When considering a CCTV system, selecting the right cameras, recorder, cables, price that fits the budget and understanding terminology is more important than ever before. Ask the supplier to help you select the right system to suit your budget. Having a budget is important but consider your options before you make that final choice. High definition cameras are very reasonably priced. Do you need night vision capability, if so what range does it need to cover?
Consider the area each camera needs to cover and then select the most suitable lens! Remember unlike human eyes, camera lenses do not auto adjust;. For night vision, consider the area infrared needs to illuminate at the night. Cameras may look the same but the image sensor can make all the difference. A branded image sensor will produce higher quality pictures with true colours and clearer picture for both day and night.
Do not be mislead by some manufacturers; any doubt talk to the supplier before making a purchase. Storage capacity of DVR; how many days of recording it can hold before it auto overwrites? Consider your longest holiday period to make sure there is footage for the entire period.
How will you record; continuous or on motion? If motion, does the recorder support motion mask? Motion mask can help increase storage time. Do you need "privacy masking" for privacy of others? Not all recorders have a "privacy mask" feature. Do you need computer, mobile phone and tablet access?
Most recorders have computer and smart phone access, but level of access and features vary. A connection from recorder to broadband will be required. Other features to consider, number of camera inputs, smart search, supported technologies future proof.
Pre-made leads - these leads have video and power connectors already on the cable. Indoor CCTV cameras come in three types: wired, wireless, and powerline networked - these plug into your electrical sockets and transmit images to a storage device. Typically, if you want an indoor security camera it's best to choose a wireless model. Browse our list of the best wireless cameras for some recommendations.
CCTV camera resolution is measured in lines - the higher this is, the sharper the image will be. Image quality is also linked to the size and type of chip the camera uses. Cameras with tiny chips also tend to be able to pick up less light, and therefore produce lower-quality images in low light.
The light sensitively is measured in lux, which can range from , to 0. The lower the lux, the better the camera will be at recording when there isn't a lot of light. You'll need high-quality images - sufficiently clear for someone to be identified - if CCTV footage is to be used as evidence in court. For the best detail, you need a high resolution - this tends to make the camera more expensive, and can take up a lot of storage space. Test score. Should you invest in CCTV?

This is where security cameras come in. We read news stories and even watch on TV how security cameras have been used often to identify and even arrest crime suspects. CCTV cameras can be used either for domestic or industrial purposes. Before buying that CCTV camera, there are some things that you have to keep in mind.
The following are some pointers to keep in mind when buying CCTV cameras:. The CCTV camera lens if what gathers the light from the sensor. Everything that the viewer sees or everything that is recorded on the DVR comes in through the lens. The lens is what controls the focus because it is what determines whether the images recorded can be recognized.
Therefore, if the lens is not in focus, then there is no point of surveillance. There is need to understand that not all digital sensors are created equal. When choosing a sensor, there are two main sensor specifications of a CCTV camera that you can look for; that is the type and size of the sensor.
The size of the sensor also matters. The larger the sensor is the more light it can process and the higher the quality image it can produce.
