Answer
Good Thing I looked at the picture. Slight difference between a security system and a surveillance system. I hope you aren't expecting sirens to ring when someone walks in.
As for installation, unfortunately one of my customers bought the same unit from Costco here and they ended up having me install it.

Not a big deal, it is really easy. It comes with fixed length cables. 8 pin plug type similar to ethernet. The monitor itself is very large in comparison to anything modern I would sell. It does however have an RCA output for an extra monitor. The image quality is moderate at best, so don't expect any court submissable images or even the ability to recognize a face unless it is about 5 feet from the camera. Lenses are crap but if it is costs you are willing to cut...

Now for the actual valuable advice and things to consider.
- Don't aim the camera's at windows with the potential of bright sunlight behind them or the image will be washed out.
- Depth of field is a large consideration, do not expect the camera's to pick up detail over a large area - They are intended for small area's of focus. You may be able to see activity but images will be unintelligable.
- Florescent lights cause some image problems

If you do end up forking out the cash to have someone install a surveillance system for you, don't waste any money on this unit, any monkey with a screwdriver can install it why pay for that, have something decent put in - it will cost more than 300 bucks though.

Check out the video surveillance section on my website at http://www.keepsafesystems.ca. There is abut more information on there which may be of help

Good luck on your new business venture, it's a hard slug but definately worth it in the end.

Wireless Home Security Surveillance Camera system?




praveen


Hello,
For my house, i want to buy a wireless camera security surveillance system. Obviously, there are too many options. Can someone give me a feedback on any preferred brand or any feedback on what I should be looking for while buying this costly system? One potential option I found so far is
Swann SWDVK-825508 8-Channel Digital Video Recorder with Smartphone Viewing and 8 x PRO-550 Cameras

Answer
For consumer grade systems, Swann and Lorex make fine equipment. I installed a Swann 8 channel (using only 4 cameras - but planning to add 4 more cameras later). The included/free SmartPhone app for remote viewing works well but can use lots of battery power as it is a stream of video over wifi. The included 8 cameras in the system you listed don't have a very far night vision "throw" (about 10 feet). Another option to consider is this 4-camera, 8 channel DVR kit

plus four of these:

Any camera with a composite video feed will work including those from Lorex, Q-See and others.

Consider adding a VGA monitor or TV (I use the "extra" video inputs on 4 TVs located in different rooms of the house so visibility is not so limited to a single place).

The system you linked us to is not a "wireless" system. The connection between the cameras and the DVR is a wired connection. The cable connecting these items has a connector for the video; a connector for power and a connector for limited pan/tilt/zoom control. (The zoom is the part that actually works - you would need a pan/tilt head in order for that capability to work and the zoom is digital zoom - not optical zoom). Keep this in mind: A single cable with multiple connectors connects the camera to the DVR and power.

In a wireless video system, the camera needs power (wire #1). The video is sent to a base station wirelessly. The base station connects to the DVR (wire #2) and power (wire #3). A "wireless" security camera uses more wires than a wireless system.

The only thing "wireless" about the DVR kit in the link you provided us is that when the DVR is added to the computer network at your house, that wifi signal sending video to a smartphone or Windows computer is wireless.

Another option is to use IP network based security cameras but a dedicated computer (rather than a standalone DVR) is needed to be recording the video. These cameras tend to be a bit more expensive, especially it they are outdoor rated. And they need local camera power, too - so not exactly "wireless" either. Because they become a node of the local house's computer (IP) network, the complexity moves from the analog camera cabling to computer network implementation.

In either case, making the video stream available to a computer or a smartphone - locally or remotely - requires a decent knowledge of computer network configuration (especially if the computer network is to be secure).
