What is CCTV IP Camera

IP camera is a type of digital video camera used for surveillance which transmits data via a network Ethernet link also known as Internet Protocol camera.

An Internet Protocol camera, or IP camera, is a type of digital video camera that receives control data and sends image data via an IP network. They are commonly used for surveillance but unlike analog closed-circuit television (CCTV) cameras, they require no local recording device, only a local area network. Most IP cameras are webcams.

Benefits of using IP Cameras Over CCTV Cameras

• Two-way audio: A camera owner can listen and speak to a subject via a speaker on the camera. Some doorbell cameras offer this function.
• Remote access: Authorized users can view live video footage from any smartphone, tablet, or computer.
• Better resolution: IP cameras have up to 4x the resolution of analog cameras.
• Fewer cables and wires: Power over Ethernet supplies power through the Ethernet cable, allowing the camera to operate without a dedicated power supply.
• Cloud and Built-In Storage: Storage space is a huge consideration when surveying IP cameras. By law, many companies are required to retain security footage for a specific amount of time depending on their industry and local mandates. Most surveillance systems will transmit video data onto cloud storage, a Solid-State Drive (SSD), or a Hard Disk Drive (HDD). Advanced solutions store footage locally on an SSD or HDD while also backing it up in the cloud; these “hybrid cloud” security systems are considered safer and more reliable than systems that rely on just one method.
• PoE Capabilities: IP cameras that can be powered over a PoE connection eliminate the risk and cost of running electrical wire. Compared to purely wireless cameras, PoE IP cameras tend to have more stable data transmission and less likely to encounter interference from nearby devices.

Where Use IP Camera

IP cameras are commonly used in;

• Bank
• Retail Stores
• Business Offices
• Government Buildings
• Industrial Sites
• Military Facilities
• Traffic Intersections

Types of IP Cameras

• PTZ IP Camera: Pan-tilt-zoom (PTZ) cameras can adjust their field of view and angle via a remote operator, allowing users to track events with greater control. They can cover potentially large areas and are commonly used to monitor public outdoor space.
• Fixed IP Camera: Fixed IP cameras operate in a static position and provide a single view within the camera’s field of vision, continuously surveilling subjects within a predetermined frame. Fixed cameras are widely used both outdoors and indoors, typically in retail stores and business offices. Compared to PTZ cameras, they require less bandwidth to support.
• PoE or PoE+ IP Camera: PoE IP cameras use an Ethernet cable (usually Cat 5 or 6) to supply both electrical power and data simultaneously. This eliminates the need to run two cables for power and data separately, thus reducing the amount of hardware required. With fewer parts to deal with, PoE systems tend to be easier to install and cost less to maintain compared to traditional systems. The difference between PoE and PoE+ is the amount of electricity each one transmits to power their systems. Standard PoE systems power most IP cameras and transmit up to 15 watts of electricity. PoE+ systems transmit up to 30 watts and are usually used in more high-power cameras with their own heating and cooling mechanisms.
• Wireless IP Camera: Wireless IP cameras connect to a WiFi router to send video data. The footage is then transferred to cloud storage or the camera’s local built-in storage. Wireless IP cameras can be a good solution for small homes, but a wired camera system is less susceptible to interference and recommended for larger areas.

Difference between IP Camera and CCTV Camera

IP CAMERA	CCTV CAMERA
IP Camera also known as Internet Protocol camera.	CCTV Camera also known as Close Circuit Television.
IP camera is a type of digital video camera used for surveillance which transmits data via a network Ethernet link.	CCTV Camera is a type of digital video camera used for surveillance which transmits a signal for observation on monitor.
IP camera broadcasts video as a digital stream of data over an IP network to a Network Video Recorder (NVR) rather than a DVR.	CCTV camera broadcasts the video to a Digital Video Recorder through coaxial cables.
IP cameras use Power over Ethernet(POE) so that the need of power cables are eliminated.	CCTV cameras use coaxial cables and UTP cables as power and network cables.
IP cameras offer higher resolution video and better picture quality than CCTV cameras.	CCTV cameras offer lower resolution video and less picture quality than IP cameras.
In this system multiple number of IP cameras can be added.	In this system limited number of CCTV cameras can be added.
Creating an IP camera security system needs less cost than creating and maintaining CCTV camera security system.	Creating a CCTV camera security system needs more cost than creating and maintaining IP camera security system.
IP cameras use Wi-Fi, LAN or cellular network for connectivity.	While it uses a television to broadcasts signals.

What to Consider When Buying an IP Camera

• What’s the scope of the area being surveilled? (Distance? Scope?)
• How much internet bandwidth is needed to support the camera?
• How will footage be stored, and how much space will you need?
• Is data encryption up to modern security standards? (RSA vs. AES? At rest vs. in transit?)
• Where is it being placed? (Indoor? Outdoor?)
• Does it utilize encrypted transmission? (SSL/TLS?)
