Home security camera System Checklist

1. Black/White or Hue? Color Cameras are more popular, due to their clearer identifications. But, in low light conditions, B/W cameras are more ideal, because they generally require less illumination. Newer forms of Day/Night cameras work as color camera during daytime and B/W at night. 2. What basic equipments are necessary to start video surveillance? Camera body, Lens, Mount, Cable, and Power Source. Some cameras (like dome and bullet type cameras) come with built-in lenses. You will also need CCTV monitor (or regular TV), quad splitter or switcher to combine a couple camera, recorder (like DVR), outdoor housing case any other accessories. Wireless systems look the best way to avoid cabling. Network based Web Cameras and DVRs are for remote surveillance. 3. What if I would like more than one surveillance camera? A quad splitter, 4 channel or 8 channel switcher, or multiplexer is available to combine multiple cameras into one monitor or camera. DVRs usually come with a built-in multiplexer. 4. Hidden Cameras If you want a concealed camera, you have two options; you can either build one with a mini or an ultra-mini camera, or buy only. Some ultra-mini cameras are only as big to be a quarter to hide better. Hidden cameras built-in clocks, radios, or smoke detectors are also available but are generally less affordable. Please note that, in most US states, using hidden cameras with audio in a covert way is prohibited. 5. Placing cameras outdoors You could use an outdoor housing case, with or without heater and/or motorized inflator. The heater and/or blower built-in housing cases generally require an unique power company. Some cameras are made water resistant and don't require separate housing cases. These also along with removable sunshields. 6. When are infrared cameras necessary? Economically commercialized infrared cameras, some also water-resistant to be installed outdoor, can see up to 40 to 80ft distance in total darkness. Forget about running use infrared illuminators, that illuminate as much 100ft (Color cameras, unless their IR filter is removed, don't work with infrared illuminators.) Infrared cameras be ordinary videocamera during day. Color infrared cameras work as B/W ones at night. 7. What an ideal angle to obtain lens to cover? Widely used and recommended angle of view from the lens for surveillance purpose is 72o to 78o. Narrower supplies you with clearer illustrations. Wide angles like 92o can cover more area but it might show distorted pictures. 8. Vari-focal vs. Aperture Focal length and focusing for vari-focal lens in order to be adjusted respectively while aperture focuses automatically when the focal length is adjusted. Manual zoom lens needs to be manually adjusted while motorized zoom lens can be controlled with a remote controlled. 9. Manual Iris as opposed to. Auto Iris If the lighting condition changes significantly and frequently, like the sun, a vehicular iris lens is vital. If the lighting remains same, a manual iris or a fixed iris lens is excellent. Most CCTV cameras accept DC auto iris lens while some kind of special cameras use video auto iris zoom lens. 10. Does someone need pinhole lens? A pinhole lens along with a tiny opening can be hidden their wall, ceiling or other objects. Some mini cameras have a built-in pinhole lens. To mount a pinhole lens to a customary camera is very expensive. 11. CCTV Monitor because. Standard TV If are generally use only 1 camera, a TV (which has a RCA video input) undoubtedly recommended. For more than 1 camera, if you utilize a processor like a quad splitter, a switcher, or a DVR (Digital Video Recorder), a TV would be fine. But, for special features like slave video outputs (to be linked with additional monitors), alarm systems, or for multiple inputs, professional CCTV monitors are preferable. 12. CRT vs. LCD Monitor Conventional CRT monitors are bulky and heavy while intensive testing . cheaper than LCD monitors which has higher quality. If you have enough budgets and wish to use one monitor for both CCTV and computer, LCD monitor is required. 17' & 19' are popular sizes for LCD sensors. 13. Monitor Input Connectors BNC usually used for connecting to both CRT and LCD monitors. These days, most LCD monitors a great S-Video input as well as a 15-pin Mini D-Sub for PC Signal input. 14. Wireless vs. Wired Transmission A wireless system is best in avoid cabling works, but can sometimes be affected by high voltage power lines, unseen razor waves, large machines like lathes, and metal wall structure. Wired transmission guarantees stable video. Coaxial cable is most designed for CCTV equipment. 15. 12VDC vs. 24VAC 24VAC is actually more professional and most CCTV cameras work along with a 24VAC power. Mini cameras, dome cameras, and bullet type cameras have proven to be 12VDC machine. Recently developed cameras have both 12VDC and 24VAC inputs. 16. Battery operated cameras Many small sized cameras use 12VDC battery pack; but it really really requires correctly matched polarity. You could also use a 'power cord' (easily available at any auto parts shop) that can draw 12VDC through difficulties cigarette richer. 17. Motion detection Most DVRs now include built-in motion detection software to trigger recording. May do program the sensitivity and detection zone. It works with any change in the pixels within the picture state of mind. You can also put in a hardware motion detector connected with the DVRs to trigger recording. 18. Pan, Tilt, and Zoom control A dome type camera that already has built-in PTZ difficult to install, maintain, and control. Absolutely also manage it on pc monitor the actual mouse when the PTZ system is connected towards the network with a video server. 19. Time Lapse VCR vs. DVR(Digital Video Recorder) Conventional Time Lapse VCR, despite the inconvenience in reviewing historic chinese medical specialists pictures, is much more economical when compared with DVR (Digital Video Recorder). DVRs are more popular for its convenience and picture superior quality. 20. Remote Surveillance over the Network Network DVR or Web Camera, related to the Internet or LAN and assigned with an IP address, can be monitored in a very remote place. DSL or T-1 lines are required for connected to the internet. 21. HD CCTV System As the tv Broadcasting changed to HD (High Definition) System, it is time for HD cameras arrive to the market. Still, the traditional standard resolution system doesn't accept HD cameras and also you have homework to prepare peripheral devices such as recorders to look at the HD cameras.
