IP Cameras

What is an IP camera?

An IP camera, also known as an Internet Protocol camera, is a type of digital video camera that transmits and receives data via a computer network and the Internet. Unlike traditional analog cameras, IP cameras convert video footage into a digital format, which can then be easily stored, transmitted, and viewed remotely. This makes them highly versatile for organisational and business security systems. IP cameras offer high-resolution images and can be accessed from anywhere with an internet connection, providing real-time monitoring and recording capabilities.

What differences are there between IP and analog cameras?

IP and analog cameras differ primarily in how they transmit video data. Analog cameras convert images into a format that can be transmitted over coaxial cables, whereas IP cameras convert images into digital data that can then be sent over a network. IP cameras offer several advantages over analog cameras, including:

• Remote access and control via the internet
• Easier integration with other digital systems
• Plenty of scalability and flexibility in system design
• Network or cloud storage of footage can be very convenient.

Analog cameras do have the advantage of being generally less expensive and easier to install, making them a suitable choice where security needs might be simpler and more straightforward.

How much data/bandwidth does an IP camera use?

The amount of data and bandwidth an IP camera uses depends on various considerations, including the resolution, frame rate, and compression settings. The most important factor in how much data will be used is the resolution and the framerate, so if your data and bandwidth are limited it may be possible to simply lower the image quality. Additionally, using motion detection can help reduce data usage by only using recording capacity when movement is detected.

Are IP cameras secure?

IP cameras can be secure if properly configured and maintained. It should be borne in mind however that like any device connected to the internet, they can be vulnerable to hacking if not protected. To enhance security, you may want to consider taking the following steps:

• Use strong, unique passwords for each camera. Where possible, try and use longer passwords or passphrases with a mixture of upper and lowercase numbers, letters and symbols to make the token unguessable.
• Enable encryption for data transmission if it is not enabled by default.
• Keep the camera's firmware up to date. Some cameras will update their own firmware automatically but others will not, so ensure that you check the manufacturer’s instructions and schedule firmware checks and updates manually if necessary.
• Use a secure network with a firewall.
• Consider using a VPN for instances where remote access is required.

Will IP cameras slow down the network they are installed on?

IP cameras can potentially slow down your network, especially if you have multiple cameras streaming high-definition video simultaneously. The impact that the IP cameras will have depends on both your network's bandwidth, and the cameras' resolution and frame rate. To mitigate this, consider using a dedicated network for your cameras or adjusting the camera settings to reduce bandwidth usage.

Should IP cameras be on a separate network?

Placing IP cameras on a separate network is generally considered good practice for several reasons. It enhances security by isolating the camera network from your main network, reducing the risk of hacking or unauthorised access. Additionally and as mentioned above, a separate network can help manage bandwidth more effectively, preventing cameras from slowing down your primary network. Having a dedicated camera network setup also simplifies network management and troubleshooting.

Do I need an NVR for IP cameras?

An NVR (Network Video Recorder) is not strictly necessary for IP cameras, but it can greatly enhance their functionality. An NVR provides a centralised location for storing and managing video footage, often with additional features like motion detection and remote access. Alternatively, you can use a computer with surveillance software or cloud storage solutions, but an NVR will usually offer a more streamlined and dedicated approach.

How do I find the IP of an IP camera?

Finding the IP address of an IP camera can be done in several ways. First, check the camera's manual or the manufacturer's website for default IP addresses. Another easy method involves checking online, because if the camera has a web interface, you can often find the IP address there as well. If those methods don’t work, you still have several options-once the camera is connected to your network, you can use network scanning tools to locate it. Additionally, many routers have a list of connected devices in their admin panel, which can help you identify the camera's IP address.
