How to Pick the Right Camera Lens

When building a surveillance system for your home or business a little planning can go a long way in making sure you find the right security camera and CCTV lens combo. By heeding a few of these tips and gaining some knowledge; you will make it that much easier to find the perfect CCTV lens.

Lens Selection Often Drives Camera Selection

The type of CCTV lens you choose to use with your security camera can often drive the type of camera you will use as well. The reason for this is due to the fact that different style security cameras support different format lenses.

If you already have a security camera make sure you know what type of lenses it supports. For example a mini camera is unlikely to support a zoom or motorized type lens; whereas a C/CS mount type security camera would. The C/CS mount camera however would not support M12, M9, or other types of mini CCTV lenses.

CCTV Lens Focal Length

To determine what focal length you are going to need you can use a lens calculator. You will first need to assume a fixed width of view at a particular distance, and then plug this information into the lens calculator to determine what focal length is best suited for your application. Usually a quick google search can help you find a lens calculator for the different format CCTV lenses out there such as 1/3″, 2/3″, 1/4″, etc…

Now something you should keep in mind is that after you determine your focal length you need to decide on whether you want a fixed focal length or a varifocal type CCTV lens. The answer to this hinges on if you plan on changing the view at all. If you want to be able to change the view; then you should find a varifocal type lens containing your needed length in its range. If you don’t need to change the view of your camera at all; then it would be wise to just stick with a fixed focal length.

Knowing The C/CS Mount Lens Difference

When it comes to box style security cameras, they are categorized into 2 mounting types; C or CS mount. Most of the modern cameras you see today use the CS mount format because it allows for the use of both C and CS CCTV lenses.

To be able to use a C mount lens on a CS mount security camera you will have to be sure you have the proper 5mm adapter ring to allow the lens to get the proper distance from the imager. Be warned however that if this ring is present when you have your CS mount lens mounted it will not allow for a proper focus, and it could potentially damage your CCD imager.

On the other hand a CS mount CCTV lens cannot be used with a C mount security camera, as it will not be able to get close enough to the imager to achieve a proper focus.

Optical Zoom vs Digital Zoom

This topic is somewhat more related to the zoom CCTV lenses and the capabilities found on the camera, but it is something good to know when dealing with a zoom capable security camera and lens.

Optical zoom is generally the better of the two and it’s your camera/lenses ability to bring the image in front of you closer without loss of resolution.

Digital Zoom is your camera simply enlarging a portion of the image you see and showing it to you. This technique results in a loss of image quality.

Ultra Compact Digital Camera Wish List

When you are looking for the ultra compact digital camera, you will first look for a camera that is compact, which would be the Canon PowerShot SD870 IS. The camera has perfect image quality and is easy to use. Thos camera comes with 8.3 megapixels and image stabilization. The camera does have wide-angle capabilities with auto focus and face detection. The small camera is great for traveling because it fits nicely in a pocket or fanny pack.

The best value for an ultra compact digital camera would be the Canon PowerShot SD1000. The only disadvantage with this camera is that it does not have image stabilization. If you think you are a steady shooter, this camera will be ideal. The camera has 7.1 megapixels with color sharpness. The compact camera is only three quarters of an inch thick. The camera does have many different scene modes and a few manual controls.

The stylish ultra compact digital camera would be the Fujifilm Z10fd. This particular camera is stylish and the younger generation finds this a hot and must have camera. The blog mode allows you to resize the images right in the camera for posting on your blog or sending in an email. The camera is great for the price and functions that it has.

The best ultra compact digital camera for low light images is the Fujifilm F40fd. This camera has everything you need to take perfect images in any low light settings. The camera is stylish and compact making it very hard to resist. The images you capture in a lighted setting are clear and crisp appearing almost lifelike. When looking for the best ultra digital camera, you will want to compare these cameras and see which one would suit your needs for lighting and price as well as ease of use.

Rechargeable Batteries – Best Digital Camera Batteries

I’m not going to insult you by teaching you how to put a battery into a camera. That’s something pretty much anyone can do without help. As long as you follow the diagram and put the batteries like it shows there, you’ll be OK. What I am going to teach you here is how to boost the battery life, since taking photos can be taxing even on the best digital camera batteries.

Use rechargeable batteries to save money

When a camera takes AA batteries, there is a good chance it will accept rechargeable batteries as well. You will have to pay more for batteries that are rechargeable, but in time you will save money. If you use regular AA batteries, in a month you can easily go through a megapack of them.

Here are some facts about batteries that are rechargeable:

There are two main types of rechargeable batteries: NiMH (nickel-metal hydride) and NiCad (nickel cadmium). If you want the best possible performance from your batteries, you should go with the NiMH. Still, if you already have NiCad lying around in the house, you can use those as well.

If you want to use it while you’re away doing business or in a vacation, you might want to consider a charger for small format batteries . The price of such a charger is around $30 and it comes with a four battery pack to get you started.

Depending on the charger, some batteries will be charged quicker than others. The package of the charger should indicate how fast it works. But, if you want a battery to recharge faster, you will probably pay more for it.

You should buy a second set of rechargeable batteries. Even if one of them is in the charger, the other one can be used.

Even though a rechargeable battery is fully charged, if you leave it for a few weeks it will lose some of its power. In time they will discharge completely.

Even if you plan everything well, eventually you will be in a situation where your battery is dead.

Battery power preservation

The current technology makes sure that cameras deplete batteries slower than before. Still, a digital camera will consume more power than a film camera, because they have a lot of extra features.

All digital cameras show a battery icon on their screen, which tells you that everything is OK when it’s full and that you will run out of battery juice when they’re almost empty.
