Guide to Wireless Security Cameras

Executive Summary about : Cameras Security System By Chris Pappas

The use of wireless security cameras has become increasingly popular over recent years. Some people use wireless security cameras for their ease of installation. Whatever the reason may be, wireless security cameras are quickly becoming the preferred method of surveillance for many people.

Wireless security cameras are so popular because users can literally put them anywhere added protection is needed — and the user doesn’t have to worry about wires. Wireless security cameras have a very high failure rate on initial install if precautions are not taken.

Choosing a Security System: 900MHz, 2.4GHz and 5.8GHz

The lower the frequency number, the more walls/objects your security system can pass through (except for concrete and metal).

• 900MHz wireless security cameras can be used in installs where the signal has to go through trees or dry wall in order to reach the wireless receiver. This bandwidth doesn’t have that much interference from other devices, and as a result, the signal can be relatively strong. The drawback is that right now there are only two channels available on this frequency, making its use very limited.
• 2.4GHz wireless security cameras are the most common on the market. So are 2.4GHz phones, wireless routers, keyboards, and mice that we all use. Basically, if you see something wireless on the market, there is a good chance it is on a 2.4GHz frequency. As a result, a lot of the wireless 2.4GHz security cameras fail. There are up to 12 channels available on 2.4GHz frequency that you can select for transmission, but the reality is that if you live in a city like New York or Los Angeles you won’t find a single channel that is not occupied by a wireless device.

To fix this issue, some manufacturers have started using 5.8GHz transmitters and receivers in their wireless security cameras. The 5.8GHz frequency is relatively clean, and subsequently, the successful wireless camera installation rate is higher. You can have up to eight analog wireless security cameras on 5.8GHz frequency.

But the 5.8GHz frequency has an issue. It does not go through walls as effectively as the 900MHz or 2.4GHz frequency. To resolve this issue, some security camera manufacturers have started placing high power 5.8GHz transmitters and better quality antennas in their wireless cameras. As a result of this addition, 5.8GHz wireless security cameras can now send a camera signal through a wall.

If you find a 5.8GHz camera and receiver on the market for under $200, chances are it has a 10 milliwatt transmitter in it, which is the lowest power transmitter on the market. In ideal conditions with line of sight, you can stretch it to 300 feet (in theory). The signal strength is reduced by interference and walls.

If you are looking for a camera that can transmit video up to 500 feet away, you need a camera with at least a 100mw transmitter. For a distance greater than that, let’s say 1,000 feet to 2,000 feet, you need a system with a one watt transmitter. These are very general numbers and can change based on the distance, weather, and availability of a clear line of sight.

Having an everyday zoom lens for your digital SLR camera is ideal for capturing holidays, birthdays, family get-togethers and other special moments. These versatile and easy-to-use standard zoom lenses offer crisp and clear shots for beginners or amateurs, but are also handy for the professional photographer when there is no time to change lenses. Standard zoom lenses will cover almost all situations.

Some good options include:

- EF-S 17-85mm. From wide-angle photography to standard snapshots, medium telephoto portraits and even action shots, these lenses are ideal for travelling as they offer a comprehensive range of shooting needs and are extremely lightweight.

- EF-S 18-200m. These lenses let you go back and forth from wide-angle to telephoto photography with ease. Lightweight and compact, the 18-200mm also has a high 11x zoom ratio so you can zoom right into distant action.

- EF 24-105mm. These lenses cover 24mm to 105mm, and are suitable for medium zoom portraiture as well as landscape photography. Clearly, standard zoom lenses can handle a broad range of photographic expression, from impressive wide-angle shots, to standard photography (similar to the perspective of the human eye) as well as telephoto shots.

Because of their versatility and compact size, standard zoom lenses are a must-have accessory for travellers, professional or beginner photographers as they cover most situations and offer stunning image quality.

What lenses do I need for portrait photography?

Portrait photography is all about the subject. Most portrait shots will blur or soften the background so the subject completely dominates the photograph. To achieve this effect, lenses between 50mm and 135mm lenses are often used.

Standard zoom lenses, which usually come together with a camera body, cover this focal length range, and are therefore quite suitable for portrait photography. Sometimes, however, it is necessary to use a large aperture lens with an even greater maximum aperture. In these cases 85mm lenses are the ideal option, especially if portrait photography is a serious pursuit.

Some portrait lenses to consider are:

- EF85mm f/1.2L USM. This medium telephoto lens is the standard portrait lens.

- EF 28-135mm f/3.5-5.6 IS USM. Because these lenses are a standard zoom lens, they are lightweight, extremely versatile and produce high quality images.

- EF 70-200mm f/2.8L IS USM. This is a large aperture telephoto zoom lens that covers landscape, action or sports photography, as well as portrait shots.

Single focal length lenses, like the 85mm, have a brighter maximum aperture than zoom lenses, making them ideal for portrait photography. Because the aperture is wider in these lenses, the depth of field is very shallow. This shallow depth of field softens and blurs the background, which is characteristic in portrait photography on your EOS digital SLR camera.
