DVR H.264 e MPEG4 su smartphone - www.hrcctv.com

Ricorderete il video dedicato alla differenza tra un PC based ed un DVR tradizionale. Ora esiste un'ulteriore possibilità grazie ai DVR LCT che permettono direttamente la visualizzazione su telefonino. La linea LCT comprende due diverse categorie di prodotto: l'LCTVR6104 è un MPEG4, l'LCTVR8208 e l'LCTVR8216 sono H.264. Nei singoli post dedicati ai prodotti trovate tutte le caratteristicche ma è forse il caso di segnalare l'uscita VGA che permette di utilizzare un qualunque monitor da PC e l'utilizzo degli hard disk SATA che sostituisco i vecchi PATA e IDE, che ben presto saranno obsoleti. In più i modelli ad 8 e 16 canali dispongono di un un'uscita SPOT programmabile, un'uscita ausiliaria che è possibile gestire con facilità. Su tutti e tre i modelli è possibile visualizzare i file, oltre che tramite il software a corredo e tramite Internet Explorer, anche attraverso il proprio smartphone. Uno smartphone non è un semplice videofonino. Si tratta di un vero e proprio computer palmare dotato di connettività. Tramite GSM, GPRS, EDGE oppure UMTS è possibile telefonare ma anche entrare in internet sfruttando la line cellulare. E proprio tramite questa si possono anche visualizzare i DVR LCT. La soluzione ideale per chi viaggia ed ha necessità di tenere sempre sottocntrollo, in tempo reale, la propria casa o la propria azienda.

How to Choose a Home Or Business Video Surveillance System

!±8± How to Choose a Home Or Business Video Surveillance System

There are various kinds of Security Systems with kinds of functions in the online stores, however, which one is best for you? Before your decision, ask yourself for several questions.

For Camera:
1. Where are you going to mount the camera?
Then the answer can help you decide to choose how many home dome cameras and how many outdoor bullet &weatherproof cameras.

2. How long is the visible and night vision distance?
Usually, the visible distance of cameras can be up to 50', 80', 135', etc. Take a look the IR Night Vision as 1/3" CCD for an instance:
1) 1/3" CCD & 3.6mm lens camera ( 15m IR night vision)
2) 1/3" CCD & 6mm lens camera ( 20m IR night vision)
3) 1/3" CCD & 8mm lens camera ( 25m-30m IR night vision)
4) 1/3" CCD & 12mm lens camera ( 40m-60m IR night vision)
5) 1/3" CCD & 25mm lens camera ( 100m-120m IR night vision)

3. How much the viewing angle?
Most video surveillance cameras are installed in one location permanently. For this case, fixed-focus lenses are the most cost-effective. If you want to be able to move your camera, variable focus lenses are adjustable, letting you change your field of view when you adjust the camera. If you want to be able to move the camera remotely, you'll need a pan/tilt/zoom (PTZ) camera. On the other side, the price is much higher than the standard ones.

4. How much details of the camera image?
Of cos, the resolutions of the cameras are very important too. Generally speaking, 380TVL is low-end, 420TVL/480TVL is good for security work, 540TVL is very high quality. If you're going to want to see detail, upgrading to a higher resolution is a good choice.

For Digital Video Recorder:
1. How many locations do you want to watch?
This also helps you to decide how many cameras and what kind of cameras will you choose. There are usually 4 channel, 8 channel, 16 channel, and 32 channel.

2. Does remote access need or just for local monitoring?
The MPEG4 & H.264 are the two mainly popular video compression formats for digital video recorders. However, you need to make clear the difference of these two formats: MPEG4 (good for local storage) V.S. H.264 (Network transmission, remote access needed). However, personally, I recommend on H.264, which is widely used with remote access control.

3. How long do you need to save your recordings for?
500GB and 1 TB are hard drives are usually installed in the DVRs. Generally speaking, 500GB HDD is enough for your home and small business.
