1. Buy what you need. Every company has different CCTV requirements. Some don't need Surveillance at all. Banks must have top level CCTV including a Barber Shop might have 2 good cameras basically. Some businesses only rely on dummy cameras, and a dummy "protected by" warning. So before you have a quotation think "what do I actually need? What are my objectives".
2. Locate surveillance cameras correctly. Is the camera in the right placement? Do you want to capture the face or the back of the head? Surveillance cameras for monitoring purposes should be raised above eye level so they could see more. Cameras for verification and recognition should be at eye level as a result the best image of the face is taken.
3. Buy the right surveillance camera and lens. Can you end up picking right lens? Some people that try to do it themselves purchase CCTV packages off a shelf. These kinds of packages usually have 4 surveillance cameras, all with the same wide lens, which is unable to be adjusted. Wide lenses may only monitor. Wide lenses simply cannot be used for recognition as well as identification, because they will not likely give a clear picture of the person. Evidence without recognition together with identification quality images will not likely stand up in court.
4. Purchase the right Digital Video Recorder (Digital video recorder). If the recording of live images is required then a better specification of resolution - image quality - is necessary of the DVR. Cameras have four various technical levels of resolution. Top quality is D1 then 2CIF, CIF and QCIF. Resolution quality needs to be balanced against recording speed to produce higher specification objectives. Live images need at least 25FPS (frames per second). We suggest that identification cameras should need 2CIF resolution, at least, with the maximum frame-rate, and that monitoring cameras apply CIF quality at least. The Digital video recorder must support these specifications. Most DVR manufacturers claim they achieve resolution and frame pace targets, but some don't essentially do the job required.
5. Better not try to do it yourself. Several of people think that CCTV setting up is easy, but as professionals we know it is not. CCTV technology is growing fast, so if you happen to be not informed about up to date tools, and recent technical developments you will miss out. Undoubtedly you can buy a package and a manual in an electronic devices store, but are you in no doubt it's what you require, and are you sure it is going to work? How much instance you will spend? Would it be worth of it? Your result will in all probability be a maximum 10% of potential as well as your money will be lost. An excellent professional will achieve NSI A regular. Can you?
