed to have a clear view - if you can’t see the camera, the camera can’t see you.

3. All connections have to be waterproof as water can and will damage the exposed connections.

4. Most modern cameras have IR night vision. It is also recommended to have your own outdoor security lights to enhance the camera’s night vision.

5. Properly plan the installation process so there is no damage to the property.

6. Have the system connected to the internet router via CAT5 Ethernet cable and program the cameras system for remote viewing.

It is always the best practice to hire professionals to design and install security cameras system.

Do it right from the first time to avoid any issues in the future.
