There are several types of home video security system. There are wired video surveillance systems, wireless, VCR system and IP-based systems. Wired systems can be connected to other security devices like VCR.
Wireless systems need televisions or computers to detect and start recording. The IP-based or web-based systems require the use of internet for recording and streaming. Whatever video security system you may choose for your home, you may need similar equipment.

For your security surveillance to start working, you may need surveillance cameras, recording or playback device, monitor and motion detector. Of course, cameras are for recording events and activities, the images captured are sent to the playback device for recording, and the monitor provides images to you or to the one in charge with the home video security.
High-end security cameras are equipped with infrared sensors to enable the system to see at night. However, their price is also high-end. If you prefer to use non-sensor cameras, you may need to install outdoor lighting so the security cameras can still capture images.
The installation of security system has two approaches-the covert and overt. In covert systems, the security cameras are hidden. In most cases, this system works for monitoring the activities of housekeepers, nannies and anyone who is on your home property.
Overt, on the other hand, have the surveillance cameras installed in conspicuous places. This works effectively for thieves as they would be too hesitant to rob the place due to the presence of home video security system.
Some wireless home video security may need to configure with a specific television channel for streaming. There is also the type that is plug-and-play, or wireless networks to communicate with computers.
IP-based system may need a specific IP camera. You should consider few factors for your IP cameras. Determine the distance and the width of the area you want covered for surveillance because that shall be the basis for knowing the right lens. The higher the focal length in millimeter, the smaller will be the field of view. You will also get more magnification.
The sensitivity of the camera should be considered as well. If you want to do security surveillance even at night, you may want to select low-light camera for home video security. The ‘lux’ rating determines how well a camera can see in dim light.
Auto-iris lens can adjust to the light in case you want to install the IP security cameras in a wide range of lighting conditions such as the outdoor. Also, the surveillance cameras come in digital PTZ or mechanical PTZ. PTZ stands for Pan Tilt Zoom.
Now, sometimes, there are fast-moving objects and you may want to catch its motion and speed. For this purpose, your home video security camera requires high frame rate. However, if you want a camera for general surveillance, a 1 or 2 frames per second is ideal.
Installing a home video security system can reduce the likelihood of break-ins. If indeed, a break-in happened, there are high chances of catching the culprit. Safety is the primary intent for getting video surveillance. It simply reduces crime.
