CAMERA TYPE

There are a variety of camera models available and with all the different features they have to offer it can be hard to decide which type best suits your requirements.

GENERAL OR BOX CCTV CAMERAS

These cameras tend to be insight but out of reach. People will know they are there yet they won’t know exactly how far the camera can see or what angles, a good choice for deterring thieves. They are usually feature-rich and a more affordable choice. These cameras are best installed on high ceilings, tall exterior walls and places out of reach, as they can be easily tampered with if reached.

RESOLUTION

Resolution is an important factor to consider. Higher resolution captures more detail. How detailed do you need your footage to be? If simply recording motion a lower spec and more affordable camera will suffice, however if recording to protect valuable items you will benefit from higher resolution, as in the event of theft or crime you will be able to identify details such as faces and number plates.

It is important to remember when choosing your camera resolution it must match up with your DVR or NVR’s recording resolution. High resolution cameras are not compatible with low resolution DVR and NVR’s.

WHAT IS A DVR AND NVR?

Both are video recording devices which run 24 hours a day recording all the footage your cameras capture.

Digital video recorder (DVR)

Digital video recorders are used with analogue CCTV. The cameras are wired in to the digital video recording device.

Network video recorder (NVR)

Network video recorders are used with IP CCTV. The cameras send footage via your home network and do not need to be wired into the network video recording device. However the cameras and NVR do need to be connected to your home router.

DO I NEED A DVR/NVR?

Some people think a PC can be used over DVR or NVR, we would not recommend this. A video recording device records footage 24 hours a day, 365 days a year, sending footage to the hard drive. A computer is designed to run intermittently with relatively long rest periods, what if you missed an important section of footage?

In the case of a break in often a computer is a prime target, and you would instantly lose your recordings if the computer was stolen, where as a video recording device can be set up in a secure or discreet location.

The video recording device is specially designed to handle the large processing power video data takes up, where as a computer may experience performance issues. Software and capture card equipment required for CCTV on a computer can also be very costly.

DVR/NVR BENEFITS

Continuous Recording
Continuous Recording

The recording device continuously records and when the hard drive is full it will go back to the beginning and record over the earliest footage.

Motion Sensing
Motion Sensing

For more efficient recording motion sensor recording can be set up, recording only when the cameras senses movement.

Scheduled Recording
Scheduled Recording

You can specify what type of recording takes place at various times throughout the day and on particular days of the week.

Accessible
Accessible

Recordings are stored on a hard drive, making them easily accessible. Transferring footage via USB can be easily achieved to share or backup recordings.

WHAT SIZE HARD DRIVE DO I NEED?

Storage requirements vary per customer, there are a few factors you need to consider before selecting your hard drive size.

How many days footage do you need?

When the hard drive is full recordings will begin to overwrite the earliest footage.

How many cameras are you setting up?

The more cameras you set up the less recording time capacity you will have.

What quality footage do you need?

The higher the quality reduces the hard drives recording time.

Some of our CCTV kits have pre-installed hard drives to make it easier for you, others have the option for you to choose your hard drive size to suit your needs. Many recording devices also have the capability of expanding storage space if you find you require more.

As each CCTV kit is different for each customer’s requirements it is hard to generalise how long a hard drive size can record for. Here are some examples to give you an overview of hard drive capabilities when recording is set to motion detection.

Analogue CCTV with 2 cameras & a DVR with 500GB hard drive – allows for 30 days worth of footage.

IP CCTV with 4 cameras & an NVR with 1TB hard drive – allows for 48 days worth of footage.

IP CCTV with 8 cameras & an NVR with 2TB hard drive – allows for 48 days worth of footage.

THINGS TO CONSIDER

 
Resolution Recording

RECORDING RESOLUTION

DVR and NVR’s have different recording resolutions. It’s important you select cameras and recording devices that are compatible. There’s no point in producing high quality footage with high resolution cameras if the recording device records at a low quality.

STANDARD RESOLUTIONS

Standard Resolutions

HIGH RESOLUTIONS

High Definition
TVL

TVL

320, 400, 420 TVL - Give little detail, ideal for monitoring motion

480, 540, 600 TVL – Offer better clarity for short to medium distances only

650, 700, 800 TVL – Deliver higher quality images for longer distances

Real Time Recording

REAL TIME RECORDING

Setting the recording device to record in real time increase the captured frames per second, this can decrease your recording time capability. We recommend 3-6 frames per second, real time recording averages as 24 frames per second.

Example – IP CCTV with 4 1080P cameras and a DVR with a 1TB hard drive recording at 6 frames per second can cover 12 days of footage whereas setting it to record at real time will cut the footage down to 3 days.

Channels

CHANNELS

CCTV kits have different channel capabilities. The number of channels specifies the number of cameras that can be set up and record simultaneously with your DVR or NVR.

Example – 4 channels allows you to set up 4 cameras around your property.

Wireless

WIRELESS

The term wireless with CCTV can be misleading. Cameras that are classified as wireless are not connected to a DVR or NVR, however they still require connection to a power source.

Your Situation

YOUR SITUATION

It all depends on what your situation is as to what kit will be right for you. For example, If you already have network cabling installed, an IP CCTV kit would be the easiest system for you to fit.
