How do I choose the right CCTV kit.

How many CCTV cameras for your CCTV kit do you need?

It’s an important question to answer since it define how many channels you need for your CCTV system. The maximum number of CCTV cameras you need determines the minimum number of channels required for your CCTV kit.

For example a 4 channel CCTV kit allows you to have a maximum of 4 CCTV cameras attached. An eight channel CCTV kit allows a maximum of 8 CCTV cameras. So think in terms of what you foresee being the maximum number of cameras you will need to monitor your dwelling. With this figure in mind you can choose the minimum channels you need for your CCTV kit. So if you needed 6 cameras for your home CCTV kit then an eight channel CCTV system will be perfect for you.

What role does the CCTV DVR play?

The CCTV DVR might be likened to the brains of the CCTV kit. It is one of the key features that determine how a CCTV system will perform.

Your CCTV cameras are connected to the CCTV DVR. The images from these security cameras are recorded onto the hard drive of the DVR. So the larger the capacity of the hard drive then the more CCTV recorded video you can store.

More often than not a CCTV system is set to a overwrite mode. This means that once the CCTV DVR hard drive is full then the oldest recorded video is overwritten with new CCTV footage. Hence it’s important that your CCTV DVR’s capacity is not too small. At the same time having a CCTV DVR with all the capacity in the world will function, but it might cost you the earth as well.

A rule of thumb that we stick to in determining the DVR capacity of the CCTV kit is this: 1TB (1000M Bytes) of hard drive storage will provide 30 days of continuous recording with 1 CCTV camera. So 4 cameras attached to a 1TB CCTV system would provide you with approximately 1 week of continuous recording, i.e. 30 days divided by the 4 cameras, before overwriting occurs.

This time before overwriting is drastically improved by having the CCTV system’s mode of recording set to movement detection. This means that video recording happens only when movement is detected by the CCTV cameras. Where we’ve implemented this recording mode at our location, the time before overwriting occurs has increased from 1 week to nearly 3 weeks.

CCTV kit Remote viewing

All our CCTV kits can be remotely accessed. This means that from your smart device you would be able to view CCTV video footage from work or across the world providing peace of mind.

What relevance is the frame rate of the CCTV System?

Imagine you’re a passenger in a moving car. You’re taking pictures of some beautiful scenery with your favourite digital camera. You’ve become a little “snap happy” and are taking pictures every one second. You can view it that you’re taking pictures at a frame rate of one per second or 1fps. If you become even more “snap happy” and held the camera button down and it took pictures every 0.2 of a second, or in other words 5 pictures per second, then it could be said you have been taking pictures at a frame rate of 5fps (5 frames per second). However you’ll run out of camera storage more quickly than if you were taking pictures at 1 picture per second.

A CCTV camera system operates in a similar manner taking continuous pictures, or frames, at a set rate and storing these digital pictures on the CCTV system’s hard drive. A frame rate of 10fps indicates the CCTV system is taking pictures or frames at 10 per second. A frame rate of 20fps (20 frames per second) amounts to 20 images stored on the hard drive every second. The higher the frame rate the less jerky video replay will. However you’ll use the CCTV DVR’S storage capacity more quickly as well.

With our CCTV kits attached to a 4MP HD camera you can expect a frame rate of 8fps. A CCTV camera system with a 2MP HD CCTV camera attached, a frame rate of 12fps will be achieved. However in both case you can still use the rule of thumb mentioned earlier of: 1TB (1000M Bytes) will provide 30 days of recording with 1 camera. The difference will be that a 4MP HD camera will store a more detailed images than a 2MP (1080P) CCTV camera.

Conclusion

Choosing a CCTV kit has been made simple with our range of CCTV systems. You need to ask yourself 3 questions before making a purchase.

  1. How many cameras do you need in total? This determines how many channels your CCTV system needs
  2. Do you want this CCTV system to be wired or wireless?
  3. What capacity CCTV DVR do you require?
  4. Will a 1080P (2MP) CCTV camera suffice or do I need a more detailed (4MP)

Having answered all these questions you are ready to purchase a CCTV kit from us that will provide many years of service.
