Whether it is a home or an office, the biggest concern in every building is its safety and security. With the number of burglary attempts in the country rising to as high as once in every 40 seconds, effective security measures for residential or commercial premises have become a prime need for the day. The best way to get your campus secured against any kind of theft or intrusion attempts is by safeguarding it with Closed Circuit Television Cameras. These days, there are a number of CCTV packages available in the market and can be used to get a safe house or office.

People who plan on installing security cameras in their building often come across a variety of products in the market, and being not so technically sound, they have a lot of problems in deciding the right set up for the campus. Here are a few common queries that customers encounter while looking for a smart security system.

How to choose the right camera?

This is probably the most difficult question while deciding upon the right CCTV package. With seemingly endless range of cameras and lens features available these days, it is important that you choose the right camera to get complete peace of mind.

If you require great detailed images and scenes, buying high resolution cameras is a smart choice. For poorly lit areas such as garage and basements, a more sensitive camera can be used to get perfect results. Use of BLC (Back Light Compensation) can counter strong light sources and retain the picture quality, unlike the conventional cameras which produce a pale backdrop when shot against a bright background.

If you require cameras for places with concentrated light source like the car’s head lamps, prefer using a peak white inverter or an eclipser to bring details to the area and make the object clearer, which otherwise would be shadowed.

Auto Iris or Direct Drive Lens?

Direct Drive lens are appropriate for areas where a constant lighting is prevailing. These cameras do not have adjustable iris and fail to provide clear scene in case light source changes or the light level fluctuates. On the other hand, AI lens or Auto Iris lens automatically adjust the lens iris with the change in the light level. An amplifier drives the motor to open and close the iris with changes in the light.

What is ‘f’ stop number?

The ‘f’ stop number is a measuring scale of how effectively a lens allows the light to pass through it and onto the camera CCD sensor. The amount of light passed through the lens affects the quality of the image or scenes and you must select a camera which can justify the light level in campus where it has to be used.

A low minimum ‘f’ stop number means that the lens can pass through more light in the dark, producing good quality images at night. A camera with high maximum ‘f’ stop number is apt for places which have heavy light or reflection. This prevents the whiting out of images.

So next time when you set out to buying a security camera, remember these points to get the best setup for your house or office. You can even ask a reliable security service provider and get safety from any unforeseen event.
